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 420 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. It was originally scheduled to be retired from service in 2011,[1] however in April 2010 the Commander of the Russian Space Forces confirmed that it would be retired by the end of 2010.[2] One rocket remains to be launched.

Accidents

On June 26, 1973, the explosion of a Kosmos 3M at Plesetsk Cosmodrome killed 9 people.[5] In 1976, the explosion of a Kosmos 3M on its launchpad killed nine engineers.[citation needed] More recently, on November 21, 2000, a Kosmos 3M launcher failed to place the QuickBird 1 satellite into orbit due to a failure of its second stage. The rocket and satellite reentered the atmosphere over Uruguay, and an inquest into the accident was inconclusive.
