close video WATCH LIVE: SpaceX crew attempt first civilian spacewalk in history
All four will face the vacuum of space, relying on untested SpaceX suits in the firstand possibly riskiestcivilian spacewalk in history.
Jared Isaacman, CEO of Shift4 integrated payment processing solutions, participated in the first ever private spacewalk by a group of astronauts who left a SpaceX capsule after a delay of a few hours, testing a new line of spacesuits in the company's riskiest mission yet.
Along with the billionaire entrepreneur is a retired military fighter pilot and two SpaceX employees. The four have been orbiting Earth aboard Crew Dragon since Tuesday's pre-dawn launch from Florida of the Polaris Dawn mission.
Isaacman "egressed Dragon" and conducted his first "suit mobility tests that will test overall hand body control, vertical movement with Skywalker, and foot restraint," according to a SpaceX post on X at 6:53 a.m.
"Back at home, we all have a lot of work to do, but from here, work sure looks like a perfect world," Isaacman said during his first views outside the Dragon. Minutes later, he said "it's gorgeous."

The mission is the Elon Musk-led company's latest and riskiest bid to push the boundaries of commercial spaceflight.
The capsule, at an altitude of 435 miles, was completely depressurized, and the whole crew relied on their slim, SpaceX-developed spacesuits for oxygen.

Isaacman, 41, is bankrolling the Polaris mission, as he did his Inspiration4 flight with SpaceX in 2021.
The billionaire Isaacman, who is also a pilot, has declined to say how much he is paying for the missions, but they are likely to cost hundreds of millions of dollars, based on Crew Dragon's price of roughly $55 million a seat for other flights.

The others in Polaris include mission pilot Scott Poteet, 50, a retired U.S. Air Force lieutenant colonel, and SpaceX employees Sarah Gillis, 30, and Anna Menon, 38, both senior engineers. Gillis also conducted a spacewalk after Isaacman completed his turn outside the capsule.
