Science-Fiction, Astronauts enter a structure where time is different

An Astronaut wakes up in a strange landscape and must figure out what to do next

Four astronauts returning from man's first mission to Mars enter a time warp and crash on a 26th Century Earth devastated by atomic war. At first unaware where they are, but finding the atmosphere safe to breathe, they start exploring and find themselves in a divided future where disfigured mutants living like cavemen inhabit the surface, while the normals live comfortably below the surface but are dying as a race from lack of natural water, air and sunlight.

Maybe the 1960s, maybe the future. Seven astronauts wake up in a spaceship, not knowing where they have come from nor where they are heading. As the ship operates by itself, they have ample time to meditate, rather scientifically, on matter, life and the universe.

A Science Fiction adventure set in two different time-periods. An impending visit by extra-terrestrials is discovered by Government Agents. Ten years later we discover the outcome of the extra-terrestrial visit.

3 different individuals from the past, the present, and the future get trapped inside a room where they must work together to find their way out.

After a long space journey, an astronaut returns home to his family only to discover that he has somehow gone through a "time warp" and is now one year into the future, rendering him invisible to all those around him.

Two astronauts arrive on a strange planet and tour it in search of intelligent life; but when the encounter with the local civilization finally takes place, the mission of the travelers suffers a new and unexpected setback.

Research scientists experimenting with time warps are accidentally propelled forward into an unbearable future.

In the aftermath of a deep space collision, a lone astronaut fights for survival. But to repair his critically damaged ship, he must cross through the malfunctioning Virtual Reality chamber. Therein lurk ghosts of a life left behind on Earth, and questions about the true nature of his secret mission.
