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.

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.
“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

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.
