Ariane 5 Said To Boost Record Heavy Payload: U.K., Brazilian Satellites
The Ariane 5 giant rocket set another heavy-lift record by placing a U.K. military relay platform and Brazil’s new multi-mission telecommunications satellite into geostationary transfer orbit, according to Arianspace.
The total payload delivery weight was 9,535 kg (10.5 tons), which included 8,735 kg (9.6 tons) for the two satellites, along with the associated installation/interface hardware and Ariane’s SYLDA 5 dual payload dispenser system.
The Ariane 5 lifted off from the European spaceport in French Guiana, South America, and climbed through a deck of broken low clouds over the spaceport.
Tracking cameras followed the trajectory as the launcher came back into view, clearly showing the jettisoning of Ariane 5’s two solid rocket boosters.
Skynet 5B was deployed by the launcher approximately 27 minutes into the mission, and Star One C1 was released about six minutes later.
This was the fifth Ariane 5 dual-satellite launch in 2007, clearing the way for a record sixth flight in December, according to Arianespace.
"Since the beginning of 2007, 12 large commercial communications satellites have been launched [worldwide], and we launched 10 of them — 83 percent of the total, which also is a record," Jean-Yves Le Gall, Arianespace chairman & CEO, said.
The mission came just eight months after Ariane 5 lofted Skynet 5A for the British Ministry of Defence, and Le Gall noted as well that Star One C1 continues a more than 20-year relationship with Brazil, pointing out that all seven satellites in the Star One fleet have orbited by Arianespace.
Skynet 5B was the 28th national security satellite lofted by Arianespace, and the sixth platform in the Skynet series orbited aboard Ariane. This 4,635-kg (5.1 tons) spacecraft was built by Astrium, and will be delivered in orbit to Paradigm Secure Communications. When operational, it will handle secure communications services for the United Kingdom’s armed forces, NATO and other countries. Arianespace’s order backlog includes another Skynet-series spacecraft to be launched, Skynet 5C.
The 4,100 kg (4.5 tons) Star One C1 passenger on tonight’s Ariane 5 mission was launched by Arianespace for satellite manufacturer Thales Alenia Space.
Equipped with C-, Ku- and X-band transponders, it will be utilized by the Star One subsidiary of Embratel to provide communications, multimedia and broadband Internet services for the Latin American market. Another spacecraft, Star One C2, also is to be orbited by Arianespace.
Le Gall provided details on Aranespace’s two remaining missions in 2007: a Dec. 14 Soyuz launch from Baikonur Cosmodrome for its Starsem affiliate, which will carry the Radarsat 2 satellite; followed several days later by the year-ending Ariane 5 flight with its Rascom 1 and Horizons-2 payloads.
The December Ariane 5 mission will mark the first time six launches of this workhorse vehicle have been performed in one year. Arianespace is accelerating the pace to accommodate its growing order book, with a stabilized rate of eight Ariane 5 launches annually to be reached by 2009.
Sirius 4 Launched On Proton/Breeze From Baikonur
A Sirius 4 communications satellite was launched yesterday from Baikonur Cosmodrome in Kazakhstan, satellite builder Lockheed Martin Corp. [LMT] announced.
The Proton/Breeze M launch vehicle was provided by International Launch Services (ILS).
Initial contact with the satellite was confirmed from the Lockheed Martin satellite tracking station in Uralla, Australia.
That Sirius 4 bird marks the 35th A2100 spacecraft designed and built by Lockheed Martin, according to the company. The spacecraft will be located at orbital location 5 degrees East and is expected to provide more than 15 years of service.
It will provide distribution of direct-to-home broadcast and interactive services across Scandinavia, Europe and Africa. The satellite features 46 active Ku-band high-power transponders in the BSS and FSS frequency band.
And it is equipped with an active Ka-band transponder for interactive applications in the Nordic and Baltic regions. The spacecraft is equipped with a sub-Sahara African beam to complement existing coverage of Africa, which is accomplished using six additional active Ku-band FSS transponders. Additionally, there is an interconnect payload that connects Africa and Europe with a second Ka-band transponder.
Lockheed Martin currently is building AMC-14 for SES AMERICOM, which is scheduled to be launched in the first quarter of 2008. Lockheed Martin successfully launched ASTRA-1L this year for SES ASTRA.
European Spacecraft To Fly Soon, Japanese Craft In 2009
The European Automated Transfer Vehicle, or ATV, will fly in January or February, and the Japanese H-II Transfer Vehicle will fly beginning in July 2009.
NASA may use these vehicles to transport U.S. astronauts to the International Space Station after the U.S. space shuttle fleet retires Sept. 30, 2010.
NASA also might hire Russian Soyuz vehicles to provide such taxi service to space, and perhaps might use commercial vehicles as well. (Please see story in this issue.)
Japan also has an orbiter circling the moon.
