| Outline of Annual Research Achievements |
The engineering and the flight models of Mini-EUSO have been completed. All the phases of integration, calibration and pre-flight qualification tests were completed first in Japan, subsequently in Italy and Russia and finally at the cosmodrome of Baikonur. The detector has been launched toward the ISS on Aug. 22, with an uncrewed Soyuz MS-14 capsule. It was turned on on Oct. 7th and is currently undergoing periodic data acquisition in the Russian section of the ISS. The commissioning was successfully completed, with analysis of a selection of data directly downlinked to ground via telemetry. Analysis of the data obtained from the station so far show the correct functioning of the telescope.We confirmed UV map of the night-time Earth was being successfully accumulated. Among the phenomena observed we have the observation of the UV emissions from the Earth in different conditions of moonlight. Night UV maps have been prepared. Other observed phenomena include meteors of varying size and velocity, Transient Luminous events such as ELVES, superluminal ring like structures that expand in the ionosphere after being triggered by and underlying Intra-cloud lightinings. Pouches containing the full data set are returned with a soyuz capsule to the ground. The pouches are rotated every six months. Work on the analysis of EUSO-SPB balloon flight has continued in parallel to the the preparation of the next balloon flight (EUSO-SPB2) currently scheduled from NZ in 2022. This involved mostly the electronics and detectors of the focal surface and the study of the various lens systems.
