Eponym Emma Dean

Emma Dean is a small impact crater in the Meridiani Planum extraterrestrial plain situated within the Margaritifer Sinus quadrangle (MC-19) region of the planet Mars. This geological feature was visited by the Opportunity rover from sols 929 to 943. The much larger crater Victoria lies about 100m to the east. Emma Dean lies directly on top of the ejecta blanket from Victoria and could therefore expose material originating from deep inside Victoria. The crater is named after the Emma Dean, one of the boats in John Wesley Powell's Grand Canyon expedition. [1]
