The Perseverance landing site has now been named for Octavia E. Butler and from here there will be a meandering climb to get up on top of the "cliffs" that are in the delta.
I think that sediments there may be different than those on top of these "cliffs" and so this is a good thing.
But I'm surprised that the chosen ellipse straddles this feature basically 50:50, as if to say that before it or after it are both equally okay.
AAPG's Destination Jezero Crater: Landing Site of the Mars 2020 Perseverance Rover suggests the geology may be different on each side of these cliffs.
Question: Why Perseverance's landing ellipse straddled the cliffs in the river delta; why so ambivalent about the two different geologies?
Naively I would have expected it to be about 5 km to the right (East) to ensure the landing was in the lower area to ensure sampling of the lower geology, and to decrease chances of slamming into a cliff sideways if some aspects of the new terrain-sensitive landing implementation didn't go as planned.
If I had to guess, it would be that the ellipse was conservative and the folks at JPL had a pretty good idea just where they wanted to land, and nailed it. But that's just my own speculation for now.
This image shows two possible routes (blue and purple) to the delta.
