Polaris Dawn Spacewalk Overview: While traveling in an elliptical orbit of ~190 x 700 km around the Earth, the Polaris Dawn crew will complete a pre-breathe process, perform suited mobility tests and inspections, and initiate pressurization checkouts prior to performing a final suit leak check and committing to the spacewalk. Dragon’s cabin pressure will slowly lower to vacuum prior to hatch opening. Once opened, all four crewmembers will be exposed to the vacuum of space. Mission Commander Jared Isaacman (EV1) will exit Dragon, perform a series of mobility tests in the newly-designed SpaceX EVA suit, and return to Dragon’s cabin. Mission Specialist Sarah Gillis (EV2) will perform the same series of actions and, after re-entering Dragon, close the spacecraft’s hatch. Mission Pilot Kidd Poteet and Mission Specialist and Medical Officer Anna Menon will monitor vital support systems throughout the operation. After hatch closure, Dragon will slowly repressurize while oxygen and nitrogen levels return to normal. The entire spacewalk operation is expected to take approximately two hours. 00:00 EVA Begins 06:15 Hatch Opening 08:20 EVA 1 Jared Isaacman Exit 16:34 EVA 1 End 19:18 EVA 2 Sarah Gillis Exit 29:10 EVA 2 End 33:00 Hatch Close EVA Ends Video Credit: SpaceX Full EVA Live: Learn More: 1.
