The SpaceX Polaris mission launched on Tuesday, September 10, marking a historic milestone with the first-ever commercial spacewalk involving four civilian crew members.

The launch of the SpaceX Polaris mission, which took place on Tuesday, September 10, drew considerable attention. Aboard the capsule were four civilians: CEO of Shift4 Payments Jared Isaacman , SpaceX engineers Anna Menon and Sarah Gillis , and former U.S. Air Force pilot Scott Poteet . They aimed to make history by conducting the first commercial spacewalk. With the mission successfully completed in the early hours, many have since wondered how they can watch a replay of the spacewalk.

NASA Administrator Bill Nelson celebrated the achievement on X , posting, “Congratulations @PolarisProgram and @SpaceX on the first commercial spacewalk in history! Today’s success represents a giant leap forward for the commercial space industry and @NASA’s long-term goal to build a vibrant U.S. space economy.”

Why Was the Polaris Mission Conducted?

According to the Polaris Program website, the mission aims to “support scientific research designed to advance both human health on Earth and our understanding of human health during future long-duration spaceflights and be the first to test Starlink laser-based communications in space.”

The crew will spend five days in space before returning on Sunday, September 15.
