Arianespace release
Ariane 5 delivers JCSAT-10 and Syracuse 3B to orbit on a dual-satellite
launch success
Arianespace provided another demonstration of Ariane 5's mission
capability and flexibility with tonight's launch of a mixed
commercial/military satellite payload in the vehicle's third flight of 2006.
After an on-time lift-off at 7:15 p.m. from Europe's Spaceport in French
Guiana, the heavy-lift Ariane 5 delivered Japan's JCSAT-10
telecommunications spacecraft and the European Syracuse 3B secure
military relay platform into geostationary transfer orbit.
Tonight's flight was Ariane 5's 28th mission, and marked its 14th
consecutive success – underscoring the launcher's maturity. JCSAT-10 was
installed in the upper payload position on Ariane 5, and was released
approximately 27 min. into the mission. This was followed some 5 minutes
later by the separation of Syracuse 3B, which occupied the lower slot in
the payload "stack."
"Tonight's success is particularly exemplary, and perfectly illustrates
why we have launched a total of 237 satellites during the past 26 years
– which, by far, is a world record," said Arianespace Chief Executive
Officer Jean-Yves Le Gall in post-launch comments at the Spaceport's
Jupiter control center.
Le Gall noted that JCSAT-10 is the sixth satellite entrusted by Japan's
JSAT Corporation to Arianespace for launch. It follows the recent
orbiting of JCSAT-9 within the framework of the Launch Services Alliance
mission industrial grouping – in which Arianespace is a founding member.
JCSAT-10's liftoff mass was approximately 4,050 kg. and it will be
operated from an orbital slot of 128 deg. East to provide fixed
satellite services (FSS) for Japan, the Asia-Pacific region and Hawaii.
It carries a mixed relay payload of 30 Ku-band transponders and 12
C-band transponders, and was built by Lockheed Martin Commercial Space
Systems.
In addition, Le Gall said this latest Arianespace mission success
reinforces Ariane's role in providing independent access to space for
governmental and military spacecraft such as Syracuse 3B. He noted
Syracuse 3B was the 27th military payload launched by Ariane, of which
the three most recent were lofted by Ariane 5s during the past 10 months.
Built by Alcatel Alenia Space, Syracuse 3B will operate nine SHF (super
high frequency) and six EHF (extremely high frequency) secure relay
channels, providing communications with defense forces and upgrading the
relay links between French political and military authorities and
operating units deployed worldwide. It will be positioned at an orbital
slot of 5 deg. West, becoming part of France's Syracuse III
third-generation military communications system – joining the Syracuse
3A satellite launched by an Ariane 5 last October.
Le Gall announced that Arianespace will keep up its 2006 mission pace by
performing the next Ariane 5 launch on September 19. This Ariane 5 ECA
will carry the DIRECTV 9S television broadcast satellite for DIRECTV of
the U.S., along with the Optus D1 telecommunications spacecraft for
Australia's Optus. An auxiliary payload also will be carried on the
flight: the LDREX deployable antenna demonstrator from JAXA (the Japan
Aerospace Exploration Agency).
