Credit: NASA\/JPL-Caltech<\/figcaption><\/figure>\n<p>\u201cIf there were astronauts in orbit over Mars, this is the perspective they would have,\u201d said Jonathon Hill of Arizona State University, operations lead for Odyssey\u2019s camera, called the Thermal Emission Imaging System, or THEMIS. \u201cNo Mars spacecraft has ever had this kind of view before.\u201d<\/p>\n<h2 id=\"section-1\" class=\"wp-block-heading\"><strong>How It Was Done<\/strong><\/h2>\n<p>The reason why the view is so uncommon is because of the challenges involved in creating it. Engineers at NASA\u2019s Jet Propulsion Laboratory in Southern California, which manages the mission, and Lockheed Martin Space, which built Odyssey and co-leads day-to-day operations, spent three months planning the THEMIS observations. The infrared camera\u2019s sensitivity to warmth enables it to map ice, rock, sand, and dust, along with temperature changes, on the planet\u2019s surface.<\/p>\n<p>It can also measure how much water ice or dust is in the atmosphere, but only in a narrow column directly below the spacecraft. That\u2019s because THEMIS is fixed in place on the orbiter; it usually points straight down.<\/p>\n<p>The mission wanted a more expansive view of the atmosphere. Seeing where those layers of water-ice clouds and dust are in relation to each other \u2013 whether there\u2019s one layer or several stacked on top of each other \u2013 helps scientists improve models of Mars\u2019 atmosphere.<\/p>\n<p>\u201cI think of it as viewing a cross-section, a slice through the atmosphere,\u201d said Jeffrey Plaut, Odyssey\u2019s project scientist at JPL. \u201cThere\u2019s a lot of detail you can\u2019t see from above, which is how THEMIS normally makes these measurements.<\/p>\n<p>Because THEMIS can\u2019t pivot, adjusting the angle of the camera requires adjusting the position of the whole spacecraft. In this case, the team needed to rotate the orbiter almost 90 degrees while making sure the Sun would still shine on the spacecraft\u2019s solar panels but not on sensitive equipment that could overheat. The easiest orientation turned out to be one where the orbiter\u2019s antenna pointed away from Earth. That meant the team was out of communication with Odyssey for several hours until the operation was complete.<\/p>\n<p>The Odyssey mission hopes to take similar images in the future, capturing the Martian atmosphere across multiple seasons.<\/p>\n<h2 id=\"section-2\" class=\"wp-block-heading\"><strong>Over the Moon<\/strong><\/h2>\n<p>To make the most of their effort, the mission also captured imagery of Mars\u2019 little moon Phobos. This marks the seventh time in 22 years that the orbiter has pointed THEMIS at the moon in order to measure temperature variations across its surface.<\/p>\n<p>\u201cWe got a different angle and lighting conditions of Phobos than we\u2019re used to,\u201d Hill said. \u201cThat makes it a unique part of our Phobos dataset.\u201d<\/p>\n<p>The new imagery provides insight into the composition and physical properties of the moon. Further study could help settle a debate over whether Phobos, which measures about 16 miles (25 kilometers) across, is a captured asteroid or an ancient chunk of Mars that was blasted off the surface by an impact.<\/p>\n<p>NASA is participating with JAXA (Japan Aerospace Exploration Agency) in a sample return mission to Phobos and its sister moon, Deimos, called Mars Moon eXplorer, or MMX. Odyssey\u2019s Phobos imagery will be helpful to scientists working on both Odyssey as well as MMX.<\/p>\n<h2 id=\"section-3\" class=\"wp-block-heading\"><strong>More About the Mission<\/strong><\/h2>\n<p>THEMIS was built and is operated by Arizona State University in Tempe.\u00a0 JPL is a division of Caltech in Pasadena.<\/p>\n<p>For more information about Odyssey:<\/p>\n<\/p>\n<p><strong>News Media Contacts<\/strong><\/p>\n<p>Andrew Good<br \/>Jet Propulsion Laboratory, Pasadena, Calif.<br \/>818-393-2433<br \/>andrew.c.good@jpl.nasa.gov<\/p>\n<p>Karen Fox \/ Alana Johnson<br \/>NASA Headquarters, Washington<br \/>301-286-6284 \/ 202-358-1501<br \/>karen.c.fox@nasa.gov \/ alana.r.johnson@nasa.gov<\/p>\n<p>2023-174<\/p>\n<\/div>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><br \/>\n<br \/><br \/>\n<br \/><a href=\"https:\/\/www.nasa.gov\/missions\/odyssey\/nasa-orbiter-snaps-stunning-views-of-mars-horizon\/?rand=772197\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The Odyssey orbiter captured clouds and dust in the Red Planet\u2019s skies, along with one of its two tiny moons.
