Tom Corbett, Space Cadet S01 E04 Graveyard of the Rockets

The Space Cadets, along with Captain Strong, Commander Arkwright, and Dr. Joan Dale, seek an Academy scientist lost on a distant planet in an uncharted solar system. Their search takes them to the legendary Rocket Graveyard, where dozens of lost ships have accumulated over the past 200 years. The graveyard appears to be otherwise deserted, but there are unknown foes waiting -- not all of which are human.
