Orion completes burn to send spacecraft back to Earth
NASA’s Orion capsule yesterday successfully fired its engines as it zipped past the Moon to send it on a trajectory back to Earth, with splashdown in the Pacific off the coast of California scheduled for December 11, 2022.
Not all was hunky-dory, however. Prior to the burn a power unit shut down unexpectedly.
A power unit on board the Orion spacecraft turned off four devices “responsible for downstream power” that connect to the Artemis 1 vehicle’s propulsion and heating subsystems, NASA officials wrote in a statement. But mission personnel swiftly put a fix in place and the mission is carrying on, the statement emphasized. “Teams confirmed the system was healthy and successfully repowered the downstream components,” agency officials wrote in the statement, released late on Sunday. “There was no interruption of power to any critical systems, and there were no adverse effects to Orion’s navigation or communication.”
Engineers think the shut down was related to a test performed in connection with an earlier incident.
Regardless, all now appears well for that December 11nd splashdown.
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 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

Is the capsule fully functional in terms of having the infrastructure to maintain an environment suitable for astronauts, and is it doing so?
No, it doesn’t have full ECLSS, as it’s known in NASAspeak. For some extraordinary reason, the first in-flight test of that system will occur during a crewed flight around the Moon.
