A second commercial rocket launch is now scheduled for SaxaVord Spaceport in Shetland, marking another step toward establishing the UK as a key player in the burgeoning private space industry. German firm HyImpulse Technologies GmbH (HyImpulse) announced its plans to conduct a flight with its SR75 suborbital launch vehicle, building on the success of a previous launch in Australia earlier this year.
Expanding European Space Access
HyImpulse joins Rocket Factory Augsburg (RFA) in preparing to utilize SaxaVord Spaceport, located on the remote island of Unst, Shetland, as a commercial launch site. RFA is slated to be the first company to launch from the site, with testing anticipated for the summer. The presence of multiple firms underscores growing interest in Shetland as a prime location for space launches, offering unique advantages for suborbital missions.
What is Suborbital Flight?
The SR75 rocket is designed for suborbital flights – meaning it reaches the edge of space but does not deploy satellites into orbit. This type of mission serves a niche but vital market: researchers and businesses seeking short-duration microgravity experiments or atmospheric studies. The rocket can carry payloads of up to 250kg (550lbs) and is designed for full recovery via parachute after flight.
New Propulsion Technology
HyImpulse is pioneering a novel propulsion system using paraffin wax as solid fuel, combined with liquid oxygen. This hybrid approach, according to co-founder Dr. Christian Schmierer, offers enhanced safety: “We’re developing a completely new propulsion system… a hybrid rocket which cannot explode.” The Shetland launch will serve as a crucial demonstration of this technology’s viability in European conditions.
Implications for the UK Space Sector
The rapid development of SaxaVord Spaceport and the influx of commercial launch providers signal the UK’s ambition to become a competitive hub in the space industry. While suborbital flights are not the same as full orbital launches, they represent a critical early step in building infrastructure, expertise, and regulatory frameworks. This growth could attract further investment, create high-skill jobs, and position the UK at the forefront of space-based research and commercial applications.
HyImpulse’s launch later this year will further validate Shetland’s potential, attracting additional companies and solidifying the UK’s role in the new commercial space race.
