Description
The JEM-EUSO mission explores the origin of the extreme energy
comic-rays (EECRs) above 1020 eV and challenges to the limit of the
basic physics, through the observations, of their arrival directions and
energies. It is designed to observe more than 1,000 events of EECRs
above 7×1019 eV in its five-year operation with an exposure larger
than 1 million km2 · sr · year. The super-wide-field (60
degrees) telescope with a diameter of about 2.5m looks down the
atmosphere of the night-side of the earth to detect near UV photons
(330-400nm, both fluorescent and Cherenkov photons) emitted from the
giant air-shower produced by an EECR. The arrival direction map with
1,000 events naturally tells us the origin of the EECRs and allows us to
identify the EECR sources to known astronomical objects. The comparison
among the energy spectra of the spatially resolved individual sources
will clarify the acceleration/emission mechanism, and also finally
confirm the Greisen-Zatse'pin-Kuzmin process for the validation of
Lorentz invariance up to ˜ 1011 . Neutral components (neutrinos
and gamma rays) can also be detected as well, if their fluxes are high
enough. The JEM-EUSO mission is planned to be launched by a H2B rocket
about 2015 and transferred to ISS by H2 Transfer Vehicle (HTV). It will
be attached to the external experiment platform of "KIBO" which
completed July 2009 by STS-127 mission of the space shuttle. The first
flight of HTV by H2B rocket was successfully done in September and
October 2009.
