The yellow dot shows the landing site of Apollo 17 - the last manned mission to the Moon. Apollo 17 landed on the floor of a deep narrow valley containing dark soil. The valley is bounded on three sides by highlands which form part of the eastern rim of the Serenitatis basin. Using the lunar rover, the crew traveled 19 miles (30km), a distance equivalent to the diameter of the partly buried Littrow crater, found half-way between the center and the upper-right corner of the photo. During the mission the astronauts discovered some orange soil that turned out to consist of colored glass beads which had been produced during volcanic eruptions.
