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 by the Soyuz 2.1a launch vehicle.
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 have not been solved and all the scientific equipment of the satellite are powered off. The recovery attempts continue (some systems of the satellite are responsive, the problem is with scientific payload systems). Before succumbing to current difficulties, the satellite had worked for one and a half year 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 in July 2019.
The TUS-telescope aboard Lomonosov stopped data collection in late 2017.
