Until we find a faster mode of transportation or a better way to stay conditioned, we aren’t going anywhere. Watch astronauts coming back to Earth after 6 months in the space station, they can’t walk. Imagine two years in space in a very confined area, probably in some light sleep a lot of the time just to pass the time. Muscle atrophy of up to 20% was noted in flights lasting only a week or two. I’d guess it looks like a one way trip. Now that might be something to consider. A colony on Mars supplied by unmanned craft until somebody like “O” decides you are too expensive and aren’t returning on the investment. Let’s see, everyone watched as Apollo 11 and no one was watching Apollo 13. Hard to imagine we’d keep our interest after a year or two of the same broadcast antics from Mars.
This is ground control to Major Tom.....
Kevin, what do you think of Aldrin’s statement?
