re: Shuttle rescue missions
Yes, every launch has it's risk. I think O'Keef decided not to risk 2 Shuttles on 1 mission.
What I don't understand is how are they going to safely deorbit Hubble for reentry without a Shuttle launch. The talk of attaching a robotic booster doesn't sound like it will be cheap and what happens if that mission has problems?
