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)

So...lets ask some questions here as the phenomenon persists...
Why this mountain and not the other ones? We are not looking at a volcanic eruption. But something is creating a reaction at the peak of this mountain. Water Ice? It must be sublimating then, is a glacier up there? Just asking questions! |

Why this mountain and not the other ones?... It must be sublimating then, is a glacier up there? https://www.nytimes.com/2018/10/26/science/...arsia-mons.html "The clouds form when water-laden air is pushed upward along a mountain. Cooler, thinner air cannot hold as much water, causing some of the moisture to condense and freeze, forming clouds." Presumably Arsia gets these clouds more often due to its specific topography and its location relative to the winds driven by global circulation. All of the volcanoes get clouds at times. See "The seasonal behavior of water ice clouds in the Tharsis and Valles Marineris regions of Mars: Mars Orbiter Camera Observations", Benson et al, https://www.sciencedirect.com/science/artic...019103503001751 (paywalled, unfortunately.) -------------------- Disclaimer: This post is based on public information only.
