Polaris Dawn is finally headed to space for its groundbreaking civilian mission

A SpaceX Dragon capsule carrying the four private astronauts of the Polaris Dawn mission has launched from the Kennedy Space Center in Florida in the early hours of September 10 after a few weeks of delays. The mission was scheduled to lift off at the end of August but was postponed first due to technical issues, then because of poor weather conditions forecasted for the crew’s return. On board are Jared Isaacman — the billionaire who funded the mission — retired Air Force Lieutenant Colonel Scott “Kidd” Poteet, and SpaceX engineers Sarah Gillis and Anna Menon. They’ll attempt several firsts during the five-day flight, including the first-ever commercial spacewalk.

That attempt will also mark the first spacewalk from a Dragon capsule. Among Polaris Dawn’s other goals is to send its crew farther than anyone has traveled since the Apollo program, targeting an altitude of about 870 miles from Earth. The journey will take the capsule and its crew briefly into the Van Allen radiation belt.

Polaris Dawn is meant to be the first of three human spaceflight missions under Isaacman’s Polaris Program. Its crew will put SpaceX’s new Extravehicular Activity space suit to its most important test yet, as they’ll all wear it for protection against the vacuum of space when the Dragon’s doors open for the spacewalk. The spacewalk will take place at an elliptical orbit roughly 435 miles above Earth’s surface, and two crew members will leave the capsule.
