An unknown space phenomenon seems to duplicate the moon (and everyone on it), then sends the doppelgänger into hyperspace. Everyone recovers except Regina Kesslann, who believes she's been living back "home" and is married to Alan Carter. In an astonishing coincidence, the Alphans discover the moon returning to Earth's solar system and Regina mysteriously dies when the moon re-enters the Earth's orbit. The Alphans are unable to contact anyone on Earth, which seems to have experienced an extinction event. Suddenly another moon appears in Earth's orbit which is discovered to be on a collision course with their own. A recon mission is assembled to find answers.
Did You Know?
When Koenig and Carter discover the crashed Eagle and their deceased duplicates inside, we see Carter was piloting the Eagle and Koenig was the copilot. In the normal time line, Koenig always pilots the Eagle (right seat), and Carter is the copilot (left seat.) See more
It is impossible to have two bodies (spacecraft, Moons, whatever) in the same orbit and one going faster. If one Moon was, it would have to be in a different orbit, most likely in lower orbit. See more
