Nobody has mentioned my two favorites: Apollo 13 and Galaxy Quest.
Apollo 13 is the most accurate space movie ever made. It could have been boring under some directors, but it turned out to be epic. If you can find the commentary track with the real Jim and Marilyn Lovell, it's well worth listening to.
Galaxy Quest is technically a parody of Star Trek (The Original Series), but even Trekkies agree that it belongs on the official list of the best Star Trek movies. It's not just hilarious; it also has a well-constructed plot.
