The icy terrain near one of Starship’s prime candidate landing spots on Mars
Click for original image.
Cool image time! The picture to the right, cropped to post here, was taken on August 22, 2023 by the high resolution camera on Mars Reconnaissance Orbiter (MRO). The camera team labeled the picture a “terrain sample,” which generally means it was not taken as part of any scientist’s specific research request, but to fill a gap in the schedule so as to maintain the camera’s proper temperature. When the team needs to do this, they try to pick a location in the gap that might have some interesting features. Sometimes such pictures show relatively boring features. Sometimes the results are fascinating.
In this case the location chosen was in the northern lowland plains of Mars, in a region called Amazonis Planitia. At 38 degrees north latitude it is not surprising that the photo shows ice features. All the depressions here appear to have an eroding glacier, while the surrounding plateau resembles an untouched snow field in the very early spring, the snow beginning to sublimate away to leave the top rough and stuccoed. Note too that these depressions are likely not impact craters (they have no upraised rims and many are distorted in shape), but were likely formed by that same sublimation process.
On the overview map to the right, the small green dot marks this location, about 25 miles to the southeast of one of Starship’s four prime landing sites, indicated by red and marked #4. This location is also very close to the region that SpaceX had chosen as the prime landing region for its Mars’ version of Dragon, when the company was still considering sending Dragon there.
The picture illustrates again why SpaceX is interested in this location. There is a lot of near surface ice readily available, while the ground itself is flat making for a landing zone with a large margin for error. According to the research work done by scientists for SpaceX about these locations, #4 “has the thickest ice from radar returns and geomorphology.” The biggest problem landing in this region might be that ice, which will likely be melted by the spaceship’s landing burn.
Whether Starship ever gets here remains unknown, mostly because its development remains stymied by the bureaucracy in Washington, DC.
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.
