Mars has a dense core at its center between 930 and 1,300 miles (1,500 to 2,100 kilometers) in radius. It's made of iron, nickel, and sulfur. Surrounding the core is a rocky mantle between 770 and 1,170 miles (1,240 to 1,880 kilometers) thick, and above that, a crust made of iron, magnesium, aluminum, calcium, and potassium.
The panorama is made up of 60 images taken by the Mars Hand Lens Imager (MAHLI) on the rover's robotic arm on March 26, 2021, the 3070th Martian day, or sol, of the mission. These were combined with 11 images taken by the Mastcam on the mast, or "head," of the rover on March 16, 2021, the 3,060th Martian day of the mission.

4 days ago · The Viking landers are two robotic U.S. spacecraft launched by the National Aeronautics and Space Administration (NASA) for the study of the planet Mars. Viking 1 landed in the region of Chryse Planitia (22° N, 48° W) on July 20, 1976, and Viking 2 landed 6,500 km (4,000 miles) away in Utopia Planitia (48° N, 226° W) several weeks later on September 3.
