The area formed more than 4 billion years ago (the darkest brown on the map) is three times as large.\u00a0The new map also backs up the idea that Mars was geologically active until recently, and that liquid water once was present on the surface.<\/em><\/p>\n<p style=\"text-align: center;\"><a href=\"http:\/\/pubs.usgs.gov\/sim\/3292\/\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" data-attachment-id=\"8316\" data-permalink=\"https:\/\/hobbyspace.com\/Blog\/?attachment_id=8316\" data-orig-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2014\/07\/Map_500x371.jpg\" data-orig-size=\"500,371\" data-comments-opened=\"1\" data-image-meta=\"{&quot;aperture&quot;:&quot;0&quot;,&quot;credit&quot;:&quot;&quot;,&quot;camera&quot;:&quot;&quot;,&quot;caption&quot;:&quot;&quot;,&quot;created_timestamp&quot;:&quot;0&quot;,&quot;copyright&quot;:&quot;&quot;,&quot;focal_length&quot;:&quot;0&quot;,&quot;iso&quot;:&quot;0&quot;,&quot;shutter_speed&quot;:&quot;0&quot;,&quot;title&quot;:&quot;&quot;}\" data-image-title=\"Map_500x371\" data-image-description=\"\" data-image-caption=\"\" data-large-file=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2014\/07\/Map_500x371.jpg\" class=\"aligncenter size-full wp-image-8316\" src=\"http:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2014\/07\/Map_500x371.jpg\" alt=\"Map_500x371\" width=\"500\" height=\"371\" srcset=\"https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2014\/07\/Map_500x371.jpg 500w, https:\/\/hobbyspace.com\/Blog\/wp-content\/uploads\/2014\/07\/Map_500x371-300x222.jpg 300w\" sizes=\"auto, (max-width: 500px) 100vw, 500px\" \/><\/a><\/p>\n<p>Abstract:<\/p>\n<p style=\"padding-left: 30px;\"><em><span style=\"color: #000000;\">This global geologic map of Mars, which records the distribution of geologic units and landforms on the planet&#8217;s surface through time, is based on unprecedented variety, quality, and quantity of remotely sensed data acquired since the Viking Orbiters. <\/span><\/em><\/p>\n<p style=\"padding-left: 30px;\"><em><span style=\"color: #000000;\">These data have provided morphologic, topographic, spectral, thermophysical, radar sounding, and other observations for integration, analysis, and interpretation in support of geologic mapping. <\/span><\/em><\/p>\n<p style=\"padding-left: 30px;\"><em><span style=\"color: #000000;\">In particular, the precise topographic mapping now available has enabled consistent morphologic portrayal of the surface for global mapping (whereas previously used visual-range image bases were less effective, because they combined morphologic and albedo information and, locally, atmospheric haze). <\/span><\/em><\/p>\n<p style=\"padding-left: 30px;\"><em><span style=\"color: #000000;\">Also, thermal infrared image bases used for this map tended to be less affected by atmospheric haze and thus are reliable for analysis of surface morphology and texture at even higher resolution than the topographic products.<\/span><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Check out this cool new improved map of the geologic features of Mars; A Beautifully Detailed New Geologic Map of Mars &#8211;\u00a0Science\/WIRED USGS Scientific Investigations Map 3292: Geologic Map of Mars USGS Map 3292 (pdf)\u00a0 USGS Geologic Map of Mars &#8211; pamphlet (pdf) The onslaught of up-close exploration in recent years has yielded a ton &hellip; <a href=\"https:\/\/hobbyspace.com\/Blog\/?p=8315\" class=\"more-link\">Continue reading <span class=\"screen-reader-text\">New geologic map of Mars<\/span> <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"jetpack_post_was_ever_published":false,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[27,78,36],"tags":[],"class_list":["post-8315","post","type-post","status-publish","format-standard","hentry","category-eyes-in-the-sky","category-mars","category-multiple-media"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/p34aWK-2a7","jetpack-related-posts":[{"id":21866,"url":"https:\/\/hobbyspace.com\/Blog\/?p=21866","url_meta":{"origin":8315,"position":0},"title":"Space sciences roundup &#8211; May.21.2020","author":"TopSpacer","date":"May 21, 2020","format":false,"excerpt":"A sampling of recent articles, videos, and images from space-related science news items (find previous roundups here): Mars ** The Mars 2020 Perseverance Rover is getting ready for its launch in a few weeks.
