A pioneering private crew made history by performing the first commercial spacewalk as part of the SpaceX Polaris Dawn mission.

The mission, led by Jared Isaacman, launched from the Kennedy Space Center in Florida and reached an altitude of 434 miles.

The crew's extravehicular activity began with Isaacman opening the hatch and exiting the Dragon spacecraft, which lacked an airlock, exposing all crew members to the vacuum of space.

NASA's Bill Nelson noted that this event signifies a major milestone for the commercial space industry.

The mission's tasks included testing the new SpaceX suits and satellite communications, and it is the first of three missions under the Polaris program, a collaboration between Isaacman and SpaceX.
