The Mini-EUSO telescope is designed to perform observations of the UV light emission from Earth. It will be located in front of the UV transparent window in the Zvezda Russian module in the ISS, looking at Earth in nadir position.

The Mini-EUSO instrument comprises a compact telescope with a large field of view, ±19°, based on an optical system employing two Fresnel lenses (25 cm of diameter) for increasing light collection. The UV light is focused onto a Photo-Detector-Module (PDM) similar to EUSO-Balloon and EUSO-TA ones.

The main Mini-EUSO objectives are the study of atmospheric phenomena, like Transient Luminous Events (TLEs), meteors and meteoroides, the search for Strange Quark Matter (SQM) and the detection of some cosmic ray showers. Furthermore, Mini-EUSO could represent the first step in a roadmap of potential debris removal via laser ablation.

Mini-EUSO has been approved by the Russian Space Agency Roscosmos and included, with the name UV Atmosphere, into Russian “Stage program of scientific and applied research and experiments”. It has also been approved and funded by the Italian Space Agency (ASI). Technical requirements for installation inside the ISS have been studied by RSC “Energia”. The instrument is in final phase of realization. The installation on board the ISS is foreseen for the second half of 2018.
