Study with a school that’s out of this world
The School of Earth and Space Exploration focuses on exploring planet Earth and the universe beyond. We break boundaries by combining the studies of Earth and space science to answer today’s most pressing questions in science. Many researchers are experienced principal investigators or co-investigators on orbiters and rovers studying Mars, the moon, asteroids and Jupiter’s moon Europa. Other researchers are studying the Milky Way, the origins of life on Earth, engineering systems design and more to set the stage for a new era of exploration.
