EponymRichard A. Proctor

Proctor is a large crater in the Noachis quadrangle of Mars. It was named in 1973 after Richard A. Proctor, a British astronomer (1837–1888).[1]

The crater contains a 35 x 65 km dark dune field.[2][3] It was one of the first sand dune fields ever recognized on Mars based on Mariner 9 images.[4] The crater's dunes are being monitored by HiRISE to identify changes over time.[5]
