SpaceX Polaris Dawn Mission: Tech billionaire returns to Earth after first private spacewalk

A billionaire spacewalker, Jared Isaacman, returned to Earth with his crew after a five-day mission that took them higher than anyone since NASA's moonwalkers. SpaceX's capsule splashed down in the Gulf of Mexico. The mission included the first private spacewalk and tested new spacesuit technology for future Mars missions. This was Isaacman's second flight with SpaceX under his Polaris program.
