- I think your number is a tad optimistic. I think the shuttle suits
- are only good for 4-5 Hours, before a recharge is done.
- Also While you have a crew of 7, at least two would stay in board.
- The pilot and the Arm operator (He may need an assistant).
- Henry is the roving expert on this. so I get.
- (oops, also i guy stays suited up in the airlock as an emergency helper.
- 8 hours/day (2 suit sorties) * 4 astronauts * 5 days = 152 hrs.
- Less if you need another guy on the flight or middeck.
- so i ball park it in at 3.5 million/hour. not counting additional
- depreciation on the suits.
-
- I would imagine the CIS is still making a killing at 5 million/hour.
