SR75 is HyImpulse’s single-stage suborbital rocket for microgravity research, atmospheric observations and technology demonstrations. Its hybrid propulsion uses paraffin and liquid oxygen. HyImpulse records a first test launch from Koonibba, South Australia, on 3 May 2024 and offers the design for suborbital launch services. Published payload and altitude claims vary across its pages, so no single capacity is asserted here.
