Aside from the meteorites that fall to Earth haphazardly, direct analysis of the materials of the solar system has required explorers–both human and robotic–to collect and return samples from the Moon, comets, asteroids, and one day other planets. The four lectures in this year’s series will spotlight the sample return missions that have helped us better understand the origin and evolution of the Earth and other planets.

This lecture series is made possible by the generous support of Aerojet Rocketdyne, an L3Harris Technologies company, and United Launch Alliance.
