Summary Points
-
Sovereign Reusable Launch Development: Europe’s ArianeGroup is initiating a series of demonstrators, including Callisto, Themis, and Skyhopper, to establish advanced reusable launch capabilities.
-
Prometheus Engine Focus: The project revolves around the Prometheus rocket engine, designed for reusability, high thrust, and low costs, with testing already underway in France and Sweden.
-
Themis Vehicle Progress: The first Themis module, T1H, is prepared for upcoming launch and landing tests, focusing on successful vertical landings and efficient fuel use.
-
Long-Term Roadmap: A progressive approach will culminate in a full-stage recovery demonstration by 2027-2028, aimed at enhancing Europe’s independent access to space in the early 2030s.
Europe is on a mission to develop reusable rockets by the early 2030s. ArianeGroup, based in France, leads this ambitious initiative. Recently, Franck Koebel discussed their strategy at the International Astronautical Congress in Sydney, Australia.
The program includes three demonstrator vehicles: Callisto, Themis, and Skyhopper. Each vehicle intends to enhance Europe’s launch capabilities. Themis, for instance, features the T1H module. This 98.4-foot-tall vehicle has already reached Esrange Spaceport in Kiruna, Sweden.
Testing has commenced in France and Sweden, focusing on the high-thrust Prometheus engine. This engine runs on methane and liquid oxygen, making it both efficient and cost-effective. The first tests will demonstrate vertical landings, with a focus on stable descents and controlled fuel usage.
Koebel explained the progression of the project. Initially, Themis will use non-foldable landing legs. Later, the designs will incorporate foldable legs and multi-engine configurations. This approach allows engineers to learn and adapt at each stage.
The European Space Agency supports these efforts through the SALTO initiative. This collaboration falls under the European Union’s Horizon Europe program. The ultimate goal is to establish greater autonomous access to space for Europe.
The timeline suggests a full-stage recovery demonstration around 2027-2028. If successful, operational capabilities could follow shortly after. The advancements in this field could significantly impact technology development and daily life. Enhanced access to space can lead to improvements in satellite communication, environmental monitoring, and even global connectivity.
Koebel noted that the biggest challenge lies not in the science itself, but in mastering the necessary technologies. However, with continued investment and innovation, Europe aims to stand at the forefront of the space industry by the next decade.
