Practical importance
• For the first time a mirror-concentrator 2 m2 in area with a matrix of UV-detectors in its focus is launched to the orbit. This «camera» provides an opportunity for separation and observation of the evolution of UV-bursts with by a factor of 104 lower brightness than it's carried currently by means of video-cameras (with up 2 cm2 inlet area).
• Observation of the bursts by means of state-of-the-art video-cameras has discovered specific type of electric discharges originated between the clouds and the ionosphere which concentrate huge energy (up to hundreds of Gigajoules). This energy is released as electromagnetic radiation at different frequencies from radio up to gamma. Presence of gamma-radiation with energy of about 1-10 MeV proves that in such discharges electrons are accelerated up to the same energy, which is unusual for «ordinary» gas discharge. At the altitude of 10-20 km powerful flux of high-energy electrons produce great radiation danger and therefore studies of the «new» type discharges' nature are necessary for understanding of the real danger of flights under the conditions of the increased probability of the discharges between the clouds and the ionosphere.
Space Project«Lomonosov»
• There is also another reason for interest to the phenomenon of powerful discharges between the clouds and the ionosphere. By its brightness and radiation composition (including high-energy electrons) such discharges have much in common with atmospheric effects of atomic explosion. At the moment there is no fully reasonable theory of new type discharges. For its development it is necessary to study discharge processes not only at its maximum phase, but also at its initial phase when intensity of all types of radiation is still weak. Scientific equipment of «Lomonosov» project will provide information about the primary phase of the discharge due to very high light ratio of the facility.
• Research progress will considerably depend on the equipment complex efficient for observations of both initial and the most energetic (bright) phases of the discharge. It is provided to mount additional devices for the studies of the bright phase of the discharge.
Space Project«Lomonosov»
• It's also important to accompany orbital observations with measurements of radio-signals from the discharge by means of International network of ground stations, which determine discharge's location by triangulation method and measure radio-impulse shape.
• Launch of the satellite «Lomonosov» surely will contribute greatly to the development of human knowledge in one of the most important fields of physics whose studies were started by M.V. Lomonosov (studies of lightnings nature).
