Cool image time! The picture above, reduced to post here, was taken by Curiosity’s high resolution camera on June 5, 2022 (sol 3494). It shows a close up of another flaky rock near where the rover is presently sitting (the blue dot on the map to the right), similar to the one that I highlighted on May 28, 2022 but zoomed in closer.

Not only can you seen the layered flakes extending out from the rock’s main body, you can see what appear to be small deposits of material between the flakes, as if at one point the material was being placed here by condensation, either from the atmosphere or liquid.

The curvy rounded edges of the rock’s larger flakes could have been caused by the same process, or by long slow wind erosion over the eons since the flakes were formed.

The photo appears to be part of a larger mosaic that the rover’s science team is having the camera take of the strange geology that now surrounds Curiosity. The science team also appears to be continuing its beeline south towards the rover’s original planned route, indicated by the red dotted line on the map. The green dot marks the approximate location of a seasonal recurring dark streak on the cliffside, suggesting some form of seepage, while the white arrows mark a distinct layer that scientists have identified in many places on the flanks of Mount Sharp.

Cool image time! The panorama above, cropped, reduced, and enhanced to post here, was compiled from 29 photos taken on May 31, 2022 by the right navigation camera on the Mars rover Curiosity. It shows the steepness of the slope that the rover ended up parking on yesterday after it completed its drive. As noted in today’s rover update by Abigail Fraeman, Planetary Geologist at NASA’s Jet Propulsion Laboratory:

Curiosity starts the plan parked at an impressive 17˚ pitch (front up) and 17˚ roll (left up) for a total 24˚ tilt. You can get a bit of a sense of the rover’s non-horizontal position by looking at its orientation with respect to the ground in the above Navcam mosaic. Even though this slope is getting close to the limit of what Curiosity can traverse, we don’t think we’ll have any problems unstowing the arm or driving the rest of the way to the top because of the terrain we’re on – nice smooth bedrock with only a thin sand cover is almost the Martian equivalent of a paved road.

On the far right of the image you can also see Curiosity’s tracks. The rover had first approached this slope about 80 feet to the west, then backed off slightly to parallel the slope as it came east and then turned uphill. In the far far distance can be seen the rim of Gale Crater, about about 30 miles away and obscured by the atmosphere’s winter dust.

The overview map above shows Curiosity’s location with the blue dot. The approximate area covered by the section of the panorama above is indicated by the yellow lines. The red dotted line shows the rover’s original planned route. The white arrows indicate what the scientists have dubbed the “marker horizon,” a distinct layer found in many places on the flanks of Mount Sharp that they are very eager to study up close. The green dot marks the approximate location of a recurring slope lineae, a place where the cliff is seasonally darkened by a streak that appears each spring and then fades.
