Ariane 5 has delivered two telecom satellites, SGDC and Koreasat-7, into their planned orbits. Arianespace announced the liftoff at 21:50 GMT (23:50 CEST, 18:50 local time) May 4, from Europe’s Spaceport in Kourou, French Guiana. The mission lasted about 36 minutes.

Brazil’s SGDC Geostationary Satellite for Communications and Defense, with a launch mass of 5735 kg, was the first to be released after about 28 minutes. The 3680 kg Koreasat-7 was released eight minutes later.

SGDC, operated by Telebras SA, will provide Brazil with broadband, new space technologies and strategic communications. The satellite has a design life of more than 18 years.

Koreasat-7, operated by ktsat, will provide telecommunications and broadcasting services over Korea, the Philippines, Indochina, India and Indonesia. The satellite has a design life of more than 15 years.

The payload mass for this launch was 10 289 kg. The satellites totalled about 9415 kg, with payload adapters and carrying structures making up the rest.

Arianespace CEO Stéphane Israël offered his congratulations to all parties involved during post-launch comments from the Spaceport’s Jupiter control room, and added that Flight VA236 “served two special customers and countries.”

The VA236 mission success was recognized by Rémy Le Thuc, Thales Alenia Space’s Telecommunications Projects Vice President, who added: “Thanks to Stéphane Israël and the Arianespace team. Ariane 5 operated like clockwork, as usual, which is definitely due to your team’s know-how and skill. Great job!”

“With our fourth successful launch of the year, and the second with an Ariane 5, Arianespace is on track to deliver 12 launches this year as originally scheduled,” added Israël.

Flight VA236 was the 92nd Ariane 5 mission.
