Saw this article on Space.com that stated that NASA was looking at beginning human 100-day class missions in the 2006-2011 timeframe. Such talk seems to have O'Keefe's blessing, this seems to be a positive development. I haven't heard of top NASA officials talk of going back to the moon for years,but it's still low-key talk. This also marks the first time I've heard of a direction for NASA after the ISS is complete since O'Keefe's been administrator. Well, they really didn't use the "M" word, they just talked of 100-day class missions.

Here's the article:

A Sneak Peek at NASA's Plans for Exploring Mars and Beyond

A 100-day mission that didn't involve orbiting the moon would possibly mean going farther out than the moon and coming back in one orbit. They could make a larger number of smaller orbits, but one orbit that went beyond the moon would be a lot farther than NASA has sent a crew before. It would be a boring trip in the middle, with great interest at the beginning and the end.
