Thales Alenia Space, constructed Ekspress-AM8 payload, and ISS Reshetnev constructed the satellite bus which was based on the Ekspress-1000NTB. The satellite has a mass of 2,100 kg (4,600 lb), provides 5.9 kilowatts to its payload, and a planned operational lifespan of 15 years. The satellite carried 62 transponders: 24 operating in the C-band of the electromagnetic spectrum, 12 in the Ku-band and 2 in the L-band.[1]
Ekspress-AM8 was originally to be launched in 2012 or 2013 into RSCC's 14° West longitude, but was delayed to 2015. It used a Proton-M / Blok DM-03launch vehicle to be inserted directly into geostationary orbit.[3]
Launches are separated by dots ( • ), payloads by commas ( , ), multiple names for the same satellite by slashes ( / ). Crewed flights are underlined. Launch failures are marked with the † sign. Payloads deployed from other spacecraft are (enclosed in parentheses).
