I think that we should launch Mr. Chang-Diaz along with his trusty drive, so that he'll have his 8th flight into space. Right now, he'd tied for the top spot in flights into space, and I hope that he'll get to break that tie, right quick. Maybe he can later tie a VASIMR onto a Bigelow hotel / module, and boost that stack into lunar orbit. I doubt if he wants to wait in the maid's quarters for the first guests to arrive afterward.
