Sample return missions have brought back about 382 kg of rock from nine localities on the lunar nearside (see right). These samples have shed new light on the formation of the Moon; how the lunar crust formed; and how the crust was subsequently modified by magmatic and volcanic episodes and impact bombardment.
In Manchester we are studying a range of Apollo and Luna samples to address the following lunar science investigations (see more details here):
- The petrological evolution of the lunar crust
- The volcanic history of Mare Crisium (Luna 24) and Oceanus Procellarum (Apollo 12)
- The impact and regolith history of the Apollo 16 highlands landing site
- Characterising the sources of lunar impactors
- The nature of polar volatiles
- The halogen history of the lunar surface and interior
We are activity involved in sharing our excitement about lunar samples to the wider public. You can read lunar science news through the Earth and Solar System blog and come along to our public engagement events (watch the Earth and Solar System twitter feed or facebook group for event news) to hold a piece of the Moon!
