  • Goal mission price max. 2,5 million Euro (excl. tax and insurance)
  • Partially reusable concept
  • Transportable inside a single standard 40’ container
  • Storable propellants –> extensive use of composites
  • Engine out capability
  • Booster landing on a mobile platform
    • Landing flexibility –> enhanced capacity
    • Booster mass saving
    • Effective and prompt Booster securing and pick up
  • Robust and user friendly propulsion system
  • Pressurization gas as the RCS propellant
  • Fairing is an integral part of the Booster
    • Nothing falls off during ascent –> enhanced ground safety
