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 Kosmos-3M uses AK27P (red fuming nitric acid) or dinitrogen tetroxide as an oxidizer to lift roughly 1,400 kg (3,100 lb) of payload into orbit. It differed from the earlier Kosmos-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 further launch, with Kanopus-ST, was planned - however this was cancelled in late 2012 as the rocket had exceeded its design life while in storage ahead of the launch.

Launches

First launched in 1967, with over 420 successful launches to date (2009).

Accidents

On 26 June 1973, the explosion of a Kosmos-3M at Plesetsk Cosmodrome killed 9 people.[9] In 1976, the explosion of a Kosmos 3M on its launchpad killed nine engineers. More recently, on 21 November 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.
