a whole lotta videos (http://link.brightcove.com/services/player/bcpid537086541) on this site
A handful of simple talks, but mostly a lot of complicated technical talks that explain why an asteroid "2004 MN4" in 2029 (or 2035/2036) might (but probably won't) impact the earth, as wel as longer-term visions some folks have for future exploration and lunar colonization... some really neat stuff. Fun to watch Buzz Aldrin warning us to get back on the moon before China beats "us" to it :) ... at the very least, the current ENERGY crisis needs a solution beyond just "build more solar panels and wind collectors" -- apparently "H3" Helium (http://en.wikipedia.org/wiki/Helium-3#Power_generation) might be that solution (see the last video, "Harrison Schmitt (http://en.wikipedia.org/wiki/Harrison_Schmitt#Post-NASA_career) - Helium Fusion", 12 mins long).
Rather than a return to the moon I think we need to check out some asteroids, if anything will spark commercialism in space it's gonna be gold in them thar hills.
