On the basis of the cutting-edge and concept-proofed beam-steerable antenna invented by the team, this project aims at tackling the system-level challenges and developing a commercial-ready millimeter-wave satellite terminal to deal with the digital inequality facing rural and remote Australia. The proposed terminal can lead to a household-affordable price system that is compact and can be installed on a fixed/mobile platform for broadband connectivity. The project will have an immediate socio-economic impact for families and small businesses located in rural areas in Australia that have poor digital access, meanwhile, it has great potential to transform the local industry partner' business into a highly profitable emerging market.Read moreRead less

A Space-Based Quantum Communications Platform using Continuous Variables. This work proposes to investigate a new space-borne platform capable of quantum communications with a terrestrial ground station. Different from existing space-borne quantum communication platforms, our new platform will be based on CV (Continuous Variable) technology and will integrate the ability to seamlessly switch to classical Free-Space Optical communications when channel conditions deem quantum communications are too difficult. Currently no quantum satellite built on CV technology exists. Our research will produce a significant advance in an emerging technology space, and will allow Australia to take scientific leadership in an important aspect of ultra-secure communications from satellites.

This project aims is to study the non-equilibrium aerodynamic processes involved in hypervelocity flight. The design of vehicles for high speed flight is critically dependent on modelling the interactions between the flow field and the airframe, and the current lack of understanding is restricting the scope and benefit of viable activities in space. The expected outcomes include the ability to design optimised heat shields and air-frames with minimum mass and maximum payload, precisely targeting specific flight conditions and vehicle shapes. The prospective benefits include increased productivity and reliability and reduced cost of missions to and from space, and a proliferation of new applications which this understanding will facilitate.Read moreRead less

This project aims to improve models used to design the heat shields which protect probes entering the atmospheres of the giant planets - four gaseous planets out beyond Mars. Further giant planet exploration is a key planetary science goal of the coming decade. However, the environment which an entry probe would experience features many unknowns and large uncertainties, making a mission a risky undertaking. Using unique experimental capabilities and state-of-the-art modelling, the expected project outcome is experimentally validated giant planet entry flow and surface chemistry models. This will allow more efficient heat shields to be designed while also increasing the chance of mission success, furthering our understanding of the universe.Read moreRead less

Beyond Apollo: The interaction of radiation and ablation during Mars return. This project aims to investigate how flow radiation and heat shield ablation products interact under the fastest hypersonic Earth entry conditions ever considered – Mars return. To survive the harsh conditions experienced during planetary entry, spacecraft rely on ablative heat shields burning away through processes which are still not fully understood.

This project aims to investigate how flow radiation and heat shield ablation products interact under the fastest hypersonic Earth entry conditions ever considered – Mars return. To survive the harsh conditions experienced during planetary entry, spacecraft rely on ablative heat shields burning away through processes which are still not fully understood. Using UQ’s unique X2 hypersonic wind tunnel to generate realistic flight conditions, the expected outcome of this project is an enhanced understanding of the complex ablation radiation coupling physics experienced during Mars return. This will bring humankind closer to travelling to and from Mars and increase our knowledge of these entries and the specialist materials needed to survive them.Read moreRead less

A spaceship returning from Mars will undergo unprecedented aerodynamic heating as it enters Earth's atmosphere. Magnetohydroynamic aerobraking involves applying a strong magnetic field to the plasma which forms around the spacecraft at these speeds, theoretically protecting it by reducing structural heat loads and enabling less severe flight trajectories. This project aims to experimentally study this technology for Earth return from deep space.
