Ariane 5 July 05, 2023
A Franco-German success for the final Ariane 5 mission
The 117th and final Ariane 5 launch, operated by Arianespace, placed two telecommunications satellites in orbit: Heinrich-Hertz-Satellit for the German government and SYRACUSE 4B for the French Armament General Directorate (DGA).
Europe’s Ariane 5 heavy-lift launcher, for which ArianeGroup is the lead contractor, is taking its place in the annals of history and leaves an exceptional heritage of expertise and reliability to its successor Ariane 6.
Ariane 6 will now take over from Ariane 5, in carrying out Europe’s institutional space missions and responding to the growing demands of the commercial market.
On July 5, 2023 at 7:00 p.m. local time, Ariane 5, operated by Arianespace, lifted off flawlessly from Europe’s spaceport in Kourou, French Guiana, carrying Heinrich-Hertz-Satellit for the German government and SYRACUSE 4B for the French Ministry of Defence..
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.
The SYRACUSE 4B satellite is part of the SYRACUSE IV program carried out under the leadership of the DGA in collaboration with the French Air and Space Force, and for the Space Command (CdE). Together with SYRACUSE 4A, it will enable French armed forces to remain permanently connected when they are deployed on operations. At sea, in the air, or on land, the armed forces need powerful and secure communications systems to be able to exchange information with theIr command center. Thanks to state-of-the-art equipment including an anti-jamming antenna and a digital onboard processor, SYRACUSE 4B will be fully protected against the most severe military threats. It will help guarantee French national sovereignty while also supporting NATO operations. Airbus Defence and Space and Thales Alenia Space joined forces to develop the SYRACUSE 4A and SYRACUSE 4B satellites so that the program could benefit fully from their combined expertise. .
“This 117th and last Ariane 5 mission is emblematic in several respects. Ariane 5 has just deployed two telecommunications satellites, SYRACUSE 4B and Heinrich-Hertz-Satellit, for France and Germany, the first two contributors to the Ariane program,” said Stéphane Israël, CEO of Arianespace. “This mission is also emblematic of Ariane 5’s ability to perform dual launches, which constitutes the very core of its success, with 197 satellites placed in geostationary orbit out of a total of 239 satellites deployed. Over its career, Ariane 5 has served 65 institutional and commercial customers from 30 countries. Ariane 5’s success heralds a promising career for Ariane 6.”
This launch also marks the end of the remarkable career of the HM7 upper stage engine, which flew on the first Ariane 1 and on the final Ariane 5. It helped power Ariane launchers 228 times, without ever failing. This veteran of spaceflight has been a crucial element in the European space adventure. It will be replaced on Ariane 6 by the re-ignitable Vinci engine.
“Ariane 5 is now taking its place in the annals of global space history. This final successful mission demonstrates once again its supreme reliability in the service of European autonomy and rounds off an exceptional career distinguished by a succession of technological and industrial achievements. I share the emotion of all the employees at ArianeGroup, Arianespace, the French and European space agencies CNES and ESA, and all our European partners, who have contributed to its success over the course of these 27 years,” said Martin Sion, CEO of ArianeGroup. “Together we are now taking up the challenge of Ariane 6, the beneficiary of the experience acquired with Ariane 5. It will be able to evolve and play a full role in guaranteeing independent, sustainable access to space for Europe, in a context of major strategic, economic and environmental challenges, to meet the needs of its institutional and commercial customers.”
Leading up to its inaugural flight, Ariane 6 is currently passing a series of key milestones in Europe and in French Guiana. Even more versatile and competitive, Ariane 6 will carry out its first missions with a rapid production ramp-up, supporting Europe’s institutional missions and meeting the swiftly growing demands 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 states.
ArianeGroup is the lead contractor for the development and production of the Ariane family of launchers. It is responsible for Ariane 5 and Ariane 6 preparation operations up to lift-off. 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 Ariane 5 launch campaigns, Arianespace works closely with the French space agency (CNES), the design authority for the launcher and responsible for the satellite preparation facilities and the launch base.

Arianespace signs Memorandums of Understanding with three microlauncher companies
Arianespace signed three distinct Memorandums of Understanding (MoU) with Dark, Orbex and PLD Space to study possible future cooperation to answer its customers’ requests.
The small satellite market is booming and is made of always more diverse requirements and solutions, some of them in very specific orbits. Even if the majority of this market can be satisfied by ride-share flights on Ariane 6 and Vega C, micro and mini launchers can complement Arianespace portfolio to provide innovative technologies and services to new customers. Arianespace announces that it has signed three Memorandums of Understanding (MoU) with Dark, Orbex, and PLD Space to work on possible collaboration to answer to its customers’ requests.
Dark is a French company developing a multi-mission platform able to launch up to 300 kilograms in Sun-Synchronous Orbit (SSO) at an altitude of 500 kilometers. Their solution is based on an air-launched rocket integrated under a plane, thus enabling launches from airports. Dark maiden flight is targeted in 2028.
Orbex is a European company based in Scotland, developing a microlauncher called Prime, with a reusable first stage, that will be able to offer dedicated and rideshare launch opportunities to satellites weighing up to 200 kilograms targeting a Low Earth Orbit. This launcher is equipped with 3D-printed rocket engines that use a renewable bio-propane fuel to limit carbon emissions. Orbex operates from Sutherland Spaceport in Scotland. Prime maiden flight is targeted to take place in late 2024.
PLD Space is a Spanish company, developing the MIURA 5 microlauncher, based on a reusable Lox/kerosene first stage which enables dedicated rideshare and piggyback launches for its customers. This vehicle is ideally positioned for small satellites ranging from CubeSats to payloads weighing up to 540 kilograms, and deploying these in Sun-Synchronous Orbit (SSO) at an altitude of approximately 500 kilometers. PLD Space targets launches from Huelva in Spain and from the French Guiana Space Center. MIURA 5 maiden flight is targeted late 2025.
In order to lay the foundations for future collaborations, these MoUs establish the terms and conditions of the various avenues of cooperation, all based on a non-exclusivity basis. Arianespace and all three companies agree to study the possibility, when applicable, to offer to their clients:
• joint offers, allowing for optimized launch solutions to address deployment of small constellations or combination of multiple small satellites.
• their respective launch solutions as possible back-ups.
This approach aims at increasing the joint capabilities and flexibility of all the parties’ services.
