However, owing to a variety of external circumstances (as discussed in Chapter 2) and growth in other program elements, what had been stipulated to be the Future Missions Wedge that would support decadal survey flight program priorities, was essentially consumed.

Recommendation: NASA's Earth Science Division should take full advantage of its meetings with National Academies' Committee on Earth Science and Applications from Space to seek feedback on its implementation plans to facilitate more timely decisions and maintain alignment with the Earth science and applications from space decadal survey recommendations, even as its budget fluctuates from year to year. 3 Recommendations 3.2 and 4.6 refer to decision rules in Chapter 4 of the 2017 decadal survey report (NASEM 2018)

These missions were to be managed within cost caps so as to not impact other elements of the flight program. After the report's release, NASA organized study teams for each Targeted Observable assigned to the Designated program element.

. Surface Biology and Geology The decadal survey recommended NASA develop a mission to address the SBG Targeted Observable with a maximum NASA development cost of $650 million (FY 2018)

Mass Change The decadal survey recommended NASA develop a mission to ensure continuity of the Mass Change Targeted Observable with a maximum NASA development cost of $300 million (FY 2018)

Finding: The mission architecture for addressing the SDC Targeted Observable following the NISAR mission remains undefined because no options identified to date meet the cost cap while also address ing the decadal survey's priority science and applications objectives. Earth System Explorer The decadal survey recommended a new Earth System Explorer program element consisting of competitive opportunities for cost-capped, medium-size instruments and missions to address specific decadal survey priority observables.

From page 42... ...
Incubation In recognition that some Targeted Observables, despite their high priority, lacked sufficient maturity to be ready for low-risk flight implementation, the decadal survey recommended a new Incubation program element. For each Targeted Observable in the Incubation program element, the report calls for "a coordinated program of strategic investments in technology, research, modeling, or data system development would be developed by NASA toward maturing the overall measurement concepts" (p.

Surface Topography and Vegetation The decadal survey recommended the STV Incubation program to advance the ability to obtain high- resolution global topography, including bare-surface land topography, ice topography, vegetation structure, and shallow water bathymetry. An STV study team was competitively selected and has held five meetings (workshops, breakouts, and an American Geophysical Union town hall)

Yet, NASA's decision to proceed with the Landsat Next program was made without advice from the National Academies or other appropriate organizations on how to best address its impact on programmatic balance and other decadal survey priorities. Finding: Communication of Landsat's importance and budget priority is not well coordinated with communication of the larger NASA Earth science program's importance or budget.

The Sentinel Expansion Mission includes the Copernicus Hyperspectral Imaging Mission for the Environment (CHIME) , which will have two satellites with a similar spectral resolution and wavelength resolution (8.5 nm/band, 400 nm to 2500 nm)

The decadal survey made several recommendations regarding NASA's nonflight program elements. NASA has largely been responsive to such recommendations, in most cases maintaining the relative size of the various program elements roughly consistent with their long-term averages.

NASA's strategy in supporting the combined evolution of Earth system modeling and high-end computing is unclear, and the connection between flight programs and ESMs has not happened to the extent recommended in the decadal survey. One approach is to better integrate satellite data with ESMs (see Figure 3-5 as an example)
