Russian oxygen regenerator malfunctions again
The Russian oxygen regenerator in the Zvezda module of ISS has malfunctioned again, the second time in a week.
“After the Elektron-VM system was deactivated, the crew, guided by the main operational group, dismantled it in order to detect faults. Oxygen will be generated by a backup system located in the US section until repairs are completed,” the spokesperson said.
This unit was launched with Zvezda in 2000. After ten years of operation it needed repair In 2010, and then operated for another ten years until last week’s failure. Though this second failure after last week’s repair could be fixable, the age of the unit raises reasonable questions about its future.
That it has worked for twenty years, and could still be fixed, speaks well for this Russian design however. Its longevity reminds me of home appliances from the mid-20th century, which routinely were expected to last many decades, and did.
If the time has come to replace it, however, I have doubts about any new “upgraded” unit. Technology development in both Russia and the U.S. has fallen in love with complexity, which often results in less reliability, shorter lifespans, and often units that fail to do what they were designed for. I fear the same would happen with any new unit.
Readers!
My annual February birthday fund-raising drive for Behind the Black is now over. Thank you to everyone who donated or subscribed. While not a record-setter, the donations were more than sufficient and slightly above average.
As I have said many times before, I can’t express what it means to me to get such support, especially as no one is required to pay anything to read my work. Thank you all again!
For those readers who like my work here at Behind the Black and haven't contributed so far, please consider donating or subscribing. 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

Was this the same model that caused the fire on Mir? Seems there will be a hole in the market for someone to offer a low-cost, reliable unit when folks start asking for such things.
David M. Cook: No, the unit that burned on Mir was an earlier design, quite different than Elektron.
Small edit in title: I think it’s “regenerator”
Andi: Thank you. Fixed.
@david Cook: The fire on Mir was from candles they burn that put out oxygen. Goofy right? Feels backwards.

Lithium perchlorate.
I bet Space X is getting a conference call from NASA today.
Hey Bob, still got that old washing machine running?
Spectrum Shift: Yup. Like a dream. Wife is very happy.
