SpaceX Crew Makes History with First ‘Stand-Up’ Private Spacewalk During Polaris Dawn Mission

SpaceX made history today when its private astronauts conducted the first-ever private spacewalk as part of the Polaris Dawn mission.

As SpaceX's Crew Dragon spacecraft orbited Earth at an altitude of about 740 km at a speed of more than 25,000 km per hour, the two astronauts partially ejected from the spacecraft, one at a time.

The four-man crew began evacuating the cabin at 10:31 GMT, eventually manually opening the hatch at approximately 10:50 GMT. All crew members were wearing new SpaceX spacesuits that have been thoroughly tested on Earth but not in orbit.

Jared Isaacman, the mission commander, head of SpaceX's Polaris program and billionaire co-financier, was the first person to step out of the spacecraft and look down at Earth. “It certainly is a perfect world from up here,” Isaacman said, lifting his head and torso from the capsule.

Isaacman then went through a series of suit mobility and safety checks before returning to his seat in the spacecraft a few minutes later, after which Crew Dragon fired its thrusters to maintain an optimal orbit and SpaceX engineer Sarah Gillis performed a spacewalk.

Neither Isaacman nor Gillis fully exited the spacecraft, making the event technically a stand-up extravehicular activity (SEVA) rather than a full spacewalk. Previous SpaceX promotional materials for the mission stated: Astronauts completely exit the capsule.

While all previous spacewalks to date have been conducted by government-trained astronauts, the Polaris Dawn crew will be all civilians: along with Isaacman and Gillis are retired U.S. Air Force test pilot Scott Poteet and SpaceX engineer Anna Menon.

Isaacman also took part in SpaceX's groundbreaking flight in 2021, which was the first orbital spaceflight with only private citizens on board. That flight used the exact same Crew Dragon spacecraft as the latest mission.

SpaceX's Polaris Dawn mission is reminiscent of earlier space programs of the 1960s and 1970s because the Crew Dragon capsule does not have an airlock, making it one of the most dangerous spacewalks ever attempted.

Once SEVA is complete, the remainder of the mission will see the crew spend up to two more days in orbit before returning to Earth.
