Now if this cools the service module and it looses all cooling things can get bad so bad IIS might have to drop it, if it has some redundancy they are likely good. Its also some chance they don't want to risk crew on it, we has to wait for diagnostic. Its cooling system presumes several (at least two) days of autonomous flight, while the deorbit takes a couple of orbits. So, it's probably enough even passive cooling. Currently it's attached to the station, so unlikely is heated much. Quote Link to comment Share on other sites More sharing options...

steve9728 Posted December 16, 2022 Share Posted December 16, 2022 I think there's another set of Soyuz in the assembling plant now, isn't it? Spoiler Honestly, I can't fully understand why CNSA would keep a back-up Shenzhou and CZ-2F in the VAB for "emergency rescue" since the launch of the CSS's core module: I always thought if something really bad had happened and the emergency launch preparation procedure within a week might be too late. Until this time... Quote Link to comment Share on other sites More sharing options...

How hot can it get before other subsystems start taking unacceptable damage? And how hot can it realistically become in there? Quote Link to comment Share on other sites More sharing options...

ra4nd0m Posted December 16, 2022 Share Posted December 16, 2022 (edited) If I remeber correctly the Soyuz have two separate cooling loops. One for equipment, another for life support. If it is really so hot inside, then LS radiator is to blame. I wonder is it possible to just vent the atmosphere 'cause vacuum is a prefect insualator and equipment cooling system is NOT damaged and return to Earth like this. Quite a Kerbal way but why not.

If the heat can't be absorbed by the atmosphere, it will accumulate. Eventually things will start melting. Quote Link to comment Share on other sites More sharing options...

Eventually things will start melting. Every modern ship is designed to survive loss of atmo. All important equipment is usually hooked onto a different cooling loop (at least in Soyuz). So nothing is going to melt while heat accumulation will slow down. Quote Link to comment Share on other sites More sharing options...
