Geologists on Earth would most likely call it glacial striation, but I don't think that happened on Mars. More likely a sudden erosion process in a catastrophic event. Third image shows the location of the closeup photo. Last image from Earth: en.wikipedia.org/wiki/Glacial...

Science : Planet's tail of the unexpected
Boston ONE of our neighbouring planets can still pack a few surprises, it seems. Using satellite data, an international team of researchers has found that Venus sports a giant, ion-packed tail that st...

On Opportunity Rover, adhesion of fine dust was observed, but here on Perseverance now I don't think fine dust can explain it. The larger amount on top of Opportunity's wheels was only possible while the wheel was sunken deep into the soil. 📷 link.springer.com/article/10.1...

The map is also usable already since a few months in the free jmars.asu.edu @jmars-gis.bsky.social app. The only tool outside of the original China Space Agency website which has integrated the map. To add it: "Add Layer" and search for "Tianwen", then add the "Color Stretcher" for more contrast.

That mmgis API is new for me. I'll look to get some useful things from that into my areoHDR app.

The API I already use to get the IDs and frame position, but couldn't see the rover location and camera pointing yet.

With this confirmation of atmospheric electric discharges measured only 2m away from Perseverance Rover, the source of perchlorates on Mars is obvious: electrochemistry in the atmosphere. Is it only a thin layer of on the surface in that dry environment without rain so it can be easily scraped off?

Is Marslife.org an ASU or NASA project that they have access to the pointing location for each photo the day of the image release already? Or where is that data available?
