Watch live! SpaceX’s historic Polaris Dawn spacewalk

Polaris Dawn will attempt its historic spacewalk on Thursday (Sept. 12) at 2:23 a.m. ET (0623 GMT), SpaceX wrote in a mission description on its website. During the spacewalk (also known as an extravehicular activity, or EVA), Polaris Dawn crewmembers Jared Isaacman and Sarah Gillis will exit their fully depressurized Crew Dragon spacecraft in specially-designed SpaceX spacesuits. It will be the first-ever spacewalk by private astronauts. You can watch it live here when the time comes, courtesy of SpaceX.
