- Longer video of Zhuque-2 launch failure
You need to scroll down to see the second part, which appears to end before the failure.
- Ham radio cubesat released from Tiangong-3
More details about the satellite here.
- PR film from rocket startup Stoke Space
The most interesting part is where the film describes the company’s 2nd stage, which uses many mini-thrusters in a ring to make it reusable. For more info, see this October 2021 post.
- Roscosmos head Borisov claims Soyuz leak hole is about 0.8mm in size
This was part of his press statement that TASS reported earlier, but without including this one detail. How Borisov knows the hole size however is not explained.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

They might have just calculated the hole size from the starting system pressure, the amount of coolant, and the time it took to get to zero pressure.
Probably more factors than that but that’s the basics… I think…
I was wondering if the system that was installed on the Canada-Arm was used to scan for the hole, just like how it scanned the tiles of the shuttle in the past.
Stoke Space trying to bring back plug-nozzles has Bono and Gatland smiling somewhere…
0.8 mm rivet size?
How Borisov knows the hole size however is not explained.
Apparently, the Canadarm camera got a really close look at the hole over the weekend. (Which means, of course, that not just Roscosmos has that imagery, but so do the other major ISS partners as well.)
It doesn’t tell us how the hole got made, though I suppose it has to be said that for the first time with a Russian hardware failure, an extrinisc cause (i.s., MMOD) cannot be excluded!
The Russians have a long history of coolant leaks in their space modules. They are the “used cars” of the space-faring world!
