... Some might be executable as a small mission, while others might require flagship-class capabilities. Examples of potential approaches to the exploration of these environments that could inform Mars science priority planning for the next decade include the following: • Multiple rovers or other mobile platforms built simultaneously with defined payload interfaces; • Mars polar climate missions akin to those mentioned in Vision and Voyages; 33 and • Landed spacecraft, appropriately prepared in light of planetary protection considerations, to search for potential biomarker at sites with possible recent surface or near-surface water.

... during Voyager 2's 1989 flyby in sharp relief. Logical follow-on missions that could be usefully studied in advance of the next planetary science decadal survey include a Ceres lander, a Pluto system orbiter, and Centaur and/or Kuiper belt object flybys.

... In an effort to optimize the science value of outer solar system exploration in the next decade, the feasibility of lower-cost flagship missions that, for example, combine elements of proposed Discovery and New Frontiers concepts, are worthy of study. The co-location of three high-priority targets -- Saturn, Titan, and Enceladus -- in the Saturn system provides a potential opportunity to accomplish significant science for multiple targets using a common spacecraft.
