Moontrap

In 1988, Col. Jason "Einstein" Grant and Ray "The Penetrator" Tanner are piloting the space shuttle Camelot when they see an abandoned spaceship drifting near the moon. Grant leaves Camelot to investigate the spaceship and finds a brown cocoon and the remains of a human body. They bring their findings to the NASA and the scientists learn that they have fourteen thousand years. Soon the cocoon opens and the intelligence inside builds a robot that kills many security guards before Grant shoots and destroys it. Now Grant and Tanner are assigned to return to the moon with the pilot George to seek out the origin of the mysterious civilization.
