As a result of the success of zero- and partial-gravity testing on the KC-135 Vomit Comet and in 1g field tests in Arizona and at Johnson Space Center, the EVA Project Office at Johnson Space Center is currently looking toward a soft suit design for future astronauts that incorporates the enhanced mobility features of the Mark III, but with a lower weight penalty.
