Description
JEM-EUSO will be the first observatory to explore from space the
universe at ultra-high energies. Hosted on the JEM platform on board the
ISS, it will use an innovative refractive optics and sophisticated focal
surface to observe the UV fluorescence light emitted, in the 320-400 nm
band, by extensive air showers generated by primary particles interacting
in the atmosphere. The telescope will achieve an unprecedentedly large
effective aperture and a very uniform exposure in declination over
the whole celestial sphere, which are beyond the capabilities of present
ground-based observatories. The main scientific objectives will include the
measurement of the energy spectrum at the highest energies of the cosmic ray
spectrum, including the yet unexplored region of a possible recovery, and anisotropy studies
with large statistics which will allow for the possibility of
point-source charged-particle astronomy. In this presentation,
the status of the mission, its scientific potential and performance will be reviewed.
