Arianespace’s second launch of 2023 with the last Ariane 5 ever will place its satellite passengers into geostationary transfer orbit. The launcher will be carrying a total payload of approximately 7680 kg. The launch will be performed from Kourou, French Guiana.   PAYLOADS : Heinrich-Hertz-Mission : As the need for global communications bandwidth rapidly increases, so do the demands on communications satellites. Communications satellites capable of handling modern and future demands must therefore make use of increasingly high-performance technologies. The Heinrich Hertz mission is the first dedicated German communications satellite for researching and testing new technologies and communications scenarios. The technologies on board will respond smartly and flexibly to future satellite communications challenges, support future communications scenarios and be adapted from Earth to address new technical requirements and market conditions. The mission is thus making an important contribution to the information society in Germany. The Heinrich Hertz mission is managed by the German Space Agency at DLR in Bonn on behalf of the German Federal Ministry for Economic Affairs and Climate Action (BMWK), with the participation of the German Federal Ministry of Defence (BMVg). OHB-System AG was contracted to develop and build the satellite. A total of 42 partners are participating in the mission, of which 14 are involved in the scientific payload.   • Heinrich-Hertz-Satellit will be the 28th OHB System AG satellite to be launched by Arianespace. • VA261 is the first mission operated by Arianespace for the German Space Agency   DID YOU KNOW ? The Heinrich Hertz mission is a pioneer. The German smart satellite is capable of processing information on board while in space. Its two onboard processors are used for digital signal processing in orbit and can be flexibly reprogrammed from Earth. As a result, new communications scenarios can be developed and tested using the satellite.   SYRACUSE 4B : Ordered by the French defense procurement agency (DGA), this satellite will enable the French Armed Forces to remain permanently connected during deployments. Whether at sea, in the air or on land, military personnel need powerful, secure communications to exchange information with the command center. Thanks to state-of-the-art equipment (anti-jamming antenna, digital processor, etc.), SYRACUSE 4B will be totally protected against the most extreme jamming methods. Built to defend French sovereignty, the satellite will also be able to support operations led by NATO and the EU. The SYRACUSE IV military telecommunications satellite system, comprising 2 satellites, SYRACUSE 4A and 4B, is being built for the DGA by an industrial consortium formed by Thales Alenia Space and Airbus Defence and Space. Thales Alenia Space is responsible for the SYRACUSE 4A satellite, based on its 100% electric SpaceBus Neo platform, and for the two payloads. Airbus Defence and Space is responsible for the SYRACUSE 4B satellite, based on the all-electric version of the Eurostar platform, and supplies critical elements of both payloads. Thales Alenia Space is the lead contractor responsible for relations with the French Ministry for the Armed Forces.   • SYRACUSE 4B is the 49th satellite to be launched by Arianespace for French insitutions. • The satellite will be the 141st satellite manufactured by Airbus Defence and Space to be launched by Arianespace.   DID YOU KNOW ? The SYRACUSE IV program (Roman numerals to designate the complete system) includes the two military satellites (SYRACUSE 4A and 4B) and the ground stations for communications within theaters of operation and with mainland France.

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.
