Story It is 342 days after leaving Earth orbit, and Moonbase Alpha is recovering after a recent encounter with a space warp. Without warning, the Moon was flung six light-years across space. Though there were no casualties, one life-support system was critically damaged. A quantity of titanium is required to complete repairs. Commander John Koenig dispatches a survey Eagle to reconnoitre a nearby solar system for the rare mineral. From the new, underground Command Centre, the staff tracks Eagle One as it approaches a near-habitable planet. Though the atmosphere is breathable, the barren surface is covered with active volcanoes and temperatures average 180° Fahrenheit. Computer analysis reveals large deposits of titanium, and Astronauts Bill Fraser and Ray Torens are recalled.

Koenig insists there must be intelligent life on the planet. Scientific officer Lew Picard declares no life as they know it could exist in that environment. Just then, a middle-aged alien man appears on the big screen, introducing himself as Mentor of the planet Psychon. Koenig immediately accuses the being of attacking an unarmed survey ship—which, Mentor counters, was trespassing on his planet. After a lengthy exchange, an understanding is reached. Mentor agrees to release the pilots. Their vessel is damaged, however; another Eagle must be sent to collect them. In the interests of peace, the alien will also give them the titanium, asking that a science specialist be sent to discuss the details. Mentor also asks for them to bring
