Well the end of year is fast approaching! But just before we celebrate the coming of 2014, here's one last Proton launch in just an hour from now. And maybe it's time to get scared too, as the payload is Express-AM5, the latest member of communication satellites owned by the state-owned Russian Satellite Communications Company. Would the Russian-built 3.4 tonne satellite, based on a new designed satellite platform, make it to the planned orbit? We shall see, we shall see....

Express-AM5 communication satellite:
Mission Summary
The Ekspress-AM 5 is a communications satellites for russian domestic communication services. The lifetime of the spacecraft has been increased to 15 years. While the spacecraft itself is built by russian RSCC (Kosmicheskiya Svyaz), the communication payloads are built by MacDonald, Dettwiler and Associates Ltd. (MDA). It consists of 30 C-band, 40 Ku-band, 12 Ka-band and 2 L-band transponders.
On Aug. 12, 2009, ISS Reshetnev reached an agreement with Russian Satellite Communications Company, RSCC, to develop a pair of new-generation communications satellites, Ekspress-AM5 and Ekspress-AM-6. The 3,400-kilogram Ekspress-AM5 would be the first spacecraft based on ISS Reshetnev's Ekspress-2000 platform, the company's largest standard bus. According to ISS Reshetnev, Ekspress-2000 could accommodate 10 antennas and 84 transponders. The 1,070-kilogram communications payload onboard Ekspress-AM5 included C-band, Ku-band, L-band transponders and, for the first time in the Russian practice, Ka-band transponders. The Canadian company, MDA, won a contract to build transponders and antennas for the spacecraft.
The satellite will provide a broad range of digital communications and broadcast services, including government communications.
The onboard power supply system featuring for the first time five-section solar panels with a total area of 84 square meters and a span of more than 33 meters, was designed to provide at least 12.1 kilowatts of electricity to the payload and a total power output of 15 kilowatts.
Ekspress-AM5 and AM6 were also equipped with four electric engines, SPD-100V, using 300 kilograms of xenon gas as a propellant to insert these satellites into their final orbits three or four months after launch. The new propulsion system helped to resolve the payload limitations of the Proton rocket providing a total of 150 kilograms in mass savings.
The spacecraft was to be positioned at 140 degrees East longitude over the Equator and have a life span of 15 years. The satellite was ensured for 7.08 billion rubles.
The satellite is 7.723 millimeters tall.

Proton-M Ascent Profile
The Proton-M first three stages place the orbital unit (OU), which consists of a Breeze-M upper stage, adapter system and the two satellites, into a 51.5° inclination suborbital trajectory.
Proton-M powered flight lasts 582 seconds. The OU powered flight begins at the moment of the third stage separation.
Immediately after the separation of the third stage booster, the Breeze-M stability engines start, damping the angular velocities of the third stage separation and then providing orbital unit orientation and stability during coast flight along a suborbital trajectory to await the first burn. The upper stage follows a five-burn injection profile.
