A reentry capsule is the portion of a space capsule which returns to Earth following a spaceflight. The shape is determined partly by aerodynamics ; a capsule is aerodynamically stable falling blunt end first, which allows only the blunt end to require a heat shield for atmospheric entry .
The satellite designs also required that the Space Shuttle have a 4.6 by 18 m (15 by 60 ft) payload bay. NASA evaluated the F-1 and J-2 engines from the Saturn rockets, and determined that they were insufficient for the requirements of the Space Shuttle; in July 1971, it issued a contract to Rocketdyne to begin development on the RS-25 engine.
Early reentry-vehicle concepts visualized in shadowgraphs of high speed wind tunnel tests. The concept of the ablative heat shield was described as early as 1920 by Robert Goddard: "In the case of meteors, which enter the atmosphere with speeds as high as 30 miles (48 km) per second, the interior of the meteors remains cold, and the erosion is due, to a large extent, to chipping or cracking of ...
The mission lasted a total of 6 days, 2 hours, 3 minutes, and 51 seconds. STS-61-C was the last successful Space Shuttle flight before the Challenger disaster, which occurred on January 28, 1986, only 10 days after Columbia ' s return. Accordingly, commander Gibson later called the STS-61-C mission "The End of Innocence" for the Shuttle Program ...
The Space Shuttle program was the fourth human spaceflight program carried out by the U.S. National Aeronautics and Space Administration (NASA), which accomplished routine transportation for Earth-to-orbit crew and cargo from 1981 to 2011.
Columbia (STS-3) landing on Northrop Strip at White Sands Space Harbor, 30 March 1982, flanked by two T-38 chase planes. White Sands Space Harbor at White Sands Test Facility in New Mexico was an emergency landing site for the Space Shuttle and was used as a backup when the runways at Edwards Air Force Base and the Kennedy Space Center were ...
Space Shuttle Endeavour landing from orbit on STS-126, its 22nd spaceflight Reusable spacecraft are spacecraft capable of repeated launch, atmospheric reentry, and landing or splashdown. This contrasts with expendable spacecraft which are designed to be discarded after use.
The X-24B demonstrated that accurate unpowered reentry vehicle landings were operationally feasible. Top speed achieved by the X-24B was 1,164 mph (1873 km/h) and the highest altitude it reached was 74,130 feet (22.59 km). The pilot on the last powered flight of the X-24B was Bill Dana, who also flew the last X-15 flight about seven years earlier
