This map of Mars shows all of the landing sites proposed for the Mars Science Laboratory (red dots) and the four final candidate sites (blue dots). From the four final sites of Eberswalde crater, Gale crater, Holden crater, and Mawrth Vallis, Gale eventually was selected as the landing site. The white shaded areas are more than 30 degrees north and south of the equator and off limits to MSL because of seasonally harsh (cold) conditions expected there. The black areas are above 0 kilometer in elevation and too high to be considered for landing. More information about each of the proposed sites can be found on NASA's Marsoweb website.
