Australia Rocket launch Set for Today by Gilmour Space Technologies

Technology

Australia is set to make space history today. For the first time, a fully Australian-built rocket is preparing to launch into orbit. The mission, called TestFlight 1, will lift off from the Bowen Orbital Spaceport in Queensland. It’s a big moment not just for science, but for Australia’s future in space. This rocket launch from Australia is about showing the world that they, as a nation, can build and launch their space tech.

The company behind this bold mission is Gilmour Space Technologies, a homegrown startup that started small but dreamed big. Now, they’re about to become the first private firm in Australia to attempt a full orbital launch.

Let’s explore what makes this mission special, how the rocket works, why the launch matters, and what’s next for Australia’s space goals. 

Background on Gilmour Space

We saw Gilmour Space grow from a small startup into a key player in Australia’s space story. Founded by brothers Adam and James Gilmour around 2015, the company developed its hybrid rocket engine and the Eris launch vehicle from scratch. They built a manufacturing campus in Yatala and earned funding and regulatory approval from both CASA and the Australian Space Agency.

Why This Launch Matters?

Gilmour Space becomes the first Australian company to receive an orbital launch license,
Gilmour Space becomes the first Australian company to receive an orbital launch license, marking a major milestone for the nation’s space industry.

This mission could change everything. Eris TestFlight 1 will be the first fully Australian‑designed and built rocket to attempt orbit from our soil. Australia did launch a satellite back in 1967, but that used a U.S. rocket. This time, the rocket is truly theirs. A success here puts Australia in a select group; only a handful of nations have sovereign launch capability. They could even start space tourism from Bowen, which analysts call “Australia’s Cape Canaveral”.

The Eris Rocket: Specs & Systems

Eris stands about 25 m tall and weighs around 34 t at launch. It is a three-stage rocket. The first two stages use Sirius hybrid engines: a solid fuel grain plus hydrogen peroxide oxidizer. The first stage has four engines. The second stage uses one. The third stage uses a liquid‑fuel Phoenix engine.

Eris can lift about 215 kg into sun‑synchronous orbit. It can carry up to 305 kg to low‑inclination orbits. Its fairing is about 1.5 m wider than some competitors’.

Launch Site – Bowen Orbital Spaceport

They will launch from Bowen Orbital Spaceport at Abbot Point, in North Queensland. This is the country’s first licensed commercial orbital launch site, built and run by Gilmour Space. Its location lets Eris ride Earth’s spin for equatorial orbits between 20° and 65° inclination. The site opened officially in April 2025 after working with the Juru traditional landowners.

Launch History & Delays

We watched several launch windows slip by. The first was set for mid‑March 2025, then moved to May 15. That attempt was scrubbed because of an electrical anomaly in the rocket’s systems. The payload fairing triggered early on the pad, not a bird, as a rumor claimed, but a technical fault. A new fairing was sent from the factory. A second attempt cleared the pad but had to pause due to high winds and scheduling issues.

 exact launch date and time for Gilmour Space’s Eris TestFlight 1
Gilmour Space has delayed its historic rocket launch due to weather and technical checks. The exact launch date and time for Gilmour Space’s Eris TestFlight 1 is Tuesday, July 29, 2025, at 3:30 AM UTC. In local Queensland time (AEST), that corresponds to approximately 2:00 PM on July 29, 2025.

Most recently, Gilmour pushed the launch to no earlier than July 27 to allow more testing and rest for the team. They then revised to July 28-29, weather permitting.

Objectives & Expectations

We understand that TestFlight 1 is a test. The company says that just getting off the pad, passing max‑Q, or releasing its payload will count as success. What matters is learning. Every second of flight gives data to help future missions. They expect checks on staging systems, engine performance, flight path control, and avionics software.

Payload and Symbolism

Eris will carry small commercial and research satellites. It will also carry a jar of Vegemite, an Australian symbol to show national pride and add a fun touch to the flight. It shows how Australia is tying space innovation to national identity.

Challenges Ahead

We know maiden flights are tough. Hybrid rocket engines are a bold technology. The weather in coastal Queensland is unpredictable. Regulatory checks from CASA and Airservices Australia add complexity. Public expectations are high, but realism is key.

Industry & Regional Context

X Source: Strategic Updates for Australia’s Space Industry

Australia’s space sector is growing fast. Gilmour involves more than 300 Australian suppliers and employs around 200 staff. Other sites, such as Southern Launch’s Whalers Way and Cape York’s Space Centre Australia, offer broader capabilities in the coming years.

Australia Rocket Launch: What’s Next?

If the launch succeeds, Gilmour will push ahead with commercial Eris missions. They will offer ride-share services and pursue larger payloads. If they have to scrub, they will review data and try again with improvements. Long-term goals include crewed missions and expanding Australian launch infrastructure.

Wrap Up

This launch is more than just a rocket going into space. It’s about proving that Australians can build and fly spacecraft from soil. Gilmour Space’s Eris rocket marks a turning point not just for the company, but for our entire space industry.

Now the world is watching. And they’re ready to rise.

Frequently Asked Questions (FAQs)
