Some proposed missions for the SLS

To take advantage of available hardware left over from the Shuttle Era.  One rationale given is to fully test the SLS.  It is currently scheduled to have only one test.  That may not be enough to iron out all the kinks before sending people up on a mission.

Four tests were proposed:

1. The launch of a Bigelow space hab.  A big one.
2. A hypergravity centrifuge deployed in LEO.  This will test the technique of hypergravity on lessening the effects of weightlessness on the human body during long stays in space.
3. Two others unspecified.  Perhaps the Tito mission around Mars?

Or the engines could be used to move up the schedule a bit so that the Tito mission may be possible.  The Tito mission will still need the DUUS engine package and that may not have been decided yet.
