This database is updated annually and indexes technology development projects managed by the Physics of the Cosmos (PCOS), Cosmic Origins (COR), and Exoplanet Exploration (ExEP) Program Offices. The portfolio includes information mostly about our Strategic Astrophysics Technology (SAT) and direct-funded projects and some other Astrophysics funded projects managed by one of the Program Offices.

Astrophysics is the science that studies the universe. NASA's Astrophysics Division funds and manages missions and studies that seek to broaden our understanding of our place in the universe. This work addresses three big questions: How does the universe work? How did we get here? Are we alone? These three themes are managed by the PCOS, the COR, and the ExEP Programs, respectively. The breadth and scope of astrophysics can be summed up by simply saying that if it is located outside our Solar System, we are interested in studying it. This portfolio includes technology development projects within the purview of the three Program Offices.
