Figure 1-2. Artistic illustration of the JEM-EUSO telescope attached to the Japanese Experiment Module of the International Space Station, under nadir (left) and tilt (right) mode of observation.

The JEM-EUSO telescope can reconstruct the incoming direction of the EECRs with accuracy

better than few degrees. Its observational aperture of the ground area is a circle with 250 km

radius, and its atmospheric volume above it, with a 60° FoV, is ~1 Tera-ton or more. The target

volume for upward neutrino events exceeds 10 Tera-tons. The instantaneous aperture of JEM-

EUSO is larger than the Pierre Auger Southern Observatory by a factor ranging from 65 to 280,

depending on its observation mode (nadir or tilted, Fig.1-3).

JEM-EUSO, planned to be attached to JEM/EF of ISS, will be launched in the JFY 2016 by

H2B rocket and conveyed to ISS by HTV (H-II transfer Vehicle).
