Space based studies of UHE neutrinos

The Universe at Ultra-High Energies (UHE) above E > 6 × 10 19 eV is largely unexplored. In this paper we focus on the search for UHE neutrinos. After briefly summarizing the science rationale for neutrino studies at UHE, we describe the Extreme Universe Space Observatory (EUSO) onboard the Japanese Experiment Module (JEM) of the International Space Station.
