CAPE CANAVERAL, Fla. – Parachutes recovered from sea after the launch of space shuttle Endeavour on the STS-126 mission are suspended from a hanging monorail system at the Parachute Refurbishment Facility at NASA's Kennedy Space Center in Florida. The parachutes are used to slow the descent of the solid rocket boosters that are jettisoned during liftoff. The monorail will transport each parachute into a 30,000-gallon washer and a huge dryer heated with 140-degree air at 13,000 cubic feet per minute. One pilot, one drogue and three main canopies per booster slow the booster’s fall from about 360 mph to 50 mph. After the chutes are cleaned and repaired, they must be carefully packed into their bags so they will deploy correctly the next time they are used. Photo credit: NASA/Jim Grossmann KSC-08pd3740

The Space Shuttle program was the United States government's manned launch vehicle program from 1981 to 2011, administered by NASA and officially beginning in 1972. The Space Shuttle system—composed of an orbiter launched with two reusable solid rocket boosters and a disposable external fuel tank— carried up to eight astronauts and up to 50,000 lb (23,000 kg) of payload into low Earth orbit (LEO). When its mission was complete, the orbiter would re-enter the Earth's atmosphere and lands as a glider. Although the concept had been explored since the late 1960s, the program formally commenced in 1972 and was the focus of NASA's manned operations after the final Apollo and Skylab flights in the mid-1970s. It started with the launch of the first shuttle Columbia on April 12, 1981, on STS-1. and finished with its last mission, STS-135 flown by Atlantis, in July 2011.
