Europe's First Reusable Rocket Demonstrator, Themis, Ready for Launch
2025-09-23
The first model of the European Space Agency's (ESA) reusable rocket demonstrator, Themis, is standing tall on its launchpad in Kiruna, Sweden. This 30-meter-tall rocket, featuring the Prometheus engine—nearly as powerful as the Ariane 6's main engine— boasts in-flight restart and thrust throttling capabilities for a safe landing. Themis aims to demonstrate vertical takeoff and landing with cryogenic propulsion, with its maiden flight supported by the Horizon Europe project Salto. This marks a significant step forward for Europe in reusable rocket technology.
