UniSQ and DLR Successfully Complete GAsFEx-2 Hypersonic Flight Test

UniSQ and DLR Successfully Execute GAsFEx-2 Hypersonic Mission

In a significant stride for international aerospace collaboration, the University of Southern Queensland (UniSQ) has successfully completed its second hypersonic flight experiment, known as GAsFEx-2 (Germany Australia Flight Experiment II). Launched on November 12, 2025, from the Esrange Space Center in Sweden, the mission utilized the German Aerospace Center’s (DLR) MAPHEUS-16 sounding rocket. This event marks a pivotal moment for the iLAuNCH Trailblazer program, demonstrating the viability of cost-effective flight testing for hypersonic technologies.

The mission saw the payload ascend to an altitude of approximately 267 kilometers, reaching well into the thermosphere. During the 14-minute flight, the experiment experienced over six minutes of microgravity, providing a pristine environment for data collection. This launch was not merely a repetition of previous efforts but a sophisticated evolution, designed to test advanced avionics and gather critical aerothermodynamic data under real-world hypersonic conditions. The success of this operation underscores the growing capability of Australian institutions to lead complex, multi-national space missions.

At the heart of this achievement is the strategic shift toward a “ride-along” operational model. By integrating the GAsFEx-2 payload into a rocket primarily tasked with materials physics research, the team effectively bypassed the prohibitive costs associated with dedicated hypersonic launches. This approach aligns with the broader goals of the iLAuNCH Trailblazer initiative, which aims to accelerate the commercialization of space research and foster a sovereign space manufacturing sector in Australia.

The “Ride-Along” Model: Reducing Costs and Barriers

One of the most substantial hurdles in hypersonic research has always been the astronomical cost of flight testing. Traditionally, validating technology at speeds exceeding Mach 5 requires booking an entire launch vehicle, a financial burden that often stifles innovation for startups and universities. The GAsFEx-2 mission challenges this paradigm by proving that high-value hypersonic experiments can successfully “hitch a ride” on existing launches. According to project data, this rideshare approach can reduce testing costs by up to 95 percent compared to standalone campaigns.

The technical execution of this model required precise engineering. The GAsFEx-2 experiment was one of 21 different payloads aboard the MAPHEUS-16 rocket. It was integrated specifically into the nosecone to measure temperature and flight conditions during the high-speed ascent without interfering with the primary scientific payloads. This successful integration demonstrates a scalable pathway for frequent, affordable access to hypersonic environments, allowing researchers to iterate designs much faster than previously possible.

We see this mission as a validation of the “flight heritage” concept. For emerging aerospace companies, proving that components function in the harsh environment of space is a prerequisite for commercial adoption. By lowering the barrier to entry, the ride-along model allows entities like HyperFlight Systems to gain this crucial flight heritage without the need for massive capital investment in launch infrastructure.

“This successful flight is a key step toward making hypersonic flight testing more accessible, affordable, and reliable. By demonstrating our ability to design, manufacture and fly ride-along hypersonic payloads, we’re opening new opportunities for industry and academia.”, Professor Ingo Jahn, UniSQ Project Lead.

Strategic Partnerships and Technical Validation

The GAsFEx-2 mission was a complex orchestration of international expertise. While UniSQ led the project and experiment design, the execution relied heavily on the capabilities of the German Aerospace Center (DLR). DLR’s Mobile Rocket Base (MORABA) managed the launch operations, utilizing the MAPHEUS-16 vehicle powered by two “Red Kite” solid rocket motors. This configuration allowed the rocket to carry a record payload mass of 500 kilograms, facilitating the inclusion of multiple experiments.

A critical component of the mission was the involvement of HyperFlight Systems, a Queensland-based aerospace startup established in 2022. The mission provided a platform to test their next-generation avionics hardware and data acquisition systems. Obtaining data from a real hypersonic flight is invaluable; it moves technology from a theoretical Readiness Level (TRL) to a proven status. The avionics monitored the vehicle’s performance, ensuring that the data collected was accurate and retrievable.

Furthermore, the collaboration extended to the Technical University of Munich (TUM), which partnered on simulation and numerical monitoring. This relationship creates a vital feedback loop. The real-world data harvested from the flight is used to validate computer simulations and ground-based tests conducted at UniSQ’s TUSQ hypersonic wind tunnel. This “closing of the loop” ensures that future digital models are more accurate, reducing the risk for subsequent physical tests.

“This collaboration provides a platform for us to prove new avionics designs in a relevant hypersonic environment. Working alongside UniSQ and international partners strengthens Australia’s aerospace capability by building local expertise in hypersonic flight systems.”, Robert Pietsch, Principal Engineer at HyperFlight Systems.

Future Implications for the Aerospace Industry

The successful recovery of the payload and the data it contains signals a shift from pure research to commercial application. The ability to retrieve the experiment intact allows for post-flight analysis of thermal protection systems and structural integrity. This is particularly relevant for the development of reusable hypersonic vehicles, a sector that is garnering significant global attention. The improved recovery mechanisms tested during this mission ensure that sensitive instruments can be reused, further driving down costs.

Looking at the broader picture, the iLAuNCH Trailblazer program’s $180 million investment is beginning to yield tangible results. By linking academic research with industry needs, the program is cultivating a workforce skilled in advanced manufacturing and avionics. The GAsFEx-2 mission serves as a case study for how government-backed initiatives can facilitate international cooperation that benefits local industry. It positions Australian companies not just as participants, but as competent partners in the global space economy.

As we look toward the future, the frequency of these tests is expected to increase. The standardization of the ride-along interface means that future MAPHEUS launches could routinely carry Australian hypersonic experiments. This regularity is essential for rapid prototyping cycles, allowing engineers to test, fail, fix, and fly again within months rather than years. It is a methodology that accelerates innovation and ensures that safety and reliability standards keep pace with technological advancements.

Concluding Section

The GAsFEx-2 mission represents more than just a successful rocket launch; it illustrates a sustainable model for the future of hypersonic research. By leveraging international partnerships and utilizing excess capacity on sounding rockets, UniSQ and its partners have demonstrated a pathway to reduce the financial and logistical barriers that have long hindered the sector. The data gathered from the thermosphere will now feed back into laboratories in Queensland and Munich, refining the models that will design the next generation of aerospace vehicles.

As the global demand for faster, more reliable space access grows, the ability to conduct frequent and affordable flight testing will be a decisive competitive advantage. Through the iLAuNCH Trailblazer program, Australia is securing its foothold in this high-tech domain, proving that with the right collaboration, the sky is no longer the limit.
