After an explosion in space and subsequent two-minute radio-out period, two astronauts return home to their wives. Slightly it's revealed that they're not the same as they were.

A pair of shuttle astronauts leave their spacecraft to repair a satellite. There's an explosion. NASA loses contact for two minutes, but the both are rescued and safely returned to Earth. Eventually it becomes evident that neither of the astronauts is quite the same.—JHole

Astronaut Spencer Armacost was on a mission when he suddenly lost contact. When he got home, to friends he was the same, but to his wife he was different. She becomes pregnant, but as time progresses she begins to feel like the lives inside of her are not of this world.—Brian Levin <[email protected]>

A space shuttle in orbit to repair a damaged satellite is forced to return to Earth after NASA loses contact with astronauts Spencer Armacost and Alex Streck for two minutes. Both were outside the spacecraft when the incident occurred. While Armacost seems to be unaffected, Streck has a much harder time recovering from whatever happened to them. Over time, Armacost's wife Jillian begins to note subtle changes in him. Egged on by a former NASA employee, she begins to believe that her husband is something else. She also learns that she is pregnant.—garykmcd
