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 .
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 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.
It discusses the history of the Space Shuttle program, and documents the post-disaster recovery and investigation efforts. [90] Michael Leinbach, a retired Launch Director at KSC who was working on the day of the disaster, released Bringing Columbia Home: The Untold Story of a Lost Space Shuttle and Her Crew in 2018. It documents his personal ...
All sites have runways of sufficient length to support the landing of a Space Shuttle, and included personnel from NASA as well as equipment to aid a space shuttle landing. [12] Zaragoza Air Base features Runway 30L with a length of 12,109 ft (3,691 m); [ 13 ] Morón Air Base features an 11,800 ft (3,600 m) runway; [ 14 ] and Istres Air Base ...

The primary goal was to have the RV change its path during reentry so that anti-ballistic missiles (ABMs) would not be able to track their movements rapidly enough for a successful interception. The first known example was the Alpha Draco tests of 1959, followed by the Boost Glide Reentry Vehicle (BGRV) test series, ASSET [16] and PRIME. [17]
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.
