Enabling & Support
Europe’s Ariane 5 has delivered two telecom satellites, SES-17 and Syracuse-4A, into their deliberate orbits.
Arianespace introduced liftoff at 03:10 BST (04:10 CEST, 23:10 native time on 23 October) from Europe’s Spaceport in Kourou, French Guiana, for a mission lasting about 38 minutes.“For this launch, we increased the Ariane 5 fairing volume by attaching a 1.5 m raising cylinder to accommodate these two very large, stacked satellites. The development and qualification of this adaptation was funded by ESA. Today’s launch of 11.2 t to geostationary transfer orbit is a record performance for Ariane 5,” mentioned Daniel de Chambure, ESA’s Acting Head of Ariane 5 adaptation and future missions.

SES-17, with a launch mass of 6411 kg, within the higher berth of the fairing was launched first.Following a collection of burns managed by Ariane’s laptop, the Sylda construction encasing the 3853 kg Syracuse-4A payload was jettisoned. Syracuse-4A was launched about two minutes later in direction of its personal geostationary switch orbit.SES-17 is owned and operated by SES. It will ship broadband protection over the Americas, the Caribbean and over the Atlantic Ocean and is optimised for business aviation.Syracuse-4A, for France’s DGA (Direction générale de l’armement) defence procurement company, will present safe communications between deployed armed forces and also will assist NATO and European-led operations.Both satellites have a design lifetime of about 15 years.The efficiency requested for this Ariane launch was 11 210 kg. The two satellites totalled about 10 264 kg, with payload adapters and carrying constructions making up the remaining.“Ariane 5 demonstrates continuous improvement with each launch. The success today of launch VA255 and the success of VA254 last July were crucial to move towards Ariane 5’s December launch carrying the James Webb Space Telescope,” commented Daniel Neuenschwander, ESA Director of Space Transportation.Flight VA255 was the 111th Ariane 5 mission.
About Ariane 5
Ariane 5 is operated by Arianespace at Europe’s Spaceport. It can carry payloads weighing greater than 10 tonnes to geostationary switch orbit and over 20 tonnes into low Earth orbit. Its efficiency completely enhances that of Europe’s Vega light-lift launch car, and Soyuz.Europe’s next-generation Ariane 6 rocket will finally change Ariane 5. Available in two variations, it will likely be able to a variety of missions to any orbit.
