The Extreme Universe Space Observatory on a Super-Pressure Balloon II Mission

The Extreme Universe Space Observatory on a Super Pressure Balloon II Mission (EUSO-SPB2) will measure PeV and EeV scale cosmic rays, study optical backgrounds that could mimic tau neutrino interactions in the Earth's limb, and search for optical signatures consistent with the upward-going candidate events that Anita reported. EUSO-SPB2 is also a precursor for a next generation space observatory for multi-messenger astrophysics. The EUSO-SPB2 payload, now in the design and fabrication stage, will feature a pair of optical telescopes with 1 meter diameter apertures. The Fluorescence Telescope will have sensitivity in the UV to target extensive air showers at EeV energies. The Cherenkov Telescope will have UV/VIS sensitivity to target Cherenkov emission from air showers at PeV energies. The planned launch date is 2022. We will discuss the mission, the instrument, and the current status.
