Arianespace’s double success: 50th Ariane 5 mission, 36th successful launch in a row - ASTRA 3B and COMSATBw-2 in orbit
Kourou, May 21, 2010
On Friday, May 21, Arianespace placed two communications satellites into geostationary transfer orbit: the ASTRA 3B commercial communications satellite for the Luxembourg-based operator SES ASTRA, and the COMSATBw-2 military communications satellite built by Astrium for the German Ministry of Defense.
50th Ariane 5 launch, 36th success in a row
The latest successful launch of an Ariane 5, the first in 2010, confirms that Arianespace’s launch Service & Solutions continue to set the global standard for all telecommunications operators, whether civil or military. It also reflects the strategic facet of Arianespace, which guarantees independent access to space for all European governments.
Ariane 5 is the only commercial satellite launcher now on the market capable of simultaneously launching two payloads, giving Arianespace customers outstanding performance, flexibility and competitiveness.
This was the 50th launch of an Ariane 5 and the 36th successful launch in a row.
Supporting civil and military satcom solutions
Over the last two decades, Arianespace and SES have developed an exceptional relationship. ASTRA 3B, built by Astrium, is the 33rd satellite from the SES group (Euronext Paris and Luxembourg Bourse: SESG) to have chosen the European launcher. SES ASTRA operates the leading direct-to-home (DTH) TV broadcast system in Europe, serving more than 125 million households via DTH and cable networks.
COMSATBw-2 is the 34th military payload to use the European launcher. Astrium chose Arianespace for the launch of two military communications satellites, COMSATBw-1, orbited in October 2009, and COMSATBw-2, as part of a satellite communications system set up by the German Ministry of Defense.
ASTRA 3B/COMSATBw-2 mission at a glance
The mission was carried out by an Ariane 5 ECA launcher from Europe's Spaceport in Kourou, French Guiana. Liftoff was on Friday, May 21, 2010 at 7:01 pm local time in Kourou (6:01 pm in Washington, D.C., 22:01 UT, 12:01 am in Paris on Saturday, May 22, and at 2:01 am in Moscow).
ASTRA 3B was built by Astrium using a Eurostar 3000M platform, and weighed 5,500 kg at launch. Fitted with 60 active Ku-band transponders and four Ka-band transponders, ASTRA 3B will be positioned at 23.5 degrees East. It will deliver high-power broadcast services across all of Europe, and offers a design life of about 15 years.
COMSATBw-2 weighed 2,500 kg at launch and offers a design life of 15 years. Its coverage zone extends from the Americas to the Far East, and it will be operated from different sites by German aerospace agency DLR. German armed forces will take advantage of a secure network for voice, data, fax, video and multimedia transmissions. Astrium is in charge of the space segment, including in-orbit delivery of the satellite. Thales Alenia Space designed, manufactured, integrated and tested the satellite, which it delivered before launch to Astrium. Most of the payload for the satellite was produced by Tesat, Astrium’s German subsidiary. Through the joint venture Milsat Services, Astrium is also responsible for the satellite communications contract.
