NASA Probe Studies for 2020 Decadal Survey

  • NASA funding 10 Probe Class (below 1B$) Mission (18 mos) Studies in

PreparaAon for the 2020 Decadal Survey

  • PI responsible for the final report (due NLT Dec 2018)
  • NASA will submit these studies to the Decadal Survey
  • Decadal Survey CommiLee will have the opAon to prioriAze any of these mission

concepts, or recommend a competed line of Probes (similar to Explorers)

  • SelecAon based on Science Merit (cost, schedule)

To Address open ques9ons: What objects can accelerate par9cles to ~ 1020 eV?

How are they distributed in the sky? How does the composi9on of UHECRs evolve at the highest energies? How strong are magne9c fields in the intergalac9c medium? What is the flux of cosmogenic neutrinos?
