I wrote about NASA unveiling an inflatable Lunar habitat back in November, but never did locate more info on it until now. Honestly, I kind of forgot about it and did not really try very hard to find more info after the press release and just stumbled across a new article about the habitat today. This inflatable structure is one of the prototypes to possibly used on a space mission to the moon, which NASA wants to do again before 2020. It is being tested in Antarctica to see how it stands up to extreme conditions. They plan to decide by 2012 if this is a viable shelter option.
