Australia's first satellite was called WRESAT

Australia's first satellite was called WRESAT, which stands for Weapons Research Establishment Satellite. It was designed and built in Australia by the Weapons Research Establishment (WRE) in Salisbury, South Australia, in collaboration with the University of Adelaide, the University of Melbourne, and the Department of Supply.

WRESAT was launched into orbit on November 29, 1967, from the Woomera Rocket Range in South Australia. It was the first satellite launched from an Australian facility and also the first satellite launched by a British or Commonwealth team.

WRESAT was a small satellite, weighing just 45 kilograms and measuring 66 centimeters in diameter. Its primary mission was to test the feasibility of using rockets to launch payloads into space from Australia. It also carried several scientific experiments to measure atmospheric density and other environmental factors.

The satellite remained in orbit for 42 days before re-entering the Earth's atmosphere and burning up upon re-entry. Although it had a relatively short lifespan, WRESAT was a significant achievement for Australia, demonstrating the country's capability to design, build, and launch its own satellite.
