The Tsyklon-3, also known as Tsiklon-3, GRAU index 11K68, was a Soviet, and subsequently Ukrainian orbital carrier rocket. A derivative of the R-36 ICBM, and a member of the Tsyklon family, it made its maiden flight on 24 June 1977, and was retired on 30 January 2009.[1] The Ukrainian-built Tsyklon rockets were retired in favour of future all-Russian carrier rockets, such as the Angara, and because they were fuelled by toxic hypergolic propellants.[2]

Successor[edit]

Ukraine is developing a commercial derivative of the Tsyklon-3, the Tsyklon-4.[citation needed]

2013 loss of Ecuadorian satellite after impact with Tsyklon-3 space debris[edit]

On 23 May 2013 at approximately 05:38 UTC, the Ecuadorian satellite NEE-01 Pegaso passed very close to the spent upper stage of a 1985 Tsyklon-3 rocket over the Indian Ocean. While there was no direct collision between the satellite and upper stage, Pegaso is believed to have suffered a "glancing blow" after passing through a debris cloud around the Tsyklon stage and striking one of the small pieces.[3][4] After the incident, the satellite was found to be "spinning wildly over two of its axes" and unable to communicate with its ground station.[3] Efforts to reestablish control of Pegaso failed,[4] and on 28 August 2013 the decision was made by EXA and the Ecuadorian government to declare the satellite as lost.[5]
