Ariane 5 Lofts Dual Birds

by Staff Writers
Kourou, French Guiana (SPX) Oct 29, 2010
The fourth Ariane 5 mission of 2010 successfully delivered two telecommunications satellites to geostationary transfer orbit today, marking the 53rd flight for Arianespace's heavy-lift workhorse and its 39th consecutive success.

Lifting off on time at 6:51 p.m. from the Spaceport's ELA-3 launch zone in French Guiana, the Ariane 5 deployed its W3B and BSAT-3b passengers during a flight lasting just under 38 minutes. The launcher's payload lift performance was approximately 8,260 kg., which included a combined 7,460 kg. mass for the two satellites, along with Ariane 5's SYLDA 5 multi-payload dispenser system and associated integration hardware.

"With this evening's success, we already have launched eight large telecommunications satellites since the beginning of 2010, which is more than all of our competitors combined," said Arianespace Chairman and CEO Jean-Yves Le Gall. "This follows our Soyuz mission last week, performed from Baikonur by our friends at Starsem, which orbited six constellation satellites - all of which shows the relevance, efficiency and availability of our launcher family."

Ariane 5 delivered another highly accurate performance in tonight's mission, with the following provisional orbital parameters at the injection of its cryogenic upper stage:

- Perigee: 249.2 km. for a target of 249.3 km.

- Apogee: 35,907 km. for a target of 35,911 km.

- Inclination: 2.00 deg. for a target of 2.00 deg.

The 5,370-kg. W3B satellite for Eutelsat was deployed on tonight's Ariane 5 flight was deployed at 28 minutes into the mission, marking a new step in Arianespace's uninterrupted relationship with Europe's leading satellite operator, which has spanned more than 25 years.

W3B is the 25th Eutelsat satellite orbited by Arianespace, and it will offer significant flexibility for a wide range of services from TV broadcasting to professional data networks and broadband access.

Based on Thales Alenia Space's 4000 spacecraft platform, W3B will have a coverage area over Europe, the Middle East, Central Asia, Africa and the Indian Ocean Islands, with an operational design lifetime of 15 years. It initially will be located at 16 deg. East, followed by a move to an orbital slot of 7 deg. East for collocation with Eutelsat's W3A satellite.

The BSAT-3b satellite launched by Arianespace today was lofted for Lockheed Martin Commercial Space Systems on behalf of Japan's B-SAT Corporation. This was the seventh B-SAT spacecraft orbited by Arianespace. Manufactured using Lockheed Martin's A2100 A platform, the 2,060-kg. relay satellite is fitted with 12 130-watt Ku-band channels - with eight operating at a time. B-SAT will deliver direct-to-home television programming to Japan during its planned 15-year-plus lifetime.

"Japan is one of the major partners of our company," explained Le Gall. "Out of a total of 36 Japanese satellites open to competition for launch services, we have signed 27 of the contracts. And for the past several years, we have won 100 percent of the market - which really is quite significant."

The next Ariane 5 mission is set for November 25 with another heavy-lift launch, carrying the Intelsat 17 and HYLAS 1 satellites. It will be followed by one additional mission of this workhorse vehicle before the end of 2010.

Ariane 5 Rolls Out For Dual Bird Launch
Kourou, French Guiana (SPX) Oct 29, 2010
The Ariane 5 for Arianespace's next mission has moved to the launch pad at Europe's Spaceport, readying it for tomorrow's liftoff with a dual payload of telecommunications satellites for Europe and Japan. Emerging under clear French Guiana skies at 10:45 a.m. local time, the heavy-lift Ariane 5 ECA was transferred during a one-hour process from the Spaceport's Final Assembly Building to th ... read more
