Australian company Gilmour Space is targeting the middle of March for the first flight of its Eris rocket, while setting expectations for the vehicle’s debut.

Gilmour Space announced Feb. 24 that the launch window for the first launch of Eris, called TestFlight 1, will open March 15 from the company’s launch site, Bowen Orbital Spaceport in northern Queensland. The announcement came after the company finalized airspace arrangements with Australian aviation regulators.

If successful, though, Eris would be the first rocket built in Australia to reach orbit, and the first orbital launch from Australia since the British-built Black Arrow rocket launched the Prospero satellite from Woomera in South Australia in October 1971.

TestFlight 1 is primarily intended to collect data on Eris and its systems ahead of future commercial launches. The three-stage vehicle, using hybrid propulsion, is designed to place up to 215 kilograms into sun-synchronous orbit in its Block 1 iteration. The rocket will carry a test payload for a line of small satellites Gilmour Space is also developing.
