The Themis programme is an ongoing European Space Agency programme that is developing a prototype reusable rocket first stage and plans to conduct demonstration flights. The prototype rocket will also be called Themis.
Themis is expected to provide valuable information on the economic value of reusability for the European government space program and develop technologies for potential use on future European launch vehicles.[1][non-primary source needed]
Themis will be powered by the ESA's Prometheus rocket engine.[1]
Two possible landing sites have been mentioned in discussions surrounding the project:[2]
The estimated program timeline, as of December 2020[update], is as follows:[4]
Suborbital flight tests were slated to begin as early as 2023 at Europe's Spaceport in Kourou, French Guiana, but have been delayed.[2]
Eventually, lessons learned with Themis' development will pave the way for developing the European reusable launcher Ariane Next, which should first fly in the 2030s.[6]
On 15 December 2020, ESA signed a contract worth €33 million with prime contractor ArianeGroup in France for the ‘Themis Initial Phase’. This first phase of the Themis programme involves development of the flight vehicle technologies and test bench and static fire demonstrations in Vernon, France. It also includes the preparation of the ground segment[clarification needed] at the Esrange Space CenterinKiruna, Sweden, for the first hop tests and any associated flight vehicle modifications.[2][non-primary source needed]
On 22 June 2023, the first hot-fire test of the Prometheus engine, as a part of the Themis first stage demonstrator, was successfully conducted in Vernon, France.[7]
