IBEX in safe mode
On February 18, 2023, NASA’s Interstellar Boundary Explorer (IBEX) went into what the engineers have dubbed “contingency mode”, which seems to be a variation of safe mode, due to a computer issue that is preventing the spacecraft from accepting commands.
While fight [sic] computer resets have happened before, this time the team lost the ability to command the spacecraft during the subsequent reset recovery. The team also was unsuccessful in regaining command capability by resetting ground systems hardware and software.
Flight software still is running, and the spacecraft systems appear to be functional. However, while uplink signals are reaching the spacecraft, commands are not processing. If the mission team’s efforts to find and remedy the loss of command capability remain unsuccessful, IBEX will perform an autonomous reset and power cycle on March 4.
IBEX was designed to study the boundary between the interstellar space and the solar system, and do it somehow from Earth orbit.
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

“ and do it somehow from Earth orbit.” Good one!
Minor edit at end of first paragraph: “from accepting commands”
Andi: I promised you such things will happen! Fixed. Thank you.
Mr Z.
Not your error. “The fight computer…”.
Checked the link. NASA posted it that way.
sippin_bourbon: Heh. Didn’t notice that. I had simply cut and pasted from the original. I have added “sic” after “fight” to make it clear the source of the typo.
Every time I see the word “ibex”, I can’t help but think of “43-man squamish”, a sports parody that appeared in MAD Magazine some 50+ years ago.
