Caltech

Caltech is a small, collaborative community, where faculty, postdoctoral scholars, students, and staff from diverse backgrounds, cultures, and experiences live, work, and engage with one another. Together, they remain committed to setting the example of what its intertwined missions of research and education can accomplish.

Caltech is an integral part of Pasadena. Together with JPL, we are the city's largest employer and a source of programs that benefit our neighbors: teachers, businesses, families, cultural centers, and government.

NASA’s next generation starts here.  Across the 2025–26 academic year, Caltech was JPL’s top feeder school for internships. The connection runs deep. More than two decades before NASA was created, Caltech students and researchers were conducting daring rocketry experiments side-by-side in the Arroyo Seco. This work helped pave the way for Caltech’s founding of JPL in 1936. Now, a new generation of Caltech interns is carrying that legacy forward
Meet Ashwin Vasavada (PhD 98), a Caltech graduate and project scientist for NASA’s Mars Curiosity rover. As part of The Explorer Class, we’re introducing extraordinary people at Caltech and JPL who make possible some of NASA’s, and humanity’s, most ambitious and technically demanding missions. These are explorers pushing the boundaries of what we know, what we can build, and what we dare to imagine. #CaltechJPL #Mars #SpaceExploration

During a total solar eclipse, the Earth, Moon, and Sun align. You won’t be able to see it in California today, but you can hear Caltech postdoc Gabriel Muro talk about how eclipses are a powerful tool for scientists to test new instrumentation, models, and techniques. #Eclipse2026 #TotalSolarEclipse What do you want to #AskCaltech?

Ever wanted to take a class from the scientist who “killed Pluto”? Now is your chance. The Science of the Solar System (SciSolSys), taught by Mike Brown, is an online introduction to planetary science available to take on Coursera (quizzes included) or to watch on YouTube—both free! It is designed as a nine-week long course exploring the solar system around us through a strong scientific lens. Completing this course will give you an understanding of the way the scientific process is used to understand and investigate the planets and other bodies around us. Learn more about it through the link in our bio. #Caltech #MikeBrown #SolarSystem #FutureOfSTEM #PlanetaryScience
