More glaciers on Mars

Cool image time! The picture to the right, rotated, cropped, reduced, and sharpened to post here, was taken on September 26, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The scientists label this image “Moraine-like assemblage exposed by ice retreat.” I say: If anyone still doubts the extensive presence of near-surface ice on Mars, this picture should put that doubt to rest.
The white dot on the overview map above marks the location, deep within the 2,000-mile-long strip in the Martian northern mid-latitudes that I label “glacier country,” because practically every picture taken there shows glacial features. This picture is just one more example. As the inset in the overview above shows, this flow is coming down from the exterior rim of an unnamed, partly obscured ancient 17-mile-wide crater, dropping about 7,000 feet from the rim’s peak. This particular section shows the last 3,000 feet of that descent, as the glacier worked its way through a gap in a ridge paralleling that rim.
The image label refers to the flow features that appear to be corroding away. It appears the full data set suggests that corrosion is exposing the material pushed downward by that glacier, what on Earth we call a moraine.
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 or from any other book seller. If you want an autographed copy the price is $60 for the hardback and $45 for the paperback, plus $8 shipping for each. Go here for purchasing details. 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
