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.
As Mars orbits the Sun, it completes one rotation every 24.6 hours, which is very similar to one day on Earth (23.9 hours). Martian days are called sols – short for "solar day." A year on Mars lasts 669.6 sols, which is the same as 687 Earth days. Mars' axis of rotation is tilted 25 degrees with respect to the plane of its orbit around the Sun.
4 days ago · Mars, fourth planet in the solar system in order of distance from the Sun and seventh in size and mass. It is a periodically conspicuous reddish object in the night sky. Mars is designated by the symbol ♂. Sometimes called the Red Planet, Mars has long been associated with warfare and slaughter. It is named for the Roman god of war.
