Scientist-astronaut Harrison H. Schmitt, Apollo 17 lunar module pilot, collects lunar rake samples at Station 1 during the mission’s first spacewalk at the Taurus-Littrow landing site. This picture was taken by astronaut Eugene A. Cernan, commander. The lunar rake, an Apollo lunar geology hand tool, is used to collect discrete samples of rocks and rock chips ranging in size from one-half inch (1.3 centimeters) to 1 inch (2.5 centimeters).
