MRO is equipped with three cameras. 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.
This image of a dust devil on Mars comes from the HiRise camera in 2012. It was big. "The length of this whirlwind's shadow indicates that it was more than half a mile (800 meters) high -- about the size of the United Arab Emirate's Burj Khalifa, the tallest building on Earth," NASA said.
