Glaciers in the Phlegra Mountains on Mars
Click for full image.
Cool image time! The photo to the right, cropped to post here, is just one of the many hundreds taken by the high resolution camera on Mars Reconnaissance Orbiter (MRO) as well as Europe’s Mars Express orbiter showing the thick icy glacial flows that surround practically every mountain or hill in the Phlegra mountains of Mars.
This picture was taken on November 3, 2021, and shows the eroding foot of an eroding glacial flow coming down from a small hill in a southeastern part of these mountains dubbed Phlegra Dorsa. The downward grade is to the north.
At 30 degrees north latitude it is not surprising these glacial flows are eroding, as they are at the southernmost limit of the mid-latitudes bands where such glaciers are found. Closer to the equator scientists have yet to find much evidence of ice.
The repeating arcs at the foot of this glacier suggest that it pushed downward in cycles, with each later cycle traveling a shorter distance. This supposition makes sense, considering scientists think the ebb and flow of these Martian glaciers has been determined by the cyclical changes in the planet’s rotational tilt.
The overview map below not only gives the context, it shows this location relative to the candidate landing sites for SpaceX’s Starship spacecraft.
The yellow dot indicates the location of these eroded glaciers. The black dots were high-res images taken initially by MRO when SpaceX’s was planning to land a Dragon capsule on Mars. The numbered white dots were later images taken for Starship. The red dots indicate Starship’s four prime candidate landing zones presently being considered.
Today’s image is about 150 miles away from the nearest Starship landing site, #9 to the northwest.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Only now does it appear that Washington might finally recognize this reality.
In 2020 when the world panicked over COVID I wrote that the 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. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
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.

Wayne,
Do YouTubers (specifically you) Dream of Electric Subscribers?
I suppose I should express gratitude. It looks like I’ll have an extra nine hours to listen to PKD since
Winter Storm Kenan is on its way with Heavy Snow, Strong Winds and hopefully Blizzard Conditions.

Original Mark–
I’m on the Lake Michigan coast, we just had 2 back-to-back snowstorms (the infamous “lake effect snow.”) Very cold (5-ish) but nothing like Minnesota.
Har– I don’t even have an account for YT. Unfortunately (or not) the monetization-window has come and gone with them.
The Soviet Mars 3 probe made the first successful soft landing on Mars ( May 28, 1971 at 15:26:30 UTC), although it stopped transmitting data 110 seconds later. Here is video with interesting original film sequences and animations.
“The Secret Landings on Mars”
” …. The (Mars 2) mission was shortly followed by Mars 3, which completed its goal of becoming the first spacecraft to land on the red planet and capture footage of its rocky surface. Minutes after its activation, the rover began transmitting data back to Earth. But 14 seconds after it started moving, the first man-made object to reach Mars lost signal. Before going black, the rover transmitted a fuzzy black and white image. It then went silent forever. ….
