Gilmour Space Technologies has taken another big step toward its first orbital launch with chief executive officer Adam Gilmour expected on Wednesday to announce that the company had been given final approvals for its maiden test-flight. The company is understood to have been given a green light from the Civil Aviation Safety Authority (CASA) to launch the first test flight of its three-stage Eris rocket from its Bowen Orbital Spaceport facility at Abbot Point in Queensland. The approval mean that Gilmour can give the Australian Space Agency and CASA formal notification of its intention to fly, which would open a launch window some time in the back half of March for a launch. Mr Gilmour will present details of the regulatory position to the Australian Defence Magazine Space Summit in Canberra on Wednesday morning, where he is expected to make public its provisional launch plans.
