The sign accompanying the moon rock. It reads
Apollo 12 Moon Rock
Apollo 12, America's second
lunar mission, left earth on November 14, 1969 and landed on the surface of the
Moon in the early morning hours of November 19, 1969. Astronauts Charles
Conrad and Alan Bean exited the landing module, Intrepid,
twice, mainly to collect rock and soil samples. They were also the first
astronauts to spend a full day on the Moon.
The original rock from which this 449 gram (15.9 oz) sample was taken weighed
2109 grams (4.7 lbs) and was collected at the Apollo 12 landing site, Ocean of
Storms. Using radioactive techniques, scientists have determined the age of
the rock to be about 3.3 billion years.
