Close-up of Bathurst Inlet Rock by Mars Curiosity

This image of “Bathurst Inlet” rock taken by NASA‘s Mars rover Curiosity with Mars Hand Lens Imager (MAHLI) camera, about 10.5 inches (27 centimeters) away from the top of a rock.   Image credit: NASA/JPL-Caltech/Malin Space Science Systems

The Bathurst Inlet rock is dark gray and appears to be so fine-grained that MAHLI cannot resolve grains or crystals in it. Resolution is about 105 microns per pixel.

MAHLI took the component images for this merged-focus view, plus closer-up images of Bathurst Inlet, during Curiosity’s 54th Martian day, or sol (Sept. 30, 2012). The instrument’s principal investigator had invited Curiosity’s science team to “MAHLI it up!” in the selection of Sol 54 targets for inspection with MAHLI and with the other instrument at the end of Curiosity’s arm, the Alpha Particle X-Ray Spectrometer.
