Another drive by Perseverance rover on sol 1137, takes the rover further West to site number 52.0748. This L-NavCam was assembled and roughly processed using all 16 available tiles (edited as the tiles are now in)

A COSMIC ARROW PIERCED PLUTO'S HEART — IS IT STILL THERE BENEATH THE SURFACE?

A giant impact likely formed Pluto’s heart-shaped basin, Sputnik Planitia. A big chunk of the impactor’s core might still be buried under the ice.

Why is Methane Seeping on Mars?

The most surprising revelation from NASA’s Curiosity Mars Rover — that methane is seeping from the surface of Gale Crater — has scientists scratching their heads.

Check out this post by Eleni Ravanis on the case hardening process that might have led to its formation. Associated with near-surface water-rock interactions, its study could have implications for past climate and surface water on Mars.

Sols 4157-4158: What is That??

Curiosity finds odd rocks with "dragon scales" texture.
"We have seen a lot of layered rocks over the last 12 years on Mars, but these ones really stand out by the dizzying pattern they trace on the rock surfaces."

@franco_vazza they do start the Tour in foreign countries every year, for promotional purposes. Recently in Denmark for example. Giro did it as well in Israel a few years ago, they raced in the desert!

wow what a fascinating Martian sight, wish there were a dual stereo pair of images to see this one in 3D!

@PaulHammond51 Oh wow, fantastic, thanks a lot Paul!
How did you know it was there, since it is not displayed on the raw images web page? I see that the two images have the same link except with a NRB instead of NLB. Does it mean that all images are available as pairs in the same way?

Absolutely fascinating Stereo3D view of this Martian landscape.

Many thanks to @PaulHammond51 for finding the right-eye view from the rover's R-Nav Cam.

To get the Stereo3D effect, just let your eyes' line of sight be parallel (not cross-eyed) with left eye in front of left image and right eye in front of right image.
