SpaceX Polaris Dawn Crew Scripts History With First Ever Private Spacewalk | Video | Science

A tech billionaire Jared Isaacman performed the first private spacewalk hundreds of miles above Earth on Thursday, a high-risk endeavor reserved for professional astronauts — until now. Tech entrepreneur Jared Isaacman teamed up with SpaceX to test the company’s brand-new spacesuits on his chartered flight. The daring spacewalk also saw SpaceX engineer Sarah Gillis going out once Isaacman was safely back inside. This spacewalk was simple and quick — less than two hours — compared with the drawn-out affairs conducted by NASA. Astronauts at the International Space Station often need to move across the sprawling complex for repairs, always traveling in pairs and lugging gear. Station spacewalks can last seven to eight hours.
