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.
Base Orbiter 2010 updated with 101016 patch, and Oglaclient-110130 external renderer by Artyom "Artlav" Litvinovich. Without Artlav's work I would not be running Orbiter in Linux.
