Very solid @PolarisProgram training week. In addition to the sims, we spent a lot of time pressurized in the EVA suits working contingencies. Lots to get done, but it feels like momentum is building. Very grateful to the engineers & training team @SpaceX

Good questions:
- No airlock. Dragon will vent to vacuum and then cabin will repressurize post-EVA. As a result, all 4 crew members are technically performing an EVA.
- Suit pics will be released before the mission.
- Throughout development & training, we simulate microgravity through an offload system. Though, as a crew, we do love SCUBA.
- Yes, there is a documentary. Same doc crew as Inspiration4. I am hoping its really captures the story of all the badass SpaceX engineers that are developing the capabilities to make these objectives possible (very high apogee, EVA suit & operations, Starlink laserlink, science & research, etc).
- I am feeling more confident by the day on launch timing, but we will provide more updates soon.

Polaris Dawn seems like a pretty exciting mission! Really stretching the capabilities of Dragon.
I’m sure it’s reasonable, but I’m deeply unsettled by the thought that someone is going to press a “depressurize our entire spacecraft” button.
Excited for more details though!
One hopes that there’s more than a single button involved. Hopefully several, with flip-up plastic covers, and at least one manual valve.
This is not something we want to happen by accident
