Orion (Orion Multi-Purpose Crew Vehicle or Orion MPCV) is a partially reusable crewed spacecraft used in NASA's Artemis program. The spacecraft consists of a Crew Module (CM) space capsule designed by Lockheed Martin that is paired with a European Service Module (ESM) manufactured by Airbus Defence and Space .
The Orion Main Engine (OME) was a 33-kilonewton (7,500 lbf) thrust, pressure-fed, regeneratively cooled, storable bi-propellant rocket engine to be made by Aerojet. The OME was an increased performance version of the 27-kilonewton (6,000 lbf) thrust rocket engine used by the Space Shuttle for its Orbital Maneuvering System.
The Orion CEV became part of NASA's Constellation Program to send human explorers back to the Moon, and then onward to Mars and other destinations in the Solar System. After Constellation was cancelled, it was envisioned for emergency evacuation of the International Space Station , then retained for revived Solar System exploration plans.
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 ...
The Orion Asteroid Mission was a proposed NASA mission to a near-Earth asteroid (NEA) which would use the standard Orion spacecraft, and a landing module based on a modified Altair lunar lander. Most of its specific details are now deprecated by the cancellation of the Constellation Program and related designs.
The Space Launch System (SLS) is an American super heavy-lift expendable launch vehicle used by NASA.As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory.
In January 2015, NASA and Lockheed Martin announced that the primary structure in the Orion spacecraft used on Artemis I would be up to 25% lighter compared to the previous one (EFT-1). This would be achieved by reducing the number of cone panels from six (EFT-1) to three (EM-1), reducing the total number of welds from 19 to 7 [ 34 ] and saving ...
The service module supports the crew module from launch through separation prior to reentry. It provides in-space propulsion capability for orbital transfer, attitude control, and high altitude ascent aborts. It provides the water and oxygen needed for a habitable environment, generates and stores electrical power, and maintains the temperature ...
