Geologic Map of Olympus Mons Caldera, Mars. USGS SIM 3470.<\/figcaption><\/figure>\n

The USGS\u2019s Astrogeology Science Center highlights three geologic maps of Mars<\/a> released in late 2021. The maps are large-scale, focusing on specific Martian features (e.g. Olympus Mons, above).<\/p>\n

Though maps have historically covered large areas, with crewed lunar missions on the horizon and other missions across the solar system in the planning stages, large-scale, small-area maps are starting to steal the limelight. These large-scale, small-area maps provide highly detailed views of the surface and allow scientists to investigate complex geologic relationships both on and beneath<\/em> the surface. These types of maps are useful for both planning for and then conducting landed missions.<\/p><\/blockquote>\n

The maps are of Olympus Mons Caldera<\/a>, Athabasca Valles<\/a> and Aeolis Dorsa<\/a>. Interactive versions, with toggleable layers over spacecraft imagery, are also available: Olympus Mons Caldera<\/a>, Athabasca Valles<\/a>, Aeolis Dorsa<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
