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.”
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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.
