What Movie or TV Show Episode is this?

I remember watching this about 7 years ago. It was about 5 astronauts in space. There was a female Russian, a male American, I think a male Frenchman, and an female Asian. They get suspicious of something and find out that the other crew member is an android. It's a lot like Ash in Alien, they knock his head off but his hand walks off and sets the self destruct on the ship. The American and Russian escape and awake in a facility. They were in a simulation the entire time, as they head up an elevator in anger at their superiors for doing that to them the realize that Earth has been destroyed and is just an apocalyptic wasteland. It might have been a movie or it might have been an episode of a TV show.
