An orbital propellant depot is a cache of propellant that is placed in orbit around Earth or another body to allow spacecraft or the transfer stage of the spacecraft to be fueled in space. It is one of the types of space resource depots that have been proposed for enabling infrastructure-based space exploration . [ 1 ]
A service module (also known as an equipment module or instrument compartment) is a component of a crewed space capsule containing a variety of support systems used for spacecraft operations. Usually located in the uninhabited area of the spacecraft, the service module serves a storehouse of critical subsystems and supplies for the mission such ...
The second crewed spacecraft selected by NASA for its CCDev program was Boeing's CST-100 Starliner, which, like SpaceX's Dragon 2 spacecraft, uses a "pusher" launch escape system, consisting of four launch abort engines mounted on the service module that can propel the spacecraft away from its Atlas V launch vehicle in an emergency on the pad ...
A pyrotechnic valve, also explosive actuated valve, short pyro valve or pyrovalve is a one time use propulsion component often used to control propellant or pressurant systems aboard spacecraft or space probes. The device is activated by an electric signal, upon which one or several small explosive charges are ignited.
Boeing Starliner Spacecraft 2 is the first of two active Boeing CST-100 Starliner spacecraft developed and built under NASA's Commercial Crew Program.The spacecraft was originally scheduled to make its maiden flight on Boe-CFT, the first crewed flight test of the Starliner spacecraft, although following the partial failure of the other CST-100 on Boe-OFT which required a repeat uncrewed test ...
The payload and spacecraft bus may be different units or it may be a combined one. The booster adapter provides the load-carrying interface with the vehicle (payload and spacecraft bus together). The spacecraft may also have a propellant load, which is used to drive or push the vehicle upwards, and a propulsion kick stage.
A reusable launch vehicle has parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be
It is a revision of the Soyuz spacecraft introduced in 2001 and was in use until 2012 after being superseded in 2010 by the Soyuz TMA-M. While it looks identical to the earlier Soyuz-TM on the outside, the spacecraft features several changes to accommodate requirements requested by NASA to better service the International Space Station.
