single-step proposal selection process, as follows: NASA releases an AO based on the "standard" NASA AO template with very similar requirements, sections, page limits, reference documents, and so on, to other NASA AOs, including those for the Science Mission Directorate's (SMD's) Small Explorer (SMEX)

NOTES: Yellow shading denotes meetings at NASA Headquarters; blue and green shading is used to separate TMC activities from the science evaluation. AO = announcement of opportunity; EVI-4 = fourth Earth Venture Instrument solicitation; PEA = Program Element Appendix; TMC = technical, management, and cost.

FINDING 2.2: By using the same selection process as previous missions in the Earth System Science Pathfinder Program, which has minimal feedback between science and technical risk portions of the assessment, the EV selection process appears to favor lower risk missions independent of potential advances that were not explicitly part of the baseline science mission. For EVI-2, three Category III missions were referred to the NASA Earth Science Technology Office (ESTO)

• PI: Kelly Chance, Smithsonian Astrophysical Observatory • Instrument development: Ball Aerospace and Technologies Corporation • Project management: NASA Langley Research Center (LaRC) • Cost: $90 million • Competitive selection: 1 selection/14 proposals The TEMPO mission was selected in 2012 with the goal of measuring daily variations of ozone, nitrogen dioxide, and other key elements of air pollution from geostationary orbit.

science requirements are the minimum performance requirements necessary to achieve the minimum science acceptable for the mission. Baseline science requirements are the investigation performance requirements necessary to achieve the entire set of science objectives identified at the initiation of the mission.

GEDI was given an extension once its primary operational phase was concluded. A recent ROSES call resulted in the establishment of a competed science team, which began work in January 2021 with the objective of expanding the utility of GEDI science products by; for example, combining GEDI data with data from other sensors to advance scientific understanding of the carbon and hydrological cycles, biodiversity, and habitat dynamics.8 Other new science objectives include: applying machine learning for multi-sensor fusion; developing new biodiversity data products, including a waveform structural complexity index, and fusing data from GEDI and ICESat-2 for height, elevation, and biomass products.

The review board concluded that the spacecraft development was not successful in meeting identified performance standards and requirements and that continuation on this path would have entailed excessive risk to the MAIA mission.

• Instrument development: MIT LL • Project management: NASA LaRC • Cost: $30.2 million mission cost cap, exclusive of launch costs • Competitive selection: 2 selections/14 proposals Selected in 2016, the TROPICS mission will measure the temperature, humidity and precipitation of storms in the tropics. The mission will launch and deploy six dual-spinning 3U CubeSats10 carrying scanning 12-channel microwave radiometers into three separate orbital planes to enable the constellation to monitor tropical weather systems with unprecedented temporal frequency.

As a hyperspectral sensor, EMIT partially shares observing capabilities with NASA's designated Surface Biology and Geology mission that touches on a much broader array of Earth science questions. Thus, EMIT is an example of a mission with broader scientific potential than can easily fit within and be fairly evaluated in the EV proposal itself.

The GeoCarb mission is also behind schedule, and NASA has continued to fund GeoCarb even though it has greatly exceeded its cost cap. The three missions that have launched have met their initial science objectives in their entirety (CYGNSS and ECOSTRESS)

With this understanding, the HQ managers interviewed by the committee reported that the EV program has opened the door to new PIs. The managers also uniformly emphasized the importance of ensuring that mission proposal teams and implementing institutions embody sufficient experience -- either via collaboration with a NASA center or otherwise experienced implementation organization -- to implement the mission and to work with the spacecraft, instrument, and/or launch vendors effectively.
