Rick Tumlinson, founder of the Space Frontier Foundation and Jonathan Clark, a former NASA flight surgeon whose wife, astronaut Laurel Clark, died in the space shuttle Columbia disaster in 2003, are behind it all. They are designing a suit that can withstand extreme environments---from the airless chill of space to the burning heat of reentry. Indeed, this daredevil spacesuit might just as well be Iron Man's costume.
A new sport called spacediving is envisioned to become popular once commercial flights into space become commonplace. The developers say it will be the ultimate extreme sport.
