The launch readiness review approves Ariane 5's October 13 liftoff


The launch campaign for Arianespace's next heavy-lift Ariane 5 mission moved into its final phase today with the go-ahead for launch, which was given following the readiness review conducted at Europe's Spaceport in French Guiana.

This key milestone, which is performed prior to every Ariane launch, validates the readiness of Ariane 5, its satellite payload, the Spaceport's infrastructure and the down-range tracking stations.

All is now set for tomorrow morning's rollout of Ariane 5 from its Final Assembly Building to the ELA-3 launch zone. The vehicle is installed on one of two mobile launch tables available for Ariane 5, providing flexibility and reactivity for mission planning and operations

The upcoming mission is Arianespace's fourth Ariane 5 flight of 2006. Its DIRECTV 9S television broadcast is the largest of the two primary payloads on the launcher, with an estimated mass at liftoff of 5,535 kg. DIRECTV 9S will join the spacecraft fleet of U.S. digital television service provider DIRECTV, which serves more than 15.5 million customers.

Optus D1 will weigh in at 2,299 kg., and is to provide fixed communications and satellite broadcast services over Australia and New Zealand for Australia's Optus.

Also joining the two primary passengers is Japan's LDREX-2 auxiliary payload, which is a sub-scale demonstrator of a lightweight antenna reflector to be used on the Japanese ETS-8 engineering test satellite.

Arianespace rolls out its fourth heavy-lift Ariane 5 mission of 2006


Arianespace's heavy-lift Ariane 5 launcher is now in the launch zone, ready for tomorrow evening's liftoff from the Spaceport in French Guiana with a dual-satellite payload.

Rolling out from Spaceport's Final Assembly Building under mostly sunny French Guiana skies this morning, the Ariane 5 proceeded along a 2.8-km. dual-rail track to the ELA-3 launch zone, where it was positioned over the facility's massive flame ducts.

The Ariane 5 is installed on one of two mobile launch tables built for the workhorse launcher, which enables Arianespace to prepare two missions in parallel - a key element in the company's flexibility and reactivity.

With today's transfer of the Ariane 5, all is set for the final countdown leading to a liftoff tomorrow at the start of a one-hour launch window that opens at 5:56 p.m. (local time in French Guiana).

For Arianespace's fourth Ariane 5 flight of 2006, the mission will carry the DIRECTV 9S television broadcast satellite for U.S. digital television service provider DIRECTV, and the Optus D1 spacecraft for Australia's Optus.

DIRECTV 9S is installed in the upper payload position on Ariane 5, and will be deployed at 27 minutes into the flight. This will be followed by the Optus D1's separation approximately four minutes later.

The DIRECTV spacecraft is the larger of the launcher's two primary payloads, with a liftoff mass of about 5,535 kg. After its launch by Ariane 5, the Space Systems/Loral-built platform will join DIRECTV's satellite constellation that provides digital television service for more than 15.5 million customers.

Optus D1 has a mass at liftoff at 2,299 kg., and is to provide fixed communications and satellite broadcast services over Australia and New Zealand. This payload was built by Orbital Sciences Corporation.

The Ariane 5 also is carrying Japan's LDREX-2 auxiliary payload. This is a sub-scale demonstrator of a lightweight antenna reflector to be used on the Japanese ETS-8 engineering test satellite. Once the DIRECTV 9S and Optus D1 payloads are released, LDREX-2 will unfurl during the Ariane 5 mission in a multi-step process that takes approximately 45 minutes. When its deployment sequence is complete, this auxiliary passenger will be ejected from Ariane 5's upper stage, remaining in orbit for a period of time before the lightweight structure burns up in the atmosphere on reentry.

Final countdown underway for tonight's multi-payload Ariane 5 mission


Arianespace's fourth heavy-lift mission of 2006 is hours away from liftoff as preparations continue on track for its launch with two primary passengers and an auxiliary payload.

The final countdown activity today included an electrical system check on the launcher, followed by the fueling of Ariane 5's cryogenic core stage.

Weather at the Spaceport in French Guiana is excellent, with clear and sunny skies.

Liftoff of the Ariane 5 is set at the start of a one-hour launch window, which opens at 5:56 p.m. local time. The launcher is carrying the DIRECTV 9S television broadcast satellite for U.S. digital TV service provider DIRECTV, along with the Optus D1 telecommunications spacecraft for Australia's Optus.

Riding as an auxiliary payload on today's flight is Japan's LDREX-2 auxiliary payload. This is a sub-scale demonstrator of a lightweight antenna reflector for the Japanese ETS-8 engineering test satellite.

Launch day update: Ariane 5 lifts off from Europe's Spaceport


Arianespace's fourth multi-payload of 2006 has lifted off from the Spaceport in French Guiana.

The launcher is carrying the DIRECTV 9S television broadcast satellite for U.S. digital TV service provider DIRECTV, along with the Optus D1 telecommunications spacecraft for Australia's Optus.

DIRECTV 9S is to be deployed at approximately 27 minutes into the mission. This will be followed about three minutes later by the jettisoning of the SYLDA 5 multiple payload dispenser system, exposing Optus D1 for its release from Ariane 5 at 32 minutes after liftoff.

Optus D1 and DIRECTV 9S are accompanied on the Ariane 5 mission by Japan's LDREX-2 auxiliary payload - which will demonstrate the deployment sequence for a large satellite communications antenna. LDREX-2 is positioned at the base of Ariane 5's payload "stack," and its activation will occur after the separation of the two primary satellites.

Ariane 5 adds to its dual-success track record with another heavy-lift mission success


Arianespace maintained its 2006 mission pace with a successful Ariane 5 flight today that placed two primary satellites into geostationary transfer orbit.

After an on-time liftoff from Europe's Spaceport in French Guiana, the Ariane 5 went on to deploy DIRECTV 9S for U.S. digital TV service provider DIRECTV, along with the Optus D1 telecommunications spacecraft for Australia's Optus.

Today's launch occurred at 5:56 p.m. local time, providing a rare daytime view of the Ariane 5's ascent - as most missions occur after sunset. As it climbed into clear skies, the vehicle's trajectory was followed downrange by tracking cameras, providing an excellent view of its progress - including the jettison of its solid propellant boosters.

It was Arianespace's fourth dual-satellite Ariane 5 mission of 2006, bringing the total payload mass delivered by the workhorse launcher so far during this year to more than 31,670 kg. Since its introduction, Ariane 5 vehicles have orbited a combined total payload mass of over 600 metric tons.

DIRECTV 9S weighed in at approximately 5,535 kg., for today's mission. It was the sixth satellite to be launched by Arianespace for DIRECTV, Inc., the leading provider of digital multi-channel television service in the United States. The broadcast platform was built by U.S. satellite manufacturer Space Systems/Loral in Palo Alto, California. To date, a total of 32 Space Systems/Loral satellites have been booked with Arianespace, of which 31 have now been launched.

Optus D1 was released as the second payload in today's Ariane 5 mission sequence. This 2,350 kg. spacecraft is to provide fixed communications and broadcasting satellite services over Australia and New Zealand for Australia's Optus. The satellite was built by Orbital Sciences Corporation in Dulles, Virginia, and is based on the company's successful STAR series of smaller-sized spacecraft.

Riding as a piggyback payload on today's mission was Japan's LDREX-2, which is designed to validate the deployment process for a large, lightweight antenna reflector that will be used on Japan's ETS-8 engineering test satellite. Mounted to the base of Ariane 5's payload "stack," LDREX-2 was to be commanded through its unfurling sequence after the release of DIRECTV 9S and Optus D1.
