#NASA #ISS BREAKING from Bill Harwood of #CBSNews on Zombie Twitter:

*****

ISS: In the last few minutes, MCC-Houston asked the ISS crew to go to the cupola and look for any signs of "flakes" toward the aft of station; Jasmin Moghbeli reported "yeah, there's a leak coming from the radiator on MLM;" the MLM is the Russian Nauka multi-purpose lab module

#NASA #ISS Harwood then tweets:

ISS: Andreas Mogensen reports he's taken photos and sent them to the ground; no other information yet; the Russians suffered two recent coolant leaks, one on a Soyuz and another on a Progress cargo ship

#NASA #ISS This 2021 #ESA map shows you the relative locations of Nauka (Russian for science) and the cupola (viewport).

A leak from a radiator on the Russian Nauka laboratory module has been confirmed by the space station crew. NASA mission control has asked for the station's window shutters to be closed. You can listen to live audio in our Launch Pad Live Stream:

ISS: There are believed to be two radiators on the Nauka lab module, including one launched years ago with the Rassvet module and installed earlier this year during a Russian EVA; leak origin not yet known

ISS: MCC to Mogensen: "We're still assessing with Moscow. Right now there are no impacts, still working to fully understand this one"

#NASA #ISS Live station audio with an external view (not of the leak) streaming live on the NASA YouTube channel:

#MASA #ISS I've heard a couple "caution and warnings" on the space to ground between station and Houston, but both times Mission Control nothing to worry about, "we're looking at it."

#NASA #ISS A random reminder from #StarTrek that coolant leaks are not a good thing ...

#NASA #ISS The space to ground audio has been quiet, but the station has many different means of communication with the ground, and not just to Houston. There are mission controls at Star City outside Moscow, ESA's in Oberpfaffenhofen, Germany, and Tsukuba, Japan.

They even have ham radio!

ISS: Roscosmos says via Telegram "a coolant leak occurred from the external (backup) radiator circuit, which was delivered to the station in 2012;" it says Nauka's main coolant loop is operating normally and "the crew and the station are not in any danger"

I'm going to secure from red alert unless circumstances change.
