Lifeforce

The crew of the joint British and American Space Shuttle Churchill, under the command of Colonel Tom Carlsen, finds a 150-mile-long (240 km) spaceship hidden in the coma of Halley's Comet. Inside, the crew discovers hundreds of desiccated bat-like creatures and three naked humanoid bodies (two male and one female) in suspended animation within glass containers. The crew recovers a bat-alien and the three bodies and begins the return trip to Earth. However, during the return journey, mission control loses contact with Churchill. A rescue mission is launched to investigate.
