This image is digitally generated from topographical maps collected by satellite. There are no probes on Mars that are located in a place where they could actually take a picture like this. EDIT: My first sentence was wrong. As finnh points out, it's actually based on a real satellite photo that was then stretched to give the illusion of a perspective from low altitude.

It is in fact a synthetic image constructed from a couple data sources. Not a real image taken from a camera. It may as well be one of those "artists conception of...." images used whenever a new planet is discovered.
- finnh 8y agoI think that's just for the perspective, though? We'd have to be flying much, much lower to get the perspective shown in the image. The straight-overhead view is less CGI-y (still composed, but of multiple overhead strips): https://www.esa.int/spaceinimages/Images/2018/12/Plan_view_of_Korolev_crater https://www.esa.int/spaceinimages/Images/2018/12/Plan_view_o... I'd like to know more about the input images...
