SpIRIT satellite booked for launch in early 2023

The Australian-designed SpIRIT satellite, the first selected for funding by the Australias Space Agency, has been booked with launch service provider ISISPACE to blast off on the Falcon 9 Transporter 8 rocket in April 2023.

The Space Industry Responsive Intelligent Thermal (SpIRIT in short) is a small, shoebox-sized nanosatellite (just 30cm) during launch, but once in orbit it will deploy solar panels and thermal radiators stretching to nearly a meter long.

It will run a suite of scientific instruments, cameras, guidance systems, communication antennae, on-board computers with artificial intelligence capabilities, and even its own electric propulsion thruster.

The spacecraft is being designed and built by a consortium led by the Melbourne Space Laboratory at the University of Melbourne, with participation from Australian industry partners and the Italian Space Agency. It will operate in orbit for two years demonstrating the long-term performance of Australian-made space technology.

Principal Investigator Professor Michele Trenti from the School of Physics at the University of Melbourne said the signing of the launch contract was a critical milestone, which reflects the strong progress towards readiness for flight.

“The team has got to this point less than two years since selection of the mission for funding,” Professor Trenti said. “This demonstrates how a nanosatellite project can successfully combine best practices in project management and systems engineering, traditionally the preserve of larger missions, with the innate agility of a nanosatellite project.”

At only 11.5 kg, SpIRIT is too small to fly on a rocket on its own, so the team booked a rideshare service through ISISPACE, one of the world’s most experienced launch service providers. ISISPACE will package SpIRIT in a canister and integrate it into a ring hosting dozens of other small satellites, and then deliver the package to the US-based launch pad for a short ride to Low Earth Orbit (LEO), about 550 km above the earth.

The Australian Space Agency is injecting almost $4 million into this space science mission through its International Space Investment Initiative. Australian Space Agency Head, Enrico Palermo said it was terrific to see such an important milestone reached.

“The pace at which progress is being made on SpIRIT is testament to the knowledge and skill that exists in the Australian space sector and what can be achieved when we collaborate with our international partners. I thank our partners at the Italian Space Agency, ASI for their contributions to this project,” Mr Palermo said.

In addition to the University of Melbourne, Sitael Australia, Inovor Technologies and Neumann Space are contributing to the innovative design and fabrication of SpIRIT, with Nova Systems providing ground station support from the Nova Space Precinct.

The main scientific instrument of the mission, contributed by the Italian Space Agency, is an advanced X-ray detector to discover gamma rays emitted some of the Universe’s most powerful explosions.

Once in orbit, SpIRIT will commence its mission to demonstrate multiple made-in-Australia technological innovations, including the first flight of Inovor Technologies’ Apogee satellite platform and of the Neumann Space thruster.
