ExoPAG 23 (January 5-6, 2021)

This finding was drafted by the ExoPAG Executive Committee and presented to the ExoPAG at a Community Forum on December 15, 2020. With community input, revisions were made, and the finding was presented to the community for an on-line vote (March 1-10) because our business meeting at ExoPAG 23 was cancelled due events at the Capital. The finding was approved, and the finding and vote outcome was shared with APD Director Paul Hertz.

Finding #1: On the value of investing in interdisciplinary exoplanet science of scale over longer periods of performance.

"Whereas exoplanet science is inherently interdisciplinary, requiring expertise in heliophysics, earth science, planetary science, and astrophysics, among other disciplines, as well as deep and broad knowledge in theory, computation, observation, experiment, statistics, and instrument development, and whereas interdisciplinary research can require longer timeframes and greater resources to take full advantage of such diverse expertise within a collaboration, and whereas existing opportunities of scale that permit longer periods of performance to support interdisciplinary research teams are restricted to areas that specifically address the goals of the astrobiology program,

We find that longer term programs of scale (e.g. five year periods of performance and up to several million USD awards) would enable NASA to rapidly and efficiently address linked sets of the Exoplanet Exploration Program Science Gaps, for example 01-03, 02, 04-06, and 07-08-10, which contribute significantly to achieving NASA’s strategic goals, provided that such new opportunities did not come at the expense of existing programs which are also extremely valuable to help NASA achieve its strategic goals."

ExoPAG 21 (January 3-4, 2020)

The following findings were drafted by the ExoPAG Executive Committee, shared for discussion with the ExoPAG at the 21st ExoPAG Meeting January 3-4, 2020, and approved with the outcomes of each vote reported below. The findings and vote outcomes were shared with the NASA Astrophysics Advisory Committee (APAC) and APD Director Paul Hertz.

Finding #1: On the need to invest in databases to support programs related to achieving NASA’s strategic goals.

+ more

Whereas candidate missions plan to observe a limited number of nearby target stars, and whereas each mission has different criteria for selecting targets, and whereas a comprehensive catalog of the physical and environmental properties of all nearby stars and their planetary systems could make future surveys more efficient (e.g. understanding the multiplicity or composition of potential targets given apparent correlations between these properties and exoplanet demographics), perhaps more cost effective, and probably lower risk,

We find that assembling such a catalog can potentially save significant NASA resources, and would help candidate missions address ExoPAG Science Gaps 06, 07, and 10, which contribute significantly to achieving NASA’s strategic goals.

Finding #2: On the topic of ExoPAG providing input to other Divisions and programs on topics related to Exoplanets.

+ more

Whereas ExoPAG is inherently an interdisciplinary research community whose expertise and interests are relevant to some programs covered by the Earth Science, Heliophysics, Planetary Science, and Astrophysics Divisions, and whereas some programs administered by NASA, such as XRP, draw resources from multiple divisions, and whereas new initiatives, such as the Lunar Development and Analysis Program, could benefit from input from communities such as ExoPAG,

We find that multiple audiences would benefit from exposure to reports and findings generated by the ExoPAG to help shape their research programs, and that ExoPAG could benefit from receiving relevant reports and findings from other Program Analysis Groups.

Finding #3: On the topic of evolution in the Exoplanet Research Program (XRP) outcomes and funding lines.

+ more

Whereas the Exoplanet Research Program (XRP) has been one of NASA’s most successful R&A programs in addressing critical elements of NASA’s strategic goals specifically related to exoplanet science, and whereas the research community is growing and dynamic having the highest rate of new NASA R&A PIs of any other program, and whereas the success rate has dropped to the lowest rate of any other R&A program (with the exception of the FINNEST fellowships), and whereas the funding mechanisms, as well as the scope of the calls, are expected to evolve in the coming year as other divisions participate,

We find that close monitoring of the program, scrutiny of success rates and programmatic balance, along with feedback from and communication with the community might help avoid unintended consequences during this evolution.
