Sener secures a contract with ESA to develop a reusable European rocket.

Sener has joined the group of contractors for the Themis program, implemented by the European Space Agency (ESA) in collaboration with ArianeGroup. The objective of this program is to develop a reusable rocket demonstrator capable of vertical landing and relaunching.

The industrial engineering and technology group Sener has been awarded a contract in the Themis program, implemented by the European Space Agency (ESA) in collaboration with ArianeGroup. The contract award for the Themis project opens the door for Sener to participate in one of ESA's most ambitious programs. The project is strategically important for the development of reusable rockets and represents a significant step toward greater European independence in access to space.

Rocket demonstrators, like Themis, allow new technologies to be field-tested before they are deployed on operational rockets used in missions. They help reduce potential risks and accelerate the development of competitive launch systems.

From Poland, SENER engineers are responsible for the design and production of two essential components for the operation of the grid fin system within the Themis program. These are the GFAM (Grid Fin Actuation Mechanism), which acts as the main mechanical structure, and the LLD-D (Latch Locking Device – Deployed), which allows the fins to be locked and unlocked after deployment. Both components will be tested as part of the qualification model.

Meanwhile, the Sener team in Spain is developing the GFAD (Grid Fin Actuation Device), a linear actuator responsible for transmitting motion to the GFAM developed in Poland. Both devices, the GFAD and GFAM, are integral parts of the GFS (Grid Fin System). This system provides the precise control necessary for the safe vertical landing of the Themis first stage.

"Participation in the Themis project confirms Sener's expertise, which is among those creating the most advanced technologies for the European space sector. Sener components will be an integral part of a system that could define the future of European reusable rockets. We are proud to contribute to such a pioneering project," says Jakub Pierzchańa, Director of Sener in Poland.

Themis is designed to demonstrate that Europe can compete with world leaders in reusable rockets. This project could pave the way for cheaper access to space and increase Europe's competitiveness in the global market.
