Kathryn McDermott: Martian Meteorites

Kathryn McDermott from the Open University’s Department of Physical Sciences gave us a brilliant and whistle-stop tour of meteors, meteoroids and meteorites, of the basic categories, where they come from, what their composition is, and how they are used to research the geology of the solar system and the possibiliies of extra-terrestrial life. We then had a chance to touch and pick up some samples, often very heavy because of their iron content, and could see formations like the fusion crust (see photo), formed by melting as the rock fell through our atmosphere. There was even a small piece from Mars!
