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. Hence those living in the north temperate zone, at the season of the year when the earth is at A, or in the Summer, would have long days and short nights, in proportion as they approached the polar circle while those who live in the south temperate zone, at the same time, and when it would be Winter there, would have long nights and short days in the same proportion.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. In the position A, therefore, an observer at the north pole would see the sun constantly, while another at the south pole would not see it at all. “Now it is the inclination of the Earth’s axis, as above described, which causes the lengths of the days and nights to differ at the same place at different seasons of the year, for on reviewing the positions of the globe at A, it will be observed that the line formed by the enlightened and dark hemispheres, does not coincide with the line of the axis and the pole, but that the line formed by the darkness and the light, extends obliquely across the line of the Earth’s axis, so that the north pole is in the light while the south is in the dark.
