HyImpulse, a German manufacturer and system provider of commercial launch vehicles for satellite transport, successfully test-launched their 12 meter long and 2.5 ton single-stage rocket “SR75” that can transport smallsats weighing up to 250 kg to an altitude of around 250 km.
The hybrid rocket propulsion system of the launch vehicle operated as planned. After the successful lift-off, the SR75 will be retrieved for further examination and analysis of the data.
HyImpulse introduces a groundbreaking propulsion concept with its rockets, using solid paraffin (commonly known as candle wax) and liquid oxygen as fuel. Paraffin, being both cost-effective and inherently safe as a fuel, serves as an alternative to conventional liquid or solid fuels and does not have the risk to explode. This innovative design significantly simplifies the construction of launch vehicles, cutting costs by a remarkable 40 percent compared to traditional propulsion systems. As a result, satellite transportation expenses are reduced by an impressive 50 percent, demonstrating HyImpulse’s commitment to affordable access to space.
The SL1 multi-stage orbital launch vehicle, scheduled for its inaugural lift-off by the end of 2025, stands at a height of 32 meters and weighs 50 tons. Depending on the weight of the payload, it can ascend to an altitude exceeding 500 km, i.e., reaching low Earth orbits. Designed for cost-effective transportation of smallsats into space, it can carry payloads of up to 600 kilograms to LEO.
Dr. Mario Kobald, co-founder and co-CEO of HyImpulse, said, “ Setting up a commercial launch vehicle equipped with entirely new propulsion technology up for launch and lift-off with such an efficient team and a relatively small budget is quite a feat. We’re signaling Germany’s prowess as a spacefaring nation and expanding Europe’s access to space. Already, we’re planning the launch of a larger, multi-stage transport launch vehicle capable of deploying satellites weighing up to 600 kilograms into low Earth orbits by the end of next year.”
Dr. Christian Schmierer, co-founder and co-CEO of HyImpulse, said, “With this successful launch, which also provides us with valuable data for further development, we have validated our technical concept and demonstrated our market readiness. Our utilization concept is designed for the cost-effective transport of small satellites into space. This enables the implementation of privately funded environmental and climate projects, research projects, as well as navigation, telecommunications, and more. The demand for commercial launch vehicles for the transportation of satellites in Europe is substantial. Accordingly, with a volume well exceeding 100 million Euro, our order book is already substantial and continues to grow monthly.”
