Lunar Reconnaissance Orbiter photographs SLIM on the Moon
Click for blink animation.
Scientists using Lunar Reconnaissance Orbiter (LRO) were able on January 24, 2024 to obtain a photograph of the SLIM landing site on the Moon, and produce a before and after blink animation showing the lander on the ground.
The two pictures to the right, before and after, were taken from that animation. The bright speck in the after image is SLIM, sitting upside down on the surface. The faint streak of light material going from right to left lower in the photo comes from the fresh ejecta material thrown out from the nearby 1,425-foot-wide Shioli Crater to the west.
This picture confirms once again that SLIM achieved its main goal, landing precisely within a tiny landing zone only 300 feet across.
The landing occurred in the morning on the Moon, so the Sun was in the east. Because SLIM got flipped upside down just before touchdown, its one solar panel ended up facing west, where no sunlight could touch it. Based on the shadows in this picture, east is to the left, and west to the right. The solar panel is sitting in the shadow on SLIM’s right side.
In about a week the Sun will begin setting to the west, illuminating that panel. Engineers in Japan hope that at that time the panel will begin to recharge the spacecraft’s batteries, and it will then begin to operate again, if only a short while before the Sun sets and the very cold and hostile lunar night begins. There is little expectation of SLIM surviving that long two-week lunar night, even if it gets its batteries fully charged.
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

I see Paris
I see France
I see SLIM’s underpants!
That said I’m glad they had the success of a soft landing even though the craft is now upside down All in all a pretty good job considering the success rate of others.
Has anyone speculated on what went wrong? Landed on a rock and rolled over? Solar panel deployment tipped it over? Malfunctioning thruster flipped it over? Narrow positioning of landing legs or failure of one of the legs?
To come so far, so close, just to fail by falling over and can’t get up.
Max: In my previous reports on SLIM, on this very webpage, I quote as well as link to the JAXA press report that describes what happened quite well.
Given that the lander will be lost soon anyway, why don’t they try to flip it over with the maneuvering thrusters? Not powerful enough?
