SpaceX Crew All Set For First Private Spacewalk, To Test New Spacesuits

Crew of the SpaceX Dragon capsule, two of whom will spacewalk on Thursday

The first private spacewalk is set for Thursday by a group of astronauts who will
leave a SpaceX capsule after a delay of a few hours, testing a new line of spacesuits in the company’s riskiest mission yet.

A billionaire entrepreneur, a retired military fighter pilot and two SpaceX employees have been orbiting Earth aboard Crew Dragon since Tuesday’s pre-dawn launch from Florida of the Polaris Dawn mission.

It is the Elon Musk-led company’s latest and riskiest bid to push the boundaries of commercial spaceflight.

Live streaming of the event is set to begin at 4:55 a.m. ET (0855 GMT), SpaceX said on Thursday, with two astronauts venturing outside Crew Dragon while two stay inside.

The capsule, at an altitude of 700 km (435 miles), will be completely depressurized, and the whole crew will rely on their slim, SpaceX-developed spacesuits for oxygen.

Jared Isaacman, 41, a pilot and the billionaire founder of electronic payments company Shift4, is bankrolling the Polaris mission, as he did his Inspiration4 flight with SpaceX
in 2021.

He 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.

Farthest Since Apollo

Throughout Wednesday the spacecraft circled Earth at least six times in an oval-shaped orbit as shallow as 190 km (118 miles) and stretching out as far as 1,400 km (870 miles), the farthest in space humans have traveled since the last U.S. Apollo mission in 1972.

The gumdrop-shaped spacecraft then began to lower its orbit into a peak 700-km (435-mile) position and adjust cabin pressure to ready for the spacewalk, formally called Extravehicular Activity (EVA), the Polaris program said on social media on
Wednesday.

“The crew also spent a few hours demonstrating the suit’s pressurized mobility, verifying positions and accessibility in microgravity along with preparing the cabin for the EVA,” it
said.

During the spacewalk, Isaacman and Gillis will exit the Crew Dragon tethered by an oxygen line while Poteet and Menon stay within.

Only government astronauts with several years of training have done spacewalks in the past.
