The two-stage launch vehicle Spectrum

ESA has signed the first three contracts with European economic operators arising from its permanently open call for proposals for commercial space transportation services.

Boost! – ESA’s Commercial Space Transportation Services and support to Member States programme was adopted at Space19+ and an Open call for proposals under its Element 1 was launched in April this year. Through this programme, ESA aims to stimulate and support competitiveness and new commercial European space transportation services.

ESA provides co-funding, expert advice and the use of testing facilities that help entrepreneurs to take their service projects towards commercialisation.

On November 11, the first Boost! support contracts have been signed with three German New Space companies: HyImpulse Technologies, Isar Aerospace Technologies, and Rocket Factory Augsburg.

All three companies are preparing to offer new launch services using small launch vehicles to serve the growing small satellite market.

“It is great to see this high level of entrepreneurship in Germany, targeting new commercial launch services for small payloads. Boost! offers tailored support at the pre-commercial phase to help these companies to succeed with their business and technical objectives,” explained Thilo Kranz, ESA’s Commercial Space Transportation Programme Manager.

The launch vehicle SL1

HyImpulse Technologies, based in Neuenstadt am Kocher in Southern Germany is developing a three-stage small launcher. The launch vehicle, called SL1, will be powered by green hybrid propulsion technology, using liquid oxygen and paraffin as propellants.

The Boost! contract ‘HyImpulse SL1 Launch Service Development Support’ will help the company to finalise preliminary design solutions and verification plans for all key systems of the launch system and support the development of associated ground support equipment, including for critical subsystem testing.

The two-stage launch vehicle Spectrum

Munich based Isar Aerospace Technologies, initially supported by ESA’s Business Incubation Centre Bavaria, is developing a two-stage launch vehicle called Spectrum to serve the small satellite market.

The ‘Spectrum Launch Service Development Support’ contract will cover measures to advance the rocket’s ‘Reaction Control System’. It will further support the definition and build-up of the launch vehicle manufacturing line at the Isar Aerospace premises in Ottobrunn.

The launch vehicle RFA One

Rocket Factory Augsburg, backed by the German satellite manufacturer OHB and Munich-based venture capital firm Apollo Capital Partners, is developing a three-stage launcher system equipped with an orbital stage. The vehicle called RFA ONE will be using state-of-the-art staged-combustion engine technology for its main propulsion systems.

Under the ‘RFA One Launch Service Development Support’ contract, Rocket Factory Augsburg will receive support with the detailed design, manufacturing as well as testing of its first stage demonstrator.

“We look forward to supporting these companies in achieving their ambitious objectives, fostering diversification and competitiveness of the European space transportation sector,” added Jorgen Bru, ESA’s Commercial Services Manager and technical officer for these contracts.
