SLIM survives its third lunar night
Though it was primarily designed to prove its landing system and was never expected to resume operations after enduring the long 14-day-long lunar night, Japan’s SLIM lunar lander has successfully survived its third lunar night, resuming contact with Earth yesterday.
JAXA said on the social media platform X that SLIM’s key functions are still working despite repeated harsh cycles of temperature changes. The agency said it plans to closely monitor the lander’s deterioration.
While the newly downloaded data and photos have some scientific value, the important data is the spacecraft’s engineering status. Finding out what continues to work and what fails after each lunar night will inform engineers on what to do best to build future lunar landers and rovers.
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

Happy accident?
By standing on its head, nozzles up–provides shade?
The nozzles flex so breadboards won’t?
Jeff Wright asked: “By standing on its head, nozzles up–provides shade?”
The nighttime problem is not shade but 2 weeks of cooling. The boards may contract at a different rate than the components and solder joints may crack or separate. Other factors from differential expansion can also cause problems. My guess is that although it was not intended to be designed to survive cold temperatures, the engineers tried to put survival into the design anyway.
