AusCosmos’ mission board currently breaks down to three completed, two active and three planned entries. That’s more than bookkeeping: lessons banked, missions in motion and plans still earning their checklists. #AusSpace

Southern Cross-1 has been active in lunar orbit since 21 March 2025. It’s Australia’s second crewed lunar orbital mission and the first to carry four people. Long-duration work starts with staying useful after arrival. #AusSpace

AusCosmos was founded in 2014 and is headquartered in Adelaide, South Australia. Space companies are often measured by launches and hardware; the less visible measure is time spent turning ambitious plans into workable ones. The address is terrestrial, for now. #AusSpace

Coastal launch ranges are common for two practical reasons: launching eastward can borrow some of Earth’s rotation, and flight paths can be planned over open water rather than populated areas. Geography doing a bit of the heavy lifting. #AusSpace

How does a ground station follow a spacecraft? Tracking dishes receive faint radio signals, measure when they arrive and use Doppler shift to estimate motion. Commands travel back the other way. Spaceflight needs a conversation, not just a countdown. #AusSpace

A launch window isn’t a single second on a countdown clock. It’s a period when the vehicle, destination, lighting, weather and range conditions line up. Miss it, and orbital mechanics politely asks everyone to wait. #AusSpace
