English: These are three views of
Mare Crisium on the moon, taken by the mapping camera of the
Apollo 17 mission in 1972, facing north-northeast from an altitude of an average of 118 km on Revolution 27 of the mission. At the right is the east margin of Mare Crisium, with the north tip of
Promontorium Agarum visible in the foreground, and
Mare Anguis near the central horizon. The crater
Eimmart is visible in both the right and central photos as a bright patch. The center photo shows an obvious lack of large craters in the mare indicating a relatively young age of the basalt, and the crater Eimmart C is visible as a ring at the edge of the mare near the top center. The left photo shows the western margin of the mare, with the crater
Peirce (larger) and
Swift (smaller) in the mare, and the large crater
Cleomedes near the central horizon. The rays of the crater
Proclus (further to the west, not shown) are prominent in the mare. These photos were taken within minutes of each other. The sun elevation drops from 60 degrees at right to 46 degrees at left as the Command module
America orbited the moon.
