Another example of the weird taffy terrain in Mars’ death valley
Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on January 30, 2025 by the high resolution camera on Mars Reconnaissance Orbiter (MRO).
The scientists label it dimply as “layers in Helles Planitia.” Other scientists have given this strange landscape a much more interesting label, “taffy terrain.” It is found only in the Hellas Basin, the basement of Mars, having the lowest elevation found anywhere on the red planet. According to a 2014 paper, the scientists posit that this material must be some sort of “a viscous fluid,” naturally flowing downward into “localized depressions.” Because of its weird nature I have posted many cool images of it in the past (see here, here, here, here, and here).
Is taffy terrain still viscous, or has it become solidified? That question I think remains unanswered, though pictures taken of the same spot over time do not yet appear to show changes.
The red dot on the overview map to the right marks the location, deep within the taffy terrain located at the lowest spot within Hellas Basin.
The location is also below 30 degrees south latitude, at 38.6 degrees south. It is therefore close enough to the poles for the taffy to be made up of near surface ice. This supposition is strengthened because plenty of such near-surface glacial features have been found in the regions to the east.
What makes the taffy terrain more intriguing however is the unknown process that pulled and pushed it, exactly like taffy. Determining its viscous nature does not explain why it is twisted in this manner. Even the many glaciers found the Martian mid-latitudes do not produce such shapes, though the surrounding terrain can often encourage it.
In other words, its formation remains unknown, and truly alien.
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
