Standing Committee

Committee on Solar and Space Physics (CSSP)

The Committee on Solar and Space Physics (CSSP) provides an independent, authoritative forum for identifying and discussing issues in solar and space physics with the research community, the federal government, and the interested public. The committee supports scientific progress in solar and space physics (heliophysics) by providing advice to the federal government on the implementation of decadal survey recommendations.

Request for Information on the Heliophysics Digital Resource Library and the Community Coordinated Modeling Center

Update

At the request of NASA, the Committee on Solar and Space Physics will author a short report on the readiness of the Heliophysics Digital Resource Library (HDRL) and the Community Coordinated Modeling Center (CCMC) to support the next decade of heliophysics science from the user's perspective. The CSSP seeks input from providers and users of HDRL and/or CCMC. Initial responses would be appreciated by November 18, 2026, and the form will remain open until November 30, 2026.

Statement of Task

The National Academies of Sciences, Engineering, and Medicine (NASEM) will appoint the Committee on Solar and Space Physics (CSSP) to support scientific progress in solar and space physics (Heliophysics) and to assist the federal government in planning programs in these fields by providing advice on the implementation of decadal survey recommendations. The CSSP provides an independent, authoritative forum for identifying and discussing issues in solar and space physics between the research community, the federal government, and the interested public.
The CSSP's scope spans space-based and supporting ground-based research in support of scientific programs in solar physics, heliospheric physics, plasma physics, magnetospheric physics, aeronomy, physics of the upper atmospheres of Earth and other planets, solar-planetary interactions, and cosmic ray physics. The CSSP's scope also includes appropriate cross-disciplinary areas and consideration of budget and programmatic aspects of the implementation of the decadal survey.
The committee shall monitor the progress of implementing the priorities in the most recent decadal survey for the most important scientific and technical activities in that report and recommendations in the subsequent mid-decadal review report.
When agreed to by a sponsor and as approved by NASEM in accordance with its procedures, the committee may write consensus reports or an individual member, set of members and outside experts as needed, and staff of the committee may write non-consensus issue papers to assess progress on the implementation of the decadal survey's recommended scientific and technical activities. Consensus reports will be based on evidence gathered by the committee. Issue papers include evidence gathered by the authors on the status of and key elements shaping an issue, examining and summarizing the research or evidence base, examining existing practices on a key issue, and/or providing technical assessments of strategies and priorities. The reports and issue papers may address key strategies being pursued by the agencies and the status of agency actions that relate to the state of implementation. The reports and issue papers may also highlight scientific discoveries and engineering and technical advances relevant to progress on the science objectives identified in the most recent decadal survey and in addition may focus on one or more of the following types of issues:

  • The scientific impact of a change in the technical and engineering design, cost estimate, schedule, or programmatic sequencing of one or more of the survey-recommended activities;
  • The impact of a scientific advance on the technical and engineering design, schedule, or programmatic sequencing of one or more survey-recommended activities;
  • The scientific impact of a course of action at a decision point described in the survey report and recommended therein as being suitable for consultation with an independent decadal survey implementation committee;
  • The scientific impact of implementing recommendations from the mid-decadal review and other relevant NASEM reports.

Comment on Provisional Committee Appointments

Viewers may communicate with the National Academies at any time over the project's duration. In addition, formal comments on the provisional appointments to a committee of the National Academies are solicited during the 20-calendar day period following the posting of the membership and, as described below, these comments will be considered before committee membership is finalized. We welcome your comments (Use the Feedback link below). Please note that the appointments made to this committee are provisional, and changes may be made. No appointment shall be considered final until we have evaluated relevant information bearing on the committee's composition and balance. This information will include the confidential written disclosures to The National Academies by each member-designate concerning potential sources of bias and conflict of interest pertaining to his or her service on the committee; information from discussion of the committee's composition and balance that is conducted in closed session at its first event and again whenever its membership changes; and any public comments that we have received on the membership during the 20-calendar day formal public comment period. If additional members are appointed to this committee, an additional 20-calendar day formal public comment period will be allowed. It is through this process that we determine whether the committee contains the requisite expertise to address its task and whether the points of views of individual members are adequately balanced such that the committee as a whole can address its charge objectively.
