Integration of the HOT BIRD™ 9 payload is completed for Ariane 5's year-end mission

December 10, 2008

 
The upper payload component for Arianespace’s upcoming dual-satellite Ariane 5 mission is now complete at Europe’s Spaceport, following the encapsulation of HOT BIRD™ 9 inside the launcher’s payload fairing.

HOT BIRD 9 will be the upper passenger on Ariane 5’s December 20 mission, and is to be deployed approximately 27 minutes into the flight.  This satellite is mounted atop a SYLDA dispenser system, which will be installed over the second passenger – W2M – to complete the payload “stack” atop the Ariane 5’s core cryogenic stage.

The photo at left shows the encapsulation process, which occurred earlier today in the Ariane 5 Final Assembly Building.  The payload fairing is positioned above the integration rig, ready to be lowered over HOT BIRD 9 and the SLYDA dispenser below it.

Arianespace’s sixth – and final – mission of 2008 will be at the service of European telecommunications operator Eutelsat, which is to operate both the HOT BIRD 9 and W2M satellites.

HOT BIRD 9 was built by EADS Astrium, and will have a liftoff mass of 4,880 kg.  Configured with 64 Ku-band transponders, this high-power satellite will serve as a relay for digital and new high-definition TV channels, as well as interactive services.  From its location at Eutelsat’s premium video neighborhood orbital slot of 13 deg. East, HOT BIRD 9’s coverage area is to extend throughout Europe, and also reach North Africa and the Middle East. 

W2M was developed by a European-Indian alliance of EADS Astrium and ANTRIX (the commercial arm of the Indian Space Research Organisation), and is to have a liftoff mass of 3,460 kg.  The spacecraft will be positioned at an orbital slot of 16 deg., providing both television and radio broadcasting services.

Final payload integration begins on Ariane 5 for its sixth flight of 2008

December 11, 2008

http://www.arianespace.com/news-mission-update/2008/549.asp
 
Preparations for Arianespace’s year-end launch of 2008 entered their final phase today with the startup of payload integration on the Ariane 5 at Europe's Spaceport in French Guiana.

During activity in the Ariane 5 Final Assembly Building this morning, the W2M satellite was installed atop the launcher’s core cryogenic stage.  W2M is one of two satellites to be orbited on December 20 for the European-based Eutelsat telecommunications provider, along with its HOT BIRD™ 9 relay platform.

W2M is a multi-national spacecraft, developed and produced by a European-Indian alliance of EADS Astrium and ANTRIX (the commercial arm of ISRO – the Indian Space Research Organisation).  Astrium is prime contractor, with responsibility for overall program management and the satellite’s communications payload.   ISRO provided the satellite bus – which is based on the flight-proven I-3K spacecraft design – and also handled W2M’s integration and testing.   

Liftoff mass of W2M will be 3,460 kg., and the spacecraft has an operating lifetime of more than 15 years.  After its deployment by Ariane 5, W2M is to be positioned at an orbital slot of 16 deg. East.  It will typically operate 26 transponders in Ku-band, and up to 32 depending on the selected operational modes. 

The satellite is designed to deliver a wide range of services, from television broadcasting to data networks and broadband. Its fixed beam covers Europe, North Africa and the Middle East, and the steerable beam is capable of being re-oriented in orbit to meet market requirements – notably for Africa and central Asia.

Joining W2M on Ariane 5’s December 20 launch is the 4,880-kg. HOT BIRD 9 spacecraft, which was built by Astrium and is configured with 64 Ku-band transponders.  This high-power satellite will handle relay duties for digital and new high-definition TV channels, as well as interactive services.  To be located at Eutelsat’s premium video neighborhood orbital slot of 13 deg. East, HOT BIRD 9 will provide coverage throughout Europe, and also is to reach North Africa and the Middle East.

Launch Window:

Kourou, French Guiana:
From 6:51 p.m. to 7:50 p.m. on December 20, 2008

UTC:
From 9:51 p.m. to 10:50 p.m. on December 20, 2008

Arianespace’s sixth Ariane 5 of 2008 completes its assembly at the Spaceport in French Guiana
December 15, 2008

http://www.arianespace.com/news-mission-update/2008/550.asp (with photo)
 
Ariane 5’s payload fairing with the HOT BIRD 9 satellite is lowered into position over W2M, which is installed atop the launch vehicle.
 
The final checkout of Arianespace’s sixth Ariane 5 for launch in 2008 is now underway following the completion of payload integration for its two Eutelsat satellite passengers.

This mission’s upper spacecraft – HOT BIRD™ 9 – was positioned atop Ariane 5 last Friday, forming the dual payload “stack.”  HOT BIRD 9 is encapsulated in the Ariane 5’s protective payload fairing, and has been mounted atop a SYLDA payload dispenser system.  Positioned below HOT BIRD 9 is the W2M spacecraft, which was integrated December 11 on Ariane 5’s core cryogenic stage.

Liftoff for Arianespace’s year-ending mission is scheduled December 20 at the start of a 59-minute launch window that opens at 6:51 p.m. local time in French Guiana.

Ariane 5’s payload lift performance on the upcoming flight is 9,220 kg. – which includes the satellite’s combined 8,340 kg. mass, along with the accompanying integration hardware and the SYLDA dispenser system.

After its deployment by Ariane 5, HOT BIRD 9 will provide the relay of digital and new high-definition TV channels, along with interactive services.  The satellite is to be placed at Eutelsat’s premium video neighborhood orbital slot of 13 deg. East. 

W2M will be positioned at an orbital slot of 16 deg. East, providing television and radio broadcasting services for Eutelsat.

The go-ahead is given for Arianespace's final Ariane 5 launch of 2008

The sixth Ariane 5 mission of this year was cleared for its December 20 liftoff following today’s launch readiness review, which was held at the Spaceport in French Guiana.

This review is one of the final key milestones of any Ariane 5 launch, and it validated the readiness of Arianespace’s heavy-lift vehicle, its dual satellite payload for Eutelsat, the infrastructure at Europe’s Spaceport in French Guiana and the network of downrange tracking stations.

The approval clears Ariane 5 for its transfer to the ELA-3 launch zone tomorrow, followed by the countdown to liftoff on Saturday at 6:51 p.m. local time at the Spaceport....

Ariane 5 is poised for liftoff with Eutelsat's HOT BIRD™ 9 and W2M satellites

http://www.arianespace.com/news-mission-update/2008/552.asp

December 19, 2008

The ELA-3 launch zone at Europe’s Spaceport welcomed its 42nd Ariane 5 today as the heavy-lift vehicle with Eutelsat’s HOT BIRD™ 9 and W2M satellites rolled out for a liftoff tomorrow evening on the final Arianespace mission of 2008.

Sunny skies greeted the Ariane 5 ECA as it departed the Final Assembly Building at 11:00 a.m. for a 2.8-km. transfer to the ELA-3 launch area.  Riding atop one of two mobile launch tables available for Ariane 5 mission operations, the vehicle arrived on the launch pad 1 hr. 15 min. later, where it was secured in place.

Tomorrow’s liftoff is scheduled at the 6:51 p.m. opening of a 59-minute launch window, with the two Eutelsat satellites to be deployed during a flight lasting approximately 32 minutes.

HOT BIRD 9 is installed in the upper position of Ariane 5’s dual payload “stack,” and will be released first during the mission sequence.  This spacecraft was produced by EADS Astrium and carries 64 Ku-band transponders for the broadcast of digital and new high-definition TV channels, as well as interactive services.  After its deployment by Ariane 5, it will be located at Eutelsat’s premium video neighborhood orbital slot of 13 deg. East, with a coverage area extending throughout Europe, as well as to North Africa and the Middle East. 

The W2M satellite, which is carried in Ariane 5’s lower passenger slot, was built by a European-Indian joint effort involving EADS Astrium and ANTRIX (the commercial arm of the Indian Space Research Organisation).  W2M will be positioned at an orbital slot of 16 deg. East, and is to provide both television and radio broadcasting services for Eutelsat.

Tomorrow’s Ariane 5 mission will mark the 42nd launch of this workhorse commercial launcher, and is the sixth flight performed by Arianespace in 2008.
