Moon Rock from the Apollo moon landing

In December 1969, museum visitors queued round the block to see a sample of rock brought back from the Moon by the Apollo 11 lunar landing.

Study of the specimens that astronauts brought back from the Moon allowed scientists, for the first time, to investigate the geological history of another world.

Rocks from the Moon are extremely old compared to those on Earth. They range in age from about 3.2 billion years up to about 4.5 billion years old, whereas the Earth's oldest rocks date from about 3.9 billion years. Older formations have been destroyed and recycled by the constant shifting of the Earth's tectonic plates.

Today, a piece of Moon rock from the Apollo 12 mission, on loan from NASA, is on display as part of the exhibition The Evolution of Wales at National Museum Cardiff.

The precious rock is kept in a special airtight container filled with nitrogen to protect it from contamination. At 3.3 billion years old, it is considerably older than the most ancient Welsh rock, which is displayed alongside it - and a mere 702 million years old.

The moon rock is the most expensive item in the entire museum. Its value is based on the cost of going to the moon to get another piece. It is kept in a protective nitrogen environment, only NASA has a key to open the inner case.
