On June 16, Arianespace will launch Heinrich-Hertz-Satellit, designed and manufactured by OHB System on behalf of the German Space Agency with funding of the German Federal Ministry of Economic Affairs and Climate Change and with the participation of the German Federal Ministry of Defence, and SYRACUSE 4B, designed and manufactured by Airbus Defence and Space and Thales Alenia Space for the French Armament General Directorate (DGA). The mission will place both payloads into a Geostationary Transfer Orbit. Flight VA261 will be the 117th and last mission of Ariane 5, the European workhorse which will be replaced by the new European heavy launcher Ariane 6. On Friday, June 16, 2023, between 6:26 p.m. and 08:01 p.m. local time (between 09:26 p.m. and 11:01 p.m. UTC), Arianespace will launch an Ariane 5 carrying Heinrich-Hertz-Satellit for the German Space Agency and SYRACUSE 4B for the French Armament General Directorate (DGA). The mission, designated VA261, will last 33 minutes and 31 seconds and place both payloads into a Geostationary Transfer Orbit. For this launch, Arianespace will serve, for the first time, the German Space Agency on behalf of the German Government by orbiting the Heinrich-Hertz-Satellit, as well as the French Ministry of Defence, owner of the SYRACUSE 4B satellite. The latter is part of the SYRACUSE defence program together with the SYRACUSE 4A satellite, also launched by an Ariane 5 vehicle in October 2021. Both payloads will serve the need for a higher and better telecommunications system, reserved to military and institutional uses. The Heinrich-Hertz-Mission is the first dedicated German telecommunications satellite-based mission that will be used to conduct research and to test new technologies and telecommunications scenarios. The technologies on board are meant to respond smartly and flexibly to future challenges, to support future telecommunications scenarios and to be adapted from Earth to address new technical requirements and market needs. The mission is managed by the German Space Agency on behalf of the German Federal Ministry for Economic Affairs and Climate Action (BMWK) and with the participation of the German Federal Ministry of Defence (BMVg). The Heinrich-Hertz-Satellit was mainly developed and built by OHB System. SYRACUSE 4B satellite, delivered by the DGA to the French Air and Space force and the French Space Commander, will allow, in conjunction with the SYRACUSE 4A satellite to connect the armed forces together when deployed. On the ground, at sea, on the air and even in space, militaries needs secured, militaries need secured and powerful communication means in order to be able to exchange information with the command center. Thanks to its state-of-the-art equipment (active antenna and digital transparent processor), SYRACUSE 4B will guarantee a high resistance to extreme military threats. At the service of France’s sovereignty, the satellite will also support NATO operations. To produce SYRACUSE 4B and SYRACUSE 4A satellites and their associated payloads, Airbus Defence and Space and Thales Alenia Space joined forces to contribute their expertise to this high-end military telecommunications programme.       The launch at a glance: → 347th launch for the Arianespace family of launchers. → Heinrich-Hertz-Satellit and SYRACUSE 4B will be the 1152nd and 1153rd satellites to be launched by Arianespace. → 117th launch of Ariane 5 overall.

The 116th Ariane 5 launch, operated by Arianespace, successfully placed the JUICE space probe in an escape orbit. Europe’s Ariane 5 heavy-lift launcher, for which ArianeGroup is the lead contractor, once again demonstrated its exceptional reliability. This will be Europe’s first mission to the Jovian system. Its passenger, JUICE, will spend at least three years observing Jupiter’s icy moons, Europa, Ganymede, and Callisto. On Friday, April 14, 2023 at 09:14 am local time, an Ariane 5 launcher, operated by Arianespace, successfully lifted off from Europe’s Spaceport in Kourou, French Guiana, carrying the European Space Agency (ESA) JUICE space probe. The spacecraft, built by Airbus Defence and Space for ESA, will carry out Europe’s first mission to Jupiter. It will spend at least three years making detailed observations of the planet’s icy moons: Europa, Ganymede, and Callisto, which will arrived in july 2031. JUICE will study the moons as potential habitats for life, addressing two key questions: what are the conditions for planet formation and the emergence of life, and how does the solar system work? Stéphane Israël, CEO of Arianespace, said: “Arianespace is honored to have been entrusted with this launch, the first European mission to Jupiter, and to play a part in expanding our understanding of the solar system and the necessary conditions for the emergence of life. In preparing for this mission, we have worked hand in hand with ESA, Airbus Defence and Space, ArianeGroup, and French space agency CNES. I take this opportunity to thank all the teams who have given so much for 10 years to bring us to today’s successful result. And good luck to JUICE for the incredible journey it is about to embark on!” “With the successful launch of the JUICE space probe, Ariane 5 has once again made its contribution to European space history. This exceptional mission benefited twice over from ArianeGroup’s expertise: we not only built and prepared Ariane 5 for this mission, but we are also involved in the JUICE spacecraft as we developed, supplied, and tested the entire propulsion system which will enable the probe to make its eight-year journey to Jupiter. I want to thank the teams from ArianeGroup and Arianespace, together with all our European partners, for this latest success of the Ariane launcher. Our launcher’s high reliability is due to the unfailing cooperation between the industry, ESA, and CNES, the guarantee of Europe’s independent access to space,” said Martin Sion, CEO of ArianeGroup. The propulsion system for the JUICE spacecraft was developed, built, and integrated in Germany by ArianeGroup’s Orbital Propulsion teams, and comprises the 400 N main engine to be used for Jupiter orbit injection, 20 small thrusters, and two titanium propellant tanks. After this mission, one Ariane 5 launch remains before Ariane 6 takes up the baton, supporting Europe’s institutional missions and meeting the rapidly growing needs of the commercial market. The Ariane 5 heavy-lift launcher is an ESA program carried out in cooperation between public institutions and industry across 12 European partner countries. ArianeGroup is the lead contractor for the development and production of Ariane 5, as well as being responsible for launcher preparation operations up to lift-off. As prime contractor for Ariane 5 and Ariane 6, in charge of development and production, ArianeGroup is at the head of a vast industrial network of more than 600 companies, including 350 small and medium-size enterprises (SMEs). ArianeGroup delivers a flight-ready launcher on the launch pad to its subsidiary Arianespace, which markets and operates Ariane 5 from Europe’s spaceport in French Guiana. During launch campaigns, Arianespace works closely with the French space agency (CNES), the design authority for Ariane 5 and responsible for the satellite preparation facilities and the launch base.   THE LAUNCH AT A GLANCE: 346th launch operated by Arianespace More than 1150 satellites launched by Arianespace 1st launch operated by Arianespace in 2023 This launch was carried out on April 14, 2023 from the European Spaceport in Kourou, French Guiana at 09:14 am local time (12:14 pm UTC) 116th Ariane 5 launch fro mthe CSG 6058kg is the total payload carried by the launched for this mission 90th consecutive launch with nominal operation of the Vulcain 2 main stage engine 116th consecutive launch with nominal operation of the solid boosters 156th consecutive launch with nominal operation of the HM7B upper stage engine   About Arianespace : Arianespace uses space to make life better on Earth by providing launch services for all types of satellites into all orbits.
