Polaris Dawn crew gears up for first commercial, non-government spacewalk

Billionaire Jared Isaacman and SpaceX crew trainer Sarah Gillis are planning the first non-government spacewalk in space exploration history. They will open the forward hatch of their Polaris Dawn spacecraft to float outside using a scaffold-like assembly for stability. The spacewalk will test the comfort and mobility of their pressurized suits and provide valuable data for future suit designs. The goal is to perfect low-cost spacesuits for commercial astronauts flying to the moon or Mars aboard SpaceX rockets. The mission, part of three planned by Isaacman in cooperation with SpaceX, is expected to last five days, ending with splashdown off the coast of Florida.
