Looks like NASA wants to add more zing to its futuristic Z-series spacesuits, because the agency just revealed three far-out outer shell designs for the newest prototype. The new model (called the Z-2) is a follow-up to NASAs Buzz Lightyear-esque Z-1 spacesuit prototype, which was named one of Time Magazines Best Inventions of 2012. There are several differences between the two, including the quality of their upper torsos: while the Z-1s is soft, the Z-2s is hard and impact resistant.
