The Crew Dragon spacecraft carrying four astronauts landed off the coast of Dry Tortugas, Florida (USA) at 3:37 a.m. on September 15, Eastern time (2:37 p.m. on September 15, Vietnam time).
The Polaris Dawn mission made history by reaching a higher altitude than any human flight in five decades. The crew’s spacewalk early on September 12 was also the first privately funded and operated spacewalk.

The return to Earth on this mission was also one of the more dangerous parts for the astronauts. The spacecraft reached extremely high temperatures, up to 1,900 degrees Celsius, due to the pressure and friction caused by hitting the air while still traveling at about 27,000 km/h. The vehicle began to slow down before deploying a parachute to further slow its descent.
After reaching the ocean, the spacecraft was loaded onto a special boat by a rescue team waiting nearby. Final safety checks were carried out there before the crew left the capsule and began the journey back to land.

The Polaris Dawn crew includes mission commander Jared Isaacman, CEO of financial services company Shift4 Payments; former US Air Force pilot Scott “Kidd” Poteet; and SpaceX operations engineers Anna Menon and Sarah Gillis.
Their mission broke altitude records, reaching an orbit around Earth of 1,400 km. It was the highest Earth orbit humans had ever reached since the last Apollo moon mission in 1972.
After breaking the altitude record, the Crew Dragon descended for the spacewalk. Isaacman and Gillis exited the capsule for about 10 minutes, performed a series of tests to understand the functionality of their EVA spacesuits, then retreated back into the capsule and latched the hatch. The spacewalk went off without any major problems.
