At 3:38AM ET, SpaceX confirmed the successful conclusion of its historic Polaris Dawn mission, which took four people, including Billionaire Jared Isaacman and SpaceX engineer Sarah Gillis, farther into space than any astronaut has been in decades.

During the flight, Isaacman and Gillis became the first private astronauts to conduct a spacewalk. Gillis also recorded herself playing violin while in space, as Engadget notes.
