This database is updated annually and indexes technology development projects funded by the NASA Astrophysics Division. The portfolio includes information about the Strategic Astrophysics Technology (SAT), Astrophysics Research and Analysis (APRA), and Nancy Grace Roman Technology Fellowship (RTF) projects, along with other competed and direct-funded technology projects.

Astrophysics is the science that studies the universe. The 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 Physics of the Cosmos (PCOS), Cosmic Origins (COR), and Exoplanet Exploration (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. Astrophysics is humankind's scientific endeavor to understand the universe and our place it it.
