Status of the Extreme Universe Space Observatory on a Super Pressure Balloon 2

The Extreme Universe Space Observatory on a Super Pressure Balloon 2 (EUSO-SPB2) mission will make new measurements from suborbital space as a precursor for future space missions that aim to identify the sources ultra-high energy cosmic rays and very high energy neutrinos. The EUSO-SPB2 payload features two 1m diameter aperture telescopes. The Fluorescence Telescope (FT), which will point down, will record fluorescence light from cosmic ray EASs with energies above 1EeV in its field of view of 36 by 12 degrees. The Cherenkov Telescope (CT) features a silicon photomultiplier camera system with a field of view of 12 by 6 degrees that will point near the Earth’s limb. Below the limb, the CT will follow up on alerts of binary black hole merger, ??binary neutron star merger, gamma-ray burst, and tidal disruption event candidates by searching for Cherenkov emission from PeV-scale EASs induced by tau neutrinos. When tilted above the limb, the CT will measure Chernkov light from direct cosmic rays. EUSO-SPB2 is on track for launch on a NASA super pressure balloon payload in April of 2023 from Wanaka NZ. I will report on the status of the project, the desert field tests of the telescopes, and my contributions to the project.
