Astronomy and Physics

The Astronomy and Physics Directorate (APD) formulates, develops, and operates state-of-the-art space missions and instruments in astronomy and fundamental physics, addressing the questions: “How did the Universe begin and how has it evolved?”; “How does the Universe work?”; and “How has life come to be?” The Directorate nurtures a vibrant and diverse community of scientists, technologists, and engineers with expertise spanning the wide range needed to answer these key questions. The Directorate is also responsible for JPL’s role in NASA Heliophysics projects.

APD also manages JPL’s National Security Program Office, supporting our nation’s goals in security and intelligence with the Lab's technological and engineering capabilities, and returning to NASA enhanced capabilities and technologies developed in that work.
