This crater is 100 feet (30 meters) in diameter and is one of many impressive craters found on Mars. The thin martian atmosphere doesn't burn up meteors the same way Earth's does.
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.
