on september 12, beijing time, the "polaris dawn" mission carried out the first commercial spacewalk by humans. at around 18:50, jared isaacman, the founder and ceo of the payment processing company shift4 and an american billionaire, opened the hatch, and applause and cheers were heard from the ground from time to time. isaacman stayed in the vacuum of space for about 10 minutes. after returning to the cabin, at around 19:05, astronaut sarah gillis walked out of the hatch.

on september 10, isaacman and four other private astronauts boarded the spacex crew dragon spacecraft launched by the falcon 9 rocket at the kennedy space center in florida to carry out the first mission "polaris dawn". the other three people accompanying him were retired air force lieutenant colonel and fighter pilot scott "kidd" poteet and two spacex employees, including mission specialist sarah gillis and mission specialist and medical officer anna menon.

isaacman and gillis will each exit the spacecraft and perform a series of spacesuit mobility tests. because spacex's spacesuits do not include a primary life support system that would allow astronauts to float more freely in space and perform complex tasks, the astronauts of the polaris dawn will receive life support from long hoses connected to the spacecraft.
