KazSat-1 ({{langx|kk|ҚазСат-1}}, QazSat-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.{{cite web|url=http://planet4589.org/space/log/launchlog.txt|title=Launch Log|publisher=Jonathan's Space Report|date=14 March 2021|access-date=28 April 2021}}{{cite web|url=https://news.bbc.co.uk/1/hi/world/asia-pacific/5092460.stm|title=First Kazakh satellite into orbit|publisher=BBC News|date=18 June 2006|access-date=28 April 2021}} This satellite was constructed by Khrunichev State Research and Production Space Center for the satellite bus and Thales Alenia Space (Italy) 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.{{cite web|url=https://www.newsru.com/world/18jun2006/orb.html |title=The first Kazakh satellite was launched into a predetermined orbit|publisher=Newsru.com|date=18 June 2006|access-date=28 April 2021}} Twelwe Ku-band transponders (each 72 MHz), KazSat-1 was a communications satellite planned to occupy a geosynchronous orbit approximately {{cvt|36000|km}} above the Earth. It was produced by Khrunichev State Research and Production Space Center in cooperation with Thales Alenia Space (Italy). The cost of Kazakhstan for the production of the first satellite amounted to US$65 million.
Mission
Partial control of the satellite was lost in July 2008 and completely in October 2008.{{cite web|url=http://www.satellitetoday.com/via/multimedia/23879.html|title=Kazakhstan Keeps Quiet about Kazsat-1 Loss|last=Brown|first=Peter J.|publisher=Via Satellite|access-date=29 April 2013|archive-date=27 October 2009|archive-url=https://web.archive.org/web/20091027131959/http://www.satellitetoday.com/via/multimedia/23879.html|url-status=dead}} 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.{{cite web |url=https://www.newsru.com/world/19Apr2011/kazsat2.html|title=Kazakhstan is pulling Russia into a new "space scandal" - it again wants to "push" an unreliable satellite to it|publisher=Newsru.com|date=19 April 2011|access-date=28 April 2021}}
