I believe that the market price Russia set for ferrying crew members from other countries up and down from the ISS was $86 million per seat. I suspect that at that rate SpaceX could have a Crew Dragon on the pad pretty quickly and turn a tidy profit.
Well, I'm using also NK's information and Katya's translation But I agree the information at hand is incomplete, and so it's currently impossible to tell with certainty.

But suits are also customized for the individual crew member, so I really hope they can be built from measurements and do not need to be physically fitted to the crew member.
Far as I know the "customized and fitted to each crew member" is mostly for fit and comfort and not operations or safety. In other words a crew member could use a suit designed for a slightly larger person and still be ok. Obviously if it's too big and you are swimming around inside the helmet or your gloves are two sizes too big and you can't press a button, it would be an issue.If they need to substitute Dragon I don't think the crew wearing suits that didn't fit perfectly would be a show stopper.Quote from: DanClemmensen on 12/15/2022 11:33 amQuote from: AJW on 12/15/2022 06:43 amI believe that the market price Russia set for ferrying crew members from other countries up and down from the ISS was $86 million per seat.

technical liquid
external casing of the... instrumentation and equipment compartment was damaged
Certainly Prokopiev is having bad luck with his Soyuzes. Remember than on his first flight (Soyuz MS-09) there was a problem on his orbital module, with a hole discovered in orbit that led to an EVA to inspect it.

IIRC, they had to scrape away the insulation of the Soyuz-MS 09 spacecraft to examine the hole.
The coolant leak on the Soyuz MS-22 spacecraft was never controlled, it just stopped leaking last night after all of the coolant was gone. Russian specialists are now assessing impacts on other Soyuz systems to determine whether the craft is flyable.

Anyway, since there's the most likely chance of Soyuz-MS 23 launching uncrewed to take Prokopyev, Petelin, and Rubio home; MS-22 will undock automatically and deorbit itself, right?

Is MS-22 unsafe for crew? Can it undock and retreat away safely, crewed or not?As for timing, after the MS-10 abort, they were able to move the next launch ahead by 17 days. That number might improve if they can just say MMOD and not have to do a commonality investigation.

That number might improve if they can just say MMOD and not have to do a commonality investigation.The statement linked earlier seems to rule out MS-22 for crew transport, if the coolant loop is confirmed as inoperable, but also may be slowly becoming a hazard by itself, due to incremental risk of components overheating and failing.“If all the coolant is gone, the ship will have to be kept in the shade from the Sun. And it will need to be replaced as soon as possible, the better. Overheating of individual elements can cause other accidents, so keeping such a device in orbit is risky”Of course, the bolded part is what they're assessing right now, but does seem like a safe bet. It also appears the PAO coolant circuit is NOT redundant, contrary to ealier speculations - not sure whether this is confirmed.Under this scenario, it may need to be deorbited, or at least undocked and drifted away from ISS before it becomes impossible to do so, as soon as practicable. However, it may not be possible to fast-track the launch of MS-23 by that much, leaving ISS without lifeboat capability for half of its crew for an extended time.

NASA is going to use the Candadarm2 (a large robotic arm) to survey the Soyuz vehicle and try to pinpoint the damage location. This will help determine the extent of damage as well as possibly its cause, i.e. micrometeoroid debris. An international effort!
The statements you quoted and bolded are speculation from an outside expert, not from Roscosmos.Wasn't it mentioned in earlier posts that Soyuz has redundant cooling loops (and likely only one loop failed)? Edit: I see that you did mention that you think the loop is not redundant, but is that based on the speculation from the outsider, or based on any official info?
