Mission info

Polaris Dawn is a crew mission aboard a SpaceX Crew Dragon Spacecraft. The Polaris Dawn crew (Commander Jared Isaacman, Pilot Scott Poteet, and Mission Specialists Sarah Gillis and Anna Menon) will spend up to five days in orbit, flying higher than any Dragon mission to date and will attempt to reach the highest Earth orbit flown since the Apollo program. The Polaris Dawn crew will support scientific research designed to advance both human health on Earth and our understanding of human health during future long-duration spaceflight, be the first to test Starlink laser-based communications in space, and will attempt the first spacewalk from a Dragon Spacecraft.

They're going to be up there a while in that little shuttle!

How long has it been since a capsule/spaceship has been depressurized for a spacewalk?

[–] threelonmusketeers@sh.itjust.works 7 points 1 month ago* (last edited 1 month ago)

It's been a while. I don't think Soyuz and ~~Shenzhou~~ have ever supported EVAs. The Space Shuttle did, but it had an airlock. The last spaceship depressurization for a spacewalk might not have been since the Gemini days back in the '60s.

Edit: Shenzhou 7 did include a spacewalk, but it seems like they used the orbital module as a pseudo-airlock, and never depressurized the descent module. Wikipedia has a nice list of spacewalks.

Dragon separation confirmed!
