What is a shuttle?
SHE SHE SHOP LEANT, Officially called space transport system, or STS, has been a primary American spacecraft used for missions with crew since 1981. Five space shuttles have been built at a total cost of approximately $ 2.2 billion: Columbia, Challenger, Discovery, Atlantis and Endeavor. One other shuttle, Enterprise, was immense and was built only for testing purposes.
Since December 2007 there have been 118 successful shuttle missions and two failures. The two failures of Challenger in 1986 and Columbia in 2003 were caused by the catastrophic failure of missiles and disintegration during the reentry. During both occasions, all seven astronauts were killed on board. The concept of a repeatedly applicable starting vehicle was originally introduced as a way of reducing the cost of Spaceflight, although it failed in this respect, instead the most expensive project in NASA history was a remarkable useful useful burden of the shuttle.LED Hubble, a Galileo spacecraft (which continued Jupiter's months studio), Magellan spacecraft, X -ray Observatory Chandra and components of the International Space Station, the International Space Project in History.
Space Shutwle is powered by three different means: double fixed rocket boosters, a large outer tank powered by liquid oxygen and hydrogen at cryogenic temperatures and orbital maneuver. Two fixed rackets raise the shuttle out of the pad and are released from the orbiter two minutes after starting. Strengers descent over parachute for later recovery.
orbiter specifications are as follows:
• length: 122,17 ft (37,24 m)
• wing span: 78.06 ft (23.79 m)
• height: 58.58 ft (17.86 m)
• empty weight: 151.205 lb (68 585 kg)
• • gross weight lifting: £ 240,000 (109,000 kg)
• Maximum landing weight: 230 000 lb (104,000 kg)
• Maximum payload: 55 250 pounds (25 061 kg)
• Dimensions Bay Bay Payload: 15 ft × 60 ft (4.6 m × 18.3 m)
• Operating altitude: 100 to 520 naval miles (185 to 960 km)
• speed: 25 404 ft/s (743 m/s, 27 875 km/h, 17 321 million/h)
Space Shegtowle will be discarded in 2010, which is to be replaced by the Orion vehicle, designed to carry the crews to the Moon and further.
