... Since mission planning for the latter part of the 15-year interval is currently underway in both the Office of Space Science and the Office of Earth Science, and since important elements of these offices' programs will be accomplished through competitive selections in the community-based Explorer, Discovery, and Earth System Science Pathfinder lines, a complete allocation of science objectives to particular missions cannot be made at this time. For the later part of the 15-year period, your assessment may address generic mission ideas presented in the strategic plans.
