Escape from Jupiter

Some point in the not too distant future, a mining/research colony is set up one of Jupiter's moons, Io. All's ok, until a major earthquake (or what ever the Io equivalent is) destroys the communication array and puts the colony in danger of falling down the side of a canyon. In a desperate bid to escape back to Earth, the colonist have to reactive an abandoned space station and use it to get back to earth. The event's that take place on the trip (malfunctioning computers, low food, and rogue weapons satellites to name but 3) test the colonist to the limit.
