Probe ship

Probe ships were a type of spacecraft used by the Morestrans. Controller Salamar captained a probe ship that travelled to Zeta Minor to make contact with Professor Sorenson's expedition, who had not been heard from since their arrival on the planet.

Only by jettisoning the minerals taken from Zeta Minor was the probe ship able to leave, the anti-matter creature preventing its escape until the canister Sorenson placed the minerals in was restored to it. (TV: Planet of Evil)
