Ekspress
Ekspress (russian: Экспресс meaning Express), is a series of geostationary communications satellites owned by Russian Satellite Communications Company (RSCC). The first satellite of this kind was launched on 13 October 1994. The satellites are produced by the company Information Satellite Systems Reshetnev (ISS Reshetnev). Overview The Ekspress series of communication satellites (industry code 11F639) was developed by the satellite company NPO PM as a replacement for the old Gorizont series of comsats. The first satellite of the series, Ekspress 1, was launched in 1994. It had a mass of 2500 kg, 17 channels and an operational lifetime of at 5–7 years. Starting in the mid-1990s, NPO PM started to make significant effort to close the technology gap between Russian and Western communication satellites. Cooperation with the French company Alcatel (now Thales Alenia Space) was begun in 1995. The first satellite of a new second series, Ekspress A-1, had 12 Alcatel-bui ...

Briz (rocket Stage)
The Briz-K, Briz-KM and Briz-M (russian: Бриз-К, КM and M meaning ''Breeze-K, KM and M'') are Russian liquid-propellant rocket orbit insertion upper stages manufactured by Khrunichev State Research and Production Space Center and used on the Proton-M and Angara A5. The upper stages were also used on Rokot, one of Russia's smaller launchers, before its retirement in 2019. Characteristics Briz-K and Briz-KM Briz-K, GRAU index 14S12, is a single-piece structure with a conical tank compartment and the engine located in a recess in the fuel tank. Briz-KM (GRAU index 14S45) is an improved version of Briz-K. The Briz-K and Briz-KM were used as a third stage of the Rokot launch vehicles. Briz-M Briz-M, GRAU index 14S43, is designed for injecting large payloads into a low, medium-height or high geosynchronous orbit. Briz-M is a twin upper stage consisting of a core module (using Briz-KM as the baseline) and a jettisonable add-on toroidal tank surrounding the core. It is po ...

Ekspress AM4
Ekspress-AM4 was a Russian communications satellite placed into the wrong orbit from a faulty Briz-M rocket stage. This satellite was to be part of the Ekspress series of geostationary communications satellites owned by Russian Satellite Communications Company (RSCC). Proposals were made to reposition the satellite to provide broadband services to Antarctica, but ultimately the decision was made to de-orbit the satellite. On 28 March 2012, the satellite splashed into the Pacific Ocean. Satellite description The total mass of the Ekspress-AM4 satellite was , and the satellite had 63 transponders. The onboard antennas were capable of broadcasting in the C-band, Ku-band, L-band, and Ka-band. The satellite's orbit was measured at 695 by 20239 km altitude, with an inclination orbit of 51.1°. Though the satellite was placed in the wrong orbit, there was no damage to the satellite, meaning that it became the subject of numerous reuse proposals. Launch The Ekspress-AM4 sa ...

Ekspress-MD2 is a Russian communications satellite which was lost due to a launch failure on 6 August 2012. Equipped with eight C-band transponders and 1 L-band transponder, it was intended to be located in geostationary orbit at a longitude of 145° East. It was the second Ekspress-MD satellite to be launched, following Ekspress-MD1 in 2009. Launch Ekspress-MD2 was launched atop a Proton-M launch vehicle with a Briz-M upper stage on 6 August 2012 at 19:31:00 UTC. The Indonesian Telkom-3 satellite was also carried aboard the launch vehicle. Launch occurred from Site 81/24 at the Baikonur Cosmodrome in Kazakhstan. The first three stages of the Proton launched worked as expected and the satellites were attached to the Briz-M upper stage which would transfer them into geosynchronous orbit. The Briz-M undertakes a series of four burns with coasting stages in order to do this. The third burn was due to be 18 minutes long but the engines cut out after 7 seconds, leaving the sa ...
