The Ausroc III Program is one of the most advanced initiatives of its type in the world. It is by
far the most ambitious high technology education and development program ever undertaken in
Australia. The methods by which the Program is being advanced are revolutionary. The vehicle
being developed is an order of magnitude more sophisticated than any other rocket previously
developed in this country. From humble beginnings, the Ausroc Program is maturing into a
pathfinder for the re-entry of Australia into the global space industry.
Advancement of the Ausroc Program relies upon the continuing support of government,
industry and the Australian public generally.

The Ausroc III vehicle is a liquid fuelled sounding rocket designed to launch a 150 kilogram payload module to an altitude of 500 kilometres on a sub-orbital trajectory. Unlike most sounding rockets in commercial use today, the vehicle will incorporate active guidance which means that its trajectory will be controllable during flight. The payload module will achieve approximately 6 minutes of weightlessness before re-entry and recovery via a steerable gliding parachute recovery system. These capabilities compare favourably with those of sounding rockets in commercial use today.
