Bowen Orbital Spaceport is Australia's first licensed orbital launch facility, owned and operated by Gilmour Space.​ ​​
✔ Access to low- to mid-inclination orbits​
✔ Site of Australia's first sovereign orbital launch attempt, July 2025​
✔ Supporting future launch cadence
✔ Partnering with the QLD Government, Juru people of Bowen, and Bowen community​
Launch vehicle + satellite platform + licensed spaceport = simplified mission planning.
MILESTONES TO ORBIT
Global demand for satellite launches continues to grow, but access to suitable orbits remains highly constrained.​​
Gilmour Space is building an end-to-end launch capability designed to simplify mission planning, improve operational flexibility, support launch cadence, and provide affordable and reliable access to orbit from Australia.​​​
