The Mini-EUSO (Extreme Universe Space Observatory) is a small UV telescope to be placed inside the Zvezda module of ISS in 2017, as a part of the work of the JEM-EUSO collaboration. The Mini-EUSO instrument will be equipped with one full original JEM-EUSO Photo-Detector-Module (PDM), an optical system made of two Fresnel lenses (25 cm in diameter) and a data acquisition system. The Mini-EUSO instrument serves as a pathfinder towards the goals of the full JEM-EUSO mission: to place a large instrument on the outside of ISS to study Ultra-High Energy Cosmic Rays (UHECR) with energies of E > 3×1019 eV. This can be achieved by measuring the light in the UV range from the Extensive Air Showers (EAS) that these particles trigger in the atmosphere . By using the ISS altitude to monitor a target volume far greater than is possible from the ground, unprecedented statistical accuracy of the primary energy, arrival direction and composition of UHECRs will be obtained. Such data will shed light on the origin of the UHECRs, on the sources that are producing them, on the propagation environment from the source to the Earth and, possibly, on the particle physics mechanisms at energies well beyond those achievable in man-made accelerators. Moreover, there are exploratory objectives such as constraining the galactic and extragalactic magnetic fields, the detection of extreme energy neutrinos and gamma rays, the verification of special relativity at extremely large Lorentz factors, the examination of possible quantum gravity effects at extreme energies and the systematic surveillance of atmospheric phenomena. The Mini-EUSO instrument will have 2, 304 pixels from 36 multi-anode PMTs with each pixel viewing an equivalent area of 5.4 × 5.4 km2 on ground. The full field of view is ±19° and the instrument has a time resolution of 2.5 μs. The Mini-EUSO mission has at least four different objectives: (1) to raise the technical readiness level of JEM-EUSO to the highest grade, (2) to perform an absolute calibration of the multi-anode photomultipliers in flight (crucial for JEM-EUSO), (3) to take advantage of being at ISS altitude, like JEM-EUSO, and study in a precise way the UV background coming from Earth in all the different reflective conditions (water, earth, vegetation, snow, etc.) and (4) to study atmospheric phenomena, such as lightning, and related light, as well as meteors.
