Description
AS17-145-22157 (12 December 1972) --- Scientist-astronaut Harrison Schmitt, Apollo 17 lunar module pilot, uses an adjustable sampling scoop to retrieve lunar samples during the second Apollo 17 extravehicular activity (EVA-2), at Station 5 at the Taurus-Littrow landing site. A gnomon is atop the large rock in the foreground. The gnomon is a stadia rod mounted on a tripod, and serves as an indicator of the gravitational vector and provides accurate vertical reference and calibrated length for determining size and position of objects in near-field photographs. The color scale of blue, orange and green is used to accurately determine color for photography. The rod of it is 18 inches long. The scoop Dr. Schmitt is using is 11 3/4 inches long and is attached to a tool extension which adds a potential 30 inches of length to the scoop. The pan portion, obscured in this view, has a flat bottom, flanged on both sides with a partial cover on the top. It is used to retrieve sand, dust and lunar samples too small for the tongs, another geological tool used by the astronauts. The pan and the adjusting mechanism are made of stainless steel and the handle is made of aluminum. Within the foreground of this scene, three lunar samples were taken--numbers 75060, 75075 and 75080. Astronaut Eugene A. Cernan, crew commander, was using a 60mm lens on the 70mm Hasselblad camera and type SO-368 film to take this photograph.
