NASA still working on long-term plans for ISS seat barters - SpaceNews
As NASA prepares to launch another commercial crew mission with a Russian cosmonaut on board, it has yet to work out an agreement on future crew swaps.

NASA hits limits of space station utilization - SpaceNews
NASA has effectively reached full utilization of the International Space Station given limitations on crew time and the ability to get cargo to and from it.

International Space Station Operations Update, Crew Continues Normal Activities
Earlier today, Feb. 11, the uncrewed Roscosmos Progress 83 cargo spacecraft docked automatically to the aft end of the Zvezda service module at the

This is very strange. We were told that the recent Soyuz coolant leak was due to a micrometeorite impact. Now a Progress vehicle that has been docked at the ISS for several weeks (?) has lost all its coolant.
It seems extremely that the Progress leak was also due to a micrometeorite; what are the odds of two micrometeorite strikes hitting within a few weeks of each other and both causing a coolant leak and no other apparent damage?
My guess is that both leaks are due to a mechanical defect and not due to micrometeorites.

Eric Berger on the Progress leak:
In my opinion, Roscosmos probably lied about the cause of the Soyuz leak.
Russia delays uncrewed Soyuz launch to investigate Progress leak
Russia has delayed the launch of an uncrewed Soyuz spacecraft to the International Space Station to investigate damage to a second spacecraft there.

To my completely untrained eye, the photo Roscosmos released do seem to support their statement that the Soyuz coolant leak was caused by an external impact. But it boggles the mind to think that an external impact also is responsible for the Progress coolant leak. What are the odds?
My eye is equally untrained- maybe a coolant leak through poor design or fatigue look exactly like that from the outside
It looks like a very small hole that caused a leak to me. A micrometeorite could cause something like that. JMHO.

Appreciate that this is intended as a dig...but:
Definitely not design. Soyuz (the space vehicle in this case) has been around pretty much since space was invented. In fact I wouldn't be surprised if the last major cooling system architecture sure overhaul was 40-50 years ago.
Fatigue is unlikely as well, as there's not really a material number of cycles put on anything in Soyuz.
If its self inflicted damage (so, not a micrometeorite), it's likely the result of workmanship. For years now the Russian space program has suffered from budget cuts and corollary short cuts up and down the supply chain. For instance, there could be some component inside that exploded [ostensibly as a result of just high pressure rather than actual combustion] in such a way that the shrapnel poked a single small hole through the skin on the way out.

Russia commits to ISS extension to 2028
The Russian government has agreed to continue participation in the International Space Station to at least 2028, the last partner to agree to an extension.

A bit surprising, but a tacit acknowledgement by Russia that without the ISS they won’t have a presence in space. Russia’s recent grandiose announcement about building their own space station is just vaporware.Russia commits to ISS extension to 2028

Livestream of two astronauts on an EVA to install a new rollout solar array that was recently delivered to the ISS by a Cargo Dragon mission. Pretty amazing to watch.
Hmm, I think that is the EVA from two weeks ago:

Oops.
I saw “Live” and made an incorrect assumption. Oh well, it’s still cool to watch.
Russian ISS module experiences coolant leak
A radiator on the Russian segment of the International Space Station started leaking coolant Oct. 9, the third such incident in less than a year.
spacenews.com
Right. Micrometeoroids only cause a problem on the ISS when they impact Russian-built radiators. If they hit anywhere else, no problem!
And micrometeoroids have only hit Russian radiators in the past several months, never in the many years previously that the ISS has been in orbit.
Makes sense to me.
Scott Manley as always provides useful info and context on the new Russian radiator leak. No comment on why they seem to leak so often compared to the radiators on the US side.
