Impact craters have been called the “poor geologists’ drill,” since they allow scientists to look beneath to the subsurface of a planet without actually digging down. It’s estimated that Mars has over 600,000 craters, so there’s plenty of opportunity to peer into the Red Planet’s strata – especially with the incredible HiRISE (High Resolution Imaging Science Experiment) camera on board the Mars Reconnaissance Orbiter which has been orbiting and studying Mars from above since 2006.
This beautiful image shows the interior of an impact crater in the Hellas Planitia region of Mars – just north of the gigantic Hellas impact basin located in the southern hemisphere of Mars. This nameless crater is about 6 to 7 kilometers wide in total, but this partial image shows about 1 km of width inside the crater wall. Partway down from the crater rim is a prominent bright layer of bedrock.
HiRISE can operate in visible wavelengths – the same as human eyes — but it also uses near-infrared wavelengths to obtain information on the mineral groups present
The HiRISE team said the colors in this image are enhanced in infrared, and the data shows three distinct bedrock colors: yellow, light blue-green, and dark blue. The colors correspond to different types of rock that were deposited from the impact as nearly flat-lying sheets, perhaps a combination of lava flows and sediments.

Blue layer is fascinating. I wonder what it is.
Copper?
Cobalt?
Yup, and copper sulfide is a pretty good color match. Often found with gold I hear.
It’s an infrared image, so we’re not seeing the actual color of the rock.

Thanks BenLurkin. Impact crater!

the rest of the "Hemisphere of Craters" keyword:
Iridium?
(Maybe that’s where all the Martian dinosaurs went) :-)
This means instead of carbon-based life, there is probably copper-based life on Mars. I think we can now guess Elon’s interest in Mars. There’s a lot of conductivity in the life forms there.
I guess.
Read the article and you will learn what it is.
Looks like my gums before brushing.
Blue is usually a sign of COPPER. White - Calcium. Yellow - Iron as in Limonite.
I did read it before I even made the comment But it was so unclear to me I began kind of imagining it was a huge vein of turquoise.
The article says it’s bedrock. Bedrock is like ice cream, it comes in many flavors.
ha ha!
