Russian spacewalk ends earlier due to spacesuit power problem
A Russian spacewalk yesterday to continue the configuration of Europe’s robot arm for the Russian half of ISS was cut short after four hours when the power system in Oleg Artemyev’s spacesuit begin producing unexpected “voltage fluctuations.”
“I have a message, voltage low,” Artemyev radioed Russian ground controllers around 12 p.m. EDT (1600 GMT). An engineer at Russia’s mission control center near Moscow warned Artemyev he would lose communications if his suit ran out of power.
Russian flight director Vladimir Solovyov then jumped on the line to tell Artemyev to head back to the safety of the airlock. “Oleg, this is Solovyov,” he said. “Drop everything and start going back (to the airlock) right away. Oleg, go back and connect to station power.”
This problem occurred about two hours into the spacewalk. The second astronaut, Denis Matveev, continued working at the robot arm for another two hours before mission control ordered him to end the walk early.
According to Russian officials, Artemyev was never in any danger, though the urgency in which he was ordered to come inside suggests otherwise. According to another news report, a power loss could have also shut down the spacesuit’s “pumps and the fan.”
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

So they left a guy alone outside, for two hours, working without a backup? What happens if he gets in trouble? Bonk his head or something?
V-Man: that’s a very good point. But, I have noticed that Western safety standards are not global. I’ve seen practices that make me cringe, but not my place to say, at the moment.
“Artemyev was never in any danger, though the urgency in which he was ordered to come inside suggests otherwise.”
I would think that if your spacesuit is failing, in space, you are in danger.
