Orbiter Space Flight Simulator v.060929 - Windows 98, 2000, ME, XP

Orbiter free space flight simulator for Windows. 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.

• Realistic physics. Planetary motion, gravitation effects, free space and atmospheric flight are accurately modelled.
• You can land your ship at a space port on a planet surface, or dock to an orbital station.
• High resolution planetary maps provide some nice visual effects.
• Configurable environment. Users can add planets, space ships and space stations to the existing universe, or design a completely new solar system from scratch. The Orbiter Software Development Kit contains libraries and sample C++ code for addon developers who want to write plugins.
