One of the primary means by which CAPS addresses its twin roles is by monitoring the progress in implementation of the recommendations of the most recent planetary science decadal survey, Vision and Voyages for Planetary Science in the Decade 2013-2022 (hereafter, V&V) .1 Planetary science decadal surveys evaluate the state of the field, identify the most important scientific questions and themes, and prioritize missions and activities for the decade in question based on scientific merit, technical feasibility, and anticipated cost.

This date is sufficiently late in the decadal cycle that NASA asked CAPS to evaluate any changes in scientific understanding and external factors,4 such as programmatic developments and/or technological advances, that would warrant a reconsideration of four of the identified New Frontiers mission themes -- Ocean Worlds, Trojan Tour and Rendezvous, Io Observer, and Lunar Geophysical Network.5 Examples of programmatic developments include NASA's selection of the Lucy multiple-Trojan-flyby mission in the small-mission-class Discovery program, the 3 House Report 114-130 accompanying Commerce, Justice, Science, and Related Agencies Appropriations Bill, 2016, p. 59, https://congress.gov/114/crpt/hrpt130/CRPT-114hrpt130.pdf.

The phasing of the various missions discussed in this report relative to the completion of the next planetary science and astrobiology decadal survey and the release of the AO for NF5 is outlined in Table 1.1. STATEMENT OF TASK Against the backdrop described above, PSD Director Lori Glaze requested that CAPS address the following task: In keeping with its charge to monitor the "implementation of the decadal survey's recommended scientific and technical activities," and, specifically, to draft short reports addressing topics relating to the "scientific impact of a change in the … programmatic sequencing of one or more of the survey recommended activities … and the scientific impact of a course of action at a decision point described in the survey report," the Committee on Astrobiology and Planetary Sciences will draft a short report that will answer the two questions below for the following four New Frontiers targets: Ocean Worlds, Trojan Tour and Rendezvous, Io Observer and Lunar Geophysical Network: 1.

, and the statement of task for this study. Chapter 2 -- Addresses the first question in the committee's statement of task by discussing whether the scientific, technical, and programmatic context for spacecraft missions addressing the Ocean Worlds, Trojan Tour and Rendezvous, Io Observer, and the LGN mission themes have changed since the release of the V&V planetary science decadal survey in 2011.
