Curiosity in the valley of Gediz Vallis – Behind The Black – Robert Zimmerman

The panorama above was created by Curiosity’s right navigation camera on August 28, 2022, and shows the strangely paved Martian terrain directly in front of the rover now that it is inside the valley of Gediz Vallis, scattered flat rocks interspersed with dust. The yellow lines in the overview map to the right indicates the area covered by this panorama. The red dotted line indicates the rovers likely future route to circle around the small mesa Chenapua.

The paved rocks however may not be separate, but merely covered in their low spots by dust. What makes these light rocks significant is that they appear to be the first close examples of the sulfate-bearing layer that the rover has seen in the higher reaches of Mount Sharp since it landed in Gale Crater more than ten years ago. You can see this bright layer clearly in the distance in a panorama taken by Curiosity in June 2021. The rover has now finally reached it, and is about to delve into another layer in the geological history of Mars, a layer that appears easily weathered and carved by the thin Martian atmosphere….
