The plot of the 1979 In this case, the number of successes is determined by the number of successful Space Shuttle missions.

Following the Approximately four hours prior to deorbit, the crew began preparing the orbiter vehicle for reentry by closing the payload doors, radiating excess heat, and retracting the KuThe approach and landing phase began when the orbiter vehicle was at an altitude of 3,000 m (10,000 ft) and traveling at 150 m/s (300 kn). The instrument panels contained over 2,100 displays and controls, and the commander and pilot were both equipped with a The mid-deck contained the crew equipment storage, sleeping area, galley, medical equipment, and hygiene stations for the crew. NASA's transition plan had the program operating through 2010 with a transition and retirement phase lasting through 2015. The engine nozzles could gimbal ±10.5° in pitch, and ±8.5° in The RS-25 engines had several improvements to enhance reliability and power. This group outlined ambitious post-Apollo missions centered on a large permanently crewed space station, a small reusable logistics vehicle that would support it, and ultimately a human mission to Mars. The total value of equipment was over $12 billion. The mid-deck contained the airlock, which could support two astronauts on an On the first four Shuttle missions, astronauts wore modified U.S. Air Force high-altitude full-pressure suits, which included a full-pressure helmet during ascent and descent. At the time of separation, gaseous oxygen was vented from the nose to cause the ET to tumble, ensuring that it would break up upon reentry. The internal airlock was replaced with an external airlock in the payload bay on While in orbit, the crew primarily communicated using one of four [[SSpace Shuttle missions typically brought a portable general support computer (PGSC) that could integrate with the orbiter vehicle's computers and communication suite, as well as monitor scientific and payload data. The SRBs were assembled and attached to the external tank on the MLP. The Space Shuttle program was extended several times beyond its originally envisioned 15-year life span because of the delays in building the A $2.5 billion spending provision allowing NASA to fly the Space Shuttle beyond its then-scheduled retirement in 2010 passed the Congress in April 2009, although neither NASA nor the White House requested the one-year extension.Out of the five fully functional shuttle orbiters built, three remain.

The test flights only had two members each, the commander and pilot, who were both qualified pilots that could fly and land the orbiter. In 1969, President Richard Nixon formed the Space Task Group, chaired by Vice President Spiro Agnew. The Boeing CST-100 Starliner spacecraft on the Atlas V rocket the Core Stage for the Space Launch System rocket for Artemis I This included orbital laboratories,The Remote Manipulator System (RMS), also known as Canadarm, was a mechanical arm attached to the cargo bay. The final payload specialist, The crew compartment comprised three decks, and was the pressurized, habitable area on all Space Shuttle missions. NASA's space shuttle program officially began in 1972, but its roots go all the way back to a Nazi concept vehicle from the 1930s. The RMS was built by the Canadian company The Spacelab module was a European-funded pressurized laboratory that was carried within the payload bay and allowed for scientific research while in orbit. Washington, DC: General Accounting Office, 1972.Mark, Roy "Mandatory Shuttle Retirement Temporarily Postponed" (April 30, 2009) harvnb error: no target: CITEREFBridenstineGrush2019 ( harvnb error: no target: CITEREFBridenstineGrush2019 ( STS-77 Launches – May 19, 1996. Shuttle-related facilities represented over a quarter of NASA's inventory. The Air Force expected to use the Space Shuttle to launch large satellites, and required it to be capable of lifting 29,000 kg (65,000 lb) to an eastward LEO or 18,000 kg (40,000 lb) into a 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.On June 4, 1974, Rockwell began construction on the first orbiter, OV-101, which would later be named The beginning of the development of the RS-25 Space Shuttle Main Engine was delayed for nine months while NASA experienced significant delays in the development of the Space Shuttle's On January 5, 1979, NASA commissioned a second orbiter.
