Will any science be conducted during the trip?
I just figure, while they're out there....
A little while back I posted a note about how some day rich space entrepreneurs could rebuild and re-enact both famous space flights and those that never came to be, such as the Soviet plans for manned lunar exploration. Looks like one aspect is coming true much sooner than I expected.
As for cramped quarters, if you can afford the price tag, a little less personal space than usual for a trip around the Moon seems a small price to pay.
