Title: Rock sample brought to earth from the Apollo 12 lunar landing mission
Description:
Close-up view of Apollo 12 sample 12,052 under observation in the Manned 
Spacecraft Center's Lunar Receiving Laboratory. This sample, collected
during  the second Apollo 12 extravehicular activity (EVA-2) of Astronauts
Charles  Conrad Jr., and Alan L. Bean, is a typical fine-grained
crystalline rock with  a concentration of holes on the left part of the
exposed side. These holes  are called vesicles and have been labeled as gas
bubbles formed during the  crystallization of the rock. Several glass-lined
pits can be seen on the  surface of the rock. An idea of the size of the
rock can be gained by  reference to the gauge on the bottom portion of the
number meter.
