Odyssey 5 (TV Series)

Aroview: Good quality sci-fi series about a crew of five astronauts (led by Peter Weller) onboard a space shuttle who witness the destruction of Earth from space.

With the help of an alien being, they then try to go back in time to prevent this from happening. Unfortunately, only one season was ever made, so we never actually find out what happened; but even so, the characters are solid and it has its thoughtful moments.
