    Arabsat and SES launch success

    Arabsat and SES launch success
    By Chris Forrester



    After a 48-hour delay caused by local technicians going on strike, the Arianespace mission to launch Arabsat 5C and SES-2 was successfully carried out late on the night of September 21/22.

    The flight was the 5th launch this year for the giant Ariane 5 rocket, and its two passengers were successfully placed into a geostationary transfer orbit following lift-off at 11.38pm (Paris time).

    Arabsat 5C was built by Astrium and Thales Alenia Space for the satcom operator Arabsat, based in Riyadh, Saudi Arabia. Astrium supplied the Eurostar E3000 platform and handled satellite integration, while Thales Alenia Space supplied the payload. Fitted with 26 C-band transponders and 10 Ka-band spotbeams, Arabsat 5C will deliver telecommunications services, as well as broadcasting TV programming to the Middle East and North Africa. Positioned at 20 degrees east, it offers a design life exceeding 15 years.

    SES-2 was built by Orbital Sciences Corporation using a Star 2.4 platform. It is fitted with 24 C-band and 24 Ku-band transponders, and offers a design life of 15 years. Positioned at 87 degrees west, SES-2 will broadcast programming for the world’s leading TV stations through one of the largest distribution networks in the market. It will also provide VSAT services for professional customers and government agencies in North America and the Caribbean.

    Arabsat-5C and SES-2 are orbited

    06.46 Europe/London, September 22, 2011 By Robert Briel

    Telecommunications satellites for two key Arianespace customers were launched last night on the company’s fifth Ariane 5 flight of 2011.
    Delivering a total payload lift performance of approximately 8,975 kg., the mission lofted Arabsat-5C for the Arab Satellite Communications Organization (Arabsat) and SES-2, which will be utilised by Europe’s SES.
    Arabsat-5C was deployed first, separating from Ariane 5 at 27 minutes after liftoff, followed eight minutes later by SES-2.
    “Arabsat decided several years ago to entrust us with the launch of all its satellites, and the successful orbiting of this eighth satellite demonstrates that my friend, Khalid Balkheyour, Arabsat’s president and CEO, was right to place his confidence in us,” said Arianespace Chairman & CEO Jean-Yves Le Gall. “Because of his wise choice, Arabsat has become one of the world’s leading operators – and I congratulate it for this superb success.”
    Once positioned at Arabsat’s 20 degrees East orbital location, Arabsat-5C will deliver capacity in both the C- and Ka-bands for a range of communications services. The spacecraft was manufactured in a joint effort by Europe’s EADS Astrium and Thales Alenia Space.
    The SES-2 passenger for the mission was the 35th SES satellite launched by an Ariane vehicle, and is equipped with 24 C-band and 24 Ku-band transponders. It will replace SES’ AMC-3 spacecraft at 87 degrees West, providing coverage for North America and the Caribbean. Also integrated aboard SES-2 is the Commercially Hosted Infrared Payload (CHIRP) sensor for the U.S. Air Force – which integrates a wide-field of view sensor for testing by the military service.
    “We are particularly proud of the loyalty that SES has demonstrated since more than 20 years, and I wish to particularly thank Tip Osterthaler, the president and CEO of SES WORLD SKIES U.S. Government Solutions,” Le Gall said. “I also want to thank our friends at the U.S. Air Force, because together, we have opened a new chapter for the space industry tonight in launching CHIRP on SES-2 as the initial military payload on a civilian satellite. Arianespace is honoured to once again be part of a world’s first!”
    The next Ariane 5 flight is planned for early 2012, performing its third mission to loft a European Automated Transfer Vehicle (ATV) for servicing of the International Space Station.
