Hargraves (crater)

Hargraves is an impact crater on Mars. The crater was named after the American geoscientist Robert B. Hargraves, by the IAU in 2006. Hargraves studied impact craters on earth and lunar samples returned by the Apollo program, and was involved in the study of Mars as part of the Viking program.
Hargraves lies between the two largest fossae (valleys) of the Nili Fossae.
