Themis is an ESA rocket prototype – a flagship European demonstrator for low-cost rocket recovery and reuse technologies. Powered by the reusable, methane-fuelled engine Prometheus, it is developed with ArianeGroup as prime contractor and building on decades of European research and experience in rocketry and space operations, Themis is designed to launch, land vertically and live on for another mission.
