The delta deposits in Channel Islands appear to have a relatively shallow slope. If they do plan to go that way maybe they're thinking that the exposure would be good and easy to access.

Using the images from MERovingian's link and increasing the contrast, it is clear that the feature is at/over the local horizon.


Hm, I think you're right. Initially thought that hill was the local horizon.

The plume crash plume in the MSL photo is on/over the horizon. The apparent dust cloud in the Perseverance image appears closer than the horizon.

That being said, this does look a lot like a crash plume.


Or just dust from the landing itself.

On the JPL feed there is a map that has been in view a few times. If the green dot is the estimated landing site it looks pretty dead center of the landing ellipse.

What would be the best option fo a technical stream without any talking heads? Just straight video from mission control with comms would be ideal.

What are the long term plans for Rosetta's orbit? Will it remain at 30km as it gets closer to the sun?

Those are some nice concretions. I wonder if these are the main source of the hematite signature.

Post #18 Question: Were the pebbles transported to the flagstone area by wind, and simply stick better in the narrow strips, or do they result from a more ancient and/or complex process?


Perhaps the pebbles were caught up in the small dunes we see and were left behind in the cracks as the dunes traveled?

I'm aware that the current explanation for features like this are cracks in the bedrock but some of them sure do look like rivulets.
I suppose wind keeps the loose sediment from completely filling in the cracks.
