What Happens in Mission Stardust: Full Plot Summary

The whole story of Mission Stardust (1967) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

On a mission to locate a source of radioactive material more powerful than uranium, Major Perry Rhodan leads a four-man expedition to the Moon aboard the rocket Stardust. On the Moon, they discover a stranded Arkonide spaceship, where Crest John Karlsen is a scientist suffering from leukemia, and Commander Thora Essy Persson is trying to save him along with a crew of robots. The cure for Crest is available on Earth, so the team travels down in an Arkonide shuttle to fetch a physician who can deliver it.

To obtain the cure, Luis Dávila as Captain Mike Bull travels with them to Earth in search of a doctor who can deliver the cure.

Back on Earth, one crewman turns traitor, feeding information to a crime lord who covets the Arkonide material and sees the Moon mission as a stepping stone to a bigger prize.

The crime lord arranges to replace the doctor and nurses with his own people, and upon reaching the Arkonide ship they kidnap Thora to seize Arkonide technology.

Crest provides Rhodan and Bull with Arkonide technology, which helps them rescue Thora as well as the real doctor, who cures Crest.

With the mission's success, they depart the Moon in the Stardust, promising to return with the materials the Arkonides need to repair their ship.

  • space power
  • rare material
Q8

Why do the robots attack the Earth crew?
