“What we do”
Launching Cubesats for and from Australia, April 2017
SAR Formation Flying: Garada • 2011-2013, about $10M • Partners: Astrium, BAE
Systems, Delft/Curtin, General Dynamics
• Three main activities: – Phase A SAR formation
flying system design – L1/ E1/ L5/ E5 GNSS
receiver – GNSS reflectometry
Launching Cubesats for and from Australia, April 2017 7
• The initial constellations considered were cubesats – radar extremely difficult
• GNSS receiver was made in cubesat format
• Reflectometry work led to later cubesat application
Cubesats in Garada?

Research Questions Research Questions Missions Which asteroids to mine? What to mine? (exploration, resource modelling) Optimising trajectories for multiple asteroid missions Fractionated spacecraft/ swarms Infrastructure: Fuel depot / distributions to satellites Which resources are running out: map against which are available via OEM. Rare earth, Indium?
Cost of return: if resources are brought back to earth, how is it done? What vehicles are used? Spacecraft Small propulsion systems for cubesats Ion thrusters powered by photovoltaics Telescopes for prospecting Positioning and Attitude Self organised swarms Use of virtual reality Deep space communications On-board power systems Robotics –automation issues Robotics – on-orbit assembly
Mining Technology How to reach/ descend/ land/ anchor/ excavate/ contain/ examine/ ascend/ return. Drone sensors – on-board processing Drone sensors – data analytics/ decision making Drone sensors – space modifications Asteroid grand challenge – what crowd-sourcing is already happening, how can it be exploited and what else could be done?
Which terrestrial exploration (prospecting) instruments can be modified for use in space? Which terrestrial mining method can be used or modified for OEM? Simulation – modify existing UNSW mine simulators for OEM Rock breakage technologies: Drilling and Blasting; Rock Cutting; Laser Cutting; or Novel techniques Resource Mapping: Geophysics; Sampling; etc. Microgravity geology Space biomining Soil simulants Extracting water from icy soil Energy from mining – creating fuel, making solar cells? In-situ resource utilization (ISRU): 3D printing, sintering Weighing material in space
Environment Clean mining Other uses of resources : waste management, infrastructure Development of critical insights (risk, uncertainty, sensitivity) into OEM wrt environmental/ social/ ethical / religious/ traditional / cultural / colonial / philosophical/ legal/ diplomatic / political/ economic / financial dimensions. Other contexts: earth’s shortages of commodities, employment / skills requirements, the aspirational effect of space, societal feedbacks. What would the impacts be on asteroids and Mars? What are the water needs / How is waste handled/ Should bacteria be used / or nanotech / Is uranium an issue? How would the Earth’s atmosphere be affected by excess traffic (e.g. effects of NOx on ozone layer)? Economics Funding it – venture capital or government? Tax-right-off or royalties? Crowd funding? Supply and demand effects on earth’s markets if returned. Financial and Technical Modelling of the missions Creating a market in space for mined products Law How to rewrite the treaties to allow economic expansion?
