Description

The satellite "Lomonosov" was launched on April, 26 2016. The main objective of the experiments on board this satellite– to study of extreme physical phenomena in space. Among them are Cosmic Ray of Ultra - High Energy (UHECR) and cosmic transient gamma-ray bursts. For UHECR measurements on board this satellite the mirror-type ultraviolet telescope (TUS) was installed for measurements of Extensive Air Showers (EAS) in the atmosphere initiated by UHECR. It is the world's first space experiment which can allow to register particles in the energy region of the Greisen –Zatsepin - Kuzmin (GZK) - more than 5 × 10 19 eV. Results of the first measurements of transient UV flashes in the atmosphere of a different nature are presented. The possibility of identifying candidates for EAS from UHECR have been estimated. Cosmic gamma –ray bursts on board "Lomonosov" were recorded with the help of multiwave instruments in UV, optical - visible and gamma ranges by gamma-ray spectrometer (BDRG), ultraviolet image telescope (SMT) with a gamma detector (UBAT) - UFFO and wide-field optical camera SHOK. The results of the analysis of observations of Gamma-ray Bursts and Soft Gamma - ray Repeaters – their timing and power characteristics are presented.
