The larger crater that sits within this crater, called the Airy Crater, originally defined zero longitude for Mars, but as higher resolution photos became available, a smaller feature was needed. This crater, called Airy-0 (zero) was selected because it did not need to adjust existing maps.
These days, longitude on Mars is measured even more precisely using radio tracking of landers such as InSight, but everything is still defined to keep zero longitude centered on this crater.
This image was captured by the High-Resolution Imaging Science Experiment (HiRISE), on the Mars Reconnaissance Orbiter. The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel.
