JEM-EUSO, "Joint Experiment Missions for Extreme Universe Space Observatory" on board the International Space Station (ISS), is the first space mission devoted to the exploration of the outermost bounds of the Universe through the detection of the ultra high energy cosmic rays and neutrinos.
The experiment will utilize the Earth atmosphere as a giant detector.
The most energetic particles coming from the Universe are one of the most challenging issues in astroparticle physics. The very existence of such energetic particles and of neutrinos of comparable energy raises fundamental scientific questions in connection with their origin and propagation in the interstellar and intergalactic spaces.
Sitting on the ISS and looking downward the Earth, JEM-EUSO will detect the extreme energy cosmic rays particles observing the fluorescence signal produced during their passage in the atmosphere; the Cherenkov signal, diffused when the shower hits the ground or the top of a cloud, will also be imaged. IASF-Palermo has been strongly involved in the definition, design and realization of the original EUSO proposal. Nowadays a considerable part of the institute's efforts aim at researches in methods and methodologies for images and data analysis in the framework of JEM-EUSO project.
