164-487: STS-89 was a Space Shuttle mission to the Mir space station flown by Space Shuttle Endeavour , and launched from Kennedy Space Center , Florida on 22 January 1998. STS-89 was originally scheduled to return Wendy B. Lawrence but returned David A. Wolf (Mir 24–25/ STS-86 ) and left Andrew Thomas on Mir . Thomas returned on STS-91 . STS-89 launched on January 22, 1998 and was the eighth of nine planned missions to Mir and
328-993: A spaceplane to a runway landing, usually to the Shuttle Landing Facility at KSC, Florida, or to Rogers Dry Lake in Edwards Air Force Base , California. If the landing occurred at Edwards, the orbiter was flown back to the KSC atop the Shuttle Carrier Aircraft (SCA), a specially modified Boeing 747 designed to carry the shuttle above it. The first orbiter, Enterprise , was built in 1976 and used in Approach and Landing Tests (ALT), but had no orbital capability. Four fully operational orbiters were initially built: Columbia , Challenger , Discovery , and Atlantis . Of these, two were lost in mission accidents: Challenger in 1986 and Columbia in 2003 , with
492-487: A NASA engineer who had worked to design the Mercury capsule, patented a design for a two-stage fully recoverable system with a straight-winged orbiter mounted on a larger straight-winged booster. The Air Force Flight Dynamics Laboratory argued that a straight-wing design would not be able to withstand the high thermal and aerodynamic stresses during reentry, and would not provide the required cross-range capability. Additionally,

A Space Shuttle crew typically had seven astronauts, with STS-61-A flying with eight. The crew compartment comprised three decks and was the pressurized, habitable area on all Space Shuttle missions. The flight deck consisted of two seats for the commander and pilot, as well as an additional two to four seats for crew members. The mid-deck
984-589: A diplomatic channel for NASA to take part in the funding of the cripplingly under-funded Russian space program. This in turn allowed the newly fledged Russian government to keep Mir operating, in addition to the Russian space program as a whole, ensuring the Russian government remained friendly towards the United States. In addition to the flights of the Shuttle to Mir , Phase One also featured seven "Increments" aboard
1148-459: A future reusable shuttle: Class I would have a reusable orbiter mounted on expendable boosters, Class II would use multiple expendable rocket engines and a single propellant tank (stage-and-a-half), and Class III would have both a reusable orbiter and a reusable booster. In September 1969, the Space Task Group, under the leadership of U.S. Vice President Spiro Agnew , issued a report calling for
1312-576: A glider. Its three-part fuselage provided support for the crew compartment, cargo bay, flight surfaces, and engines. The rear of the orbiter contained the Space Shuttle Main Engines (SSME), which provided thrust during launch, as well as the Orbital Maneuvering System (OMS), which allowed the orbiter to achieve, alter, and exit its orbit once in space. Its double- delta wings were 18 m (60 ft) long, and were swept 81° at
1476-464: A joint US/Soviet mission during the détente period of the Cold War and the docking between a US Apollo spacecraft and a Soviet Soyuz spacecraft. This was followed by the talks between NASA and Intercosmos in the 1970s about a "Shuttle– Salyut " program to fly Space Shuttle missions to a Salyut space station , with later talks in the 1980s even considering flights of the future Soviet shuttles from
1640-630: A large truss structure that spans 109 metres (358 ft), making it the largest spacecraft ever assembled. The completed station consists of five laboratories and is able to support six crew members. With over 332 cubic metres (11,700 cu ft) of habitable volume and a mass of 400,000 kilograms (880,000 lb) the completed station is almost twice the size of the combined Shuttle– Mir spacecraft. Phases Two and Three are intended to continue both international cooperation in space and zero-gravity scientific research, particularly regarding long-duration spaceflight. By spring 2015, Roscosmos , NASA, and
1804-477: A mobile platform for astronauts conducting an EVA. The RMS was built by the Canadian company Spar Aerospace and was controlled by an astronaut inside the orbiter's flight deck using their windows and closed-circuit television. The RMS allowed for six degrees of freedom and had six joints located at three points along the arm. The original RMS could deploy or retrieve payloads up to 29,000 kg (65,000 lb), which

They also agreed, in preparation for this new project, that the United States would be heavily involved in the Mir project in the years ahead, under the code name "Phase One" (the construction of the ISS being "Phase Two"). The first Space Shuttle flight to Mir was a rendezvous mission without docking on STS-63 . This
2296-528: A partial-pressure version of the high-altitude pressure suits with a helmet. In 1994, the LES was replaced by the full-pressure Advanced Crew Escape Suit (ACES), which improved the safety of the astronauts in an emergency situation. Columbia originally had modified SR-71 zero-zero ejection seats installed for the ALT and first four missions, but these were disabled after STS-4 and removed after STS-9 . The flight deck
2460-517: A partially reusable system would be the most cost-effective solution. The head of the NASA Office of Manned Space Flight, George Mueller , announced the plan for a reusable shuttle on August 10, 1968. NASA issued a request for proposal (RFP) for designs of the Integral Launch and Reentry Vehicle (ILRV) on October 30, 1968. Rather than award a contract based upon initial proposals, NASA announced
2624-541: A phased approach for the Space Shuttle contracting and development; Phase A was a request for studies completed by competing aerospace companies, Phase B was a competition between two contractors for a specific contract, Phase C involved designing the details of the spacecraft components, and Phase D was the production of the spacecraft. In December 1968, NASA created the Space Shuttle Task Group to determine
2788-481: A port-side hatch that the crew used for entry and exit while on Earth. The airlock is a structure installed to allow movement between two spaces with different gas components, conditions, or pressures. Continuing on the mid-deck structure, each orbiter was originally installed with an internal airlock in the mid-deck. The internal airlock was installed as an external airlock in the payload bay on Discovery , Atlantis , and Endeavour to improve docking with Mir and
2952-665: A result of an O-ring failing at low temperature, the SRBs were redesigned to provide a constant seal regardless of the ambient temperature. The Space Shuttle's operations were supported by vehicles and infrastructure that facilitated its transportation, construction, and crew access. The crawler-transporters carried the MLP and the Space Shuttle from the VAB to the launch site. The Shuttle Carrier Aircraft (SCA) were two modified Boeing 747s that could carry an orbiter on its back. The original SCA (N905NA)
3116-661: A second orbiter. Later that month, Rockwell began converting STA-099 to OV-099, later named Challenger . On January 29, 1979, NASA ordered two additional orbiters, OV-103 and OV-104, which were named Discovery and Atlantis . Construction of OV-105, later named Endeavour , began in February 1982, but NASA decided to limit the Space Shuttle fleet to four orbiters in 1983. After the loss of Challenger , NASA resumed production of Endeavour in September 1987. After it arrived at Edwards AFB, Enterprise underwent flight testing with
3280-645: A separate central processing unit (CPU) and input/output processor (IOP), and non-volatile solid-state memory . From 1991 to 1993, the orbiter vehicles were upgraded to the AP-101S, which improved the memory and processing capabilities, and reduced the volume and weight of the computers by combining the CPU and IOP into a single unit. Four of the GPCs were loaded with the Primary Avionics Software System (PASS), which
3444-410: A speech. After STS-4, NASA declared its Space Transportation System (STS) operational. The Space Shuttle was the first operational orbital spacecraft designed for reuse .

The RS-25 engines had several improvements to enhance reliability and power. During the development program, Rocketdyne determined that the engine was capable of safe reliable operation at 104% of the originally specified thrust. To keep the engine thrust values consistent with previous documentation and software, NASA kept
4264-508: The Columbia disaster . Beginning with STS-114 , the orbiter vehicles were equipped with the wing leading edge impact detection system to alert the crew to any potential damage. The entire underside of the orbiter vehicle, as well as the other hottest surfaces, were protected with tiles of high-temperature reusable surface insulation, made of borosilicate glass -coated silica fibers that trapped heat in air pockets and redirected it out. Areas on
4428-927: The Buran programme to a future US space station – this "Shuttle– Salyut " program never materialized however during the existence of the Soviet Intercosmos program. This changed after the Dissolution of the Soviet Union : the end of Cold War and Space Race resulted in funding for the US modular space station (originally named Freedom ), which was planned since the early 1980s, being slashed. Similar budgetary difficulties were being faced by other nations with space station projects, prompting American government officials to start negotiations with partners in Europe, Russia, Japan, and Canada in
4592-548: The Canadian Space Agency (CSA) have agreed to extend the ISS's mission from 2020 to 2024. In 2018 that was then extended out to 2030. The results of this research will provide considerable information for long-duration expeditions to the Moon and flights to Mars . Following the intentional deorbiting of Mir on 23 March 2001, the ISS became the only space station in orbit around Earth. It retained that distinction until
4756-749: The Crew Dragon Demo-2 mission in May 2020. In the late 1930s, the German government launched the " Amerikabomber " project, and Eugen Sanger 's idea, together with mathematician Irene Bredt , was a winged rocket called the Silbervogel (German for "silver bird"). During the 1950s, the United States Air Force proposed using a reusable piloted glider to perform military operations such as reconnaissance, satellite attack, and air-to-ground weapons employment.

7872-536: The International Space Station. Foale's Increment proceeded fairly normally until June 25, when a resupply ship collided with solar arrays on the Spektr module during the second test of the Progress manual docking system, TORU. The module's outer shell was hit and holed, which caused the station to lose pressure. This was the first on-orbit depressurization in the history of spaceflight. The crew quickly cut cables leading to
8036-474: The KSC. The Space Shuttle was prepared for launch primarily in the VAB at the KSC. The SRBs were assembled and attached to the external tank on the MLP. The orbiter vehicle was prepared at the Orbiter Processing Facility (OPF) and transferred to the VAB, where a crane was used to rotate it to the vertical orientation and mate it to the external tank. Once the entire stack was assembled, the MLP
8200-524: The RS-25 experienced multiple nozzle failures, as well as broken turbine blades. Despite the problems during testing, NASA ordered the nine RS-25 engines needed for its three orbiters under construction in May 1978. NASA experienced significant delays in the development of the Space Shuttle's thermal protection system . Previous NASA spacecraft had used ablative heat shields, but those could not be reused. NASA chose to use ceramic tiles for thermal protection, as
8364-505: The SRBs provided structural support for the orbiter vehicle and ET, as they were the only system that was connected to the mobile launcher platform (MLP). At the time of launch, the SRBs were armed at T−5 minutes, and could only be electrically ignited once the RS-25 engines had ignited and were without issue. They each provided 12,500 kN (2,800,000 lbf) of thrust, which was later improved to 13,300 kN (3,000,000 lbf) beginning on STS-8 . After expending their fuel,

11644-421: The deorbit burn prior to reentry. Each OMS engine produced 27,080 N (6,087 lbf) of thrust, and the entire system could provide 305 m/s (1,000 ft/s) of velocity change . The orbiter was protected from heat during reentry by the thermal protection system (TPS), a thermal soaking protective layer around the orbiter. In contrast with previous US spacecraft, which had used ablative heat shields,
11808-507: The development of a space shuttle to bring people and cargo to low Earth orbit (LEO), as well as a space tug for transfers between orbits and the Moon, and a reusable nuclear upper stage for deep space travel. After the release of the Space Shuttle Task Group report, many aerospace engineers favored the Class III, fully reusable design because of perceived savings in hardware costs. Max Faget ,
11972-590: The docking missions that followed. Five weeks after Discovery 's flight, the March 14 launch of Soyuz TM-21 carried expedition EO-18 to Mir . The crew consisted of cosmonauts Vladimir Dezhurov and Gennady Strekalov and NASA astronaut Norman Thagard , who became the first American to fly into space aboard the Soyuz spacecraft . During the course of their 115-day expedition, the Spektr science module (which served as living and working space for American astronauts)
12136-691: The early 1990s to begin a collaborative, multi-national, space station project. In the Russian Federation , as the successor to much of the Soviet Union and its space program, the deteriorating economic situation in the post-Soviet economic chaos led to growing financial problems of the now Russian space station program. The construction of the Mir-2 space station as a replacement for the aging Mir became illusionary, though only after its base block, DOS-8, had been built. These developments resulted in bringing
12300-552: The ease of refurbishing them for reuse after they landed in the ocean. In January 1972, President Richard Nixon approved the Shuttle, and NASA decided on its final design in March. The development of the Space Shuttle Main Engine (SSME) remained the responsibility of Rocketdyne, and the contract was issued in July 1971, and updated SSME specifications were submitted to Rocketdyne in that April. That August, NASA awarded
12464-479: The effects of aerodynamic and thermal stresses during launch and reentry. The beginning of the development of the RS-25 Space Shuttle Main Engine was delayed for nine months while Pratt & Whitney challenged the contract that had been issued to Rocketdyne. The first engine was completed in March 1975, after issues with developing the first throttleable, reusable engine. During engine testing,
12628-458: The eight-day flight saw the first rendezvous of a Space Shuttle with Mir , as Russian cosmonaut Vladimir Titov and the rest of Discovery 's crew approached within 37 feet (11 m) of Mir .

During the mission, more than 3,175 kilograms (7,000 lb) of experiments, supplies and hardware were transferred between
13448-487: The final Shuttle– Mir mission, STS-91 . The mission closed out Phase One, with the EO-25 and STS-91 crews transferring water to Mir and exchanging almost 4,700 pounds (2,100 kg) of cargo experiments and supplies between the two spacecraft. Long-term American experiments that had been on board Mir were also moved into Discovery . Hatches were closed for undocking at 9:07 a.m. Eastern Daylight Time (EDT) on June 8 and
13612-649: The final decision to scrub a launch was announced. In addition to the weather at the launch site, conditions had to be acceptable at one of the Transatlantic Abort Landing sites and the SRB recovery area. The mission crew and the Launch Control Center (LCC) personnel completed systems checks throughout the countdown. Two built-in holds at T−20 minutes and T−9 minutes provided scheduled breaks to address any issues and additional preparation. After
13776-435: The final outfitting of the station, completed in 2012. In 2015, a reconfiguration of the American segment was completed to allow its docking ports to accommodate NASA-sponsored commercial crew vehicles, that were expected to start visiting the ISS in 2018. As of June 2015 , the ISS has a pressurized volume of 915 cubic metres (32,300 cu ft), and its pressurized modules total 51 metres (167 ft) in length, plus
13940-471: The fire aboard the station and collision with the Progress supply vessel in 1997. The fire, caused by the malfunction of a backup solid-fuel oxygen generator (SFOG), burned for, according to various sources, between 90 seconds and 14 minutes, and produced large amounts of toxic smoke that filled the station for around 45 minutes. This forced the crew to don respirators, but some of the respirator masks initially worn were broken. Fire extinguishers mounted on
14104-518: The first docking between an American Space Shuttle and the station. On June 29, Atlantis successfully docked with Mir , becoming the first US spacecraft to dock with a Russian spacecraft since the Apollo-Soyuz Test Project in 1975. Atlantis delivered cosmonauts Anatoly Solovyev and Nikolai Budarin , who would form the expedition EO-19 crew, and retrieved astronaut Norman Thagard and cosmonauts Vladimir Dezhurov and Gennady Strekalov of

The crew used modular lockers to store equipment that could be scaled depending on their needs, as well as permanently installed floor compartments. The mid-deck contained
14760-531: The flight of Atlantis on STS-79 , which launched on September 16. STS-79 was the first Shuttle mission to carry a double Spacehab module. More than 4,000 pounds (1,800 kg) of supplies were transferred to Mir , including water generated by Atlantis 's fuel cells , and experiments that included investigations into superconductors , cartilage development, and other biology studies. About 2,000 pounds (910 kg) of experiment samples and equipment were also transferred back from Mir to Atlantis , making
14924-441: The flight of Space Shuttle Endeavour on STS-89 . The mission delivered cosmonaut Salizhan Sharipov to Mir and replaced David Wolf with Andy Thomas , following Wolf's 119-day Increment. During his Increment, the last of the program, Thomas worked on 27 science investigations into areas of advanced technology, Earth sciences , human life sciences, microgravity research, and ISS risk mitigation. His stay on Mir , considered
15088-635: The former adversaries together with the Shuttle– Mir Program, which would pave the way to the International Space Station , a joint project with several international partners. In June 1992, American President George H. W. Bush and Russian president Boris Yeltsin agreed to co-operate on space exploration by signing the Agreement between the United States of America and the Russian Federation Concerning Cooperation in
15252-491: The forward separation motors and the parachute systems that were used during recovery. The rocket nozzles could gimbal up to 8° to allow for in-flight adjustments. The rocket motors were each filled with a total 500,000 kg (1,106,640 lb) of solid rocket propellant ( APCP + PBAN ), and joined in the Vehicle Assembly Building (VAB) at KSC. In addition to providing thrust during the first stage of launch,
15416-402: The inner leading edge and 45° at the outer leading edge. Each wing had an inboard and outboard elevon to provide flight control during reentry, along with a flap located between the wings, below the engines to control pitch . The orbiter's vertical stabilizer was swept backwards at 45° and contained a rudder that could split to act as a speed brake . The vertical stabilizer also contained

Each SRB was 45 m (149.2 ft) tall and 3.7 m (12.2 ft) wide, weighed 68,000 kg (150,000 lb), and had a steel exterior approximately 13 mm (.5 in) thick. The SRB's subcomponents were the solid-propellant motor, nose cone, and rocket nozzle. The solid-propellant motor comprised the majority of the SRB's structure. Its casing consisted of 11 steel sections which made up its four main segments. The nose cone housed
15744-406: The largest spacecraft ever to have been assembled at that time in history, and the first American spacewalk using a Russian Orlan spacesuit . The program was marred by various concerns, notably the safety of Mir following a fire, a Russian spacecraft colliding with Spektr rendering it uninhabitable, financial issues with the cash-strapped Russian space program and worries from astronauts about
15908-561: The late 1950s, the Air Force began developing the partially reusable X-20 Dyna-Soar . The Air Force collaborated with NASA on the Dyna-Soar and began training six pilots in June 1961. The rising costs of development and the prioritization of Project Gemini led to the cancellation of the Dyna-Soar program in December 1963. In addition to the Dyna-Soar, the Air Force had conducted a study in 1957 to test
16072-407: The launch of Chinese Tiangong-1 space laboratory on 29 September 2011. Mir 's legacy lives on in the station, bringing together five space agencies in the cause of exploration and allowing those space agencies to prepare for their next leap into space, to the Moon, Mars and beyond. Criticism of the program was primarily concerned with the safety of the aging Mir , particularly following
16236-486: The launch pad, the Space Shuttle was used to verify the proper positioning of the launch complex hardware. Enterprise was taken back to California in August 1979, and later served in the development of the SLC-6 at Vandenberg AFB in 1984. On November 24, 1980, Columbia was mated with its external tank and solid-rocket boosters, and was moved to LC-39 on December 29. The first Space Shuttle mission, STS-1 , would be
16400-400: The majority of their science aboard the station. These missions allowed NASA and Roscosmos to learn a great deal about how best to work with international partners in space and how to minimize the risks associated with assembling a large space station in orbit, as would have to be done with the ISS. The project also served as a political ruse on the part of the American government, providing
16564-437: The mission specialists who were specifically trained for their intended missions and systems. Early in the Space Shuttle program, NASA flew with payload specialists, who were typically systems specialists who worked for the company paying for the payload's deployment or operations. The final payload specialist, Gregory B. Jarvis , flew on STS-51-L , and future non-pilots were designated as mission specialists. An astronaut flew as
16728-633: The mission was the Wake Shield Facility (or WSF), a device designed to generate new semiconductor films for advanced electronics. The WSF was flown at the end of Discovery 's robotic arm over the course of the flight. During the mission, the astronauts aboard Discovery also carried out various experiments aboard the Spacehab module in the Orbiter's payload bay, and took part in a live bi-directional audio and downlink video hookup between themselves and
16892-416: The module and closed Spektr 's hatch in order to prevent the need to abandon the station in their Soyuz lifeboat. Their efforts stabilized the station's air pressure, whilst the pressure in Spektr , containing many of Foale's experiments and personal effects, dropped to a vacuum. Fortunately, food, water and other vital supplies were stored in other modules, and salvage and replanning effort by Foale and
17056-434: The operational mission. The Space Shuttle was not launched if its flight would run from December to January, as its flight software would have required the orbiter vehicle's computers to be reset at the year change. In 2007, NASA engineers devised a solution so Space Shuttle flights could cross the year-end boundary. Space Shuttle missions typically brought a portable general support computer (PGSC) that could integrate with
17220-424: The optimal design for a reusable spacecraft, and issued study contracts to General Dynamics , Lockheed , McDonnell Douglas , and North American Rockwell . In July 1969, the Space Shuttle Task Group issued a report that determined the Shuttle would support short-duration crewed missions and space station, as well as the capabilities to launch, service, and retrieve satellites. The report also created three classes of
17384-436: The orange foam itself was sufficiently protected, and the ET was no longer covered in latex paint beginning on STS-3. A light-weight tank (LWT) was first flown on STS-6, which reduced tank weight by 4,700 kg (10,300 lb). The LWT's weight was reduced by removing components from the hydrogen tank and reducing the thickness of some skin panels. In 1998, a super light-weight ET (SLWT) first flew on STS-91 . The SLWT used
17548-437: The orbiter vehicle 18 seconds after engine cutoff and could be triggered automatically or manually. At the time of separation, the orbiter vehicle retracted its umbilical plates, and the umbilical cords were sealed to prevent excess propellant from venting into the orbiter vehicle.

This included orbital laboratories, boosters for launching payloads farther into space, the Remote Manipulator System (RMS), and optionally the EDO pallet to extend the mission duration. To limit the fuel consumption while
18204-512: The orbiter was docked at the ISS, the Station-to-Shuttle Power Transfer System (SSPTS) was developed to convert and transfer station power to the orbiter. The SSPTS was first used on STS-118, and was installed on Discovery and Endeavour . The Remote Manipulator System (RMS), also known as Canadarm, was a mechanical arm attached to the cargo bay. It could be used to grasp and manipulate payloads, as well as serve as
18368-544: The originally specified thrust at 100%, but had the RS-25 operate at higher thrust. RS-25 upgrade versions were denoted as Block I and Block II. 109% thrust level was achieved with the Block II engines in 2001, which reduced the chamber pressure to 207.5 bars (3,010 psi), as it had a larger throat area. The normal maximum throttle was 104 percent, with 106% or 109% used for mission aborts. The Orbital Maneuvering System (OMS) consisted of two aft-mounted AJ10-190 engines and
18532-468: The pair affixed a 121-pound (55 kg) Solar Array Cap to the Docking Module , for a future attempt by crew members to seal off the leak in Spektr 's hull. The mission returned Foale to Earth, along with samples, hardware, and an old Elektron oxygen generator, and dropped Wolf off on the Station ready for his 128-day Increment. Wolf had originally been scheduled to be the final Mir astronaut, but

The ET was 47 m (153.8 ft) tall and 8.4 m (27.6 ft) in diameter, and contained separate tanks for liquid oxygen and liquid hydrogen. The liquid oxygen tank was housed in the nose of the ET, and was 15 m (49.3 ft) tall. The liquid hydrogen tank comprised
19352-461: The requirements of the Space Shuttle; in July 1971, it issued a contract to Rocketdyne to begin development on the RS-25 engine. NASA reviewed 29 potential designs for the Space Shuttle and determined that a design with two side boosters should be used, and the boosters should be reusable to reduce costs. NASA and the Air Force elected to use solid-propellant boosters because of the lower costs and
19516-682: The reusability of the orbiter required a multi-use heat shield. During reentry, the TPS experienced temperatures up to 1,600 °C (3,000 °F), but had to keep the orbiter vehicle's aluminum skin temperature below 180 °C (350 °F). The TPS primarily consisted of four types of tiles. The nose cone and leading edges of the wings experienced temperatures above 1,300 °C (2,300 °F), and were protected by reinforced carbon-carbon tiles (RCC). Thicker RCC tiles were developed and installed in 1998 to prevent damage from micrometeoroid and orbital debris , and were further improved after RCC damage caused in
19680-426: The science community minimized the loss of research data and capability. In an effort to restore some of the power and systems lost following the isolation of Spektr and to attempt to locate the leak, Mir 's new commander Anatoly Solovyev and flight engineer Pavel Vinogradov carried out a salvage operation later in the mission. They entered the empty module during a so-called "IVA" spacewalk, inspecting
19844-529: The shuttle could then be constructed of lightweight aluminum , and the tiles could be individually replaced as needed. Construction began on Columbia on March 27, 1975, and it was delivered to the KSC on March 25, 1979. At the time of its arrival at the KSC, Columbia still had 6,000 of its 30,000 tiles remaining to be installed. However, many of the tiles that had been originally installed had to be replaced, requiring two years of installation before Columbia could fly. On January 5, 1979, NASA commissioned
20008-524: The smoothest of the entire Phase One program, featured weekly "Letters from the Outpost" from Thomas and passed two milestones for length of spaceflight—815 consecutive days in space by American astronauts since the launch of Shannon Lucid on the STS-76 mission in March 1996, and 907 days of Mir occupancy by American astronauts dating back to Norman Thagard's trip to Mir in March 1995. Thomas returned to Earth on
20172-532: The spacecraft separated at 12:01 p.m. EDT that day. With the landing of Discovery on June 12, 1998, the Phase One program concluded. Techniques and equipment developed during the program assisted the development of Phase Two: initial assembly of the International Space Station (ISS). The arrival of the Destiny Laboratory Module in 2001 marked the end of Phase Two and the start of Phase Three,
20336-414: The stagnant gas inside the cones before ignition.

The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. In addition to the prototype, whose completion was cancelled, five complete Shuttle systems were built and used on a total of 135 missions from 1981 to 2011, launched from
22304-512: Was 1,323 days. Space Shuttle components include the Orbiter Vehicle (OV) with three clustered Rocketdyne RS-25 main engines, a pair of recoverable solid rocket boosters (SRBs), and the expendable external tank (ET) containing liquid hydrogen and liquid oxygen . The Space Shuttle was launched vertically , like a conventional rocket, with the two SRBs operating in parallel with the orbiter's three main engines , which were fueled from
22468-462: Was 18 m (60 ft) long and 4.6 m (15 ft) wide, and could accommodate cylindrical payloads up to 4.6 m (15 ft) in diameter. Two payload bay doors hinged on either side of the bay, and provided a relatively airtight seal to protect payloads from heating during launch and reentry. Payloads were secured in the payload bay to the attachment points on the longerons . The payload bay doors served an additional function as radiators for
22632-490: Was Space Shuttle-specific software that provided control through all phases of flight. During ascent, maneuvering, reentry, and landing, the four PASS GPCs functioned identically to produce quadruple redundancy and would error check their results. In case of a software error that would cause erroneous reports from the four PASS GPCs, a fifth GPC ran the Backup Flight System, which used a different program and could control
22796-408: Was a collaborative space program between Russia and the United States that involved American Space Shuttles visiting the Russian space station Mir , Russian cosmonauts flying on the Shuttle, and an American astronaut flying aboard a Soyuz spacecraft to allow American astronauts to engage in long-duration expeditions aboard Mir . The project, sometimes called "Phase One", was intended to allow

After the Space Shuttle arrived at one of the two launchpads, it would connect to the Fixed and Rotation Service Structures, which provided servicing capabilities, payload insertion, and crew transportation. The crew was transported to the launch pad at T−3 hours and entered the orbiter vehicle, which
23452-472: Was chosen to go on the Increment instead of astronaut Wendy Lawrence . Lawrence was deemed ineligible for flight because of a change in Russian requirements after the Progress supply vehicle collision. The new rules required that all Mir crew members should be trained and ready for spacewalks, but a Russian spacesuit could not be prepared for Lawrence in time for launch. The final year of Phase One began with
23616-565: Was closed at T−2 hours. Liquid oxygen and hydrogen were loaded into the external tank via umbilicals that attached to the orbiter vehicle, which began at T−5 hours 35 minutes. At T−3 hours 45 minutes, the hydrogen fast-fill was complete, followed 15 minutes later by the oxygen tank fill. Both tanks were slowly filled up until the launch as the oxygen and hydrogen evaporated. The launch commit criteria considered precipitation, temperatures, cloud cover, lightning forecast, wind, and humidity. The Space Shuttle
23780-660: Was completed on September 17, 1976, and Enterprise was moved to the Edwards Air Force Base to begin testing. Rockwell constructed the Main Propulsion Test Article (MPTA)-098 , which was a structural truss mounted to the ET with three RS-25 engines attached. It was tested at the National Space Technology Laboratory (NSTL) to ensure that the engines could safely run through the launch profile. Rockwell conducted mechanical and thermal stress tests on Structural Test Article (STA)-099 to determine
23944-453: Was constructed between 1986 and 1996 and was the world's first modular space station. It was the first consistently inhabited long-term research station in space, and previously held the record for longest continuous human presence in space, at eight days short of ten years. Mir 's purpose was to provide a large and habitable scientific laboratory in space, and, through a number of collaborations, including Intercosmos and Shuttle– Mir ,
24108-535: Was entirely reliant on its main computer, the Data Processing System (DPS). The DPS controlled the flight controls and thrusters on the orbiter, as well as the ET and SRBs during launch. The DPS consisted of five general-purpose computers (GPC), two magnetic tape mass memory units (MMUs), and the associated sensors to monitor the Space Shuttle components. The original GPC used was the IBM AP-101B , which used
24272-657: Was equipped with an avionics system to provide information and control during atmospheric flight. Its avionics suite contained three microwave scanning beam landing systems , three gyroscopes , three TACANs , three accelerometers , two radar altimeters , two barometric altimeters , three attitude indicators , two Mach indicators , and two Mode C transponders . During reentry, the crew deployed two air data probes once they were traveling slower than Mach 5. The orbiter had three inertial measuring units (IMU) that it used for guidance and navigation during all phases of flight. The orbiter contains two star trackers to align
24436-634: Was first flown in 1975, and was used for the ALT and ferrying the orbiter from Edwards AFB to the KSC on all missions prior to 1991. A second SCA (N911NA) was acquired in 1988, and was first used to transport Endeavour from the factory to the KSC. Following the retirement of the Space Shuttle, N905NA was put on display at the JSC, and N911NA was put on display at the Joe Davies Heritage Airpark in Palmdale, California . The Crew Transport Vehicle (CTV)
24600-537: Was followed during the course of the project by nine Shuttle– Mir docking missions, from STS-71 to STS-91 . The Shuttle rotated crews and delivered supplies, and one mission, STS-74 , carried a docking module and a pair of solar arrays to Mir . Various scientific experiments were also conducted, both on shuttle flights and long-term aboard the station. The project also saw the launch of two new modules, Spektr and Priroda , to Mir , which were used by American astronauts as living quarters and laboratories to conduct
24764-403: Was later improved to 270,000 kg (586,000 lb). The Spacelab module was a European-funded pressurized laboratory that was carried within the payload bay and allowed for scientific research while in orbit. The Spacelab module contained two 2.7 m (9 ft) segments that were mounted in the aft end of the payload bay to maintain the center of gravity during flight. Astronauts entered
24928-496: Was launched aboard a Proton rocket and docked to Mir . Spektr carried more than 1,500 pounds (680 kg) of research equipment from America and other nations. The expedition's crew returned to Earth aboard Space Shuttle Atlantis following the first Shuttle– Mir docking during mission STS-71 . The primary objectives of STS-71, launched on June 27, called for the Space Shuttle Atlantis to rendezvous and perform
25092-406: Was located below the flight deck and was where the galley and crew bunks were set up, as well as three or four crew member seats. The mid-deck contained the airlock, which could support two astronauts on an extravehicular activity (EVA), as well as access to pressurized research modules. An equipment bay was below the mid-deck, which stored environmental control and waste management systems. On
25256-553: Was made internationally accessible to cosmonauts and astronauts of many different countries. The station existed until March 23, 2001, at which point it was deliberately deorbited, and broke apart during atmospheric re-entry. Mir was based upon the Salyut series of space stations previously launched by the Soviet Union (seven Salyut space stations had been launched since 1971), and was mainly serviced by Russian-crewed Soyuz spacecraft and Progress cargo ships. The Buran space shuttle
25420-591: Was moved to the Marshall Space Flight Center (MSFC) on March 13, 1978. Enterprise underwent shake tests in the Mated Vertical Ground Vibration Test, where it was attached to an external tank and solid rocket boosters, and underwent vibrations to simulate the stresses of launch. In April 1979, Enterprise was taken to the KSC, where it was attached to an external tank and solid rocket boosters, and moved to LC-39 . Once installed at
25584-587: Was never used). The Johnson Space Center (JSC) served as the central point for all Shuttle operations and the MSFC was responsible for the main engines, external tank, and solid rocket boosters. The John C. Stennis Space Center handled main engine testing, and the Goddard Space Flight Center managed the global tracking network. The orbiter had design elements and capabilities of both a rocket and an aircraft to allow it to launch vertically and then land as
25748-422: Was not launched under conditions where it could have been struck by lightning , as its exhaust plume could have triggered lightning by providing a current path to ground after launch, which occurred on Apollo 12 . The NASA Anvil Rule for a Shuttle launch stated that an anvil cloud could not appear within a distance of 19 km (10 nmi). The Shuttle Launch Weather Officer monitored conditions until
25912-418: Was tested on STS-2 and STS-3, and the first full mission was on STS-9. Three RS-25 engines, also known as the Space Shuttle Main Engines (SSME), were mounted on the orbiter's aft fuselage in a triangular pattern. The engine nozzles could gimbal ±10.5° in pitch, and ±8.5° in yaw during ascent to change the direction of their thrust to steer the Shuttle. The titanium alloy reusable engines were independent of
26076-526: Was the first shuttle flight of that year, the first flight of a Russian cosmonaut , Sergei Krikalev , aboard the American shuttle, and marked the start of increased cooperation in space for the two nations, 37 years after the Space Race began. Part of an international agreement on human space flight, the mission was the second flight of the Spacehab pressurized module and marked the hundredth " Getaway Special " payload to fly in space. The primary payload for
26240-462: Was the oldest and heaviest of the fleet, it was not suited for efficient operations at Mir 's (and later the ISS's ) 51.6-degree inclination – Columbia was therefore not retrofitted with the necessary external airlock and Orbital Docking System, and never flew to a space station. Phase One of the Shuttle– Mir program began on February 3, 1994, with the launch of Space Shuttle Discovery on its 18th mission, STS-60 . The eight-day mission
26404-430: Was the third docking mission to Mir , which also demonstrated logistics capabilities through deployment of a Spacehab module, and placed experiment packages aboard Mir 's docking module, which marked the first spacewalk which occurred around docked vehicles. The spacewalks, carried out from Atlantis 's crew cabin, provided valuable experience for astronauts in order to prepare for later assembly missions to
26568-444: Was the top level of the crew compartment and contained the flight controls for the orbiter. The commander sat in the front left seat, and the pilot sat in the front right seat, with two to four additional seats set up for additional crew members. The instrument panels contained over 2,100 displays and controls, and the commander and pilot were both equipped with a heads-up display (HUD) and a Rotational Hand Controller (RHC) to gimbal
26732-591: Was to remove electrical power connectors from a 12-year-old solar power array on the base block and reconnect the cables to the more efficient new solar power arrays. In all, Blaha spent four months with the Mir-22 cosmonaut crew conducting material science , fluid science , and life science research, before returning to Earth the next year aboard Atlantis on STS-81 . In 1997 STS-81 replaced Increment astronaut John Blaha with Jerry Linenger , after Blaha's 118-day stay aboard Mir . During this fifth shuttle docking,
26896-547: Was vented from the nose to cause the ET to tumble, ensuring that it would break up upon reentry. The ET was the only major component of the Space Shuttle system that was not reused, and it would travel along a ballistic trajectory into the Indian or Pacific Ocean. For the first two missions, STS-1 and STS-2 , the ET was covered in 270 kg (595 lb) of white fire-retardant latex paint to provide protection against damage from ultraviolet radiation. Further research determined that
