                     Jezero Crater: Raised Ridges in 3D
             Image Credit: [3]NASA, [4]JPL-Caltech, [5]Ingenuity

   Explanation: Get out your red-blue glasses and [6]hover over the
   surface of Mars. Taken on July 24, the 3D color view is from the Mars
   Ingenuity Helicopter's 10th [7]flight above the Red Planet. Two images
   from Ingenuity's color camera, both captured at an altitude of 12
   meters (40 feet), but a few meters apart to provide a stereo
   perspective, were used to construct the color anaglyph. Ingenuity's
   stereo images were made at the request of the Mars [8]Perseverance
   rover science team. The team is [9]considering a visit to these raised
   ridges on the floor of Jezero Crater during Perseverance's first
   science campaign.
