Mini-EUSO

Mini-EUSO (Multiwavelength Imaging New Instrument for the Extreme Universe Space Observatory) is a UV telescope observing the Earth from the International Space Station, through a nadir-facing UV-transparent window in the Russian Zvezda module, since 2019.

The instrument employs a Fresnel-lens optical system and a focal surface composed of 36 Multi-Anode Photomultiplier tubes, 64 channels each, for a total of 2304 channels with single photon counting sensitivity. Mini-EUSO also contains two ancillary cameras to complement measurements in the near infrared and visible ranges. The detector saves triggered transient phenomena with a sampling rate of 2.5 μs (its maximum time resolution) and 320 μs, as well as continuous acquisition at 40.96 ms scale.

The scientific objectives of the mission range from the search for Extensive Air Showers (EAS) generated by Ultra-High Energy Cosmic Rays (UHECRs) with energies above 10²¹ eV, the search for nuclearites and Strange Quark Matter (SQM), up to the study of atmospheric phenomena such as Transient Luminous Events (TLEs), meteors and meteoroids.
Moreover Mini-EUSO can map the night-time Earth emissions in the near UV range (predominantly between 290-430 nm) with a spatial resolution of about 6.3 km (full field of view equal to 44°) and a maximum temporal resolution of 2.5 μs.
