Two more satellites in the Luch-5A range are scheduled to be launched \u2013 Luch-5B in 2012 and and Luch-4 in 2013.<\/p>\n
Israel\u2019s AMOS-5 satellite is aimed at Africa\u2019s emerging satellite services market, taking position at the new 17 Degrees East location. Once in orbit, the AMOS-5 satellite will feature a fixed pan-African C-band beam and three steerable Ku-band beams \u2013 all covering Africa with connectivity to Europe and the Middle East and supporting multiple transponders in both C-band and Ku-band.<\/p>\n
Together with the AMOS-2 and the AMOS-3 satellites co-located at Spacecom\u2019s 4 Degrees W orbital \u201chot spot,\u201d the AMOS-5 satellite will give the company\u2019s customers coverage over many of the world\u2019s fastest growing and highest-demand satellite markets in the Middle East, Central and Eastern Europe, Central Asia and Africa.<\/p>\n
With an expected lifetime of 15 years, AMOS-5 sports 18 Ku-band and 18 C-band transponders, providing a variety of coverage, including Direct-To-Home TV broadcasting services.<\/p>\n

The Proton booster tasked with the launch of the satellite duo was 4.1 m (13.5 ft) in diameter along its second and third stages, with a first stage diameter of 7.4 m (24.3 ft). Overall height of the three stages of the Proton booster is 42.3 m (138.8 ft).<\/p>\nThe first stage consists of a central tank containing the oxidizer surrounded by six outboard fuel tanks. Each fuel tank also carries one of the six RD-276 engines that provide first stage power. Total first stage vacuum-rated level thrust is 11.0 MN (2,500,000 lbf).<\/p>\n
Of conventional cylindrical design, the second stage is powered by three RD-0210 engines plus one RD-0211 engine and develops a vacuum thrust of 2.4 MN (540,000 lbf).<\/p>\n
Powered by one RD-0213 engine, the third stage develops thrust of 583 kN (131,000 lbf), and a four-nozzle vernier engine that produces thrust of 31 kN (7,000 lbf). Guidance, navigation, and control of the Proton M during operation of the first three stages is carried out by a triple redundant closed-loop digital avionics system mounted in the Proton\u2019s third stage.<\/p>\n
The Breeze-M upper stage is the Phase III variant, a recent upgrade which utilizes two new high-pressure tanks (80 liters) to replace six smaller tanks, along with the relocation of command instruments towards the centre \u2013 in order to mitigate shock loads when the additional propellant tank is being jettisoned.<\/p>\n
It was a problem with that upper stage which resulted in the loss of the Ekspress-AM4 communications satellite in August, when the stage, otherwise known as the Briz-M, failed to insert the satellite into the correct transfer orbit due to a problem with the last of the mission profile burns.<\/p>\n
This failure led to a delay for the ViaSat-1 mission, which was initially scheduled for September, prior to its successful launch \u2013 conducted by International Launch Services \u2013 on October 19.<\/p>\n

A Russian government Proton-M launch vehicle has successfully launched with two satellites \u2013 Russia\u2019s Luch-5A and Israel\u2019s AMOS-5 \u2013 on Sunday. Launch was nominal and on schedule at 11:17 GMT from the Baikonur Cosmodrome in Kazakhstan, ahead of a long flight profile which involved four burns of the Briz-M (Breeze-M) Upper Stage.
