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.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the 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. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.

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.
