2 See NASA, 2020, "Announcement of Opportunity, Draft Earth Venture Mission-3, Earth System Science Pathfinder Program," NNH20ZDA006J, April 10, which states, "For this solicitation, NASA will prioritize consideration of proposals that address the questions laid out in the 2017 Earth science decadal survey and will use the classification of the question being addressed as a guide for consideration." Observables that were deemed to be considered for Explorer Class (ES) Investigations and those listed in Table 3.5 as "Other ESAS 2017 Targeted Observables, not Allocated to a Flight Program Element" will be considered here as there are no assurances that all of these particular observables would be addressed in the near future." Also stated in the 2021 EVM-3 AO is the following: "For this EVM-3 solicitation, NASA places a strong emphasis on research and innovation for Earth system science issues, especially those observational objectives given high priority in the 2017 DS, while expecting appropriate attention to applicationsoriented aspects to further the overall value of the mission." See NASA, "Earth Venture Mission-3 (EVM-3)

Furthermore, those science targets are themselves the result of a prioritization from a still larger set of science priorities highlighted in the survey report. RECOMMENDATION 3.1: To encourage consideration of a wider set of ideas benefiting Earth sys tem science, NASA's Earth Science Division should, in future Earth Venture solicitations, emphasize that science priorities of potential interest encompass the full range of science priorities in the 2017 National Academies of Sciences, Engineering, and Medicine decadal survey Thriving on Our Changing Planet: A Decadal Strategy for Earth Observation from Space.

The success of SpaceX and a number of other recent private industry startups targeting the small satellite market has dramatically changed access to low Earth orbit (LEO) by reducing cost, increasing competition, and providing a broadening set of launch capabilities.

LSP engages missions as requested, but not before critical design review when instrument details and schedules are sufficiently well known to negotiate launch contracts. Because of this, it is not clear how risk is assessed by the selection committee when proposed launch services are significantly different from NASA LSP experience.

and deployable mesh antenna technology, which was a miniaturization initiative at NASA JPL and followed by ESTO's In-Space Validation of Earth Science Technologies award to demonstrate this measurement from space. The TEMPEST-D radiometer (5 channels from 89-182 GHz)

With more small, cost-effective missions possible, additional agencies, as well as the commercial sector, will be launching an increasing number of small Earth observing satellites. In developing EV solicitations, the committee encourages NASA to clarify the role of the increasing availability of third-party data on surface monitoring, weather, and climate prediction.
