![]() ![]() ![]() Grains that are determined to be polymineralic, or those that are made up of multiple minerals, can provide important information about the geology and composition of their source terrains. ![]() Compositional information of the grains from these instruments can show if the grains are polymineralic or monomineralic. Larger grains are good targets for exploring elemental and mineral composition with PIXL and SHERLOC because these instruments can collect multiple analysis points on each large grain. Slightly obscured by shadow from the rover in this image, this abrasion patch is exciting because of the large grains seen in and around the abrasion patch. Most recently, Perseverance performed an abrasion named Ouzel Falls, pictured above. Each unique rock, boulder, or sediment that the Science team examines could be a new piece of the puzzle for understanding source terrain, transport, and erosional processes occurring within and beyond Jezero. Sitting at the edge of Belva crater on top of the fan, Perseverance has been investigating sediments that were transported to their location via the ancient streams that flowed into Jezero. ![]() The Perseverance rover has been exploring the top of the Western fan in Jezero crater for some time now, but new observations never fail to offer new insights. ![]()
