On March 30, 2012 at 05:49 UTC the "Proton-K” rocket-carrier equipped with the DM-2 booster was launched from Baykonur Cosmodrome.
The rocket orbited the Russian "Kosmos-2479” military satellite. Observers believe the payload was an Oko-class early warning satellite designed to detect missile launches with an infrared telescope.
It was the last launch of a Proton-K rocket. This was the 310th mission of the legendary launch vehicle over the 45 years of its flights. The first-ever launch of a Proton K took place on 10 March 1967 with the "Kosmos-146” satellite onboard. This launch was also the 375th one in the flight history of the Proton family.
The Proton launch vehicle was designed and put on a production line by the state-owned Khrunichev State Research and Production Space Center FGUP (a Federal State Unitary Enterprise).
