72-451: STS-1 ( Space Transportation System -1) was the first orbital spaceflight of NASA 's Space Shuttle program . The first orbiter , Columbia , launched on April 12, 1981, and returned on April 14, 1981, 54.5 hours later, having orbited the Earth 37 times. Columbia carried a crew of two—commander John W. Young and pilot Robert L. Crippen . It was the first American crewed space flight since

144-537: A Ku-band antenna for use with the Tracking and Data Relay Satellite (TDRS). The mission's original launch date of October 29, 1983, was scrubbed due to concerns with the exhaust nozzle on the right solid rocket booster (SRB). For the first time in the history of the shuttle program, the shuttle stack was rolled back to the Vehicle Assembly Building (VAB), where it was destacked and the orbiter returned to

216-524: A heavy lift launch vehicle for the nuclear ferry and space station modules. A special " Mars Excursion Module " would be the only remaining vehicle necessary for a human Mars landing. The STS was championed by NASA Administrator Thomas O. Paine until May 1969 and gained Agnew's enthusiastic support. However, as Apollo accomplished its objective of landing the first humans on the Moon , Nixon realized that political support for further crewed space activities

288-635: A "heads down" attitude (to reduce loading on the wings). Simultaneously control was passed from the launch team in Florida to Flight Director Neil Hutchinson's Silver team in Flight Control Room 1 (FCR 1) in Texas with astronaut Dan Brandenstein as their CAPCOM. Columbia' s main engines were throttled down to 65% thrust to transit the region of Max Q , the point during ascent when the shuttle undergoes maximum aerodynamic stress. This occurred 56 seconds into

360-415: A "steam catapult shot" (such as when an aircraft is launched from an aircraft carrier). The stack's combined northwards translation and climb above the launch tower's lightning rod were readily apparent to Young. After clearing the tower the stack began a right roll (until the +Z axis or vertical fin pointed) to a launch azimuth of 067° True (in order to achieve an orbital inclination of 40.30°), and pitched to

432-465: A 246 × 248 km (153 × 154 mi) orbit. This subtle deviation from the original plan of 240 km (150 mi) circular went largely unnoticed. In fact, it adjusted the spacecraft's orbital period to take account of the April 10, 1981, scrub, so that attempts could still be made to use KH-11 reconnaissance satellites to image Columbia on orbit. Overall Young commented that there

504-604: A celebration of the anniversary; a technical problem had prevented STS-1 from launching two days earlier, as was planned. Commander John Young and pilot Robert Crippen were selected as the STS-1 crew in early 1978. Young stated that as the Chief of the Astronaut Office he recommended himself to command the mission. Young, with four previous missions, was the most experienced astronaut in NASA at

576-470: A childhood flashback shows that the character Lieutenant Colonel Cameron Mitchell witnessed the launch with his father live on television at the age of ten, one of the events that led to him becoming a United States Air Force pilot . NASA began a tradition of playing music to astronauts during the Project Gemini , and first used music to wake up a flight crew during Apollo 15 . A special musical track

648-699: A miscommunication during the operations were the cause of the accident. A report called LC-39A Mishap Investigation Board Final Report was released with the findings. The names of John Bjornstad, Forrest Cole and Nicholas Mullon are engraved on a monument at the US Space Walk of Fame in Florida. Space Transportation System In February 1969, President Richard Nixon appointed a Space Task Group headed by Vice President Spiro Agnew to recommend human space projects beyond Apollo. The group responded in September with

720-569: A need to undertake initial tests of the system prior to the first orbital flight. To that end, Vice President Walter F. Mondale as chairman of the National Space Council suggested a suborbital flight landing at the emergency landing site at Dakar, Senegal . NASA further suggested that STS-1, instead of being an orbital flight, be used to test the Return To Launch Site (RTLS) abort scenario . This involved an abort being called in

792-717: A permanent lunar base by 1981. NERVA rockets would be used for nuclear "tugs" designed to take payloads from Low Earth Orbit to larger orbits, resupply of several space stations in various orbits around the Earth and Moon , and support for a permanent lunar base. The NERVA rocket would also be used in the Saturn S-N, an upper stage for the Saturn V rocket' upgrading the Saturn's low Earth orbit (LEO) capability to 340,000 pounds (150 t). STS-9 STS-9 (also referred to Spacelab 1 )

864-457: A planned 280 km (174 mi) circular). These two firings were single engined utilizing the crossfeed system. The crew reported a cold first night on board despite acceptable temperature indications. They found the second night comfortable after settings were adjusted. During the second day of the mission, the astronauts received a phone call from Vice President George H. W. Bush . President Ronald Reagan had originally intended to visit

936-546: A rate exceeding its structural capability. Young then slowly pitched Columbia up to the wings level nose high entry attitude. Both crew members armed their ejection seats during this pitch around. Nearly half an hour later APU 1 was started as planned. Shortly afterwards, Columbia entered an approximately 21-minute long communications blackout. This was due to a combination of ionization (16 minutes) and lack of ground station coverage between Guam and Buckhorn Tracking Station at Dryden Flight Research Facility. Entry Interface (EI)

1008-465: Is chosen for each day in space, often by the astronauts' families, to have a special meaning to an individual member of the crew, or in reference to the day's planned activities. I think it is only right that we mention a couple of guys that gave their lives a few weeks ago in our countdown demonstration test: John Bjornstad and Forrest Cole. They believed in the space program, and it meant a lot to them. I am sure they would be thrilled to see where we have

1080-586: The Apollo–Soyuz Test Project (ASTP) in 1975. STS-1 was also the maiden test flight of a new American spacecraft to carry a crew, though it was preceded by atmospheric testing (ALT) of the orbiter and ground testing of the Space Shuttle system. The launch occurred on the 20th anniversary of Vostok 1 , the first human spaceflight, performed by Yuri Gagarin for the USSR . This was a coincidence rather than

1152-623: The Johnson Space Center (JSC) in Texas . Funding for Spacelab 1 was provided by the ESA. After Columbia's return from STS-5 in November 1982, it received several modifications and changes in preparation for STS-9. Most of these changes were intended to support the Spacelab module and crew, such as the addition of a tunnel connecting the Spacelab to the orbiter's airlock, and additional provisions for

1224-641: The Mission Control Center during the mission, but at the time was still recovering from an assassination attempt which had taken place two weeks before the launch (Reagan had only returned home to the White House the day prior to the launch). The crew awoke from their second sleep period earlier than planned. Preparations for return to Earth began with breakfast. Stowing of cabin items, flight control system checkout, data processing system reconfigurations, and then ejection suit donning followed. In Houston,

1296-454: The Moon and making him the most experienced space traveler to date. Young, who also commanded Columbia on its maiden voyage STS-1 , was the first person to fly the same space vehicle into orbit more than once. STS-9 marked the only time that two pre-Shuttle era astronaut veterans (Garriott and Young) would fly on the same Space Shuttle mission. STS-9 was also the first Space Shuttle mission to have more than one veteran astronaut. The mission

1368-512: The Orbiter Processing Facility (OPF) before launch – 610 days, the time needed for the replacement of many of its heat shield tiles . The NASA mission objective for the maiden flight was to accomplish a safe ascent into orbit and return to Earth for a safe landing of Orbiter and crew. The only payload carried on the mission was a Development Flight Instrumentation (DFI) package, which contained sensors and measuring devices to record

1440-523: The Orbiter Processing Facility (OPF), while the suspect booster underwent repairs. The shuttle was restacked and returned to the launch pad on November 8, 1983. The mission's main payload, Spacelab 1, is depicted in the payload bay of the Columbia . The nine stars and the path of the orbiter indicate the flight's numerical designation, STS-9. STS-9 launched successfully from Kennedy Space Center at 11:00:00 a.m. EST on November 28, 1983. The shuttle's crew

1512-553: The Shuttle Carrier Aircraft . The 36-orbit, 1,729,348 km (1,074,567 mi) flight lasted 2   days, 6   hours, 20   minutes and 53   seconds. STS-1 was the first orbital test flight of what NASA claims was, at the time, the most complex flying machine ever built. Roughly 70 anomalies were observed during and after the flight, owing to the many components and systems that could not otherwise be adequately tested. These included: Despite these problems,

1584-605: The first crewed space flight , when the orbiter Columbia lifted off from Pad A, Launch Complex 39 , at the Kennedy Space Center . The launch took place at 12:00:04   UTC . A launch attempt two days earlier was scrubbed because Columbia ' s four primary general purpose IBM System/4 Pi computers (GPCs) failed to provide correct timing to the backup flight system (BFS) when the GPCs were scheduled to transition from vehicle checkout to flight configuration mode. Not only

1656-512: The 1980s and 1990s, and was the first thing shown on the channel, along with footage of Neil Armstrong on the Moon and the launch of Apollo 11 . IMAX cameras filmed the launch, landing, and mission control during the flight, for a documentary film entitled Hail Columbia , which debuted in 1982 and later became available on DVD . The title of the film comes from the pre-1930s unofficial American national anthem, " Hail, Columbia ". The beginning of

1728-411: The 36th orbit over the southern Indian Ocean and changed the orbital parameters from 270 × 274 km (168 × 170 mi) to 270 × 0 km (168 × 0 mi). This ensured atmospheric capture of the spacecraft close enough to the planned landing site to have sufficient energy for a controlled glide landing, but not so close that energy would have to be dissipated at

1800-564: The BFS could also be affected by the same failure due to the soldering defect. If such a failure occurred, switching the vehicle back to normal flight control software on multiple GPCs from a single GPC running BFS takes a lot longer, in essence leaving the vehicle without any control at all during the change. Columbia landed on Runway 17 at Edwards Air Force Base on December 8, 1983, at 03:47:24 p.m. PST , having completed 167 orbits and travelled 4.3 million miles (6.9 million kilometres) over

1872-622: The Backup Flight Software, loss of vehicle and crew would have resulted". Post-flight analysis revealed the GPCs (General Purpose Computers) failed when the RCS thruster motion knocked a piece of solder loose and shorted out the CPU board. A GPC running BFS may or may not have the same soldering defect as the rest of the GPCs. Switching the vehicle to the BFS from normal flight control can happen relatively instantaneously, and that particular GPC running

1944-581: The Crimson team headed by their Flight Director Don Puddy came on duty in FCR   1 for the mission's final shift. His CAPCOM was astronaut Joseph P. Allen with Frederick Hauck assisting. Payload bay door closing was a critical milestone to ensure vehicle structural and thermal integrity for re-entry. If power closing had failed, Crippen was trained to conduct a one-man extravehicular activity (EVA) to manually winch them closed. With cabin switch positions verified,

2016-868: The OMS pods. This was televised to the ground. Shortly afterwards Young, then Crippen doffed their emergency ejection suits. The majority of the crew's approximately 53   hours in low Earth orbit was spent conducting systems tests. Despite the scheduling impact of efforts to image Columbia ' s TPS by utilizing external assets, these were all accomplished. They included: Crew Optical Alignment Sight (COAS) calibration, star tracker performance, Inertial Measurement Unit (IMU) performance, manual and automatic RCS testing, radiation measurement, propellant crossfeeding, hydraulics functioning, fuel cell purging, and photography. The OMS-3 and OMS-4 burns at 006:20:46 and 007:05:32 MET respectively raised this orbit to 273.9 × 274.1 km (170.2 × 170.3 mi) (compared to

2088-478: The STS-1 mission was completed successfully, and in most respects Columbia performed optimally. After some modifications to the Shuttle and to the launch and reentry procedures, Columbia flew the next four Shuttle missions. The artwork for the official mission insignia was designed by artist Robert McCall . It is a symbolic representation of the Space Shuttle. The image does not depict the black wing roots present on

2160-538: The Young-Crippen Firing Room. NASA described the mission as "the boldest test flight in history". STS-1 and STS-2 were the only two shuttle flights to have the External Tank painted white. To reduce the Shuttle's overall weight, all flights from STS-3 onward used an unpainted tank. The use of an unpainted tank provided a weight saving of approximately 272 kg (600 lb), and gave the External Tank

2232-466: The actual Shuttle. The ultimate launch date of STS-1 fell on the 20th anniversary of Yuri Gagarin's Vostok 1, the first spaceflight to carry a human crew. In 2001, Yuri's Night was established to celebrate both events. In a tribute to the 25th anniversary of the first flight of Space Shuttle, Firing Room 1 in the Launch Control Center at Kennedy Space Center – which launched STS-1 – was renamed

2304-502: The coast of California as Columbia crossed it near Big Sur at Mach 7 and 41,000 m (135,000 ft). Both the Mach 4.8 and Mach 2.8 roll reversals were automatically initiated and manually completed by John Young. The last RCS jet firing took place at an altitude of 17,000 m (56,000 ft) — 4,300 m (14,100 ft) lower than desired (due to a predicted risk of combustion chamber explosion). Young again took manual control for

2376-534: The cockpit — about three times as many on the Apollo command module — and many contingency procedures. STS-1 carried 22 manuals, each three inches thick and together weighing 29 kg (64 lb); the procedure for an electronics failure from a cooling system malfunction had 255 steps. During the original planning stages for the early Space Shuttle missions, NASA management under the Carter Administration felt

2448-425: The course of its mission. Right before landing, two of the orbiter's three auxiliary power units (APUs) caught fire due to a hydrazine leak, but the orbiter nonetheless landed successfully. Columbia was ferried back to KSC on December 15, 1983. The leak was later discovered after it had burned itself out and caused major damage to the compartment. By this time, Discovery had been delivered just three weeks before

2520-448: The crew strapped into their ejection seats. Meanwhile, Johnson Space Center (JSC) pilots Charlie Hayes and Ted Mendenhall were airborne over California 's Edwards Air Force Base area in a Shuttle Training Aircraft (STA) performing a final check of landing weather conditions. Auxiliary Power Units (APUs) 2 and 3 were started (to provide flight control hydraulic pressure). The 160-second twin-engine OMS de-orbit burn took place during

2592-418: The distinctive orange color which later became associated with the Space Shuttle. The song " Countdown " by Rush , from the 1982 album Signals , was written about STS-1 and the inaugural flight of Columbia . The song was "dedicated with thanks to astronauts Young and Crippen and all the people of NASA for their inspiration and cooperation". The footage of the launch was commonly played on MTV throughout

2664-416: The fields of atmospheric and plasma physics , astronomy , solar physics , material sciences , technology , astrobiology and Earth observations . The Spacelab effort went so well that the mission was extended an additional day to 10 days, making it the longest-duration shuttle flight at that time. In addition, Garriott made the first ham radio transmissions by an amateur radio operator in space during

2736-456: The first few moments after launch, and using its main engines, once the SRBs had been jettisoned, to power it back to the launch site. This scenario, while potentially necessary in the event of an early abort being called, was seen as being extremely dangerous. Young overruled both proposals, and STS-1 went ahead as the first orbital mission. The NASA managers were swayed by Young questioning the need for

2808-399: The first launchpad deaths at Cape Canaveral since the Apollo 1 fire, which killed three astronauts during preparations for the crewed Moon landing missions. The incident did not delay the launch of STS-1 less than a month later, but pilot Robert Crippen gave an on-orbit tribute to Bjornstad and Cole. A three-month inquiry determined a combination of a recent change in safety procedures and

2880-614: The first of his astronaut group to fly in space. Prior to his selection on STS-1, Crippen participated in the Skylab Medical Experiment Altitude Test (SMEAT) and also served as a capsule communicator (capcom) for all three Skylab missions and the Apollo-Soyuz Test Project (ASTP). Columbia carried Extravehicular Mobility Units (EMU) for both Young and Crippen in the event of an emergency spacewalk. If such an event occurred, Crippen would go outside

2952-458: The flight at Mach   1.06. The wind corrected value was 29 kPa (4.2 psi) (predicted 28 kPa (4.1 psi), limit 30 kPa (4.4 psi)). The two SRBs performed better than expected causing a lofted trajectory , and were jettisoned after burnout at 2 minutes and 12 seconds (at 53,000 m (174,000 ft) altitude, 2,800 m (9,200 ft) higher than planned). After 8 minutes and 34 seconds Mission Elapsed Time (MET),

3024-450: The flight. This led to many further space flights incorporating amateur radio as an educational and back-up communications tool. The Spacelab 1 mission was highly successful, proving the feasibility of the concept of carrying out complex experiments in space using non-NASA persons trained as payload specialists in collaboration with a POCC. Moreover, the TDRS-1 satellite, now fully operational,

3096-428: The launch team than say, we wish you an awful lot of luck. We are with you one thousand percent and we are awful proud to have been a part of it. Good luck gentlemen." Ignition of the three RS-25 main engines was sensed as a sharp increase in noise. The stack rocked "downwards" (towards the crew's feet), then back up to the vertical, at which point both Solid Rocket Boosters (SRBs) ignited. Crippen likened lift-off to

3168-457: The main engines were shut down (MECO, at altitude 118,000 m (387,000 ft)) and the external tank was jettisoned 18 seconds later to eventually break up and impact in the Indian Ocean . Two twin-engined Orbital Maneuvering System (OMS) engine burns of 86 seconds duration initiated at 10 minutes and 34 seconds MET and 75 seconds duration at 44 minutes 2 seconds MET inserted Columbia into

3240-450: The mission's six crew members, such as a galley and sleeping bunks. Columbia also received the more powerful Space Shuttle Main Engines introduced with Challenger , which were rated for 104% maximum thrust; its original main engines were later refurbished for use with Atlantis , which was still under construction at the time. Also added to the shuttle were higher capacity fuel cells and

3312-415: The orbiter's performance and the stresses that occurred during launch, ascent, orbital flight, descent and landing. All 113 flight test objectives were accomplished, and the orbiter's spaceworthiness was verified. During the final T−9   minute holding period, Launch Director George Page read a message of good wishes to the crew from President Ronald Reagan , ending with, "John, we can't do more from

3384-472: The orbiter, with Young standing by in case Crippen required assistance. As of April 1981 Young and Crippen trained the longest for a space mission before flying in NASA history. If STS-1 had launched in March 1979 as originally scheduled "We'd have been launched about halftrained", Young said. As no one had flown the shuttle before, they helped design the craft's controls, including 2,214 switches and displays in

3456-548: The orbiter. At the conclusion of the test, pad workers were given clearance to return to work on the orbiter, even though the nitrogen had not yet been purged due to a recent procedural change. Three technicians, John Bjornstad, Forrest Cole, and Nick Mullon, entered the compartment without air packs, unaware of the danger since nitrogen gas is odorless and colorless, and lost consciousnesses due to lack of oxygen . Several minutes later, another worker saw them and tried to help, but passed out himself. The fourth did not alert anyone, but

3528-564: The outline of the STS, and three different program levels of effort culminating with a human Mars landing by 1983 at the earliest, and by the end of the twentieth century at the latest. The system's major components consisted of: The tug and ferry vehicles would be of a modular design, allowing them to be clustered and/or staged for large payloads or interplanetary missions. The system would be supported by permanent Earth and lunar orbital propellant depots . The Saturn V might still have been used as

3600-459: The planned landing site during the entry. Consequently, a roll into a right bank was flown when the air density had increased sufficiently to raise dynamic pressure to 570 Pa (0.083 psi) (with speed still in excess of Mach 24 and approximately 78,000 m (256,000 ft) altitude). Automatic roll reversals to control energy dissipation rate and cross range steering were performed at around Mach 18.5 and Mach 9.8. The crew clearly observed

3672-539: The remainder of the flight as they went subsonic approaching the Heading Alignment Circle (HAC). A wide left turn was flown to line up with lake bed runway   23, whilst T-38 "Chase   1", crewed by astronauts Jon McBride and "Pinky" Nelson joined formation. Main gear touch down occurred on runway   23 at Edwards Air Force Base, at 339 km/h (211 mph) equivalent airspeed , slightly slower and around 800 m (2,600 ft) further down

SECTION 50

3744-428: The runway than planned. This was the result of a combination of better than predicted Orbiter lift-to-drag ratios and tail wind. Touch down time was 18:21   UTC on April 14, 1981. As they rolled to a stop, Young remarked over the radio, "This is the world's greatest all electric flying machine. I'll tell you that. That was super!" Columbia was returned to Kennedy Space Center from California on April 28, 1981, atop

3816-422: The song "Hello Earth", on Kate Bush's 1985 Hounds of Love album, contains a short clip of dialogue between Columbia and Mission Control, during the last few minutes of its descent, beginning with "Columbia now at nine times the speed of sound..." In 2006, "Collateral Damage," the 12th episode of the ninth season of the long-running Canadian-American military science fiction television show Stargate SG-1 ,

3888-453: The test, and the weight of his opinion was especially strong as he was someone who not only had been to the Moon twice, but had walked on it. He would fly the Space Shuttle again on the STS-9 mission, a ten-day flight in 1983. Let's not practice Russian roulette, because you may have a loaded gun there. The first launch of the Space Shuttle occurred on April 12, 1981, exactly 20   years after

3960-520: The time and was also the only member of NASA Astronaut Group 2 still in service. He flew twice on Project Gemini and twice on the Apollo program , walked on the Moon in 1972 as the Commander of Apollo 16 , and became Chief of the Astronaut Office in 1974. Crippen, part of NASA Astronaut Group 7 after the cancellation of the Manned Orbiting Laboratory (MOL), was a rookie and would become

4032-415: The time, included John W. Young, commander, on his second shuttle flight; Brewster H. Shaw, pilot; Owen K. Garriott and Robert A. Parker, both mission specialists; and Byron K. Lichtenberg and Ulf Merbold, payload specialists – the first two non-NASA astronauts to fly on the Space Shuttle. Merbold, a citizen of West Germany , was the first foreign citizen to participate in a Space Shuttle flight. Lichtenberg

4104-418: The vehicle now. STS-1 Pilot Robert Crippen, tribute given on-orbit to the victims of the accident. An accident occurred on March 19, 1981, that led to the deaths of three people. During a countdown test for STS-1, a pure nitrogen atmosphere was introduced in the aft engine compartment of Space Shuttle Columbia to reduce the danger of an explosion from the many other potentially dangerous gases on board

4176-495: Was a lot less vibration and noise during launch than they had expected. However, the sensations accompanying the first firing of the large Reaction Control System (RCS) jets surprised the crew. Crippen commented "it's like a big cannon just fired ... you don't like them the first time you hear them". Young reported that "the entire cabin vibrates ... it felt like the nose was being bent". Once on-orbit both crew members safed their ejection seats and unstrapped. The next critical event

4248-466: Was a researcher at the Massachusetts Institute of Technology (MIT). Prior to STS-9, the scientist-astronaut Garriott had spent 56 days in orbit in 1973 aboard Skylab . Commanding the mission was veteran astronaut John W. Young, making his sixth and final flight over an 18-year career that saw him fly twice each in Project Gemini , Apollo , and the Space Shuttle, which included two journeys to

4320-553: Was able to relay significant amounts of data through its ground terminal to the POCC. During orbiter orientation, four hours before re-entry, one of the flight control computers crashed when the Reaction Control System (RCS) thrusters were fired. A few minutes later, a second crashed in a similar fashion, but was successfully rebooted. Young delayed the landing, letting the orbiter drift. He later testified: "Had we then activated

4392-504: Was also delayed. The Shuttle first flew in 1981 , and was retired in 2011 . A second part of the system, Space Station Freedom , was approved in the early 1980s and announced in 1984 by president Ronald Reagan . However, this also became politically unviable by 1993, and was replaced with the International Space Station (ISS), with substantial contribution by Russia . The ISS was completed in 2011. The MSFC space tug

4464-637: Was beginning to wane, and the Congress would be unwilling to provide funding for most of these extended activities. Based on this, Nixon rejected all parts of the program except the Space Shuttle , which inherited the STS name. Nixon accepted Paine's resignation in July 1970 and replaced him as administrator with James C. Fletcher . As a result of funding constraints, Shuttle was significantly scaled back from its planned degree of reusability. The overall program scheduled

4536-433: Was canceled due to payload issues; it was instead followed by STS-41-B . After this mission, Columbia was taken out of service for renovations and did not fly again until STS-61-C in early January 1986. STS-9 sent the first non-U.S. citizen into space on the Shuttle, Ulf Merbold , becoming the first ESA and first West German citizen to go into space. STS-9's six-member crew, the largest of any human space mission at

4608-428: Was designed to handle a number of missions including satellite repair, transfer to geosynchronous orbit , and as the name implies, towing payloads to the nuclear shuttle. Its modular design was centered around a cylindrical propulsion module, with an attachable crew module, cargo module, and lunar landing legs to convert it to a lunar orbit-to-surface shuttle. Planned uses for NERVA included a visit to Mars by 1978 and

4680-486: Was devoted entirely to Spacelab 1, a joint NASA/ European Space Agency (ESA) program designed to demonstrate the ability to conduct advanced scientific research in space. Both the mission specialists and payload specialists worked in the Spacelab module and coordinated their efforts with scientists at the Marshall Space Flight Center (MSFC) Payload Operations Control Center (POCC), which was then located at

4752-513: Was divided into two teams, each working 12-hour shifts for the duration of the mission. Young, Parker and Merbold formed the Red Team, while Shaw, Garriott and Lichtenberg made up the Blue Team. Usually, Young and Shaw were assigned to the flight deck, while the mission and payload specialists worked inside the Spacelab. Over the course of the mission, 72 scientific experiments were carried out, spanning

4824-430: Was flown automatically. An initial angle of attack of 40° had to be maintained until through the most severe aerodynamic heating after which it was gradually reduced. At about 100,000 m (330,000 ft) altitude a light pink air glow caused by entry heating became visible, and both crew members lowered their visors. Columbia had to maneuver 583 km (362 mi) "cross range" of its orbital ground track to reach

4896-529: Was himself seen by two other people. Of those two, one alerted a security guard and another went to help the unconscious group. The security guard entered the compartment with an air pack and removed the five men from the compartment. Security procedures delayed ambulances from arriving on the scene by several minutes. Bjornstad died at the scene; Cole died on April 1 without ever regaining consciousness, and Mullon suffered permanent brain damage and died on April 11, 1995, from complications of his injuries. These were

Failure to open these by the end of the second orbit would have resulted in a return to Earth at the end of the fifth orbit, before the limited capacity of the flash evaporator cooling system was exceeded. As they opened the doors the crew noticed that they had sustained damage to thermal protection system (TPS) tiles on

5040-452: Was reached over the eastern Pacific Ocean 8,110 km (5,040 mi) from the landing site at a speed of around 28,240 km/h (17,550 mph). EI is merely an arbitrarily defined geodetic altitude of 120,000 m (390,000 ft) employed by NASA for the purposes of trajectory computations and mission planning. Above this altitude, the spacecraft is considered to be outside the "sensable atmosphere". Most of this first orbiter entry

5112-570: Was the ninth NASA Space Shuttle mission and the sixth mission of the Space Shuttle Columbia . Launched on November 28, 1983, the ten-day mission carried the first Spacelab laboratory module into orbit. STS-9 was also the last time the original STS numbering system was used until STS-26 , which was designated in the aftermath of the 1986 Challenger disaster of STS-51-L . Under the new system, STS-9 would have been designated as STS-41-A. STS-9's originally planned successor, STS-10 ,

5184-424: Was this the first launch of the Space Shuttle, but it marked the first time that solid-fuel rockets were used for a NASA crewed launch (although previous systems had used solid-fuel motors for their escape towers or retro rockets). STS-1 was also the first U.S. crewed space vehicle launched without an uncrewed powered test flight. The STS-1 orbiter, Columbia , also holds the record for the amount of time spent in
