Image credit: NASA/JPL NASA had conducted a series of paper-projects throughout the 1960s on the topic of reusable spacecraft to replace their expedient "one-off" systems like Mercury, Gemini, and Apollo.
ALT X-Prize The final defining moment was when NASA, in desperation to see their only remaining project saved, went to the Air Force for its blessing. NASA asked that the AF place all of their future launches on the shuttle instead of their current expendable launchers (like the Titan II), in return for which they would no longer have to continue spending money upgrading those designs -- the shuttle would provide more than enough capability.
Space Shuttle Enterprise Space Shuttle Columbia disaster Skylab was actually the refitted S-IVB third stage of a Saturn V booster, a leftover from the Apollo program originally intended for one of the canceled moon landing missions (Apollos 18-20). A product of the Apollo Applications program (a program tasked with finding long-term uses for Apollo program hardware), Skylab was originally planned as a minimially-altered S-IVB to be launched on a Saturn IB rocket. The small size of the IB would have required Skylab to double as a rocket stage during launch, only being retrofitted as a space station once on-orbit. With the cancellation of Apollo missions 18-20 a Saturn V was made available and thus the "Wet Workshop" concept, as it was called, was put aside and Skylab was launched dry and fully outfitted. Skylab's grid flooring system is a highly visable legacy of the wet workshop concept. Following the last mission the Station was positioned in a parking orbit expected to last at least 8 years. Increased solar activity heating the outer layers of the earth's atmosphere and thereby increasing drag on the Station led to an early reentry on July 11, 1979. Skylab disintegrated over Western Australia and the Indian Ocean, casting large pieces of debris in populated areas (without injury). The reentry prevented any further use by the then unfinished Space Shuttle as was envisioned by some at NASA. Two flight-quality Skylabs were built, the second, a backup, is on display at the National Air and Space Museum in Washington, DC.Shuttles

Tim Finn and Liam O'Maonlai. ALT is also an abbreviation for Assistant Language Teacher, the job title of people on the JET Programme. ALT was also an acronym by the NASA for the Approach and Landing Tests of the Space Shuttle in 1976. ALT can mean alternative lengthening of telomeres, a mechanism (other than telomerase) that cells use to maintain telomere length.
two weeks. This must be essentially the same vehicle: propellant can be replaced, but most of the rest of the vehicle must be reused. Even NASA's space shuttle falls short of this performance requirement, since it takes much more than two weeks to ready a given shuttle between flights. This prize foundation was created to encourage the development of private space travel, which is why government-funded projects are not allowed. The X Prize is designed to help create a space industry, and is modeled after many prizes from the early 20th century that helped prod the development of air flight—notably the $25,000 Orteig Prize that spurred Charles Lindbergh to make his solo flight across the Atlantic Ocean. The X-Prize Foundation (based in St. Louis, Missouri) maintains a list of organizations registered

Space Shuttle Enterprise The Shuttle Orbiter Enterprise (NASA Designation: OV-101) was the first Space Shuttle built for NASA. It was initially constructed without engines or a functional heat shield and was therefore not capable of space operations without a refit. It was intended to be the second space shuttle to fly after the Space Shuttle Columbia even though it was built first, however, it was found to be cheaper to refit a test article (STA-099) into the Space Shuttle Challenger. Originally planned to be called Constitution, the test vehicle was renamed following a write-in campaign after the starship featured on the television show Star Trek, which in turn was named for the various ships named USS Enterprise. Amusingly, in one of the subsequent Star Trek movies
Space Shuttle Columbia disaster Crew of STS-107 on launch day () STS-107 was a space shuttle mission by NASA using the Space Shuttle Columbia. The entire seven member crew was killed on February 1, 2003, when the shuttle disintegrated over Texas during reentry into the Earth's atmosphere.This was the second total loss of a Space Shuttle, the first being Challenger.

America's first space station, the 75 ton Skylab was launched May 14, 1973 by a two-stage version of the Saturn V booster (the SL-1 mission). Severe damage was sustained during launch, including the loss of the station's micrometeoroid shield/sun shade and one of its main solar panels. Debris from the lost micrometeroid shield further complicated matters by pinning the remaining solar panel to the side of the station, preventing its deployment and thus leaving the station with a huge power deficit. The station underwent a extensive repair by the first crew launched on May 25, 1973 (the SL-2 mission) atop a Saturn 1B. Two additional missions followed on July 28, 1973 (SL-3) and November 16, 1973 (SL-4) with stay times of 28, 59, and 84 days, respectively. The last Skylab crew returned to Earth on February 8, 1974.
