Astronaut Harrison H. Schmitt, Apollo 17 lunar module pilot, stands near the deployed United States flag on the lunar surface during extravehicular activity (EVA) of NASA's final lunar landing mission in the Apollo series. The Lunar Module (LM) is at left background and the Lunar Roving Vehicle (LRV) at right background (partially obscured). The photo was made by astronaut Eugene A. Cernan, commander. While astronauts Cernan and Schmitt descended in the LM "Challenger" to explore the Taurus-Littrow region of the moon, astronaut Ronald E. Evans, command module pilot, remained with the Command and Service Modules (CSM) "America" in lunar orbit.
