EVAs without detailed rehearsals in the NBL are actually pretty common nowadays. That’s mostly down to the nature of Station operations. They’re no longer assembling it, carrying out complex, highly orchestrated operations on a tight timetable. Instead, they’re in a maintenance mode, so while some EVAs are expected

Yeah, that chestnut gets trotted out a lot. It’s risky, to be sure, but not as risky as people think. It’s not “instant DEATH!!!!” It’s mostly an elevated cancer risk.

Two Starliner missions (OFT-1 and OFT-2) have already survived reentry; I don’t see any new reason to worry about that part.

Extra bonus!

It’s broadly like removing the transmission from a Waymo, putting the parts into the Waymo’s passenger seat, and then asking it to drive to the nearest service station to find out what’s wrong. While Starliner has a lot of redundancy in the thrusters, the system is all interconnected. I doubt you could remove the

As far as the last paragraph goes, I think the people you should be least concerned about are Williams and Wilmore, although I’m sure they’re very frustrated about not being able to complete their mission. They had additional maneuvers they were going to perform post-undocking, and now they will never get to do those.

Oh, it would be so nice if they could do that. And if they could, Boeing would go for it in a heartbeat, actually. NASA would be ordering them to right now. Unfortunately, it’s not an option, for several reasons.

The lower pressure does indeed make it safer. What your lungs require (and what affects fire risk) is not the absolute pressure of the air but the partial pressure of the oxygen. At sea level, that’s roughly 5 PSI.  What you need to live, and what causes fire risk, really doesn’t change much depending on how much

OK, that makes a lot more sense. Thank you! They’re just going closer to an Apollo capsule environment prior to the EVA.

45 hours???? At first, I didn’t think this was so crazy. I mean, this is how the Gemini and Apollo spacewalks were done. (Including the batshit crazy spacewalk during the transearth cruise to retrieve film canisters from the Apollo service module. I mean, intellectually, I know it was really no more deadly than any of

Well, it’s not exactly SOP, since SOP is to avoid this situation if at all possible. NASA has tried very hard to avoid a shirtsleeves return for a long time. But I do agree that’s probably what they’ll have to resort to, since I believe the Dragon suits are custom fit.

That’s not the problem. The suits most definitely can fit through the hatch. The problem is they’re essentially useless on board Dragon, so there’s really no point bringing them out of Starliner at all. You might as well just go down in shirtsleeves, which is likely what they’ll have to do if they abandon Starliner. Th

BTW, just a random factoid you might be interested: back when the Commercial Crew contracts were being competed, one of the long-shot contenders was United Space Alliance. They actually did submit a proposal to continue operating the Space Shuttles. The killer (other than the huge operating cost - the program cost

Cynically, I do think you’re often right. DEI initiatives frequently exist primarily to be the equivalent of a company’s black friend. They’re great for reports, for marketing, for statements on websites, and so forth because they neatly lump all of the nice friendly “we care about people” stuff in one convenient

WOW. I just wish I could say I was surprised that happened.

That might be a worthwhile thing to explore, although I’m not sure how feasible it is. I don’t have any detailed insight into either suit beyond what we can see in the pictures, but they do appears to be shaped a little differently — enough that there could possibly be couch fit issues, which could possibly lead to

FYI: in this case, “they” is Futurism, not NASA or Boeing. And they do have a point. You get what you pay for.

They’re custom fit, apparently, just like the Sokol suits used on Soyuz.

You can’t just rebuild the Space Shuttles from blue prints. At this point, you wouldn’t even be able to pull them out of the museums and refly them. There are too many items in the supply chain that can no longer be manufactured. The effort would be gargantuan, and essentially equivalent to designing a new spacecraft.

Correct. Neither Boeing nor SpaceX could have designed their spacecraft to use the other’s suits, given the way this is structured. That would have been true no matter who had won. (Note: the same circumstance exists with Soyuz, and existed with the Space Shuttle, so it’s a little puzzling that this is surprising any
