    A grayscale image of a cratered lunar surface. An inset on the right shows two arrows pointing at tracks on the moon, emphasizing a specific area.
    Arrows point to the Chang’e-4 landing site on the moon’s Von Kármán crater, which is about 440 meters across. NASA’s Lunar Reconnaissance Orbiter shot this photo looking across the floor of the crater toward the west wall. The mountains are 3,000 meters high.
    A lunar lander sits on the moon's surface with a black sky in the background. The lander has various instruments and antennas, reflecting sunlight.
