One from the archives, circa 1972 — NASA astronaut Ronald E. Evans performing extravehicular activity during the Apollo 17 spacecraft's trans-Earth coast. During his EVA, command module pilot Evans retrieved film cassettes from the Lunar Sounder, Mapping Camera, and Panoramic Camera. The cylindrical object at Evans' left side is the Mapping Camera cassette. 📷 Credit: NASA #nasa #apollo17 #apollo #nasahistory #moonmission #spacewalk #tbthursday
