Professor Kevin McKeegan delivered the Robert M. Walker Distinguished Lecture titled “Sampling the Solar System: A Key in Our Quest to Understand Earth’s Origin and Evolution.”

Extraterrestrial samples can be studied in the laboratory in exquisite detail, revealing clues about their origins and, ultimately, about our own planet’s origin and evolution. We currently have materials from asteroids and comets, Mars (most likely) and Earth (of course), the Moon and even the Sun.

In this lecture, Professor Kevin McKeegan described some of these exotic materials, how we’ve come to obtain them, and what their analysis tells us about how our planetary system was formed 4.6 billion years ago.

This event was sponsored by the McDonnell Center for Space Sciences, Arts & Sciences.
