The Probe Of Extreme Multi-Messenger Astrophysics (POEMMA) is designed to
observe cosmic neutrinos (CNs) above 20 PeV and ultra-high energy cosmic rays
(UHECRs) above 20 EeV over the full sky. The POEMMA mission calls for two
identical satellites flying in loose formation, each comprised of a 4-meter
wide field-of-view (45 degrees) Schmidt photometer. The hybrid focal surface
includes a fast (1 μs) ultraviolet camera for fluorescence observations
and an ultrafast (10 ns) optical camera for Cherenkov observations. POEMMA will
provide new multi-messenger windows onto the most energetic events in the
universe, enabling the study of new astrophysics and particle physics at these
otherwise inaccessible energies.Comment: 8 pages, 6 figures, presented in 36th International Cosmic Ray
