KazSat-1


KazSat-1 is the first Kazakh communications satellite. It was launched on 17 June 2006, at 22:44:05 UTC by Proton-K / Blok DM-2M launch vehicle. This satellite was constructed by Khrunichev State Research and Production Space Center for the satellite bus and Thales Alenia Space for the payload. Thales Alenia Space is also the provider of KazSat-2 and KazSat-3 payloads.

Satellite description

The contract for the manufacture and launch of the first Kazakhstani geostationary spacecraft was signed in January 2004. Twelwe Ku-band transponders, KazSat-1 was a communications satellite planned to occupy a geosynchronous orbit approximately above the Earth. It was produced by Khrunichev State Research and Production Space Center in cooperation with Thales Alenia Space. The cost of Kazakhstan for the production of the first satellite amounted to US$65 million.
The spacecraft was delivered to the Baikonur Cosmodrome on 28 April 2006. The launch took place on 18 June 2006 at 4:44 a.m. using a Proton-K launch vehicle. For the first time in the history of the Proton rocket, in addition to Russian symbols, the flag of Kazakhstan and the insignia of the Republican Center for Space Communications were displayed. The launch of the first Kazakh satellite was observed at the cosmodrome by the President of Kazakhstan, Nursultan Nazarbayev, and the President of Russia, Vladimir Putin.

Mission

Partial control of the satellite was lost in July 2008 and completely in October 2008. It was supposed to serve for 10 years, but already on 26 November 2008, due to a failure in the on-board digital system, it stopped responding to control signals. The failure was declared irreversible, and in August 2009, the satellite was transferred to a burial orbit.
