Exercise for Death

Secretary Masters, the top Man in the Solar Guard, pays a visit to Space Academy and receives an unfavorable first impression of the Polaris Cadets. Later, as a part of an exercise, and to impress Secretary Masters who is aboard the Polaris and to atone for their previous embarrassment, the Cadets must knock out a robot rocket in Mars orbit. They hit it as planned, but the robot rocket careens wildly out of control, posing a deadly threat to other ships. The Cadets voluntarily risk their necks to try to stop it.
