For those of you interested in a broad overview of the cutting edge of space exploration, or just in need of a space excitement boost:

Mason Peck, the NASA Chief Technologist (who also happens to be my PhD advisor) did an AMA on Reddit yesterday.  He answers a swath of questions about the future of space exploration – both near and far term; public and private; crazy and … slightly less crazy.

The full thread (includes some good discussion and reference links)

 If you understandably wish to avoid Internet discussions, here’s a compilation of just the questions and direct answers. 

My personal favorite comment: ‘"Mason Peck" is an anagram of "Space Monk." Is nobody else suspicious here.’
