OR:

Mikhailo Lomonosov (MVL-300, or Mikhailo, or more commonly Lomonosov; MVL stands for Mikhail Vasilyevich Lomonosov) is an astronomical satellite operated by
Moscow State University M. V. Lomonosov Moscow State University (MSU; russian: Московский государственный университет имени М. В. Ломоносова) is a public research university in Moscow, Russia and the most prestigious ...
(MSU) named after Mikhail Lomonosov.


Mission

The objective of the mission is the observation of
gamma-ray burst In gamma-ray astronomy, gamma-ray bursts (GRBs) are immensely energetic explosions that have been observed in distant galaxies. They are the most energetic and luminous electromagnetic events since the Big Bang. Bursts can last from ten millise ...

s and transient phenomena in the Earth's upper atmosphere.


Launch

The mission launch was initially planned for 2011 when 300 years since the birthday of Mikhail Lomonosov was celebrated. After several postponements the mission was finally launched on 28 April 2016 from
Vostochny Cosmodrome The Vostochny Cosmodrome (russian: Космодром Восточный, ''Kosmodrom Vostochny'', "Eastern Spaceport") is a Russian spaceport (still partly under construction) above the 51st parallel north in the Amur Oblast, in the Russian ...
by the Soyuz 2.1a launch vehicle.


Scientific payload

The spacecraft is equipped with seven scientific instruments: *Tracking Ultraviolet Set Up system (TUS) was designed to measure fluorescence light radiated by EAS (Extensive Air Showers) of Ultra High Energy Cosmic Rays (UHECR) in the Earth atmosphere as well as for transients' studies within UV-range. This was the first space based instrument dedicated to these phenomena. The TUS-project started in 2001. *Block for X-ray and gamma-radiation detection (BDRG) is intended for detecting and monitoring

and for producing a trigger signal for ShOK cameras (see below); * UFFO consists of X-ray and 10 cm UV telescopes intended for studying gamma-ray bursts; *Optic cameras of super-wide field of vision (ShOK) is a pair of wide-field optical cameras, which main purpose is a prompt detection of the optical radiation of gamma-ray bursts after receiving trigger signals from BDRG; *Dosimeter of Electrons, PROtons and Neutrons (DEPRON) measures absorbed doses and spectra of electrons, protons, neutrons and heavy nuclei; *Electron Loss and Fields Investigator for Lomonosov (ELFIN-L) comprises the Energetic Particle Detector for Electrons (EPDE), Energetic Proton Detector for Ions (EPDI) and Flux Gate Magnetometer (FGM). Its main purposes is to study energetic particles in the Earth magnetosphere; *IMISS-1 is a device intended to test microelectromechanical inertial modules.


End of mission

The TUS-telescope aboard Lomonosov stopped data collection in late 2017. On June 30, 2018, it was published that the Lomonosov-satellite had suffered a malfunction in its data transmission system. Attempts to fix the problem were underway, but fixing the problem had so far been unsuccessful. As of 14 January 2019, the problems had not been solved and all the scientific equipment of the satellite were powered off. The recovery attempts continued (some systems of the satellite were responsive, the problem was with scientific payload systems). Before succumbing to these difficulties, the satellite had worked for one and a half years for its intended purpose. With the failure of the Lomonosov satellite and the Spektr-R end of mission on 30 May 2019, the Russian space program lost both of its scientific satellites until the launch of
Spektr-RG Spektr-RG ( Russian: Спектр-РГ, ''Spectrum'' + '' Röntgen'' + ''Gamma''; also called Spectrum-X-Gamma, SRG, SXG) is a Russian–German high-energy astrophysics space observatory which was launched on 13 July 2019. It follows on from th ...
in July 2019.
