ORBITER - Space Flight Simulator torrent

ORBITER is a free flight simulator that goes beyond the confines of Earth\\\\\\\\\\\\\\\'s atmosphere. Launch the Space Shuttle from Kennedy Space Center to deploy a satellite, rendezvous with the International Space Station or take the futuristic Delta-glider for a tour through the solar system - the choice is yours.
But make no mistake - ORBITER is not a space shooter. The emphasis is firmly on realism, and the learning curve can be steep. Be prepared to invest some time and effort to brush up on your orbital mechanics background. Good starting points are JPL\\\\\\\\\\\\\\\'s Basics of Space Flight, and R. Braeunig\\\\\\\\\\\\\\\'s Rocket & Space Technology.

For discussion with other Orbiter users, have a look at the Orbiter forum. More information and resources for users and developers can be found under the Orbiter Wikipedia entry and the OrbiterWiki site, both maintained by the Orbiter community.
