Michael Freilich said that a modest investment in a critical review of the capabilities and plans of NASA’s international partners (in the Earth sciences) would probably be exceedingly useful to the decadal survey committee.

Lisa May—noting the different ways astronomy and planetary science handled their mission solicitation processes before and during their decadal surveys—said that more investigation is needed to find the balance between having NASA science divisions solicit mission studies from the community at large prior to a decadal survey versus the decadal survey committees sending mission concepts to NASA centers for on-demand studies. Hertz said that the peer review process for his division’s ROSES solicitation that occurred before the 2010 astronomy and astrophysics decadal survey served as a proxy for the community and did not amount to NASA pre-selecting missions on its own. May said that this exchange highlights some ideological differences among her colleagues about how best to handle this process, and she reiterated her call for more investigation into this issue.
