The launch was contracted by Khrunichev State Research and Production Space Center, and used a Proton-K / Blok DM-2M launch vehicle flying from Site 200/39 at the Baikonur Cosmodrome.
Launch
Ekspress-A4 is a Russian geosynchronous communications spacecraft that was launched on 10 June 2002 from Baikonur by a Proton-K launch vehicle at 01:14:00 UTC. The 2,600 kg (5,700 lb) spacecraft carries 12 transponders in C-band and five in Ku-band to provide voice, data, and video communications in Russia.
Mission
It is part of the Ekspress network of satellites. Following its launch and on-orbit testing, it was placed in geostationary orbit at 40° West, from where it provides communications services to Russia. It is equipped with seventeen transponders. In January 2020, the satellite was retired and moved to a graveyard orbit above the geostationary orbit.
