Polaris Dawn

Polaris Dawn reached an altitude of 1,400 km - the farthest any crewed spacecraft had ventured from Earth since the Apollo program. Over five days in orbit, Jared Isaacman and Sarah Gillis performed the first commercial spacewalk; because Crew Dragon has no airlock, the entire cabin was depressurized for the EVA while the two partially exited through the hatch. At 30, Gillis became the youngest spacewalker to that point. The mission also served as the first in-orbit test of Crew Dragon's laser-based Starlink communications link.

Polaris Dawn was the first of three planned Polaris Program missions - a second Crew Dragon flight followed by the first crewed Starship mission.
