Europe’s first reusable rocket main stage demonstrator – Themis – being transported to its launch pad at Esrange Space Centre, Sweden.
Themis encompasses all the elements for a reusable rocket stage. The Themis programme includes developing the flight test model that requires new technologies from European countries such as the vehicle landing legs, grid-fin aerodynamic stabilisers, light-weight fuel tanks, distributed power systems, avionics and reduced-diameter multi-engine bay. New flight algorithms, derived from previous European projects, will be key to make Themis land safely after flight.
Themis was developed as a European Space Agency future launchers preparatory programme with ArianeGroup as prime contractor and multiple European industrial partners. Themis’s first flight campaign is being funded by the European Commission Salto programme.
