I don't think it does. But what's to stop the whole (limited) crew from suiting up (without MMUs), slowly venting the interior air, doing the EVA, then returning and re-pressurizing the atmosphere from interior tanks? My guess is it's just uncertified for that procedure, not that it's impossible. And there's no recourse if one of the suits fail.
- mikepurvis 5y agoThis is how it worked for all of the capsule-based missions— the entire cabin space is the airlock.
- rtkwe 5y agoCabins were also much simpler back then there's a lot more to break in a modern capsule compared to Mercury and Apollo. Actual toilets for starters.
- p_l 5y agoThere might also be not enough space to move with a full EVA suit - which is a wildly different thing from in-capsule survival suit.
