From discovering planets beyond our solar system and analyzing samples returned from asteroids, to understanding the large-scale structure and evolution of the cosmos, Penn State researchers are helping to address fundamental questions about the universe - How did life begin? What is humanity's future in space? What are the origins and fate of the universe? - while also leading some of today's key advancements in space-related innovation and instrumentation.
"Penn State's strength in space science comes from the depth of our long-standing scientific leadership and the breadth of disciplines we unite to tackle complex questions," said Tracy Langkilde, Verne M. Willaman Dean of the Eberly College of Science. "Our space science story is one of quiet power - rooted in interdisciplinary excellence and a relentless drive to explore."
For the second year in a row, Penn State ranks No. 20 in the world (No. 13 nationally) for space science research, according to U.S. News & World Report's 2026-27 "Best Global Universities," released on July 16, with additional top-100 world rankings in related research areas.
In addition to Penn State's research strength in astronomy, geosciences (ranked No. 31), physics (No. 40), materials science (No. 41), meteorology and atmospheric sciences (No. 65), engineering (No. 93), and other fields converge at the University to create a highly collaborative environment for space science. In separate U.S. News rankings, Penn State comes in at No. 9 in the U.S. for gravitation/cosmology/astrophysics ("Best Graduate Schools"), and No. 13 in the U.S. for aerospace engineering in both undergraduate ("Best Colleges") and graduate programs ("Best Graduate Schools").
An integrated approach
This integrated approach spans fundamental research, advanced instrumentation, student education, and national leadership in space exploration, according to Lee Kump, the John Leone Dean in the College of Earth and Mineral Sciences.
"Space science at Penn State takes a systems approach," Kump said. "Through collaboration among astronomers, astrophysicists and geoscientists, we strive to answer the question, 'What makes a habitable world?' through investigations of Earth's past and the search for unambiguous signatures of life on other planets."
That approach helps position Penn State to make meaningful contributions by expanding the boundaries of human knowledge for tomorrow and making visible, applied impact today, while also preparing students for leadership in a rapidly evolving space economy, Langkilde added.
According to NASA, space science activities in Pennsylvania supported 1,749 jobs and generated $409 million in economic output in fiscal year 2023, with Penn State at the heart of this ecosystem.
Later this month, alongside industry partners Katalyst Space and Northrop Grumman, Penn State will be an integral partner for a high-profile mission to boost NASA's Neil Gehrels Swift Observatory, for which the Eberly College runs mission operations.
In a Q&A, Donald Schneider, distinguished professor and, as of July 1, interim head of the Department of Astronomy and Astrophysics, and Christopher House, professor of geosciences and director of the Pennsylvania Space Grant Consortium and of the Penn State Consortium for Planetary and Exoplanetary Science and Technology (CPEST), discuss what distinguishes Penn State's space science programs and how their work contributes to scientific discovery and societal impact.
