Launcher elements arrive in French Guiana for Arianespace's next Ariane 5 ECA dual-satellite mission
Following the Ariane 5 ECA's dual–payload mission success on March 11, initial activity has started for Arianespace's next heavy–lift launch — which is targeted for mid–May with the Satmex 6 and THAICOM 5 satellites.
Major elements for this Ariane 5 ECA vehicle are now at the Spaceport in French Guiana, having arrived from Europe last week aboard Arianespace's MN Colibri transport ship. The launcher components were unloaded at the Pariacabo dock and transferred by road to the Spaceport (see the photo, above).
Arianespace uses two ocean–going vessels — the MN Toucan and MN Colibri — to transport large launcher components from Europe to French Guiana. This ensures a regular, and highly controlled, shipment of elements for Ariane missions.
The Satmex 6 spacecraft to be orbited by Ariane 5 will be one of the most powerful telecommunications satellites to offer coverage over the Americas. Built by Space Systems/Loral in Palo Alto, California, Satmex 6 is to carry 36 C–band and 24 Ku–band transponders. Its coverage area will reach from the northern United States to southern Argentina, and is to be capable of handling the strong demand expected for video, data and voice transmission services.
Satmex 6 will be operated by Satelites Mexicanos, S.A. de C.V. (Satmex), a leading satellite services provider for Latin America.
Joining Satmex 6 on the Ariane 5 ECA launch in May will be the Alcatel Alenia Space–built THAICOM 5 spacecraft, which will provide telecom and television services throughout the Asia/Pacific region from its orbital position at 78.5 degrees East. It will be equipped with 14 Ku–band transponders and 24 C–band transponders, and is to have a launch mass of around 2,800 kg.
Operated by Shin Satellite Public Company Limited. of Thailand, THAICOM 5 will eventually replace the company's older THAICOM 1 and 2 satellites.

Mission preparations begin for Arianespace's second dual-satellite Ariane 5 flight of 2006
The heavy-lift Ariane 5 ECA for Arianespace's next dual-payload mission is now taking shape at the Spaceport in French Guiana.

The Ariane 5 ECA's cryogenic core stage is ready
to be positioned over the mobile launch table
inside the Spaceport's assembly building.
Preparations for this upcoming launch - scheduled for mid-May with the Satmex 6 and THAICOM 5 satellites - began with the positioning of Ariane 5's core cryogenic stage over the mobile launch table. This activity took place in the Launcher Integration Building, where Ariane 5's initial assembly will continue with the mating of its two solid boosters to the cryogenic stage.
The mid-May mission will mark Arianespace's second flight of 2006, and it follows the March 11 dual-payload success that placed the SPAINSAT and HOT BIRDTM 7A telecommunications platforms into highly accurate geostationary transfer orbits.
As with the next flight, the March 11 mission utilized the Ariane 5 ECA version - which has become the commercial launch service industry's true heavy-lift workhorse.
The Satmex 6 spacecraft to be orbited by the upcoming Ariane 5 launch will be operated by Satmex (Satelites Mexicanos, S.A. de C.V.), a leading satellite services provider in Latin America. Satmex 6 is one of the most powerful telecommunications satellites ever built for coverage over the Americas, with its C-band and Ku-band footprint reaching from the northern United States to southern Argentina.
The second passenger for the May mission is Thailand's THAICOM 5 spacecraft, which will provide telecom and television services throughout the Asia/Pacific region. It will join the satellite fleet operated by Shin Satellite Public Company Limited, eventually replacing the company's older THAICOM 1 and 2 relay platforms.

Arianespace's heavy-lift Ariane 5 ECA is fitted with its powerful upper stage
Assembly of the heavy-lift Ariane 5 ECA for Arianespace's mid-May mission marked another milestone with the integration of its ESC-A upper stage.

The ESC-A upper stage is hoisted inside the
launcher assembly building, with its Ariane 5
launcher partly visible in the background.
Produced by EADS Space Transportation, the cryogenic ESC-A upper stage is part of the propulsion system that provides increased lift capabilities for the Ariane 5 ECA. It is powered by Snecma Moteurs' proven third stage HM-7B engine - which provided years of reliable service on Ariane 4.
The Ariane 5 ECA's build-up is continuing inside the Spaceport's launcher assembly building, after which the vehicle will be transferred to the final assembly facility for integration of its dual-satellite payload.
Passengers for the mid-May flight are Satmex 6, to be operated by Satelites Mexicanos, S.A. de C.V., a leading satellite services provider in Latin America; and Thailand's THAICOM 5 spacecraft, which join the satellite fleet operated by Shin Satellite Public Company Limited.
The upcoming mission will be Arianespace's second launch of 2006, following the March 11 dual-payload success that used another Ariane 5 ECA to place the SPAINSAT and HOT BIRD™ 7A telecommunications platforms into accurate geostationary transfer orbits.

The basic Ariane 5 is complete with the installation of its guidance and control systems
The heavy-lift Ariane 5 ECA for Arianespace's next dual-payload mission has completed the initial build-up with the integration of its vehicle equipment bay - also known as the launcher's "brains."

The vehicle equipment bay is readied for integration
on the Ariane 5 ECA.
Supplied by EADS Astrium, this large ring-shaped component is equipped with the power distribution system, flight control unit, telemetry system and other elements that provide flight guidance, orientation and sequencing during the Ariane 5's mission.
The vehicle equipment bay's advanced systems include highly precise laser gyros - which help give Ariane 5 the most accurate orbital injection of any commercial launch system. This ensures spacecraft payloads are placed in the right orbit, every time, thereby maximizing the satellites' revenue-producing operations during their operational lifetime.
With the vehicle equipment bay now installed, preparations are continuing with the Ariane 5 ECA inside the Spaceport's launcher integration building at French Guiana. The vehicle subsequently will be transferred to the final assembly building, where the mission's two payloads will be integrated.
Passengers for the upcoming flight, scheduled for May, are Satmex 6 and THAICOM 5. Satmex 6 will be operated by Satelites Mexicanos, S.A. de C.V., a leading satellite services provider in Latin America; while Thailand's THAICOM 5 spacecraft will join the satellite fleet operated by Shin Satellite Public Company Limited.
