The Skynet 5A military communications satellite arrives for Arianespace's first Ariane 5 mission in 2007
 
http://www.arianespace.com/site/news/mission_up_367.html

The initial payload for Arianespace's first launch of 2007 arrived in French Guiana this week, with the touchdown of the United Kingdom's Skynet 5A satellite at Rochambeau International Airport near Cayenne.
 
A Ukrainian-built An-124 cargo jetliner flew the military communications platform from Europe, where Skynet 5A was built by EADS Astrium. After its landing at Rochambeau airport, the spacecraft was unloaded for its transfer by road to the Spaceport.

Skynet 5A is the first in a series of next-generation military relay satellites that will provide secure communications services for the British armed forces, NATO and a number of other countries. It will be operated for the U.K. Ministry of Defence by Paradigm Secure Communications, a commercial organization.

EADS Astrium has contracted to orbit the Skynet 5A, 5B and 5C spacecraft on Ariane 5, reinforcing Arianespace's role as the launch services provider of choice for a growing number of manufacturers and operators of military satellites.

As Skynet 5A begins its checkout process at the Spaceport, the Ariane 5 for Arianespace's initial flight of 2007 is now taking shape at the launch site. This upcoming mission will be another dual-satellite flight, with Skynet 5A being joined on the heavy-lift vehicle by India's INSAT 4B telecommunications satellite.

As announced earlier this week by Arianespace CEO Jean-Yves Le Gall, the company foresees launching six Ariane 5s in 2007, along with three Soyuz vehicles operated by its Starsem affiliate from Kazakhstan's Baikonur Cosmodrome.

Skynet 5A is installed on the payload interface adapter for its upcoming Ariane 5 launch
 
The first in a series of new-generation secure military communications satellites has made initial contact with Ariane 5 hardware as pre-launch preparations continue with the United Kingdom's Skynet 5A spacecraft at Europe's Spaceport in French Guiana.

 Built by EADS Astrium, Skynet 5A is one of two payloads to be orbited by the first Arianespace heavy-lift Ariane 5 mission of 2007. It was installed on the cone-shape payload adapter structure that serves as the satellite's interface with Ariane 5 (see photo at left).

EADS Astrium selected Ariane 5 to orbit all three Skynet 5-series satellites, underscoring the vehicle's role as a launcher of choice for a growing number of government and military payloads.

Skynet 5 spacecraft are to provide secure communications services for the British armed forces, NATO and a number of other countries. Their design is based on the new high-power E3000 variant of EADS Astrium's proven Eurostar satellite bus, which has accumulated over 200 years operational life. Each Skynet 5 will have a launch mass of approximately 5 metric tons, and is to operate with a payload power of 5 kW - which is up to 4 times more than the previous-generation Skynet 4 satellites.

The Skynet 5 platforms will be operated for the United Kingdom's Ministry of Defence by Paradigm Secure Communications Limited, a commercial organization that is a wholly-owned EADS SPACE Services subsidiary

For Arianespace's upcoming Ariane 5 launch, Skynet 5A will be joined by India's INSAT 4B telecommunications satellite on the dual-payload mission. The mission - Arianespace's first in 2007 - is scheduled for early March.

The second satellite for Ariane 5’s next mission is delivered to the Spaceport
 

Payload preparations for Arianespace’s upcoming heavy-lift Ariane 5 flight are in full stride following the arrival of India’s INSAT 4B telecommunications satellite at Europe’s Spaceport this week.
 
INSAT 4B was delivered to French Guiana by an Antonov An-124 cargo jetliner, which landed yesterday at Rochambeau International Airport near the capital city of Cayenne. The spacecraft then traveled to the Spaceport by road, and was removed from its protective shipping container inside the large S5 payload preparation building.

The Indian technical team for INSAT 4B also has come to French Guiana, where its members will perform the satellite’s final checkout process. Built by the Indian Space Research Organisation (ISRO), INSAT 4B carries 12 Ku-band transponders and 12 C-band transponders, and it will join one of the largest domestic communication satellite systems in operation over the Asia-Pacific region.

This is the second in India’s INSAT 4 series of relay platforms, and follows the INSAT 4A spacecraft – which was launched by Arianespace in December 2005 aboard another dual-payload Ariane 5 flight.

Accompanying INSAT 4B on the upcoming Ariane 5 mission is the United Kingdom's Skynet 5A secure military communications satellite, which is well advanced in its pre-launch checkout at the Spaceport.

Liftoff of the Ariane 5 with Skynet 5A and INSAT 4B is targeted for March 9, kicking off another active year of Arianespace commercial space launch missions.
 
I always consider space to be the FIRST frontier.

INSAT 4B "reaches out" at the Spaceport
 
http://www.arianespace.com/site/news/mission_up_370.html

Preparations for INSAT 4B's upcoming launch on Ariane 5 included deployment tests for the Indian telecommunication satellite's antennas at Europe's Spaceport this week.

As detailed in the images above, these tests validated the antenna opening sequence - providing a final pre-launch check of the process before INSAT 4B is encapsulated in Ariane 5's payload fairing. (Click on the images for a larger version).

INSAT 4B is equipped with a pair of transmit/receive antennas, which are installed on opposite sides of the cuboid-shaped spacecraft bus. One will handle the satellite's Ku-band relay duties, while the other is to accommodate its C-band services.

Built by the Indian Space Research Organisation, INSAT 4B is the second in India's INSAT 4 series of relay platforms. It follows INSAT 4A, which was launched by Ariane 5 in December 2005.

Arianespace has targeted March 9 for the upcoming liftoff of INSAT 4B, which will be orbited along with the United Kingdom's Skynet 5A secure military communications satellite.

Solar panel deployment for INSAT 4B is tested at the Spaceport

http://www.arianespace.com/site/news/mission_up_371.html

The solar panel deployment sequence for India's INSAT 4B telecommunications satellite was validated today during a full-scale test at Europe's Spaceport.

This test used an overhead latticework that helped support the solar panel's weight - simulating zero gravity conditions of space. The panel was allowed to open to its full length, confirming the correct extension process. Today's evaluation was performed in the Spaceport's S5 satellite preparation facility, and is detailed in the photo series above. (Click on the individual images for a larger version).

INSAT 4B has two deployable solar panels, which will give the satellite a 15.16-meter span when they are extended to their full length in orbit. The panels are designed to generate 5.5 kW of electrical power, the highest so far for India's family of telecommunications satellites.

Developed by the Indian Space Research Organisation, INSAT 4B is the second in the INSAT 4 series of relay platforms to be launched by Ariane 5. It follows the INSAT 4A payload - which was orbited in December 2005.

 Both INSAT 4 satellites are identical, carrying 12 Ku-band transponders to meet the requirement of direct-to-home (DTH) television services, plus 12 C-band transponders to augment the INSAT system's capacity for communication and DTH services.

 The Indian National Satellite (INSAT) system is a joint venture of the country's Department of Space, Department of Telecommunications, Meteorological Department, All India Radio and Doordarshan. Established in 1983, INSAT is one of the largest domestic communication satellite systems in the Asia/Pacific region.

INSAT 4B is scheduled to be launched March 9 on a dual-payload Ariane 5 mission that also will carry the United Kingdom's Skynet 5A secure military communications satellite.

Ariane 5 is ready for its dual-satellite payload
 
http://www.arianespace.com/site/news/mission_up_372.html

The heavy-lift launch vehicle for Arianespace's next Ariane 5 mission has moved to the Final Assembly Building at Europe's Spaceport, where it will be fitted with its dual-satellite payload.

This milestone marks the completion of Ariane 5's basic build-up, which began January 4 in the Launcher Integration Building. Rollout of the Ariane 5 to the final assembly facility occurred on February 20, when the vehicle was transferred along a 2.5-km. semi-circular rail line.

Our photo series (above) details the rollout process as the Ariane 5 rides atop its massive mobile launch table – which is one of two in service at the Spaceport for the heavy-lift vehicle.

Liftoff of the Ariane 5 is scheduled for the evening of March 9. It will be the Ariane launcher family's 175th mission – and the 31st for Ariane 5. The flight will carry India's INSAT 4B telecommunications satellite, along with the Skynet 5A secure military communications relay platform for the United Kingdom.

Arianespace's upcoming launch is to kick off a busy year for the company, which is targeting six heavy-lift Ariane 5 missions in 2007, along with three medium-class Soyuz launches by its Starsem affiliate.

Payload lift performance for the Ariane 5 will be 8,700 kg., of which 7,785 kg. is the combined mass of INSAT 4B and Skynet 5A. The remaining mass includes the satellite payload adapters and Ariane 5's multiple deployment system, which enables the launcher to perform its trademark dual-spacecraft launches.

The March 9 mission's liftoff is set at the opening of a 33-minute launch widow, which is detailed below:

   India's INSAT 4B is fueled for launch on Ariane 5    

             
          The INSAT 4B telecommunications satellite has completed its fueling process, marking another key step in preparations for Arianespace's upcoming Ariane 5 heavy-lift mission.

Fueling of the Indian telecommunications satellite was carried out in the S5A hall of Europe Spaceport's large S5 payload preparation facility.

 Both the INSAT 4B and its mission co-passenger - the United Kingdom's Skynet 5A satellite - are undergoing their final checkout in the S5 facility's multiple clean rooms.

INSAT 4B is equipped with a 440-Newton liquid apogee motor, which will raise the satellite to geostationary orbit after its deployment by Ariane 5. The apogee motor uses Mono Methyl Hydrazine (MMH) as fuel and Mixed Oxides of Nitrogen (MON-3) as oxidizer.

 Liftoff of the Ariane 5 with INSAT 4B and Skynet 5A is planned for March 9 during a 33-minute nighttime launch window.

The go-ahead is given for this weekend's Ariane 5 mission, while preparations begin for Arianespace's subsequent heavy-lift launch
 
http://www.arianespace.com/site/news/mission_up_377.html

Mission activity at Europe's Spaceport is in full swing as preparations advance for Arianespace's two upcoming Ariane 5 missions, which will place a total of four commercial payloads into orbit.
 
 
In parallel action at the Spaceport, the green light was given today for the liftoff of an Ariane 5 on Saturday (March 10) with the INSAT 4B and Skynet 5A payloads, while several kilometers away, another Ariane 5 began taking shape for Arianespace's subsequent dual-satellite mission.

Approval for the March 10 flight was given this afternoon following a successful completion of the Launch Readiness Review, which is one of the final milestones in preparations for every Ariane mission. The review brought together all players involved in the mission, and validated the readiness of the Ariane 5, its dual-satellite payload, the launch infrastructure at Europe's Spaceport and the network of ground tracking stations.

With the go-ahead, Ariane 5 is now cleared for its rollout tomorrow to the ELA-3 launch zone, where the final countdown will begin for a planned liftoff at 7:25 p.m. local time on March 10.

The mission will mark the 175th launch of an Ariane family vehicle, and it will kick off Arianespace's busy 2007 flight schedule.
