The rocket SR75 from HyImpulse has been fully prepared and packaged in time at the HyImpulse headquarters in Neuenstadt, Germany. Both the rocket and its ground support equipment have started the journey by ship through the Atlantic Ocean, around South Africa, and all the way to Southern Australia.
The Koonibba test range will be the final destination for the fully fuelled, but non-explosive rocket. The launch campaign is scheduled to commence from mid-April at the Koonibba test range which is operated by Southern Launch.
The key highlight of the SR75 rocket is its innovative hybrid rocket engine based on solid paraffin – a non-explosive fuel that revolutionizes rocket handling and logistics. This allows the SR75 to be fully loaded with fuel during the whole transport. There are no explosive materials involved which reduces logistical complexities significantly and always ensures the readiness and safety of rocket launches. This enables HyImpulse to pre-produce, store, and transport rockets more efficiently and safely. This unique approach simplifies also the shipping and custom processes, setting a new standard in the space industry, resulting in overall much lower costs.


The hybrid propulsion system from HyImpulse is set apart by its high performance, its simplicity, and its scalability in manufacturing, which drastically lowers costs. This unique approach to scale-up of commercial launch services is made possible through the specialized HyImpulse paraffin fuel formulation and pioneering motor design. Looking towards the future, HyImpulse is committed to achieving carbon-neutral operations, driven by our use of a synthesized paraffin fuel derived from captured CO2 and renewable energy sources. The unique and environmentally friendly rocket motor has been demonstrated successfully by many ground test firings on the ground at the HyImpulse test facility on Shetland Islands. All tests were completed with the representative flight configurations of the motor.
In parallel to the SR75 flight activities, the development of the SL1 orbital launcher, with ten clustered SR75 motors, is progressing well. Relationships are being established with potential subsystem suppliers i.e. structures and electronics, with HyImpulse retaining full control of the propulsion system, the trademark of HyImpulse. At the same time, HyImpulse acts as a system integrator for other subsystems that can be acquired commercially and very effectively from space and non-space industries. This approach reduces capital expenditure and ensures that subsystems using the latest technologies can be acquired in a competitive and timely manner from world-class providers.
