NASA, the European Space Agency (ESA), the Russian Federal Space Agency (Roscosmos) on Friday agreed to update the International Space Station launch schedule.
The target launch dates for the last planned space shuttle flight, STS-134 on Endeavour, will be Feb. 27 and the Automated Transfer Vehicle-2 (ATV-2) will be Feb. 15.
Roscosmos will continue to look at Soyuz launch and landing options to provide manifest robustness.
The agencies agreed to the changes during discussions at the International Astronautical Conference in Prague.
Arianespace, whose Ariane 5 rocket will launch ATV-2 into orbit from French Guiana, has confirmed its commitment to launch ATV-2 on February 15.
The STS-134 flight will deliver the Alpha Magnetic Spectrometer, or AMS, to the station. The AMS is a state-of-the-art cosmic ray particle physics detector designed to examine fundamental issues about matter and the origin and structure of the universe. The flight will include three spacewalks and the installation of the AMS to the exterior of the space station using both the shuttle and station arms.
ATV-2 – dubbed Johannes Kepler – is scheduled to dock on Feb. 26 to the station. The cargo craft is designed to deliver over seven tons of experiments, fuel, water, food and other supplies from Earth to the space station. While docked, ATV-2 also will use its thrusters to periodically boost the station’s orbit (which decays with time), and it can also be used for emergency maneuvers, such as those required if a piece of space debris is predicted to hit the station.
This capability saves critical attitude control propellant for the station. After about three and a half months, the ATV-2 will undock from the station and burn up harmlessly in the atmosphere over an uninhabited area of the Pacific Ocean.
The first ATV, Jules Verne, was launched in March 2008 and reentered the atmosphere in September 2008.
About Arianespace
Arianespace is the world’s leading launch Service & Solutions company, providing innovation to its customers since 1980. Backed by 24 shareholders and the European Space Agency, Arianespace offers an unrivalled family of launchers, comprising Ariane 5, Soyuz and Vega, and an international workforce renowned for a culture of commitment and excellence. As of October 1, 2010, Arianespace had launched a total of 283 payloads, including more than half of all the commercial satellites now in service worldwide. It has a backlog of 22 Ariane 5 and 18 Soyuz launches, equal to more than three years of business.
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.
