The Extreme Universe Space Observatory on a Super Pressure Balloon II Mission
(EUSO-SPB2) is a precursor for a next generation space observatory for
multi-messenger astrophysics. The EUSO-SPB2 instrument will measure PeV and
EeV-scale cosmic rays, 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 the Antarctic Impulse Transient
Antenna (ANITA) reported. The payload, now in the design and fabrication stage,
features a pair of optical telescopes that have 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 discuss the science and mission, and the current
status.
