First off, I'd love to see some follow on studies to see how well women adapt to long term weightlessness. Shannon Lucid stayed up in Mir for months and seemed to suffer no ill effects. In fact, she appeared in better shape than a lot of men who spent the same time in space. Now that we have the ISS, this would be a good time to perform the studies.

Still, and not to sound too sexist, I wonder how well a group of women would work together couped up in a spacecraft for two years. My wife says she much prefers working with men than women. She says women engage in too much back stabbing and cat fights for her taste. I've seen how some female co-workers tear each other down from time to time. It isn't pretty. Men can argue all the way up to a fist fight then go out for beers afterwards.
