Slingshot

Three astronauts have embarked on trip to Saturn's moon, Titan. They spend 90 day periods in hibernation, being revived to perform maintenance and communication tasks, before returning to another hibernation period. The hibernation drugs come with a warning of side effects of disorientation upon awakening. The lead character John increasingly begins having haluicinations of his ex-partner Zoe being on board and after a collision causes some damage to the spacecraft there is more instability created between the increasingly paranoid crew.
