Polaris Dawn astronauts successfully perform the first commercial spacewalk

Polaris Dawn astronauts Jared Isaacman and Sarah Gillis have successfully exited the confines of their Crew Dragon vehicle to perform the first ever commercial spacewalk on September 12. SpaceX and the Polaris crew started preparing for the event at 6:01AM Eastern time, checking that all their gear was in order and putting on the SpaceX extravehicular activity (EVA) suits that all four of them have to wear, because opening the Dragon’s hatch will expose them to outer space. Pure oxygen was pumped into the suits to check for leaks before all the air was let out of the vehicle and before Isaacman opened the hatch.

A few minutes before 7AM Eastern, Isaacman went through the hatch and exited the vehicle, with the Dragon’s camera capturing his silhouette against our planet as the backdrop. He then performed a series of mobility exercises as planned — the whole point of the spacewalk was to test SpaceX’s new EVA suits — before going back into the capsule. “Back at home, we all have a lot of work to do,” he said as he emerged from the vehicle. “But from here, it looks like a perfect world.”

After he went back to his seat, SpaceX engineer Sarah Gillis geared up for her turn. She had to deal with the hatch seal bulging out a bit, but she was ultimately able to climb out of the hatch and do a series of mobility exercises like Isaacman did. Once she was done, the team closed the hatch and started repressurizing Dragon to equalize the atmosphere inside before checking the cabin for any leaks. By 7:55AM, Dragon’s repressurization was complete, marking the completion of today’s spacewalk.
