The Process

Once every ten years, the astronomical communities gather panels of experts to set community-wide priorities for the coming decade. These surveys are facilitated by the National Academies and commissioned by the Federal agencies. The most recent surveys started during 2019 and 2020.

Midterm Assessment

Near the half-way point of each decadal survey, the National Academies convenes a new panel of experts to evaluate progress on the priorities set forth by the current decadal survey. Only the progress on the priorities is considered, not the priorities themselves. Based on their assessment of the progress, the midterm review committee will make recommendations to the agencies and the community about how to proceed through the second half of the decade.

Survey of the Surveys: Lessons Learned from the Decadal Survey Process

The National Academies convened an ad-hoc committee to identify best practices of the decadal survey process. The resulting report also presented possible changes that could improve the process and identified challenges that surveys will likely face in the future.

Planetary Science

The current Planetary Science and Astrobiology Decadal Survey began convening in 2020 and will determine the scientific priorities and strategy for 2023-2032.

Astronomy and Astrophysics

Astro2020 has an expected release of January 2021, delayed from mid-2020 due to the coronavirus pandemic.

Heliophysics/Solar Physics

The midterm assessment of A Science for a Technological Society was published in 2020.
