The launch of Polaris Dawn is scheduled for tomorrow, August 28th. The launch window will open at 3:38am EDT and go up to around 7am. The orbital inclination will be of 51.6 degrees, same as the ISS.

The crew members are

Commander: Jared Isaacman

Pilot: Scott Poteet

Mission Specialist 1: Sarah Gillis

Mission Specialist 2: Anna Menon

Both Gillis and Menon work for SpaceX.

This mission is privately founded by Isaacman and possibly SpaceX as well. It was first announced in 2022 and will include a spacewalk testing the experimental EVA suits made by SpaceX.

Upon launch the crew Dragon Resilience will be placed on an elliptical 190x1200km orbit, after a series of checks Resilience will rise to an apogee of 1,400 km, the highest ever for a non-lunar mission and surpassing the previous apogee record held by Gemini 11 (1,368 km).

On day 2 they will go lower into an 190x750km orbit in preparation for the EVA. On day 3 the cabin will be depressurized, after the hatch is opened both Isaacman and Gillis will leave the vehicle while connected by ropes while Menon and Poteet remain inside the cabin while also being exposed to the vacuum. On day 4 they will test Starlink communications. Re-entry preparations will take place on day 5.
