Two of Polaris Dawn’s four astronauts could make history today by performing the first ever commercial spacewalk at around 700 kilometers (435 miles) above our planet. Jared Isaacman, the mission leader and funder, and SpaceX engineer Sarah Gillis will leave the confines and safety of the Crew Dragon capsule for 15 and 20 minutes each. The other two crew members, Scott Poteet and Anna Menon, will stay inside the vehicle to monitor the spacewalkers’ status and make sure everything’s in order. SpaceX will stream the event live on its website and on X starting at 4:50AM Eastern time. In case the spacewalk has to be called off, the astronauts will have another opportunity on September 13 at the same time.
