Polaris Dawn is funded and led by billionaire Jared Isaacman, the founder of financial firm Shift4 Payments. SpaceX engineers Anna Menon and Sarah Gillis and retired US Air Force pilot Scott Poteet round out the crew of four.
A highlight of the mission will be their attempt to perform a spacewalk without an airlock. Opening the door of the Crew Dragon capsule will expose all four crew members to the vacuum of space. Only their spacesuits will keep them safe. Also, differences in pressure may make it difficult to relock the vehicle’s hatch. It's actually a daring maneuver, and we wish the crew good luck when they try it later this week.
