Martian taffy terrain
Click for original image.
Cool image time! The picture to the right, rotated, cropped, reduced, and enhanced to post here, was taken on April 11, 2024 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). It shows a typical area of what scientists have labeled “taffy terrain,” a landscape made up of strangely twisted bands that look like someone was pulling the ground repeatedly, just like taffy.
Based on the lower crater count found here, taffy terrain is thought to be relative young, formed around three billion years ago. While the exact formation process is not yet understood, scientists theorize that it was caused by some type of “viscous fluid” that settled into localized depressions.
The location is 40 degrees south latitude, so it is entirely possible we are seeing some form of glacial material, ice in these low spots that has no place to go but is warped over time by the same kind of tidal and rotational planetary effects that cause waves and tides in the oceans on Earth.
The white dot on the overview map to the right marks the location, on the eastern edge of the taffy terrain region inside Hellas Basin, what I like to call the basement of Mars.
This picture was likely taken to study the edge of the terrain, to try to determine a source for the taffy and thus determine its make-up. As far as I can see, however, there is no obvious place in this image or the full picture where this material is venting. Instead, it appears to be a sea of taffy being pulled and twisted by slow currents as it flows into the low spots.
Another geological mystery totally unique to Mars that will likely remain so until humans are walking the surface with rock hammers. If this is ice however it makes the floor of Hellas a very valuable piece of real estate, as it not only would have easily accessible water, but the lower elevation would give it a thicker atmosphere that provides a number of advantages.
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
