Not to be confused with aurora, " airglow" is a dimmer luminescence that occurs when air molecules and atoms in the Earth's upper atmosphere absorb solar radiation and then release their excess energy as light. It often indicates a user profile.Ī long exposure panorama taken on Mashowcases the “airglow” phenomenon around Mount Cook, the highest mountain in New Zealand at 12,316 feet. JPL, which is managed for NASA by Caltech, built and manages operations of the Perseverance rover.Account icon An icon in the shape of a person's head and shoulders. The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet. Subsequent NASA missions, in cooperation with ESA, would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith. When I look at this mosaic through red-blue 3D glasses, I’m transported to the western rim of Belva, and I wonder what future astronauts would be thinking if they were to stand where Perseverance once stood when it took this shot.”Ī key objective for Perseverance’s mission on Mars is astrobiology, including caching samples that may contain signs of ancient microbial life. “But it also provides an opportunity to simply enjoy an awesome view. “An anaglyph can help us visualize the geologic relationships between the crater wall outcrops,” said Stack. To help with those efforts, the mission also created an anaglyph, or 3D version, of the mosaic. Perseverance Takes in View at Belva Crater: This anaglyph of Perseverance’s mosaic of Belva Crater can best be viewed with red-blue 3D glasses. The scientists will search for answers by continuing to compare features found in bedrock near the rover to the larger-scale rock layers visible in the distant crater walls. The science team suspects the large boulders in the foreground are either chunks of bedrock exposed by the meteorite impact or that they may have been transported into the crater by the river system. These “dipping beds” could indicate the presence of a large Martian sandbar, made of sediment, that billions of years ago was deposited by a river channel flowing into the lake that Jezero Crater once held. Perseverance took the images of the basin on April 22 (the 772nd Martian day, or sol, of the mission) while parked just west of Belva Crater’s rim on a light-toned rocky outcrop the mission’s science team calls “Echo Creek.” Created by a meteorite impact eons ago, the approximately 0.6-mile-wide (0.9-kilometer-wide) crater reveals multiple locations of exposed bedrock as well as a region where sedimentary layers angle steeply downward. On Mars, impact craters like Belva can provide a type of natural roadcut. On Earth, geology professors often take their students to visit highway “roadcuts” –places where construction crews have sliced vertically into the rock to make way for roads – that allow them to view rock layers and other geological features not visible at the surface. Impact craters can offer grand views and vertical cuts that provide important clues to the origin of these rocks with a perspective and at a scale that we don’t usually experience.” “That’s why our science team was so keen to image and study Belva. “Mars rover missions usually end up exploring bedrock in small, flat exposures in the immediate workspace of the rover,” said Katie Stack Morgan, deputy project scientist of Perseverance at NASA’s Jet Propulsion Laboratory in Southern California. Stitched into a dramatic mosaic, the results are not only eye-catching, but also provide the rover’s science team some deep insights into the interior of Jezero. The Mastcam-Z instrument aboard NASA’s Perseverance Mars rover recently collected 152 images while looking deep into Belva Crater, a large impact crater within the far larger Jezero Crater. The six-wheeled scientist encountered the crater during its latest science campaign in search of rock samples that could be brought to Earth for deeper investigation.
