Sols 3444-3445: The curious case of cross-cutting ridges

Tosol’s plan is focusing on examination of the linear ridges that cross-cut the local terrain. These raised ridges look like boxes with their lids cut off and mostly buried in the local bedrock, and all we can see are the vertical box faces sticking up out of the ground.

How these structures actually form is an active area of investigation, and we hope the data we gather tosol will help us “think outside the box” and shed some light on their origin.

The plan includes APXS and MAHLI of the target ‘Dun,’ ChemCam LIBS of ‘Ceres’ (a target on Mars, not the dwarf planet!), and ChemCam RMI mosaic of the Gediz Vallis ridge. Mastcam will be taking stereo images of targets ‘Feorachas’ and ‘Clavel’ as well as a mosaic of some old rover sand tracks to investigate surface granular processes.

Mastcam and Navcam are making several dust devil observations among others, and of course DAN, REMS, and RAD are making their standard observations.

Sols 3442-3443: Deoch-an-Doris

Pasadena CA (JPL) Apr 12, 2022

In Scots Gaelic, “deoch-an-doris” loosely means “one for the road.” Today we planned one more set of investigations on the fascinating Feorachas outcrop before we leave it behind forever.

We first visited it over a month ago as we were climbing up the Greenheugh Pediment and now we have given it a more thorough investigation on the way down thanks to some crafty driving by Curiosity’s rover planners in this craggy terrain.

You can see our old rover tracks extending off into the distance in t … read more
