The Kosmos-3M (Russian: Космос-3М meaning "Cosmos", GRAU index 11K65M) is a Russian space launch vehicle. It is a liquid-fueled two-stage rocket, first launched in 1967 and with over 410 successful launches to its name. The Cosmos 3M uses nitrogen tetroxide as an oxidizer to lift roughly 1400 kg of payload into orbit. It differed from the earlier Cosmos 3 in its finer control of the second-stage burn, allowing operators to tune the thrust and eve...

The Kosmos-3M (Russian: Космос-3М meaning "Cosmos", GRAU index 11K65M) is a Russian space launch vehicle. It is a liquid-fueled two-stage rocket, first launched in 1967 and with over 410 successful launches to its name. The Cosmos 3M uses nitrogen tetroxide as an oxidizer to lift roughly 1400 kg of payload into orbit. It differed from the earlier Cosmos 3 in its finer control of the second-stage burn, allowing operators to tune the thrust and even channel it through nozzles that helped orient the rocket for the launching of multiple satellites at one time. PO Polyot has manufactured these launch vehicles in the Russian town of Omsk for decades, though the latest digitally controlled rockets are now officially referred to as "Cosmos 3MU." It is scheduled to be retired from service in 2011.
On June 26, 1973 , the explosion of a Cosmos 3M at Plesetsk Cosmodrome killed 9 people. In 1976, the explosion of a Cosmos 3M on its launchpad killed nine engineers. More recently, on November 21,...
