ALT Two panoramas taken in the morning and afternoon on Mars are combined to create a color-enhanced landscape image. Both panoramas of the area, known as "Marker Band Valley," were taken by the Curiosity Mars rover's navigation cameras. The detailed photo shows yellow coloring in the sky to mark the afternoon hours and it transitions to a blue color to indicate the morning color. The taupe-colored landscape shows a large, rocky hill to the right and smaller rocky hills in the distance toward the center and out into the horizon. To the left is a rocky outcrop and as we get closer to the foreground the area shows rover tracks along the sandy floor. To the bottom-right corner, the backend of the off-white, dusty rover is shown. Part of the rover's wheel can be seen as well as three of its antennas. The Radiation Assessment Detector, or RAD instrument, appears as a white circle in the lower right portion on the back of the rover.

ALT A view of rover tracks in the sandy Martian surface is shown in a photo taken by the Perseverance rover. The tracks go off into the hazy horizon and the image is tinted a beige color. A small piece of the rover is shown off to the lower right.
