Polaris Dawn crew gears up for Thursday spacewalk
Billionaire Jared Isaacman and SpaceX crew trainer Sarah Gillis prepared to open the forward hatch of their Polaris Dawn spacecraft early Thursday to take turns floating outside in the first non-government spacewalk in the history of space exploration. Depressurizing the spacecraft will begin around 2:23 a.m. EDT (0623 UTC) and a scaffold-like “Skywalker” assembly extending just above the hatch will be used for stability.
