Tech billionaire Jared Isaacman completed the first private spacewalk on Thursday, emerging from a SpaceX capsule 460 miles above Earth.

This marks a significant milestone in commercial spaceflight, previously limited to professional astronauts.

Isaacman, testing SpaceX’s new spacesuits, performed the spacewalk briefly, lasting less than two hours. SpaceX engineer Sarah Gillis also conducted a brief spacewalk.

The mission, part of Isaacman’s Polaris program, was designed to test new equipment and capabilities for future space exploration, the Associated Press has reported.

This achievement is seen as a major advancement in the commercial space industry.
