They're in a gym! - they only get briefed on the way to the planet - orientation is ON THE PROMETHEUS!
I'm not sure if this is remotely important but I thought it was worth a mention.
Why wouldn't they tell them before they set off, and who would volunteer for a deep space mission with no knowledge of its objectives?
