Technology Gap List

Click here for the NASA Astrophysics Division Technology Gap List (2022)

The motivation and objectives of the ExEP Technology Program are summarized in the Technology Gap List: the list serves to identify where technology development is needed. A technology gap is defined as the difference between what has been done (or is known) today relative to what is needed in order to implement a future mission, and candidate technologies are ones that potentially close the gap.

The Astrophysics Biennial Technology Report is a joint technology report from the three Astrophysics Program Offices -- Physics of the Cosmos (PCOS), Cosmic Origins (COR), and Exoplanet Exploration Program (ExEP), and provides an overview of the technology needs of NASA's Astrophysics Division.
