Planning for the 2020 Decadal Survey
The next Decadal Survey in Astronomy and Astrophysics will be conducted by the National Research Council (NRC) in response to a charge set by NASA and NSF, and possibly DOE. Nominally this survey will be carried out in the years 2018-2020.
One of the important tasks of the 2020 Decadal Survey will be to prioritize large missions to follow JWST (the highest priority large space mission of the 2000 Decadal Survey) and WFIRST (the highest priority large space mission of the 2010 Decadal Survey). To enable this prioritization, NASA will provide information on several candidate large mission concepts for consideration by the 2020 Decadal Survey Committee.

The 2020 Decadal Survey Committee will consider a broad range of activities in addition to large space missions; these activities will certainly include medium-size, or probe-class, space missions. This white paper only addresses the plans for providing information to the 2020 Decadal Survey Committee regarding large mission concepts. No decision has been made by NASA at this time on how to provide input to the 2020 Decadal Survey Committee regarding probe-class missions, technology development, or other programmatic areas.
The large mission concept studies will be identified and announced in time for proposals addressing technology needs to be submitted in March 2016 to the APRA and SAT elements of ROSES-15.
The Astrophysics Program Offices at GSFC (Cosmic Origins/Physics of the Cosmos Program Office) and JPL (Exoplanet Exploration Program Office) will support the PAG activities in their program areas including support for workshops, communication, and reports.
