As far as I'm aware, there are no trailers for this over the pond yet. It came out on Friday here in England, though, and it's pretty amazing. It's about a mission sent to the dying sun to re-ignite it with a special bomb with the mass of Manhattan Island (Okay, so it's a little pseudo-science). It's directed by Danny Boyle (Trainspotting, 28 Days Later) and conjures images of Dark Star, 2001 and Silent Running.
It's visually stunning, and personally I loved it. It was very divisive in the group I saw it with, though. There are a couple of points where you just have to accept the physics even if they're not really correct, but really it's less about that than a character study of loneliness and a closeness to something so powerful it may as well be God, and what happens if you're left in that environment far longer than planned.
