Traverse of Astronauts Edgar D. Mitchell and Alan Shepard during extravehicular activity (EVA-2) of the Apollo 14 mission. (a) Edgar D. Mitchell moves across the lunar surface as he is studying a map, trying to figure out where they are in vain; both astronauts thought they were much closer to Cone Crater than they actually were, and they did not recognize any landmarks in their view (picture was taken at location B1). (b) Outline of the traverse from Lunar Module to Cone Crater via B1 and back. Station C1 indicates “Saddle Rock,” where the last sample was retrieved before returning to the Lunar Module. Neither astronaut noticed that “Saddle Rock” was depicted as a landmark on their map. It was only after the completion of the mission that they had realized that were only 30 m from the rim of Cone Crater. Picture Credit: NASA/USGS and Google
