Our last Zoom talk, which promises to be very interesting is by Dr Mike Simms who is Curator of Geology at the National Museums of Northern Ireland:
Meteorites: Messengers from the Solar System
Billions are spent sending people and machines to examine other worlds in our Solar System, yet we have samples from more than 100 of these worlds that arrived here for free. They are meteorites. Most are from asteroids, remnants of planetesimals that no longer exist as intact entities, and they can tell us about the formation and early history of our Solar System. Some are from the Moon or Mars and augment the information obtained by astronauts and robots. Most meteorites are composed of familiar minerals, although often in a form or context not found on Earth, with just a few minerals known only from meteorites. This talk will provide an overview of the different types of meteorites, the minerals that they contain, how they formed, and what they can tell us about the Solar System beyond our own planet.
