Title: Astronaut Harrison Schmitt uses scoop to retrieve lunar samples during EVA
Description:
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. The pan
and the adjusting mechanism are made  of stainless steel and the handle is
made of aluminum.
