Ariane 5 launches NSS-12 and THOR 6

Lifting off on time at 5:00 p.m. from the Spaceport in French Guiana, the Ariane 5 deployed the two television broadcast satellites during a mission lasting 31 minutes.

Ariane 5's payload lift performance for the daytime flight was a total of 9,515 kg., which included a combined total of approximately 8,700 kg. for the NSS-12 and THOR 6 spacecraft, plus the launch vehicle's dual-passenger dispenser system and satellite integration hardware.

The NSS-12 satellite was released first during today's launch, being deployed at 26 minutes into the flight. With a liftoff weight of approximately 5,620 kg., this spacecraft carries 40 C-band and 48 Ku-band transponders to provide telecommunications and direct-to-home television broadcast services for Europe, the Middle East, Africa, Asia and Australia.

It will be operated by SES WORLD SKIES from a geostationary orbit location of 57 deg. East, and is the second satellite launched by Arianespace this year for the SES group - following NSS-9, which was orbited by Ariane 5 in February.

THOR 6 was carried in the lower passenger position of Ariane 5's payload "stack," and it separated from the launcher at 31 minutes into the flight. Built in Europe by Thales Alenia Space, the 3,050-kg. satellite is fitted with 36 Ku-band transponders and will deliver high-power, direct-to-home television services from an orbital location of 1 deg. West.  When in service for Telenor Satellite Broadcasting, the capacity provided by THOR 6 will respond to the growing broadcast demands within Central and Eastern Europe and also provide additional capacity in the Nordic region.
