When the University of Southern Queensland (UniSQ) and international partners sought to observe the Hayabusa2 capsule’s fiery return to Earth, they faced a major obstacle: the capsule would only be visible for less than a minute, at over 40 km altitude, above Woomera, South Australia. To succeed, the observation aircraft had to be in the right place, at the right time, with specialised instruments ready to collect usable data.

Most agencies plan such airborne campaigns over 12–18 months. RTI and UniSQ had just eight days to design instruments, prepare the aircraft, install mounts, plan flight paths, and mobilise an international research team. The project required precision planning, technical expertise, and operational agility – capabilities RTI provides as standard.

• Captured high-fidelity spectra of the Hayabusa2 re-entry, with shock-layer radiation corrected for atmospheric effects.

• Measured capsule surface temperatures ranging from 2500–3700 K, including spatial temperature distributions across the heat shield.

• Quantified atomic line emissions (H, N, O) in the shock layer, advancing understanding of dissociation and ionisation processes during hypervelocity entry.

• Delivered datasets that allow direct validation of computational aerothermodynamic models, independent of observer location.

• Demonstrated a rapid-response airborne observation capability, confirming Australia’s sovereign ability to lead space science projects.

RTI delivered aircraft integration, project planning and execution under extreme time pressure, allowing researchers to capture a “once in a decade” dataset on spacecraft re-entry.

For prospective partners, the Hayabusa2 mission demonstrates RTI’s ability to solve complex challenges quickly, reliably and at an international standard.
