Well, it's been 2 years since my Zero-G flight, and my body still remembers it intimately. As I noted in my LCR/SFF notes at Selenian Boondocks, when we went to see the Cirque de Soleil show Kà I was having flashbacks to micro-g during one of the acrobatic routines. A serious flashback that gave me a bad jones for freefall. Even right now I can clearly remember that first moment when I started floating up off the floor.

And yes there should be spacewalking. In an old post somewhere where I considered the selling off of the Columbia space shuttle (RIP), one point I noted was that since NASA's not using the EMUs or MMUs or whatever the specific acronym was for the jetpacks, then they should be included in the purchase of the shuttle to allow tethered EVAs during the trip.

I think the memory lies in the nature of the experience. Something that's really fun or touches you in a profound way (or just really ticks you off) is much more likely to get seared into memory, while the average trip is discarded except for important bits and pieces.

The guys that are going to work in space are probably going to end up watching videos and playing games during the transport function. Once an infrastructure is developed it's likely going to be a week each way to the Moon, at least until we get nuclear. That's how long it used to take the old props to cross the Pacific to Asia. Better stock up on some rad-hard PS2 games.
