Meet the 4 astronauts who will be on SpaceX's high-risk Polaris Dawn mission
Briefly

SpaceX's Polaris Dawn mission is set to perform the first privately managed spacewalk, a groundbreaking attempt that marks a new chapter in commercial space exploration.
The mission will demonstrate SpaceX's newly developed spacesuits and their viability for human survival outside of the Crew Dragon capsule, lacking an airlock.
Jared Isaacman, the mission commander and CEO of Shift4 Payments, is financing Polaris Dawn, estimated to cost hundreds of millions, but specific figures remain undisclosed.
Scheduled for launch at 3:38 a.m. ET on Aug. 27, the six-day mission also includes an ambitious plan for a spacewalk on its third day.
