Arianespace Orbits Star One C2 and VINASAT-1 Second Successful Launch in 2008

KOUROU, French Guiana, April 18 /PRNewswire/ -- On Friday evening, April
18, Arianespace boosted two communications satellites into geostationary
transfer orbit (GTO): Star One C2 for Brazilian operator Star One, as part of
a turnkey contract with Thales Alenia Space, and VINASAT-1, built by Lockheed
Martin Commercial Space Systems (LMCSS) for operator Vietnam Posts and
Telecommunications Corporation (VNPT).
38th Ariane 5 launch, 24th success in a row
The latest successful launch of an Ariane 5, the second in 2008, comes
just five weeks after the flawless launch of the Jules Verne ATV (Automated
Transfer Vehicle) to the International Space Station. It confirms that
Arianespace's launch Service & Solutions continue to set the standard and
guarantee independent access to space for all stakeholders, whether national
or international space agencies, private or government operators.
Ariane 5 is the only commercial launcher in service today capable of
simultaneously launching two payloads, and gives Arianespace customers
unrivaled performance, flexibility and competitiveness.
A boost for a new customer
Arianespace is particularly proud of being selected to launch VINASAT-1,
Vietnam's first communications satellite. Through VINASAT-1, the Vietnam Posts
and Telecommunications Group (VNPT) will be able to offer a wide range of
telecommunications services across the country.
VINASAT-1 is the 39th Lockheed Martin platform to be launched by
Arianespace.
Long-standing customers and partners
Star One C2 is the eighth Brazilian satellite to use the European
launcher. Star One is the largest regional satellite service operator in Latin
America.
Arianespace and Thales Alenia Space have established relations of mutual
trust that reach back many years. Arianespace has launched nearly two-thirds
of all satellites built by Thales Alenia Space to date. Star One C2 is the
52nd platform built by Thales Alenia Space to be launched by Europe's Ariane
rocket.
