Vehicles such as the Apollo spacecraft and the Space Shuttle required more power than could be supplied by batteries or solar panels, and so relied on hydrogen fuel cells to provide several kilowatts of power for hundreds of hours. [2] A reserve battery is a primary battery that keeps its chemical reactants separated until needed. This improves ...
The Leonardo MPLM, also known as MPLM-1, was one of three Multi-Purpose Logistics Modules which were operated by NASA to transfer supplies and equipment to and from the International Space Station. Leonardo was used for eight of the twelve MPLM flights to the space station, with Raffaello being used for the other four.
Orbital replacement units are parts of the main systems and subsystems of the external elements of the ISS. Affecting the control of the cooling system, the movement and control of the solar arrays and SARJ as well as the flow of power throughout the station from solar arrays to the heat rejection system as part of the External Active Thermal Control System (EATCS).

The space frame was completed in February 1985 and major internal equipment was installed by October 1986. The Mir-2 space station was redesigned after the failure of the Polyus orbital weapons platform core module to reach orbit. Zvezda is around 1 ⁄ 4 the size of Polyus, and has no armaments.
As of 2023, SpaceX and NASA are the only launch providers which have achieved first-stage reuse of an orbital vehicle with SpaceX’s two-stage Falcon 9 and 2.5-stage Falcon Heavy, and NASA’s Space Shuttle Solid Rocket Boosters. Rocket Lab has recovered multiple first stages of their Electron rocket, but has not flown them again.
The Orbital Maneuvering System (OMS) is a system of hypergolic liquid-propellant rocket engines used on the Space Shuttle and the Orion spacecraft.Designed and manufactured in the United States by Aerojet, [1] the system allowed the orbiter to perform various orbital maneuvers according to requirements of each mission profile: orbital injection after main engine cutoff, orbital corrections ...
In February 2003 Spacehab received $17.7 million from its commercial insurance policy. In January 2004, Spacehab filed a formal claim against NASA for the amount of $87.7 million for the loss caused by the Columbia accident and in October 2004 NASA paid the company $8.2 million. [1] [2] In February 2007, Spacehab dropped all litigation against ...
