First-ever private spacewalk

Billionaire entrepreneur Jared Isaacman and SpaceX employee Sarah Gillis step out of the SpaceX Crew Dragon capsule for the first-ever private spacewalk. SpaceX's Crew Dragon craft will slowly depressurize its entire cabin - it has no airlock like the ISS - and all four astronauts will rely on their slimmed-down, SpaceX-built spacesuits for oxygen. For the spacewalk, Isaacman and Gillis will exit the spacecraft tethered by an oxygen line while Scott Poteet, a retired U.S. Air Force lieutenant colonel and SpaceX employee Anna Menon stay in the cabin.
