202-651: Apollo 12 (November 14–24, 1969) was the sixth crewed flight in the United States Apollo program and the second to land on the Moon . It was launched on November 14, 1969, by NASA from the Kennedy Space Center , Florida . Commander Charles "Pete" Conrad and Lunar Module Pilot Alan L. Bean completed just over one day and seven hours of lunar surface activity while Command Module Pilot Richard F. Gordon remained in lunar orbit. Apollo 12 would have attempted

404-502: A grand jury on an aggravated assault with a deadly weapon charge but was not charged with any additional hate crime charge. A large student and faculty Pro-Palestinian protest occurred on April 24, 2024, demanding a ceasefire in the Israel-Hamas War and that the university divest from companies profiting from Israel's actions. The protests occurred amidst the ongoing nationwide demonstrations on college campuses . In response,

606-532: A mission module cabin separate from the command module (piloting and reentry cabin), and a propulsion and equipment module . On August 30, a feasibility study competition was announced, and on October 25, three study contracts were awarded to General Dynamics/Convair , General Electric , and the Glenn L. Martin Company . Meanwhile, NASA performed its own in-house spacecraft design studies led by Maxime Faget , to serve as

808-607: A selfie of the two of them with the probe, but when the time came to use it, could not locate it among the lunar samples they had already placed in their Hand Tool Carrier. Before returning to the LM's vicinity, Conrad and Bean went to Block crater , within Surveyor crater. The second EVA lasted 3 hours, 49 minutes, 15 seconds, during which they traveled 4,300 feet (1,300 m). During the EVAs, Conrad and Bean went as far as 1,350 feet (410 m) from

1010-413: A 10 PM curfew for all protests, directly contradicting prior guidelines. Initially, the university told students and faculty that arrested protestors would no longer be allowed on campus, but retracted the statement two hours later, stating that they would be allowed "academic" access, only to then announce a change to full access for university affiliates. Additionally, the university temporarily suspended

1212-768: A 130-million-cubic-foot (3,700,000 m ) Vertical Assembly Building (VAB). in which the space vehicle (launch vehicle and spacecraft) would be assembled on a mobile launcher platform and then moved by a crawler-transporter to one of several launch pads. Although at least three pads were planned, only two, designated A   and   B, were completed in October 1965. The LOC also included an Operations and Checkout Building (OCB) to which Gemini and Apollo spacecraft were initially received prior to being mated to their launch vehicles. The Apollo spacecraft could be tested in two vacuum chambers capable of simulating atmospheric pressure at altitudes up to 250,000 feet (76 km), which

1414-580: A U.S. flag on the Moon , Conrad and Bean devoted much of the remainder of the first EVA to deploying the Apollo Lunar Surface Experiments Package (ALSEP). There were minor difficulties with the deployment. Bean had trouble extracting the RTG's plutonium fuel element from its protective cask, and the astronauts had to resort to the use of a hammer to hit the cask and dislodge the fuel element. Some of

1616-471: A burn to alter the CSM's orbit to compensate for the rotation of the Moon, though at times he had difficulty communicating with Houston since Conrad and Bean were using the same communications circuit. Once the two moonwalkers had returned to the LM, Gordon executed the burn, which ensured he would be in the proper position to rendezvous with the LM when it launched from the Moon. While alone in orbit, Gordon performed

1818-465: A commitment on America's response to the Soviets. On April 20, Kennedy sent a memo to Vice President Lyndon B. Johnson , asking Johnson to look into the status of America's space program, and into programs that could offer NASA the opportunity to catch up. Johnson responded approximately one week later, concluding that "we are neither making maximum effort nor achieving results necessary if this country

2020-608: A contentious dispute erupted between Texas Governor James E. Ferguson and the University of Texas over faculty appointments. Ferguson's attempt to influence these appointments led to a retaliatory veto of the university's budget, jeopardizing its operations. Subsequently, Ferguson was impeached by the Texas House of Representatives , convicted by the Senate on charges including misapplication of public funds, and removed from office. In 1921,

2222-454: A gauge to judge and monitor the three industry designs. In November 1960, John F. Kennedy was elected president after a campaign that promised American superiority over the Soviet Union in the fields of space exploration and missile defense . Up to the election of 1960, Kennedy had been speaking out against the " missile gap " that he and many other senators said had developed between

2424-646: A general system of education when circumstances allowed. After Texas was annexed , the Seventh Texas Legislature passed O.B. 102 on February 11, 1858, allocating $ 100,000 in United States bonds from the Compromise of 1850 for the University of Texas. The Civil War delayed fund repayment, leaving the university with only $ 16,000 by 1865. Nevertheless, the Texas Constitution of 1876 reaffirmed

2626-488: A great new American enterprise—time for this nation to take a clearly leading role in space achievement, which in many ways may hold the key to our future on Earth. ...   I believe that this nation should commit itself to achieving the goal, before this decade is out, of landing a man on the Moon and returning him safely to the Earth. No single space project in this period will be more impressive to mankind, or more important in

2828-504: A historically black college, "a place where he is loved". The University of Texas at Austin has experienced a wave of new construction recently with several significant buildings. On April 30, 2006, the school opened the Blanton Museum of Art . In August 2008, the AT&;T Executive Education and Conference Center opened, with the hotel and conference center forming part of a new gateway to

3030-412: A hybrid trajectory meant that Apollo 12 took 8 hours longer to go from trans-lunar injection to lunar orbit. Apollo 12 entered a lunar orbit of 170.2 by 61.66 nautical miles (315.2 by 114.2 km; 195.9 by 70.96 mi) with an SPS burn of 352.25 seconds at mission time 83:25:26.36. On the first lunar orbit, there was a television transmission that resulted in good-quality video of the lunar surface. On

3232-458: A limited Earth orbital mission, Apollo would carry three. Possible missions included ferrying crews to a space station , circumlunar flights , and eventual crewed lunar landings . In July 1960, NASA Deputy Administrator Hugh L. Dryden announced the Apollo program to industry representatives at a series of Space Task Group conferences. Preliminary specifications were laid out for a spacecraft with

3434-549: A lunar landing had been removed by Apollo 11's success, NASA might have waited until December for the next opportunity to go to the Surveyor crater. Lightning struck the Saturn V 36.5 seconds after lift-off, triggered by the vehicle itself. The static discharge caused a voltage transient that knocked all three fuel cells offline, meaning the spacecraft was being powered entirely from its batteries, which could not supply enough current to meet demand. A second strike at 52 seconds knocked out

3636-437: A nearby tent. Afterwards, the astronauts' performance in choosing samples and taking photographs would be critiqued. To the frustration of the astronauts, the scientists kept changing the photo documentation procedures; after the fourth or fifth such change, Conrad required that there be no more. After the return of Apollo 11, the Apollo 12 crew was able to view the lunar samples, and be briefed on them by scientists. As Apollo 11

3838-425: A one-sentence job description, "The flight director may take any actions necessary for crew safety and mission success." Capsule communicators (CAPCOMs) were Scott, Worden, Irwin, Carr, Gibson, Weitz and Don Lind . The landing site selection process for Apollo 12 was greatly informed by the site selection for Apollo 11. There were rigid standards for the possible Apollo 11 landing sites, in which scientific interest

4040-569: A precise landing at their expected location within walking distance of the Surveyor 3 robotic probe, which had landed on April 20, 1967. In making a pinpoint landing, they showed that NASA could plan future missions in the expectation that astronauts could land close to sites of scientific interest. Conrad and Bean carried the Apollo Lunar Surface Experiments Package , a group of nuclear-powered scientific instruments, as well as

4242-509: A public school price, having been ranked in virtually every list of "Public Ivies" since Richard Moll coined the term in his 1985 book Public Ivies: A Guide to America's best public undergraduate colleges and universities . The seven other "Public Ivy" universities, according to Moll, were the College of William & Mary, Miami University, the University of California , the University of Michigan ,

4444-404: A reaction control system. The initial LM model weighed approximately 33,300 pounds (15,100 kg), and allowed surface stays up to around 34 hours. An extended lunar module (ELM) weighed over 36,200 pounds (16,400 kg), and allowed surface stays of more than three days. The contract for design and construction of the lunar module was awarded to Grumman Aircraft Engineering Corporation , and

4646-578: A result of a student referendum passed in 2006 which raised student fees by $ 65 per semester. In 2012, the Moody Foundation awarded the College of Communication $ 50 million, the largest endowment any communication college has received, so naming it the Moody College of Communication. The university operates two public radio stations, KUT with news and information, and KUTX with music, via local FM broadcasts as well as live streaming audio over

4848-554: A spacecraft that could meet it while minimizing risk to human life, limiting cost, and not exceeding limits in possible technology and astronaut skill. Four possible mission modes were considered: In early 1961, direct ascent was generally the mission mode in favor at NASA. Many engineers feared that rendezvous and docking, maneuvers that had not been attempted in Earth orbit , would be nearly impossible in lunar orbit . LOR advocates including John Houbolt at Langley Research Center emphasized

5050-574: A successful splashdown . The commander of the all- Navy Apollo 12 crew was Charles "Pete" Conrad , who was 39 years old at the time of the mission. After receiving a bachelor's degree in aeronautical engineering from Princeton University in 1953, he became a naval aviator, and completed United States Naval Test Pilot School at Patuxent River Naval Air Station . He was selected in the second group of astronauts in 1962, and flew on Gemini 5 in 1965, and as command pilot of Gemini 11 in 1966. Command Module Pilot Richard "Dick" Gordon , 40 years old at

5252-700: A total of 155 Olympic medals . The idea of a public university in Texas was first mentioned in the 1827 constitution of the Mexican state of Coahuila y Tejas , which promised public education in the arts and sciences under Title 6, Article 217, but no action was taken. After Texas gained independence from Mexico in 1836, the Constitution of the Republic emphasized Congress's duty, in Section 5 of its General Provisions, to establish

5454-561: A transition to online classes for the rest of the spring semester after 49 confirmed COVID-19 cases emerged from students' travels to Cabo San Lucas, Mexico, during spring break. Throughout the summer, the university reported over 400 cases and its first COVID-19-related death, a custodial worker. The fall 2020 semester consisted of a majority of online courses through platforms like Zoom. On August 6, 2020, UT Austin initiated plans for free COVID-19 tests for all students. UT Austin returned to primarily in-person classes and campus activities for

6464-467: Is to reach a position of leadership." His memo concluded that a crewed Moon landing was far enough in the future that it was likely the United States would achieve it first. On May 25, 1961, twenty days after the first US crewed spaceflight Freedom 7 , Kennedy proposed the crewed Moon landing in a Special Message to the Congress on Urgent National Needs : Now it is time to take longer strides—time for

6666-648: The Apollo command and service module , succeeding the Mercury program . A lunar landing became the focus of the program only in 1961. Thereafter Project Gemini instead followed the Mercury program to test and study advanced crewed spaceflight technology. The Apollo program was conceived during the Eisenhower administration in early 1960, as a follow-up to Project Mercury. While the Mercury capsule could support only one astronaut on

6868-537: The Atomic Energy Commission . Containing plutonium , the RTG flown on Apollo 12 was the first use of atomic energy on a crewed NASA spacecraft—some NASA and military satellites had previously used similar systems. The plutonium core was brought from Earth in a cask attached to an LM landing leg, a container designed to survive re-entry in the event of an aborted mission, something NASA considered unlikely. The cask would survive re-entry on Apollo 13 , sinking in

The Longhorns have won four NCAA Division I National Football Championships, six NCAA Division I National Baseball Championships, thirteen NCAA Division I National Men's Swimming and Diving Championships, and

7676-526: The S-IVB , was intended to fly into solar orbit. The S-IVB auxiliary propulsion system was fired, with the intent that the Moon's gravity would slingshot the stage into solar orbit. Due to an error, the S-IVB flew past the Moon at too high an altitude to achieve Earth escape velocity. It remained in a semi-stable Earth orbit until it finally escaped Earth orbit in 1971, but briefly returned to Earth orbit 31 years later. It

7878-470: The SPS ." Ironically, just such a failure happened on Apollo 13 when an oxygen tank explosion left the CSM without electrical power. The lunar module provided propulsion, electrical power and life support to get the crew home safely. Faget's preliminary Apollo design employed a cone-shaped command module, supported by one of several service modules providing propulsion and electrical power, sized appropriately for

The LAD returned only a small amount of useful data due to the failure of its power supply soon after activation. The LSM was deactivated on June 14, 1974, as was the other LSM deployed on the Moon, from Apollo 15. All powered ALSEP experiments that remained active were deactivated on September 30, 1977, principally because of budgetary constraints. With President Richard Nixon in attendance,

9292-726: The White Sands Missile Range between May 1964 and January 1966. Saturn I, the first US heavy lift launch vehicle, was initially planned to launch partially equipped CSMs in low Earth orbit tests. The S-I first stage burned RP-1 with liquid oxygen (LOX) oxidizer in eight clustered Rocketdyne H-1 engines, to produce 1,500,000 pounds-force (6,670 kN) of thrust. The S-IV second stage used six liquid hydrogen-fueled Pratt & Whitney RL-10 engines with 90,000 pounds-force (400 kN) of thrust. The S-V third stage flew inactively on Saturn I four times. The first four Saturn I test flights were launched from LC-34, with only

9494-480: The command and service module (CSM), and all three landed safely on Earth in the Pacific Ocean on July 24. Five subsequent Apollo missions also landed astronauts on the Moon, the last, Apollo 17 , in December 1972. In these six spaceflights, twelve people walked on the Moon . Apollo ran from 1961 to 1972, with the first crewed flight in 1968. It encountered a major setback in 1967 when an Apollo 1 cabin fire killed

9696-450: The "5" indicating Saturn V. The three-stage Saturn V was designed to send a fully fueled CSM and LM to the Moon. It was 33 feet (10.1 m) in diameter and stood 363 feet (110.6 m) tall with its 96,800-pound (43,900 kg) lunar payload. Its capability grew to 103,600 pounds (47,000 kg) for the later advanced lunar landings. The S-IC first stage burned RP-1/LOX for a rated thrust of 7,500,000 pounds-force (33,400 kN), which

9898-546: The "8-ball" attitude indicator . The telemetry stream at Mission Control was garbled, but the Saturn V continued to fly normally; the strikes had not affected the Saturn V instrument unit guidance system, which functioned independently from the CSM. The astronauts unexpectedly had a board red with caution and warning lights, but could not tell exactly what was wrong. The Electrical, Environmental and Consumables Manager (EECOM) in Mission Control, John Aaron , remembered

10100-451: The 1960s, President Kennedy's target date. The LOR method had the advantage of allowing the lander spacecraft to be used as a "lifeboat" in the event of a failure of the command ship. Some documents prove this theory was discussed before and after the method was chosen. In 1964 an MSC study concluded, "The LM [as lifeboat]   ... was finally dropped, because no single reasonable CSM failure could be identified that would prohibit use of

10302-605: The 2009–2010 academic year, the university awarded a total of 13,215 degrees: 67.7% bachelor's degrees , 22.0% master's degrees, 6.4% doctoral degrees , and 3.9% Professional degrees.

The main campus has 150 buildings totaling over 18,000,000 square feet (1,700,000 m ). One of the university's most visible features is the Beaux-Arts Main Building , including a 307-foot (94 m) tower designed by Paul Philippe Cret . Completed in 1937,

10908-589: The ALSEP packages proved hard to deploy, though the astronauts were successful in all cases. With the PSE able to detect their footprints as they headed back to the LM, the astronauts secured a core tube full of lunar material, and collected other samples. The first EVA lasted 3 hours, 56 minutes and 3 seconds. Four possible geologic traverses had been planned, the variable being where the LM might set down. Conrad had landed it between two of these potential landing points, and during

11110-617: The ALSEP, required humans. In 1966, a contract to design and build the ALSEPs was awarded to the Bendix Corporation . Due to the limited time the Apollo 11 crew would have on the lunar surface, a smaller suite of experiments was flown, known as the Early Apollo Surface Experiment Package (EASEP). Apollo 12 was the first mission to carry an ALSEP; one would be flown on each of the subsequent lunar landing missions, though

11312-410: The Apollo 12 launch vehicle, bringing the number to 1,365. The entire vehicle, including the spacecraft, weighed 6,487,742 pounds (2,942,790 kg) at launch, an increase from Apollo 11's 6,477,875 pounds (2,938,315 kg). Of this figure, the spacecraft weighed 110,044 pounds (49,915 kg), up from 109,646 pounds (49,735 kg) on Apollo 11. After LM separation, the third stage of the Saturn V,

11514-476: The CSM and LM of Apollo 11, and those of Apollo 12, were few and minor. A hydrogen separator was added to the CSM to stop the gas from entering the potable water tank—Apollo 11 had had one, though mounted on the water dispenser in the CM's cabin. Gaseous hydrogen in the water had given the Apollo 11 crew severe flatulence. Other changes included the strengthening of the recovery loop attached following splashdown, meaning that

11716-402: The CSM maneuvered away. Under control from Earth, the LM's remaining propellant was depleted in a burn that caused it to impact the Moon 39 nautical miles (72 km; 45 mi) from the Apollo 12 landing point. The seismometer the astronauts had left on the lunar surface registered the resulting vibrations for more than an hour. The crew stayed another day in lunar orbit taking photographs of

The stage fired its engines to leave the vicinity of the spacecraft, a change from Apollo 11, where the SM's Service Propulsion System (SPS) engine was used to distance it from the S-IVB. As there were concerns the LM might have been damaged by the lightning strikes, Conrad and Bean entered it on

13332-402: The LM at 110:32:36.2 (06:54:36 UT on November 19, 1969), just 535 feet (163 m) from the Surveyor probe. This achieved one objective of the mission, to perform a precision landing near the Surveyor craft. The lunar coordinates of the landing site were 3.01239° S latitude, 23.42157° W longitude. The landing caused high velocity sandblasting of the Surveyor probe. It was later determined that

Once that was accomplished, Gordon sent his congratulations and, on the next orbit, was able to spot both the LM and the Surveyor on the ground and convey their locations to Houston. During the first EVA, Gordon prepared for a plane change maneuver ,

13938-457: The LM. This was the start of geology traverse planning that on later missions became a considerable effort involving several organizations. The stages of the lunar module, LM–6, were delivered to Kennedy Space Center (KSC) on March 24, 1969, and were mated to each other on April 28. Command module CM–108 and service module SM–108 were delivered to KSC on March 28, and were mated to each other on April 21. Following installation of gear and testing,

14140-465: The Lunar Multispectral Photography Experiment, using four Hasselblad cameras arranged in a ring and aimed through one of the CM's windows. With each camera having a different color filter, simultaneous photos would be taken by each, showing the appearance of lunar features at different points on the spectrum . Analysis of the images might reveal colors not visible to the naked eye or detectable with ordinary color film, and information could be obtained about

14342-423: The Main Building is in the middle of campus. The tower usually appears illuminated in white light in the evening but is lit burnt orange for various special occasions, including athletic victories and academic accomplishments; conversely, it is darkened for solemn occasions. At the top of the tower is a carillon of 56 bells, the largest in Texas. Songs are played on weekdays by student carillonneurs, in addition to

14544-411: The Moon and provide data about the Moon's structure. The Apollo 12 spacecraft consisted of Command Module 108 and Service Module 108 (together Command and Service Modules 108, or CSM–108), Lunar Module 6 (LM–6), a Launch Escape System (LES), and Spacecraft-Lunar Module Adapter 15 (SLA–15). The LES contained three rocket motors to propel the CM to safety in the event of an abort shortly after launch, while

14746-427: The Moon at a known location, and projected to be equivalent to the explosive force of one ton of TNT. The ALSEP experiments left on the Moon by Apollo 12 were connected to a Central Station, which contained a transmitter, receiver, timer, data processor, and equipment for power distribution and control of the experiments. The equipment was powered by SNAP-27 , a radioisotope thermoelectric generator (RTG) developed by

14948-595: The Moon by the end of 1969 required the most sudden burst of technological creativity, and the largest commitment of resources ($ 25 billion; $ 182 billion in 2023 US dollars) ever made by any nation in peacetime. At its peak, the Apollo program employed 400,000 people and required the support of over 20,000 industrial firms and universities. On July 1, 1960, NASA established the Marshall Space Flight Center (MSFC) in Huntsville, Alabama . MSFC designed

15150-617: The Moon in this decade and do the other things, not because they are easy, but because they are hard; because that goal will serve to organize and measure the best of our energies and skills; because that challenge is one that we are willing to accept, one we are unwilling to postpone, and one we intend to win   ... The MSC was completed in September 1963. It was renamed by the US Congress in honor of Lyndon Johnson soon after his death in 1973. It also became clear that Apollo would outgrow

15352-676: The Moon, crippling the CSM. The crew barely managed a safe return to Earth by using the lunar module as a "lifeboat" on the return journey. Apollo used the Saturn family of rockets as launch vehicles, which were also used for an Apollo Applications Program , which consisted of Skylab , a space station that supported three crewed missions in 1973–1974, and the Apollo–Soyuz Test Project, a joint United States - Soviet Union low Earth orbit mission in 1975. Apollo set several major human spaceflight milestones . It stands alone in sending crewed missions beyond low Earth orbit . Apollo 8

15554-571: The October Cuban Missile Crisis , and fear of Kennedy's support for Webb. NASA announced the selection of Grumman as the LEM contractor in November 1962. Space historian James Hansen concludes that: Without NASA's adoption of this stubbornly held minority opinion in 1962, the United States may still have reached the Moon, but almost certainly it would not have been accomplished by the end of

15756-791: The Office of Manned Space Flight (OMSF). On July 23, 1963, Webb announced Mueller's appointment as Deputy Associate Administrator for Manned Space Flight, to replace then Associate Administrator D. Brainerd Holmes on his retirement effective September 1. Under Webb's reorganization, the directors of the Manned Spacecraft Center ( Gilruth ), Marshall Space Flight Center ( von Braun ), and the Launch Operations Center ( Debus ) reported to Mueller. Based on his industry experience on Air Force missile projects, Mueller realized some skilled managers could be found among high-ranking officers in

15958-432: The Office of Technology Commercialization, a technology transfer center which serves as the bridge between laboratory research and commercial development. In 2009, the university created nine new start-up companies to commercialize technology developed at the university and has created 46 start-ups in the past seven years. License agreements generated $ 10.9 million in revenue for the university in 2009. In January 2020,

16160-570: The SAT and ACT standardized exams were "a proven differentiator that is in each student's and the University's best interest." On April 2, 2024, the University of Texas at Austin announced additional adjustments in compliance with Senate Bill 17, particularly in response to a letter from March 26, 2024 from Texas State Senator Brandon Creighton , which led to the layoff of approximately 60 individuals, most of whom formerly worked in DEI-related programs, and

16362-522: The SLA housed the LM and provided a structural connection between the Saturn V and the LM. The SLA was identical to Apollo 11's, while the LES differed only in the installation of a more reliable motor igniter. The CSM was given the call sign Yankee Clipper , while the LM had the call sign Intrepid . These sea-related names were selected by the all-Navy crew from several thousand proposed names submitted by employees of

16564-454: The Saturn V. The Saturn IB could send over 40,000 pounds (18,100 kg) into low Earth orbit, sufficient for a partially fueled CSM or the LM. Saturn IB launch vehicles and flights were designated with an AS-200 series number, "AS" indicating "Apollo Saturn" and the "2" indicating the second member of the Saturn rocket family. Saturn V launch vehicles and flights were designated with an AS-500 series number, "AS" indicating "Apollo Saturn" and

16766-509: The Soviet Union and the United States due to the inaction of President Eisenhower. Beyond military power, Kennedy used aerospace technology as a symbol of national prestige, pledging to make the US not "first but, first and, first if, but first period". Despite Kennedy's rhetoric, he did not immediately come to a decision on the status of the Apollo program once he became president. He knew little about

16968-584: The Surveyor 3 probe had landed. Fearing treacherous footing or that the probe might topple on them, they approached Surveyor cautiously, descending into the shallow crater some distance away and then following a contour to reach the craft, but found the footing solid and the probe stable. They collected several pieces of Surveyor, including the television camera, as well as taking rocks that had been studied by television. Conrad and Bean had procured an automatic timer for their Hasselblad cameras, and had brought it with them without telling Mission Control, hoping to take

17170-461: The Surveyor crater in its center, but had feared he would see nothing recognizable. He was astonished to see the Snowman right where it should be, meaning they were directly on course. He took over manual control, planning to land the LM, as he had in simulations, in an area near the Surveyor crater that had been dubbed "Pete's Parking Lot", but found it rougher than expected. He had to maneuver, and landed

17372-701: The United States, and Latin America. The Perry–Castañeda Library , which houses the central University Libraries operations and the Perry–Castañeda Library Map Collection , is at the heart of campus. The Benson Latin American Collection holds the largest collection of Latin American materials among US university libraries, and maintains substantial digital collections. The University of Texas at Austin has an extensive tunnel system that links

17574-619: The University of Texas was inducted into the Association of American Universities . During World War II , the University of Texas was one of 131 colleges and universities nationally that took part in the V-12 Navy College Training Program which offered students a path to a Navy commission. Additionally, to facilitate the wartime effort, academic calendars were compressed, allowing for accelerated graduation. After Brown v. Board of Education in 1954, Houston, Texas, area teen Marion Ford had been accepted to become one of

17776-458: The ability to perform pinpoint landings was essential if Apollo's exploration program was to be carried out, and on July 25, 1969, Apollo Program Manager Samuel Phillips designated what became known as Surveyor crater as the landing site, despite the unanimous opposition of members of two site selection boards. To locate Surveyor 3, NASA invited Ewen Whitaker , who together with Gerard Kuiper worked on multiple moon atlases. Whitaker had found

17978-448: The best chance of flying in space again. Bean did so—Conrad commanded Skylab 2 , the first crewed mission to the space station, while Bean commanded Skylab 3 . Gordon, though, still hoped to walk on the Moon and remained with the Apollo program, serving as backup commander of Apollo 15. He was the likely commander of Apollo 18 , but that mission was canceled and he did not fly in space again. The Apollo 12 command module Yankee Clipper ,

18180-405: The buildings on campus. Constructed c.  1928 under the supervision of UT engineering professor Carl J. Eckhardt Jr., then head of the physical plant, the tunnels have grown along with the campus. They measure approximately six miles in length. The tunnel system is used for communications and utility service. It is closed to the public and guarded by silent alarms . Since the late 1940s,

18382-469: The center was conducted by Kurt H. Debus , a member of Wernher von Braun 's original V-2 rocket engineering team. Debus was named the LOC's first Director. Construction began in November 1962. Following Kennedy's death , President Johnson issued an executive order on November 29, 1963, to rename the LOC and Cape Canaveral in honor of Kennedy. The LOC included Launch Complex 39 , a Launch Control Center , and

18584-426: The clear goal of a crewed landing replacing the more nebulous goals of space stations and circumlunar flights, NASA decided that, in order to make progress quickly, it would discard the feasibility study designs of Convair, GE, and Martin, and proceed with Faget's command and service module design. The mission module was determined to be useful only as an extra room, and therefore unnecessary. They used Faget's design as

18786-454: The closure on April 2, 2024, leading the charter school to be moved to the College of Education . On February 4, 2024, a Palestinian-American student at a pro-Palestinian protest at the campus was stabbed, receiving non-life-threatening injuries. The attacker used a racial slur against the protestors and the attack was investigated as a hate crime. A month later the attacker was indicted by

18988-446: The components that were included would vary. Apollo 12's ALSEP was to be deployed at least 300 feet (91 m) away from the LM to protect the instruments from the debris that would be generated when the ascent stage of the LM took off to return the astronauts to lunar orbit. Apollo 12's ALSEP included a Lunar Surface Magnetometer (LSM), to measure the magnetic field at the Moon's surface, a Lunar Atmosphere Detector (LAD, also known as

19190-407: The composition of sites that would not soon be visited by humans. Among the sites studied were contemplated landing points for future Apollo missions. LM Intrepid lifted off from the Moon at mission time 143:03:47.78, or 14:25:47 UT on November 20, 1969; after several maneuvers, CSM and LM docked three and a half hours later. At 147:59:31.6, the LM ascent stage was jettisoned, and shortly thereafter

19392-429: The confirmed arrest of 57 protesters, including a photojournalist for Fox 7 Austin, with several more detained. Charges were then dismissed against 46 protesters the next day, leading to their subsequent release, with the charges against the remaining 11 protesters dropped on April 26, 2024. This decision received sharp backlash, including from general faculty, staff, students, several Democratic legislators for

19594-449: The contract to build the CSM, and also the second stage of the Saturn V launch vehicle for NASA. Because the CSM design was started early before the selection of lunar orbit rendezvous, the service propulsion engine was sized to lift the CSM off the Moon, and thus was oversized to about twice the thrust required for translunar flight. Also, there was no provision for docking with the lunar module. A 1964 program definition study concluded that

19796-421: The crater in which the Surveyor 3 probe had landed in 1967 to allow the astronauts to cut parts from it for return to Earth. The site was otherwise suitable and had scientific interest. Given that Apollo 11 had landed several miles off-target, though, some NASA administrators feared Apollo 12 would land far enough away that the astronauts could not reach the probe, and the agency would be embarrassed. Nevertheless,

19998-407: The crew names are on a wide gold border, with a small blue trim. Blue and gold are traditional U.S. Navy colors. The patch has four stars on it – one each for the three astronauts who flew the mission and one for Clifton Williams, the original LMP on Conrad's crew who was killed in 1967 and would have flown the mission. The star was placed there at the suggestion of his replacement, Bean. The insignia

20200-460: The crew of Apollo 15 . For Apollo, a third crew of astronauts, known as the support crew, was designated in addition to the prime and backup crews used on projects Mercury and Gemini. Slayton created the support crews because James McDivitt , who would command Apollo 9, believed that, with preparation going on in facilities across the US, meetings that needed a member of the flight crew would be missed. Support crew members were to assist as directed by

20402-588: The eastern side of the main campus, the Lyndon Baines Johnson Library and Museum is one of 13 presidential libraries administered by the National Archives and Records Administration . A statue of Martin Luther King Jr. was unveiled on campus in 1999 and subsequently vandalized. By 2004, John Butler, a professor at the McCombs School of Business suggested moving it to Morehouse College ,

20604-498: The elimination of the newly-renamed Division of Campus and Community Engagement. Students, faculty, staff, and outside critics denounced the university's over-compliance with the anti-DEI law, since the university had already been compliant since January 1, 2024. At a UT Austin Faculty Council meeting on April 15, 2024, in response to mounting criticism, President Jay Hartzell stated the additional changes were made in response to

20806-425: The end of the mission. After systems checks in Earth orbit, performed with great care because of the lightning strikes, the trans-lunar injection burn, made with the S-IVB, took place at 02:47:22.80 into the mission, setting Apollo 12 on course for the Moon. An hour and twenty minutes later, the CSM separated from the S-IVB, after which Gordon performed the transposition, docking, and extraction maneuver to dock with

21008-425: The entire crew during a prelaunch test. After the first successful landing, sufficient flight hardware remained for nine follow-on landings with a plan for extended lunar geological and astrophysical exploration. Budget cuts forced the cancellation of three of these. Five of the remaining six missions achieved successful landings, but the Apollo 13 landing had to be aborted after an oxygen tank exploded en route to

21210-492: The fall 2021 semester, implementing safety protocols like testing requirements and vaccination incentives to ensure a safe return amid the ongoing pandemic. In 2024, after four years of test-optional admissions for undergraduate applications due to the COVID-19 pandemic, standardized testing scores were once again made a mandatory part of admissions, beginning with applications for the fall 2025 semester. Jay Hartzell commented that

21412-605: The first Black attendees. In an interview with a reporter he announced his desire to try-out for the football team. The Ford Crisis would begin and all Black admissions at the time were rescinded until policy could be drawn up. In the fall of 1956, the first Black students entered the university's undergraduate class. Black students were permitted to live in campus dorms, but were barred from campus cafeterias. The University of Texas integrated its facilities and desegregated its dormitories in 1965. UT, which had had an open admissions policy, adopted standardized testing for admissions in

21614-469: The first EVA and the rest break that followed, scientists in Houston combined two of the traverses into one that Conrad and Bean could follow from their landing point. The resultant traverse resembled a rough circle, and when the astronauts emerged from the LM some 13 hours after ending the first EVA, the first stop was Head crater , some 100 yards (91 m) from the LM. There, Bean noticed that Conrad's footprints showed lighter material underneath, indicating

21816-529: The first color television camera taken by an Apollo mission to the lunar surface, but transmission was lost after Bean accidentally pointed the camera at the Sun and its sensor was burned out. On the second of two moonwalks, they visited Surveyor 3 and removed parts for return to Earth. Lunar Module Intrepid lifted off from the Moon on November 20 and docked with the command module, which subsequently traveled back to Earth. The Apollo 12 mission ended on November 24 with

22018-420: The first day of flight to check its status, earlier than planned. They found no issues. At 30:52.44.36, the only necessary midcourse correction during the translunar coast was made, placing the craft on a hybrid, non-free-return trajectory. Previous crewed missions to lunar orbit had taken a free-return trajectory , allowing an easy return to Earth if the craft's engines did not fire to enter lunar orbit. Apollo 12

22220-456: The first human landing in July 1969, after which he returned to Air Force duty. Charles Fishman, in One Giant Leap , estimated the number of people and organizations involved into the Apollo program as "410,000 men and women at some 20,000 different companies contributed to the effort". Once Kennedy had defined a goal, the Apollo mission planners were faced with the challenge of designing

22422-474: The first lunar landing had Apollo 11 failed, but after the success of Neil Armstrong 's mission, Apollo 12 was postponed by two months, and other Apollo missions also put on a more relaxed schedule. More time was allotted for geologic training in preparation for Apollo 12 than for Apollo 11, Conrad and Bean making several geology field trips in preparation for their mission. Apollo 12's spacecraft and launch vehicle were almost identical to Apollo 11's. One addition

22624-441: The first men on the Moon in 1969. It was first conceived in 1960 during President Dwight D. Eisenhower's administration as a three-person spacecraft to follow the one-person Project Mercury , which put the first Americans in space. Apollo was later dedicated to President John F. Kennedy 's national goal for the 1960s of "landing a man on the Moon and returning him safely to the Earth" in an address to Congress on May 25, 1961. It

22826-477: The first person to fly in space, reinforcing American fears about being left behind in a technological competition with the Soviet Union. At a meeting of the US House Committee on Science and Astronautics one day after Gagarin's flight, many congressmen pledged their support for a crash program aimed at ensuring that America would catch up. Kennedy was circumspect in his response to the news, refusing to make

23028-421: The first stage live, carrying dummy upper stages filled with water. The first flight with a live S-IV was launched from LC-37. This was followed by five launches of boilerplate CSMs (designated AS-101 through AS-105 ) into orbit in 1964 and 1965. The last three of these further supported the Apollo program by also carrying Pegasus satellites, which verified the safety of the translunar environment by measuring

23230-423: The first time a current U.S. president had witnessed a crewed space launch, as well as Vice President Spiro Agnew , Apollo 12 launched as planned at 11:22:00 on November 14, 1969 (16:22:00 UT) from Kennedy Space Center. This was at the start of a launch window of three hours and four minutes to reach the Moon with optimal lighting conditions at the planned landing point. There were completely overcast rainy skies, and

23432-445: The frequency and severity of micrometeorite impacts. In September 1962, NASA planned to launch four crewed CSM flights on the Saturn I from late 1965 through 1966, concurrent with Project Gemini. The 22,500-pound (10,200 kg) payload capacity would have severely limited the systems which could be included, so the decision was made in October 1963 to use the uprated Saturn IB for all crewed Earth orbital flights. The Saturn IB

23634-498: The heavy lift-class Saturn launch vehicles , which would be required for Apollo. It became clear that managing the Apollo program would exceed the capabilities of Robert R. Gilruth 's Space Task Group , which had been directing the nation's crewed space program from NASA's Langley Research Center . So Gilruth was given authority to grow his organization into a new NASA center, the Manned Spacecraft Center (MSC). A site

23836-485: The important weight reductions that were offered by the LOR approach. Throughout 1960 and 1961, Houbolt campaigned for the recognition of LOR as a viable and practical option. Bypassing the NASA hierarchy, he sent a series of memos and reports on the issue to Associate Administrator Robert Seamans; while acknowledging that he spoke "somewhat as a voice in the wilderness", Houbolt pleaded that LOR should not be discounted in studies of

24038-492: The initial design should be continued as Block I which would be used for early testing, while Block II, the actual lunar spacecraft, would incorporate the docking equipment and take advantage of the lessons learned in Block I development. The Apollo Lunar Module (LM) was designed to descend from lunar orbit to land two astronauts on the Moon and take them back to orbit to rendezvous with the command module. Not designed to fly through

24240-518: The lack of tracking data confirming this caused it to conclude it most likely burned up in the atmosphere at the time of CM re-entry. The S-IVB is in a solar orbit that is sometimes affected by the Earth. Apollo program The Apollo program , also known as Project Apollo , was the United States human spaceflight program carried out by the National Aeronautics and Space Administration (NASA), which succeeded in preparing and landing

24442-518: The launch vehicle, with the spacecraft atop it, was rolled out to Launch Complex 39A on September 8, 1969. The training schedule was complete, as planned, by November 1, 1969; activities after that date were intended as refreshers. The crew members felt that the training, for the most part, was adequate preparation for the Moon mission. There were no significant changes to the Saturn V launch vehicle used on Apollo 12, SA–507, from that used on Apollo 11. There were another 17 instrumentation measurements in

24644-684: The legislature appropriated $ 1.35 million for the purchase of land next to the main campus. However, expansion was hampered by the restriction against using state revenues to fund construction of university buildings as set forth in Article 7, Section 14 of the Constitution. With the completion of Santa Rita No. 1 well and the discovery of oil on university-owned lands in 1923, the university added significantly to its Permanent University Fund. The additional income from Permanent University Fund investments allowed for bond issues in 1931 and 1947, which allowed

24846-645: The legislature to address funding for the university along with the Agricultural and Mechanical College (now known as Texas A&M University ). With sufficient funds to finance construction on both campuses, on April 8, 1931, the Forty Second Legislature passed H.B. 368. which dedicated the Agricultural and Mechanical College a 1/3 interest in the Available University Fund, the annual income from Permanent University Fund investments. In 1929,

25048-450: The long-range exploration of space; and none will be so difficult or expensive to accomplish. At the time of Kennedy's proposal, only one American had flown in space—less than a month earlier—and NASA had not yet sent an astronaut into orbit. Even some NASA employees doubted whether Kennedy's ambitious goal could be met. By 1963, Kennedy even came close to agreeing to a joint US-USSR Moon mission, to eliminate duplication of effort. With

25250-510: The lunar flights. On the extended lunar missions, an orbital scientific instrument package was carried. The service module was discarded just before reentry. The module was 24.6 feet (7.5 m) long and 12.83 feet (3.91 m) in diameter. The initial lunar flight version weighed approximately 51,300 pounds (23,300 kg) fully fueled, while a later version designed to carry a lunar orbit scientific instrument package weighed just over 54,000 pounds (24,000 kg). North American Aviation won

25452-403: The lunar surface his first words were "Whoopie! Man, that may have been a small one for Neil, but that's a long one for me." This was not an off-the-cuff remark: Conrad had made a US$ 500 bet with reporter Oriana Fallaci he would say these words, after she had queried whether NASA had instructed Neil Armstrong what to say as he stepped onto the Moon. Conrad later said he was never able to collect

25654-735: The mandate to establish "The University of Texas" by popular vote. On March 30, 1881, the Texas legislature organized the structure of the university and called for a popular vote to determine its location. Austin was chosen as the site with 30,913 votes, while Galveston was designated for the medical department. On November 17, 1882, the cornerstone of the Old Main building was laid at the original "College Hill" location, and University President Ashbel Smith expressed optimism about Texas's untapped resources. The University of Texas officially opened its doors on September 15, 1883. The old Main Building of

25856-408: The media. There was ample time for rest on the way back to Earth. One event was the photography of a solar eclipse that occurred when the Earth came between the spacecraft and the Sun; Bean described it as the most spectacular sight of the mission. Yankee Clipper returned to Earth on November 24, 1969, at 20:58 UT (3:58   pm Eastern Time, 10:58   am HST ), in the Pacific Ocean. The landing

26058-454: The mid-1950s, at least in part as a conscious strategy to minimize the number of Black undergraduates, given that they were no longer able to simply bar their entry after the Brown decision Following growth in enrollment after World War II, the university unveiled an ambitious master plan in 1960 designed for "10 years of growth" that was intended to "boost the University of Texas into the ranks of

26260-423: The middle 50% ranged from 26 to 31. In terms of class rank, 74.4% of enrolled freshmen were in the top 10% of their high school classes and 91.7% ranked in the top quarter. For fall 2019, 53,525 undergraduate students applied, 17,029 undergraduate students were admitted, and 8,170 undergraduate students enrolled in the university full or part time, making the acceptance rate 31.8% and enrollment rate 48% overall. In

26462-415: The mission commander. Usually low in seniority, they assembled the mission's rules, flight plan , and checklists, and kept them updated; For Apollo 12, they were Gerald P. Carr , Edward G. Gibson and Paul J. Weitz . Flight directors were Gerry Griffin , first shift, Pete Frank , second shift, Clifford E. Charlesworth , third shift, and Milton Windler , fourth shift. Flight directors during Apollo had

26664-454: The mission flew, had graduated from the University of Texas in 1955 with a degree in aeronautical engineering. Also a naval aviator, he was selected alongside Gordon in 1963, and first flew in space on Apollo 12. The three Apollo 12 crew members had backed up Apollo 9 earlier in 1969. The Apollo 12 backup crew was David R. Scott as commander, Alfred M. Worden as Command Module pilot, and James B. Irwin as Lunar Module pilot. They became

26866-452: The mission was delayed, and the sun would have risen too high in the sky at the original site for desired lighting conditions. The need for three days to recycle if a launch had to be scrubbed meant that only three of the five suitable sites found were designated as potential landing sites for Apollo 11, of which the Apollo 11 landing site in the Sea of Tranquility was the easternmost. Since Apollo 12

27068-460: The mission, a total exceeding 1,000 hours per crew member. Conrad and Bean received more mission-specific training than Apollo 11's Neil Armstrong and Buzz Aldrin had. This was in addition to the 1,500 hours of training they received as backup crew members for Apollo 9. The Apollo 12 training included over 400 hours per crew member in simulators of the Command Module (CM) and of the LM. Some of

27270-513: The money. To improve the quality of television pictures from the Moon, a color camera was carried on Apollo 12 (unlike the monochrome camera on Apollo 11). When Bean carried the camera to the place near the LM where it was to be set up, he inadvertently pointed it directly into the Sun, destroying the Secondary Electron Conduction (SEC) tube . Television coverage of this mission was thus terminated almost immediately. After raising

27472-454: The nation, behind only Georgia Tech . A 2013 College Database study found that UT Austin was 22nd in the nation in terms of increased lifetime earnings by graduates. UT Austin is classified among "R1: Doctoral Universities – Very high research activity." For the 2014–2015 cycle, the university was awarded over $ 580 million in sponsored projects, and has earned more than 300 patents since 2003. The University of Texas at Austin houses

27674-516: The observation deck in the tower of the Main Building. Armed with multiple firearms, he killed 14 people on campus, 11 from the observation deck and below the clocks on the tower, and three more in the tower, as well as wounding two others inside the observation deck. The massacre ended when Whitman was shot and killed by police after they breached the tower. After the Whitman event, the observation deck

27876-460: The presence of ejecta from Copernicus crater , 230 miles (370 km) to the north, something that scientists examining overhead photographs of the site had hoped to find. After the mission, samples from Head allowed geologists to date the impact that formed Copernicus—according to initial dating, some 810,000,000 years ago. The astronauts proceeded to Bench crater and Sharp crater and past Halo crater before arriving at Surveyor crater , where

28078-478: The press, during a presentation by von Braun. Webb jumped in and defended von Braun, until Kennedy ended the squabble by stating that the matter was "still subject to final review". Webb held firm and issued a request for proposal to candidate Lunar Excursion Module (LEM) contractors. Wiesner finally relented, unwilling to settle the dispute once and for all in Kennedy's office, because of the President's involvement with

28280-535: The prime contractors of the respective modules. George Glacken, a flight test engineer at North American Aviation , builder of the CSM, proposed Yankee Clipper as such ships had "majestically sailed the high seas with pride and prestige for a new America". Intrepid was from a suggestion by Robert Lambert, a planner at Grumman , builder of the LM, as evocative of "this nation's resolute determination for continued exploration of space, stressing our astronauts' fortitude and endurance of hardship". The differences between

28482-540: The project was overseen by Thomas J. Kelly . Before the Apollo program began, Wernher von Braun and his team of rocket engineers had started work on plans for very large launch vehicles, the Saturn series , and the even larger Nova series. In the midst of these plans, von Braun was transferred from the Army to NASA and was made Director of the Marshall Space Flight Center. The initial direct ascent plan to send

28684-519: The question. Seamans's establishment of an ad hoc committee headed by his special technical assistant Nicholas E. Golovin in July 1961, to recommend a launch vehicle to be used in the Apollo program, represented a turning point in NASA's mission mode decision. This committee recognized that the chosen mode was an important part of the launch vehicle choice, and recommended in favor of a hybrid EOR-LOR mode. Its consideration of LOR—as well as Houbolt's ceaseless work—played an important role in publicizing

28886-483: The region, and First Amendment advocacy groups, including an official statement from the UT Faculty Council Executive Committee denouncing it, in part due to the extreme, chaotic, and violent police response that ensued and alleged violations of First Amendment rights. The university additionally set new rules for protests on campus, such as banning masks and face coverings and instituting

29088-501: The region. Relative to other universities in the state of Texas, UT Austin was second to Rice University in selectivity according to a Business Journal study weighing acceptance rates and the mid-range of the SAT and ACT. The University of Texas at Austin was ranked as the 18th most selective in the South. As a state public university, UT Austin was subject to Texas House Bill 588 , which guaranteed Texas high school seniors graduating in

29290-407: The sandblasting removed more dust than it delivered onto the Surveyor, because the probe was covered by a thin layer that gave it a tan hue as observed by the astronauts, and every portion of the surface exposed to the direct sandblasting was lightened back toward the original white color through the removal of lunar dust. When Conrad, the shortest man of the initial groups of astronauts, stepped onto

29492-426: The school 5th among all business schools and first among public business schools for the largest number of alumni who are S&P 500 CEOs. Similarly, a 2005 USA Today report ranked the university as "the number one source of new Fortune 1000 CEOs". A "payback" analysis published by SmartMoney in 2011 comparing graduates' salaries to tuition costs concluded the school was the second-best value of all colleges in

29694-550: The school has claimed more titles in men's and women's sports than any other member in the Big 12 . As of 2020, 13 Nobel Prize winners, 25 Pulitzer Prize winners, three Turing Award winners, two Fields Medal recipients, two Wolf Prize winners, and three Abel Prize winners have been affiliated with the school as alumni, faculty members, or researchers. The university has also been affiliated with three Primetime Emmy Award winners, and as of 2021, its students and alumni have earned

29896-501: The simulations were linked in real time to flight controllers in Mission Control. To practice landing on the Moon, Conrad flew the Lunar Landing Training Vehicle (LLTV), training in which continued to be authorized even though Armstrong had been forced to bail out of a similar vehicle in 1968, just before it crashed. Soon after being assigned as Apollo 12 crew commander, Conrad met with NASA geologists and told them that

30098-450: The sixth floor, before killing himself. No one else was injured, except for one sprained ankle suffered by a female student fleeing the scene. In early 2020, following a major outbreak of the new coronavirus , the university restricted travel to Wuhan province in China, aligning with the U.S. Department of State's recommendation. By March 17, 2020, then-UT President Gregory L. Fenves announced

30300-436: The solar wind, would be deployed and then brought back to Earth by the astronauts. A Dust Detector was used to measure the accumulation of lunar dust on the equipment. Apollo 12's Passive Seismic Experiment (PSE), a seismometer, would measure moonquakes and other movements in the Moon's crust, and would be calibrated by the nearby planned impact of the ascent stage of Apollo 12's LM, an object of known mass and velocity hitting

30502-492: The southeast, in hopes of using the land to relocate the university's intramural fields, baseball field, tennis courts, and parking lots. On March 6, 1967, the Sixtieth Texas Legislature changed the university's official name from "The University of Texas" to "The University of Texas at Austin" to reflect the growth of the University of Texas System . On August 1, 1966, Texas student Charles Whitman barricaded

30704-400: The space station, cislunar, and lunar landing missions. Once Kennedy's Moon landing goal became official, detailed design began of a command and service module (CSM) in which the crew would spend the entire direct-ascent mission and lift off from the lunar surface for the return trip, after being soft-landed by a larger landing propulsion module. The final choice of lunar orbit rendezvous changed

30906-448: The specification for another competition for spacecraft procurement bids in October 1961. On November 28, 1961, it was announced that North American Aviation had won the contract, although its bid was not rated as good as the Martin proposal. Webb, Dryden and Robert Seamans chose it in preference due to North American's longer association with NASA and its predecessor . Landing humans on

31108-805: The student organization that organized the protests, the Palestine Solidarity Committee. Travis County Attorney Delia Garza stated that the way that the university handled the protests put a strain on the local criminal justice system, specifically reprimanding the sending of protestors to jail for low-level charges. A report later released by the UT Austin Committee of Counsel on Academic Freedom and Responsibility (CCAFR) on July 17, 2024 found that UT Austin administrators violated its own institutional rules in clear disregard of freedom of speech and expression protections. The university's property totals 1,438.5 acres (582.1 ha), comprising

31310-419: The successful return of Apollo 11 in July 1969, more time was allotted for geology, but the astronauts' focus was on getting time in the simulators without being pre-empted by the Apollo 11 crew. On the six Apollo 12 geology field trips, the astronauts would practice as if on the Moon, collecting samples and documenting them with photographs, while communicating with a CAPCOM and geologists who were out of sight in

31512-492: The surface, including of candidate sites for future Apollo landings. A second plane change maneuver was made at 159:04:45.47, lasting 19.25 seconds. The trans-Earth injection burn, to send the CSM Yankee Clipper towards home, was conducted at 172:27:16.81 and lasted 130.32 seconds. Two short midcourse correction burns were made en route. A final television broadcast was made, the astronauts answering questions submitted by

31714-478: The swimmers recovering the CM would not have to attach an auxiliary loop. LM changes included a structural modification so that scientific experiment packages could be carried for deployment on the lunar surface. Two hammocks were added for greater comfort of the astronauts while resting on the Moon, and a color television camera substituted for the black and white one used on the lunar surface during Apollo 11. The Apollo Lunar Surface Experiments Package , or ALSEP,

31916-427: The technical details of the space program, and was put off by the massive financial commitment required by a crewed Moon landing. When Kennedy's newly appointed NASA Administrator James E. Webb requested a 30 percent budget increase for his agency, Kennedy supported an acceleration of NASA's large booster program but deferred a decision on the broader issue. On April 12, 1961, Soviet cosmonaut Yuri Gagarin became

32118-561: The telemetry failure pattern from an earlier test when a power loss caused a malfunction in the CSM signal conditioning electronics (SCE), which converted raw signals from instrumentation to data that could be displayed on Mission Control's consoles, and knew how to fix it. Aaron made a call, "Flight, EECOM. Try SCE to Aux", to switch the SCE to a backup power supply. The switch was fairly obscure, and neither Flight Director Gerald Griffin, CAPCOM Gerald P. Carr, nor Conrad knew what it was; Bean, who as LMP

32320-477: The third lunar orbit, there was another burn to circularize the craft's orbit to 66.1 by 54.59 nautical miles (122.4 by 101.1 km; 76.07 by 62.82 mi), and on the next revolution, preparations began for the lunar landing. The CSM and LM undocked at 107:54:02.3; a half hour later there was a burn by the CSM to separate them. The 14.4 second burn by some of the CSM's thrusters meant that the two craft would be 2.2 nautical miles (4.1 km; 2.5 mi) apart when

32522-489: The threats from the Republican -led State Legislature and the University of Texas System Board of Regents, and to restore "confidence" in the university, reacting to changing tides in public opinion towards higher education amongst Republicans. The university's Division of Campus and Community Engagement operated the University of Texas-University Charter School , a charter school system with 23 campuses across Texas, until

32724-925: The three-person Apollo command and service module directly to the lunar surface, on top of a large descent rocket stage, would require a Nova-class launcher, with a lunar payload capability of over 180,000 pounds (82,000 kg). The June 11, 1962, decision to use lunar orbit rendezvous enabled the Saturn V to replace the Nova, and the MSFC proceeded to develop the Saturn rocket family for Apollo. Since Apollo, like Mercury, used more than one launch vehicle for space missions, NASA used spacecraft-launch vehicle combination series numbers: AS-10x for Saturn I, AS-20x for Saturn IB, and AS-50x for Saturn V (compare Mercury-Redstone 3 , Mercury-Atlas 6 ) to designate and plan all missions, rather than numbering them sequentially as in Project Gemini. This

32926-402: The time of Apollo 12, also became a naval aviator in 1953, following graduation from the University of Washington with a degree in chemistry, and completed test pilot school at Patuxent River. Selected as a Group 3 astronaut in 1963, he flew with Conrad on Gemini 11. The original Lunar Module pilot assigned to work with Conrad was Clifton C. Williams Jr. , who was killed in October 1967 when

33128-410: The top 10% of their class admission to any public Texas university. A new state law granting UT Austin (but no other state university) a partial exemption from the top 10% rule, Senate Bill 175, was passed by the 81st Legislature in 2009. It modified this admissions policy by limiting automatically admitted freshmen to 75% of the entering in-state freshman class, starting in 2011. The university will admit

33330-517: The top one percent, the top two percent and so forth until the cap is reached; the university currently admits the top 6 percent. Furthermore, students admitted under Texas House Bill 588 are not guaranteed their choice of college or major, but rather only guaranteed admission to the university as a whole. Many colleges, such as the Cockrell School of Engineering, have secondary requirements that must be met for admission. For others who go through

33532-577: The top state universities in the nation." In 1965, the Texas Legislature granted the university Board of Regents to use eminent domain to purchase additional properties surrounding the original 40 acres (160,000 m ). The university began buying parcels of land to the north, south, and east of the existing campus, particularly in the Blackland neighborhood to the east and the Brackenridge tract to

33734-582: The traditional application process, selectivity is deemed "more selective" according to the Carnegie Foundation for the Advancement of Teaching and by U.S. News & World Report . For fall 2017, 51,033 applied and 18,620 were accepted (36.5%), and of those accepted, 45.2% enrolled. Among freshman students who enrolled in fall 2017, SAT scores for the middle 50% ranged from 570 to 690 for critical reading and 600–710 for math. ACT composite scores for

33936-426: The training for lunar surface activities would be conducted much as Apollo 11's, but there was to be no publicity or involvement by the media. Conrad felt he had been abused by the press during Gemini, and the sole Apollo 11 geology field trip had turned into a near-fiasco, with a large media contingent present, some getting in the way—the astronauts had trouble hearing each other due to a hovering press helicopter. After

34138-465: The university broke ground on the $ 120 million Bill & Melinda Gates Computer Science Complex and Dell Computer Science Hall and the $ 51 million Belo Center for New Media, both of which are now complete. The new LEED gold-certified, 110,000-square-foot (10,000 m ) Student Activity Center (SAC) opened in January 2011, housing study rooms, lounges and food vendors. The SAC was constructed as

34340-489: The university has generated its own electricity. Today its natural gas cogeneration plant has a capacity of 123 MW. The university also operates a TRIGA nuclear reactor at the J. J. Pickle Research Campus . The university continues to expand its facilities on campus. In 2010, the university opened the state-of-the-art Norman Hackerman building (on the site of the former Experimental Sciences Building) housing chemistry and biology research and teaching laboratories. In 2010,

34542-419: The university was built in a Victorian - Gothic style and served as the central point of the campus's 40-acre (16 ha) site, and was used for nearly all purposes. But by the 1930s, discussions arose about the need for new library space, and the Main Building was razed in 1934, despite the objections of many students and faculty. The modern-day tower and Main Building were constructed in its place. In 1916,

34744-534: The university's Harry Ransom Humanities Research Center include one of only 21 remaining complete copies of the Gutenberg Bible and the first permanent photograph, View from the Window at Le Gras , taken by Nicéphore Niépce . The newest museum, the 155,000-square-foot (14,400 m ) Blanton Museum of Art , is the largest university art museum in the United States and hosts approximately 17,000 works from Europe,

34946-585: The university, under the explicit direction of President Hartzell, requested the assistance of the Austin Police Department (APD) and the Texas Department of Public Safety (DPS) , in coordination with Texas Governor Greg Abbott , in an attempt to quell said protests and an "occupation" of the university, in contrast to free speech on campus laws praised by Abbott and the university in prior years. The deployment of multiple police units led to

35148-508: The university. Also in 2008, Darrell K Royal-Texas Memorial Stadium was expanded to a seating capacity of 100,119, making it the largest stadium (by capacity) in the state of Texas at the time. On Tuesday, September 28, 2010, a shooting occurred at the Perry–Castañeda Library (PCL) where student Colton Tooley, armed with an AK-47, fired shots on his walk from Guadalupe Street to the library's front entrance. The student ascended to

35350-410: The usual pealing of Westminster Quarters every quarter-hour between 6 a.m. and 9 p.m. In 1998, after the installation of security and safety measures, the observation deck reopened to the public indefinitely for weekend tours. The university's seven museums and seventeen libraries hold over nine million volumes, making it the seventh-largest academic library in the country. The holdings of

35552-474: The vehicle encountered winds of 151.7 knots (280.9 km/h; 174.6 mph) during ascent, the strongest of any Apollo mission. There was a NASA rule against launching into a cumulonimbus cloud ; this had been waived and it was later determined that the launch vehicle never entered such a cloud. Had the mission been postponed, it could have been launched on November 16 with landing at a backup site where there would be no Surveyor, but since time pressure to achieve

35754-430: The workability of the approach. In late 1961 and early 1962, members of the Manned Spacecraft Center began to come around to support LOR, including the newly hired deputy director of the Office of Manned Space Flight, Joseph Shea , who became a champion of LOR. The engineers at Marshall Space Flight Center (MSFC), who were heavily invested in direct ascent, took longer to become convinced of its merits, but their conversion

35956-509: The world by Academic Ranking of World Universities (ARWU) in 2024, 52nd worldwide by Times Higher Education World University Rankings (2024), and 66th globally by QS World University Rankings (2024). UT Austin was also ranked 35th in the world by the Center for World University Rankings (CWUR) in 2024. The University of Texas at Austin is considered to be a " Public Ivy "—a public university that provides an Ivy League collegiate experience at

36158-478: Was 11.42 feet (3.48 m) tall, 12.83 feet (3.91 m) in diameter, and weighed approximately 12,250 pounds (5,560 kg). A cylindrical service module (SM) supported the command module, with a service propulsion engine and an RCS with propellants, and a fuel cell power generation system with liquid hydrogen and liquid oxygen reactants. A high-gain S-band antenna was used for long-distance communications on

36360-408: Was a suite of scientific instruments designed to be emplaced on the lunar surface by the Apollo astronauts, and thereafter operate autonomously, sending data to Earth. Development of the ALSEP was part of NASA's response to some scientists who opposed the crewed lunar landing program (they felt that robotic craft could explore the Moon more cheaply) by demonstrating that some tasks, such as deployment of

36562-555: Was an upgraded version of the Saturn I. The S-IB first stage increased the thrust to 1,600,000 pounds-force (7,120 kN) by uprating the H-1 engine. The second stage replaced the S-IV with the S-IVB-200 , powered by a single J-2 engine burning liquid hydrogen fuel with LOX, to produce 200,000 pounds-force (890  kN ) of thrust. A restartable version of the S-IVB was used as the third stage of

36764-497: Was announced by Wernher von Braun at a briefing on June 7, 1962. But even after NASA reached internal agreement, it was far from smooth sailing. Kennedy's science advisor Jerome Wiesner , who had expressed his opposition to human spaceflight to Kennedy before the President took office, and had opposed the decision to land people on the Moon, hired Golovin, who had left NASA, to chair his own "Space Vehicle Panel", ostensibly to monitor, but actually to second-guess NASA's decisions on

36966-593: Was changed by the time human flights began. Since Apollo, like Mercury, would require a launch escape system (LES) in case of a launch failure, a relatively small rocket was required for qualification flight testing of this system. A rocket bigger than the Little Joe used by Mercury would be required, so the Little Joe II was built by General Dynamics / Convair . After an August 1963 qualification test flight , four LES test flights ( A-001 through 004 ) were made at

37168-536: Was chosen in Houston , Texas, on land donated by Rice University , and Administrator Webb announced the conversion on September 19, 1961. It was also clear NASA would soon outgrow its practice of controlling missions from its Cape Canaveral Air Force Station launch facilities in Florida, so a new Mission Control Center would be included in the MSC. In September 1962, by which time two Project Mercury astronauts had orbited

37370-528: Was closed until 1968 and then closed again in 1975 following a series of suicide jumps during the 1970s. In 1999, after installation of security fencing and other safety precautions, the tower observation deck reopened to the public. There is a turtle pond park near the tower dedicated to those affected by the tragedy. The first presidential library on a university campus was dedicated on May 22, 1971, with former President Johnson , Lady Bird Johnson and then-President Richard Nixon in attendance. Constructed on

37572-471: Was designed by the crew with the aid of several employees of NASA contractors. The Apollo 12 landing area on the Moon is within the portion of the lunar surface shown on the insignia, based on a photograph of a globe of the Moon, taken by engineers. The clipper ship was based on photographs of such a ship obtained by Bean. After the mission, Conrad urged his crewmates to join him in the Skylab program, seeing in it

37774-414: Was discovered by amateur astronomer Bill Yeung who gave it the temporary designation J002E3 before it was determined to be an artificial object. Again in solar orbit as of 2021, it may again be captured by Earth's gravity, but not at least until the 2040s. The S-IVBs used on later lunar missions were deliberately crashed into the Moon to create seismic events that would register on the seismometers left on

37976-669: Was displayed at the Paris Air Show and was then placed at NASA's Langley Research Center in Hampton, Virginia ; ownership was transferred to the Smithsonian in July 1971. It is on display at the Virginia Air and Space Center in Hampton. Mission Control had remotely fired the service module's thrusters after jettison, hoping to have it skip off the atmosphere and enter a high-apogee orbit, but

38178-506: Was feared that the lightning strike could have damaged the explosive bolts that opened the Command Module's parachute compartment. The decision was made not to share this with the astronauts and to continue with the flight plan, since they would die if the parachutes failed to deploy, whether following an Earth-orbit abort or upon a return from the Moon, so nothing was to be gained by aborting. The parachutes deployed and functioned normally at

38380-466: Was hammocks to allow Conrad and Bean to rest more comfortably on the Moon. Shortly after being launched on a rainy day at Kennedy Space Center, Apollo 12 was twice struck by lightning , causing instrumentation problems but little damage. The crew found that switching to the auxiliary power supply resolved the data relay problem, which helped save the mission. The outward journey to the Moon otherwise saw few problems. On November 19, Conrad and Bean achieved

38582-713: Was hard, resulting in a camera becoming dislodged and striking Bean in the forehead. After recovery by USS  Hornet , they entered the Mobile Quarantine Facility (MQF), while lunar samples and Surveyor parts were sent ahead by air to the Lunar Receiving Laboratory (LRL) in Houston. Once the Hornet docked in Hawaii, the MQF was offloaded and flown to Ellington Air Force Base near Houston on November 29, from where it

38784-477: Was named after Apollo , the Greek god of light, music, and the Sun, by NASA manager Abe Silverstein , who later said, "I was naming the spacecraft like I'd name my baby." Silverstein chose the name at home one evening, early in 1960, because he felt "Apollo riding his chariot across the Sun was appropriate to the grand scale of the proposed program". The context of this was that the program focused at its beginning mainly on developing an advanced crewed spacecraft,

38986-422: Was not a major factor: they had to be close to the lunar equator and not on the periphery of the portion of the lunar surface visible from Earth; they had to be relatively flat and without major obstructions along the path the Lunar Module (LM) would fly to reach them, their suitability confirmed by photographs from Lunar Orbiter probes. Also desirable was the presence of another suitable site further west in case

39188-424: Was taken to the LRL, where the astronauts remained until released from quarantine on December 10. The Apollo 12 mission patch shows the crew's naval background; all three astronauts at the time of the mission were U.S. Navy commanders . It features a clipper ship arriving at the Moon, representing the CM Yankee Clipper . The ship trails fire, and flies the flag of the United States. The mission name APOLLO XII and

39390-414: Was targeted for an ellipse-shaped landing zone, rather than at a specific point, there was no planning for geology traverses, the designated tasks to be done at sites of the crew's choosing. For Apollo 12, before the mission, some of NASA's geology team met with the crew and Conrad suggested they lay out possible routes for him and Bean. The result was four traverses, based on four potential landing points for

39592-662: Was the first crewed spacecraft to orbit another celestial body, and Apollo 11 was the first crewed spacecraft to land humans on one. Overall, the Apollo program returned 842 pounds (382 kg) of lunar rocks and soil to Earth, greatly contributing to the understanding of the Moon's composition and geological history. The program laid the foundation for NASA's subsequent human spaceflight capability and funded construction of its Johnson Space Center and Kennedy Space Center . Apollo also spurred advances in many areas of technology incidental to rocketry and human spaceflight, including avionics , telecommunications, and computers. The program

39794-405: Was the first crewed spacecraft to take a hybrid free-return trajectory, that would require another burn to return to Earth, but one that could be executed by the LM's Descent Propulsion System (DPS) if the SPS failed. The use of a hybrid trajectory allowed more flexibility in mission planning. It for example allowed Apollo 12 to launch in daylight and reach the planned landing spot on schedule. Use of

39996-403: Was the only component of the Apollo spacecraft to survive without major configuration changes as the program evolved from the early Apollo study designs. Its exterior was covered with an ablative heat shield , and had its own reaction control system (RCS) engines to control its attitude and steer its atmospheric entry path. Parachutes were carried to slow its descent to splashdown. The module

40198-444: Was the spacecraft's engineer, knew where to find it and threw the switch, after which the telemetry came back online, revealing no significant malfunctions. Bean put the fuel cells back online, and the mission continued. Once in Earth parking orbit , the crew carefully checked out their spacecraft before re-igniting the S-IVB third stage for trans-lunar injection . The lightning strikes caused no serious permanent damage. Initially, it

40400-423: Was the third US human spaceflight program to fly, preceded by the two-person Project Gemini conceived in 1961 to extend spaceflight capability in support of Apollo. Kennedy's goal was accomplished on the Apollo 11 mission when astronauts Neil Armstrong and Buzz Aldrin landed their Apollo Lunar Module (LM) on July 20, 1969, and walked on the lunar surface, while Michael Collins remained in lunar orbit in

40602-421: Was to attempt the first lunar landing if Apollo 11 failed, both sets of astronauts trained for the same sites. With the success of Apollo 11, it was initially contemplated that Apollo 12 would land at the site next further west from the Sea of Tranquility, in Sinus Medii . However, NASA planning coordinator Jack Sevier and engineers at the Manned Spaceflight Center at Houston argued for a landing close enough to

40804-422: Was upgraded to 7,610,000 pounds-force (33,900 kN). The second and third stages burned liquid hydrogen; the third stage was a modified version of the S-IVB, with thrust increased to 230,000 pounds-force (1,020 kN) and capability to restart the engine for translunar injection after reaching a parking orbit .
