ORBITAL WHISPERS

Gilmour Space is Australia’s attempt at having a real launch industry instead of just press conferences with kangaroos in the background. They’ve gone the hard route, build the rocket, build the engines, and, since nobody else bothered, build the launch site too. The hardware is Eris, a three-stage hybrid using solid fuel with hydrogen peroxide oxidizer, theoretically good for 300 kilos to LEO. It’s the kind of design you pick when you don’t have endless budgets for kerosene turbopumps and when “keep it simple” is the only way you’re getting a flight license out of Canberra.
They’ve pulled in north of $140 million in venture funding plus some modest government grants, which in space launch terms is barely enough to cover Elon’s catering budget but in Australia makes you a national champion. The Bowen Orbital Spaceport is their sandbox, an actual pad with permits that puts them ahead of every other would-be southern hemisphere launcher stuck at PowerPoint stage.
The July 2025 maiden flight was classic “first rocket syndrome.” Four hybrid engines lit, the rocket left the pad, climbed for 14 seconds, then lost thrust and pancaked back down. Not an explosion, but not orbit either. Engineers are now writing conference papers about how “we captured valuable data,” which is industry code for “back to the workshop.” The upside is they proved the pad works, the engines ignite, and regulators didn’t yank their license on day one.
Strategically, Gilmour is aiming for the small-sat and defense niches. Not mass-market, not rideshare, but sovereign access and dedicated launches for payloads that don’t want to be crammed next to SpaceX’s broadband spam. They’re also well-positioned for hypersonic test contracts, the Australian Department of Defence has quietly been bankrolling this ecosystem because they don’t love relying on the US for every flight test.
The challenge is sustainability. Even with sovereign cheerleading, the economics of a 300-kg launcher are brutal. If Eris doesn’t become reliable fast, the whole thing risks being an expensive flag-waving exercise. On the other hand, if they can rack up a few flights and carve out a defense-heavy customer base, they’ll become exactly what Canberra wants: a locally-owned, semi-independent launch capability with a side business in smallsat commercial missions.
Short version: Gilmour is trying to be Rocket Lab without leaving Australia. First flight went down in flames, literally, but they’ve still done more hardware, funding, and permitting than any other Australian launch hopeful. Whether they grow into a viable player or just a sovereign vanity project depends entirely on how quickly flight two gets off the pad and how many satellites Canberra is willing to pay them to throw skyward.
