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 underlying aerodynamic concepts have been used to produce maneuverable reentry vehicles (MARV), to increase the accuracy of some missiles like the Pershing II. More recently, the concepts have been used to produce hypersonic glide vehicles (HGV) to avoid interception as in the case of the Avangard .
The ARD is an unmanned 3-axis stabilised automated capsule which served as experimental reentry vehicle primarily for technology-proving and data-gathering purposes. [2] In terms of its shape, the vehicle bares an external resemblance to a 70 per cent-scale version of the American Apollo capsule, and considered by the ESA to be a 50 per cent-scale vehicle of a prospective potentially ...
Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) was a NASA mission to test inflatable reentry systems. [1] It was the first such test of an inflatable decelerator from Earth-orbital speed. LOFTID was launched on an Atlas V 401 in November 2022 as a secondary payload, along with the JPSS-2 weather satellite. [2]
The Starliner left its docking port at the space station just after 6 p.m. ET, according to NASA. The capsule spent about six hours free-flying through orbit as it slowly made its descent toward home.
The assembled SHEFEX II body. SHEFEX (Sharp Edge Flight Experiment), is an experiment conducted by the German Aerospace Center (DLR), for the development of some new, cheaper and safer design principles for space capsules, hypersonic vehicles and spaceplanes with re-entry capability in the atmosphere and their integration into a complete system.
The vehicle soared through multiple milestones during Thursday’s test flight, including the survival of the Starship capsule upon reentry during peak heating in Earth’s atmosphere and ...
