Orion spacecraft
From SPACEwiki
Orion is a spacecraft being designed by Lockheed Martin for NASA, the space agency of the United States. Orion development began as part of the Constellation program, where Orion would fulfill the function of a Crew Exploration Vehicle.
Each Orion spacecraft is projected to carry a crew of four to six astronauts. The spacecraft is designed to be launched by the Ares I, a launch vehicle which is also part of the Constellation program. Constellation plans to send human explorers back to the Moon by 2020, and then onward to Mars and other destinations in the Solar System. On August 31, 2006, NASA awarded Lockheed Martin the contract to design, develop, and build Orion.
Orion would launch from Launch Complex 39 at Kennedy Space Center, the same launch complex that currently launches the space shuttle. While shuttle operations continue from launch pad 39A, 39B is being readied for Ares launches. NASA will use Orion spacecraft for its human spaceflight missions after the last shuttle orbiter is retired in 2010. The first crewed Orion flight is anticipated in 2015. Subsequent flights will visit the International Space Station. If commercial orbital transportation services are unavailable, Orion will handle logistic flights to the Station. After that, Orion is to become a key component of human missions to the Moon and Mars.
