A strange lunar crater
Lunar Reconnaissance Orbiter recently celebrated its 1000th day of imaging in orbit around the Moon, snapping images and cataloging the Moon’s geology.
Only a week before the science team posted a spectacular oblique view of Ryder Crater. The image is visible below the fold, along with a close-up of the crater’s strange hump-backed boulder-strewn floor.
As the scientists note,
Ryder crater is rather oddly shaped; is it two craters or one? It is 17 km in the long direction and 13 km in its shortest dimension. The western floor of the crater is about 1500 meters below the western rim, while the eastern rim is 3000 meters above the same floor. The eastern shelf, seen in today’s Featured Image, is 5000 meters above the western rim!
The scientists speculate that the crater’s strange shape is probably because of several factors. For one, the crater formed on a steep slope. For another, it appears the crater was caused by an oblique impact of an object that had split prior to contact.
What I like is the beauty and clarity of the images. LRO is truly allowing us to see the lunar surface as it really is.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

I visited the Moon’s surface this past week to do a little prospecting and took these “close in” aerial photos of scale approx. [_________] = 1 to 100 feet. Please visit the URL: http://target.lroc.asu.edu/q3/
to verify my findings of perhaps abandoned LEM descent stages, left on the surface of the moon (and perhaps a moon buggy). I found two locations actually (on my own, perhaps not documented by anyone else?). Coordinates are…
LOCATION 1: Lat: 9.8608 Lon: -19.8189 very accurate, right on top of it within Copernicus Crater.
LOCATION 2: Lat: 0.1187 Lon: 0.7442 very accurate, right on top of it.
Objects of interest are both about 25 feet diameter, similar shape, and about the diameter of a lunar lander.
The protruding arm may be the lunar ladder?
