This is a planetary motion simulation turned into a game. You are piloting a space ship that was on a mission beyond the orbit of Mars when a collision with a micro-asteroid permanently disabled your comm and main navigation computer. To survive, you will need to pilot your ship back to Mars.
Win Condition: Both your speed and distance relative to Mars go below preset values at the same time.
Loose Condition: X number of Martian years have passed and you run out of life support.
