ArianeGroup has successfully carried out the first ignition campaign of the reusable Prometheus® engine on the reusable Themis rocket core stage demonstrator – a key step in providing Europe with the essential technological building blocks for future reusable launchers.
Themis and Prometheus® are central to Europe’s strategy for preparing its future launchers. Both are European Space Agency (ESA) programs for which ArianeGroup is the lead contractor.
This test of a complete rocket stage running on liquid oxygen and bio-methane is a first in Europe.
