Landing Sites Landing Sites

Gusev Crater and Meridiani Planum, two regions that show strong evidence of past water activity on Mars, were selected by NASA as the landing sites for the Mars Exploration Rovers based on the recommendations of a large team of scientists and engineers who examined more than 100 locations for landing safety and scientific interest. Spirit landed at Gusev Crater on Jan. 3, 2004 (EST). Opportunity landed at Meridiani Planum on Jan. 25, 2004 (EST). Click on the map below to learn more about the Gusev and Meridiani landing sites. Yellow ellipses are designated for MER-A. Red ellipses are for MER-B. The gray regions represent data returned from the Mars Global Surveyor and Mars Odyssey orbiters.
