Gilmour Space Technologies launched the Eris TestFlight1 rocket from the Bowen Orbital Spaceport in Queensland on July 30, 2025.
The Eris TestFlight1 rocket came down in the designated safety area about 14 seconds after liftoff.
Gilmour Space Technologies said its next Eris rocket test is still planned for later in 2025.
Gilmour Space Technologies concluded that electrical and thermal faults in the oxidizer pump system of two first-stage motors caused the loss of the Eris TestFlight1 rocket.
The Eris rocket is 25 meters tall and roughly 30 metric tons in mass.
One of the four first-stage hybrid rocket motors on Eris TestFlight1 lost thrust about nine seconds after ignition.
A second first-stage hybrid rocket motor on Eris TestFlight1 lost thrust at around 17 seconds after ignition.
Gilmour Space Technologies submitted a final report on the Eris TestFlight1 investigation to the Australian Space Agency in coordination with the Office of the Space Regulator.
The Eris rocket lost control and came down within the designated safety area about 14 seconds after liftoff.
The Eris rocket is designed to deliver up to 215 kilograms of payload to sun-synchronous orbit.
Gilmour Space Technologies concluded that electrical and thermal faults in the oxidizer pump system of two first-stage motors caused the loss of Eris TestFlight1.
Eris TestFlight1 was the first orbital launch attempt by Australia in more than 50 years.
The Eris rocket lifted off from the Bowen Orbital Spaceport near Bowen, Queensland, on July 30, 2025.
Gilmour Space Technologies completed its investigation into the July 2025 in-flight failure of Eris TestFlight1.
Electrical and thermal faults were observed in the electric pump motors and associated inverters on Eris TestFlight1, including components sourced from an external supplier.
Eris TestFlight1 lifted off from the Bowen Orbital Spaceport on 30 July 2025.
About nine seconds after ignition, one of Eris TestFlight1’s four first-stage hybrid rocket motors experienced a loss of thrust.
Gilmour Space has concluded its investigation into the maiden flight of Eris TestFlight1, Australia’s first orbital rocket.
