#NASA SPACE SHUTTLE WEIGHT SERIES#
In 1992, Endeavour, a replacement orbiter for the destroyed Challenger, flew its first mission.īetween 19, NASA conducted a series of shuttle missions to the orbiting Russian space station Mir to give the agency experience in station operations in anticipation of the construction of the modular International Space Station (ISS). After the accident, the shuttle fleet was grounded until September 1988 to allow NASA to correct the design flaws and implement associated administrative changes in the shuttle program. Hot gases leaking from the joint eventually ignited the fuel in the shuttle’s external tank, causing the explosion. The presidential commission appointed to investigate the accident determined that a joint seal in one of the solid rocket boosters had failed as a result of mechanical design problems, which were exacerbated by the unusually cold weather on the morning of the launch. On January 28, 1986, Challenger, carrying seven astronauts, exploded shortly after liftoff, killing all aboard including a private citizen, schoolteacher Christa McAuliffe. The success of NASA's programs had become almost routine by the 1980s. Seventh launch of the space shuttle and second liftoff of Challenger, on June 18, 1983. Although the orbiter lifted off vertically like an expendable rocket launcher, it made an unpowered descent and landing similar to a glider. It released the tank, which disintegrated on reentering the atmosphere. After attaining 99 percent of its orbital velocity, the orbiter had exhausted the propellants in the external tank. The boosters were jettisoned about two minutes after liftoff and were returned to Earth by parachute for reuse. During launch the boosters and the orbiter’s main engines fired together, producing about 31,000 kilonewtons (7 million pounds) of thrust. At liftoff the entire system weighed 2 million kilograms (4.4 million pounds) and stood 56 metres (184 feet) high. space shuttle consisted of three major components: a winged orbiter that carried both crew and cargo an external tank containing liquid hydrogen (fuel) and liquid oxygen (oxidizer) for the orbiter’s three main rocket engines and a pair of large, solid-propellant, strap-on booster rockets. Formally called the Space Transportation System (STS), it lifted off into space for the first time on April 12, 1981, and made 135 flights until the program ended in 2011. National Aeronautics and Space Administration (NASA). Space shuttle, also called Space Transportation System, partially reusable rocket-launched vehicle designed to go into orbit around Earth, to transport people and cargo to and from orbiting spacecraft, and to glide to a runway landing on its return to Earth’s surface that was developed by the U.S. SpaceNext50 Britannica presents SpaceNext50, From the race to the Moon to space stewardship, we explore a wide range of subjects that feed our curiosity about space!.Learn about the major environmental problems facing our planet and what can be done about them!
