A dust devil, an avalanche, a moon and a crater all made the cut of top Mars Reconnaissance Orbiter images.

Some of MRO's images appear in distinctly un-martian colors thanks to the use of false color, an image processing technique that helps certain details stand out.

MRO's Context Camera instrument spotted this crater and NASA originally shared this HiRise image in 2014.

The Mars Color Imager takes fisheye images, the Context Camera snaps the surface in black and white and the High-Resolution Imaging Science Experiment (HiRise) delivers most of the knockout views we've come to expect from the orbiter.

MRO's HiRise camera caught this view of a towering dust devil in 2012.

This image of a dust devil on Mars comes from the HiRise camera in 2012.
