ASU has been selected by the National Science Foundation (NSF) as the new host university for the EarthScope National Office. The EarthScope program centers on exploration and discovery of the 4-D structure and evolution of the North American continent, but also encompasses studies of Earth structure and dynamics throughout the planet. The rotating, university-based national office, established through a four-year nearly $2.4 million grant, facilitates scientific planning and coordinates education and outreach efforts for the EarthScope community.

You might think that Earth science and space exploration have little in common. But Arizona State University is marrying the research fields into a single school, creating a pathway for students to learn engineering and scientific skills and eventually develop new technologies to discover more about our Earth and other planets.
