Planetary Geosciences Undergraduate Major

Welcome to the new Planetary Geoscience major, being jointly offered by the top-ranked departments of Geosciences and Planetary Sciences.  The University of Arizona has long been a leader in the field of planetary geoscience, and now you can be a part of the action! This program is for you, whether you aspire to lead the next big NASA mission to another planet, to be one of the next generation of astronauts to explore the Moon or Mars, or to work in one of the many fields that intersect with planetary science including space resources, space policy, science journalism, education, and more.  The Planetary Geoscience major builds on a foundation of math, physics, and chemistry; establishes core knowledge and skills through a set of geoscience courses; advances through upper-level planetary science classes; and culminates in a capstone research or field experience.
