A cloud of dust and brilliant lights draws the moon into its center and then keeps moving past it. Moonbase Alpha sustains moderate damage, but it also seems to have been thrown far from where its normal wanderings would have taken it. One member of the grew, Regina Kesslann, hasn’t quite recovered from the collision with the dust cloud, insisting that she saw the moon vanishing into the distance – from inside the Moonbase. She also seems to think that Commander Koenig and Alan Carter died during the incident. As the moon approaches a solar system, instruments seem to indicate that the star is Earth’s sun – and that the third planet orbiting that star is Earth itself. Koenig grows skeptical as the moon slips into its old orbit without incident, though the rest of the crew is eager to return home without asking too many questions. The one person who continues to have difficulty is Regina, and Dr. Russell is at a loss to explain her condition. When Professor Bergman does a closer inspection, he discovers something even more disturbing: the Earth is now a radioactive wasteland, incapable of supporting human life.
