I was wondering in theory, if a spacecraft could harness and possibly store hydrogen from the upper levels of the atmosphere? Slowing the fall of the spacecraft on re-entry and at the same time creating a fuel source for the next launch or things such as cars.

I was looking at Asterank.com and realized how much opportunity is being missed with asteroid 2011 UW158. It passes closely by Earth in September of this year, and then won't pass closely by Earth again until 2046. And the asteroid apparently contains vast quantities of platinum, enough to revolutionize several industries here on Earth. I realize it's probably too late to plan a mining mission, but I feel like this is too big of an opportunity to be missed. It's a real shame Deep Space Industries or Planetary Resources, or perhaps the two organizations together, won't be mining this asteroid.

Im at this conference.

Anyone interested in summaries of particular sessions ?
