... . The remaining three PI-led programs are shown in Figure 1.2: Discovery, with opportunities for solar system exploration, extrasolar planet searches, and astrobiology subdisciplines; New Frontiers, for larger solar system exploration missions in designated science areas; and Mars Scout, which is dedicated to Mars exploration goals.

... National Research Council decadal surveys, for which representatives of the astronomy and astrophysics, planetary sciences, and solar and space physics communities are convened to achieve consensus on priorities for future science research and missions in the particular discipline. Core missions, such as the Solar Terrestrial Probes4 in the Sun-Earth Connections discipline, Cassini in the solar system exploration discipline, and the great observatories (Hubble Space Telescope, Compton Gamma Ray Observatory, Chandra, and Spitzer5)

... The number of PI-led mission programs has continued to grow. The two newest mission lines, Mars Scout7 and New Frontiers, were spawned by a combination of scientific community advocacy8 and recognition of the potential for achieving some identified high-priority exploration goals sooner and at considerably lower cost than agency-managed core missions.

... In particular, reviewers must take into account the cost caps while determining, within the limits of the information provided, the ability of the PI and proposing team to successfully complete the mission given the organization and approach they offer. On the other hand, because the PI-led approach stresses the development of an entire mission concept, through science data analysis, the selected PI team is motivated to trade effectively between science, mission design, schedule, and cost.
