Russian astronauts complete spacewalk to prepare ISS for Nauka
Two Russian astronauts yesterday successfully completed an almost seven-hour spacewalk removing and repositioning equipment to prepare ISS for the arrival of Nauka next year, Russia’s next module for ISS.
The Pirs module will be removed and junked next year to make room for the research lab Nauka — Russian for “science.” Several Russian-directed spacewalks will be required to deal with all this. The plan calls for attaching a cargo ship to Pirs in order to guide it to a fiery reentry.
The new 22-ton lab — stretching 43 feet (13 meters) long — is so big that it will be launched from Kazakhstan by a powerful Proton rocket. Once at the orbiting outpost, it will double as an air lock and docking port.
Earlier it had been announced that they would also do an inspection of the area on Zvezda where they had also discovered a small crack, the cause of the longstanding leak on the station. It appears they did not do this. probably because astronauts inside the station had placed a new permanent patch on the leak, and the work they were doing during the spacewalk carried a higher priority.
Expect that inspection to eventually occur, but for now the cause of that crack remains unknown.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either. IMPORTANT! If you donate enough to get a book, please email me separately to tell me which book you want and the address to mail it to.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

What is the reason for junking the Pirs module? End of service life?
I hope it’s not something stupid like “ran out of connection ports, gotta make room.”
V-Man: The latter is the answer. I also think that Pirs was a stopgap solution to provide an airlock because of the delays getting Nauka launched.
