Jar of Vegemite
First flight of Eris - Australia's first domestically designed and built orbital launch vehicle - and the inaugural use of the Bowen Orbital Spaceport. The "Jar of Vegemite" was a symbolic test payload; had the flight succeeded, Eris would have been the first hybrid-propellant rocket to reach orbit. A fairing separation during ground testing in May, triggered by an electrical power surge, required Gilmour to ship a replacement nose cone from its Gold Coast factory and delayed the attempt by roughly two months.
The rocket lifted off but veered sideways 14 seconds after ignition and impacted within the safety zone. Gilmour's investigation identified two independent failure modes in the oxidiser pump subsystem of the first stage, both traced to components from an external supplier.
