This cycle, the Program Offices assessed a total of 144 technology gaps. First, technologists and scientists from the three Program Offices allocated each gap to the Program whose science would be most impacted by closing that gap. Next, the gaps (whether new or carried over from 2019) were reviewed and edited by the relevant Program Analysis Groups (PAGs) as needed.
The three Program Offices each prioritized their gaps using a uniform set of criteria, weightings, and guidelines. During this process, many related gaps were merged, as appropriate. Technologists from the three Program Offices participated in each of the three prioritizations, to provide the most comprehensive knowledge base possible and to ensure uniformity in how gaps were treated across the three Programs. Finally, the three lists were merged into the final joint Astrophysics Technology Gap Priority list of 57 gaps.
