The moon rock was collected in 1972 by Astonaut Jack Schmitt during the last visit of humans to the moon on the Apollo 17 mision. The fragment weighs 19.35 grams. The entire rock was 8110 grams when it was brought to Earth. This is mare basalt and it is about 3.37 billion years old, which is older than most of the rocks on the surface of the Earth.
There were more than 2500 visitors who visited the exhibition in two days (13th and 14th April 2009). So now these 2500 people can proudly say I have "Touched a Moonrock".
