Is that a Plume on Arsia Mons?
https://scilogs.spektrum.de/go-for-launch/i...-on-arsia-mons/ Images of the Tharsis region show the emergence of a new prolonged feature that appears to cast a long shadow. It is not visible in this attached image from 06 August 2018. Then we can see something newish near Arsia Mons (the vertical streak) in this image from 19 Sep 2018. And then most striking is this image from 23 Sep 2018, where it appears that a significant shadow is cast (in the direction of the streak in the last image, admittedly). I'm not familiar enough with Martian meteorology to know if this is just a normal occurrence, but it does look weird, at least to me. Hopefully someone will have ideas. If the answer to this is obvious then feel free to lock and/or delete the thread. -------------------- -- Hungry4info (Sirius_Alpha)

Any substantial venting would produce changes in atmospheric chemistry which would be detectable by SAM on Curiosity (which routinely does atmospheric analysis) and by MAVEN, and now certainly by TGO. Since there is a history of seeing these clouds, that would show up in the data. If it's not been found, it's not there.

In two months, we'll have a seismometer on the surface. The comments here are persuasive that we already know what's going on with Arsia Mons, but it'll be nice to have that added source of information and see if any trembling is happening at any of Mars' gigantic volcanoes.

I believe this is the first of its kind...I think Mars 3 had one on it but crashed. Will be nice to put the issue to rest about those big volcano's and when they were last active. And more importantly tectonics (or lack of) I had read a paper in the 90's already that those volcano's were responsible for periodic heating of the planet, thickening of atmosphere, water washing out on the surface and melting of caps. Which was why i was so excited when i saw this. The paper had very compelling evidence..with previous evidence of violent eruptions.Those are pretty big volcano's and an eruption across the surface would be game changing for the next 100,000 years |
