EponymRichard A. Proctor, a British astronomer (1837–1888)

Proctor is a large crater in the Noachis quadrangle of Mars, located at 48° south latitude and 330.5° west longitude. It measures 168.2 kilometres (104.5 miles) in diameter and was named after Richard A. Proctor, a British astronomer (1837–1888).[1]

Dune fields[edit]

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]
