... E Panel Missions Not Selected for Additional Study INTRODUCTION As described in Appendix C, each of the survey's six panels reviewed the SDT and PMCS reports and assessed those concepts proposed by the community in white papers and prior proposals. Then the panels identified 18 additional large- and medium-class mission concepts that could address key scientific questions within their respective purviews.

... Nature of Study Requested The panel requested that a rapid mission architecture (RMA) study (i.e., Concept Maturity Level CML ~1-3)

... Implementation This concept was proposed as a large-class mission and implemented via an orbiter, a large lander, and a fixed-altitude aerial platform. The orbiter is in a high, equatorial, retrograde orbit (cf.

... • Determine the composition and history of Pre-Noachian and Noachian martian units, volcanic, sedimentary, and groundwater/hydrothermal; • Determine the suites of habitable conditions present on early Mars and what controls observed variability over space and time; • Evaluate the surface inventory of water and other volatiles, including change with time by isotopic and mineralogical/chemical analysis; and • Measure, if feasible, the ages of rock units and surfaces. Implementation This concept was proposed as medium-class mission and implemented via a rover using an upgraded air bag landing system and having greater operating autonomy than its MER predecessors.

... INTERSTELLAR OBJECT RAPID RESPONSE MISSION Origin and Goals This concept was proposed by the Panel on Small Solar System Bodies to investigate the acquisition of time-critical spacecraft observations of novel solar system phenomena. The discovery of the first interstellar objects -- 1I/'Oumuamua in 2017 and 2I/Borisov in 2019 -- transiting the solar system was one of the key scientific result of the last decade.

... Implementation This concept was proposed as a medium-class, 2-to-10-m dedicated telescope with ultraviolet/visible/near-infrared imaging and spectroscopic capabilities, optimized for cadence and survey observations of transient, evolving, and interacting processes in the solar system. Desirable characteristics include the following: ability to operate at solar elongations ≥30°; a tracking capability of ≥216"/hr; instrument field of view of 60"; and minimum lifetime of 7 years.
