The project will increase the visibility and status of Australian research, by the participation of researchers and students in a wide international collaboration, covering experiments, theory, and computation, which will solve a fundamental research problem that has previously defied understanding. The resulting nitrogen model will be relevant to the important fields of global and planetary atmospheric change, and will find immediate application in the analysis of results from the NASA missions, Voyager, Cassini, and (later) New Horizons. In the experimental part of the project, an Australian-first extreme-ultraviolet laser facility will be developed which will provide research opportunities complementary to the Australian Synchrotron.Read moreRead less
Structural transitions in turbulent fluids and plasma through self-organization. Studies into structural transitions in turbulent systems will greatly benefit Australia through its contributions to the science of complex systems, in the areas of self-organization and turbulence control. Applications range from understanding the formation of the Earth's atmospheric spectrum to generation of transport barriers in magnetically confined plasma, as well as development of novel methods of turbulence c ....Structural transitions in turbulent fluids and plasma through self-organization. Studies into structural transitions in turbulent systems will greatly benefit Australia through its contributions to the science of complex systems, in the areas of self-organization and turbulence control. Applications range from understanding the formation of the Earth's atmospheric spectrum to generation of transport barriers in magnetically confined plasma, as well as development of novel methods of turbulence control in engineering. Recent discoveries by the authors open a window of opportunity for a breakthrough in this fundamental field of modern science. The project is based on several national and international collaborations. Australian postgraduate and research training is an integral part of the project.Read moreRead less
Current-free double layers applied to astrophysical objects and space propulsion. The collaboration between the ANU research group and European Aeronautic Defence and Space Company (EADS) ASTRIUM, the largest European aerospace company, is a unique opportunity for Australia to capitalize on the new discovery of the Helicon Double Layer Thruster made at the ANU. This will allow the Australian space community to stay abreast of international developments in space propulsion and to be with the fore ....Current-free double layers applied to astrophysical objects and space propulsion. The collaboration between the ANU research group and European Aeronautic Defence and Space Company (EADS) ASTRIUM, the largest European aerospace company, is a unique opportunity for Australia to capitalize on the new discovery of the Helicon Double Layer Thruster made at the ANU. This will allow the Australian space community to stay abreast of international developments in space propulsion and to be with the forerunners of this new technology. ANU will have direct access to EADS-ASTRIUM via the relationships developed in this project putting Australia in the enviable position of being an insider in future space developments concerning plasma thrusters and space technology in general.Read moreRead less
Isotopic fractionation in planetary atmospheres. Ongoing changes in the Earth's atmosphere, such as ozone depletion, demonstrate the need to understand atmospheric photochemical processes. Isotopic fractionation is one vehicle for obtaining
detailed insight into these processes. The proposed research will
increase our understanding of fundamental molecular processes and use these new results to improve our knowledge of isotopic fractionation in planetary atmospheres. The resulting models wil ....Isotopic fractionation in planetary atmospheres. Ongoing changes in the Earth's atmosphere, such as ozone depletion, demonstrate the need to understand atmospheric photochemical processes. Isotopic fractionation is one vehicle for obtaining
detailed insight into these processes. The proposed research will
increase our understanding of fundamental molecular processes and use these new results to improve our knowledge of isotopic fractionation in planetary atmospheres. The resulting models will lead to new insight into the Earth's ozone chemistry and the recent evolution of Titan's and Venus' atmospheres, including how much water may have been present on Venus in the recent past. The research program also enables Australian participation in three international spacecraft
missions.

Ongoing changes in the Earth's atmosphere, demonstrate the need to understand photochemical processes and their role in atmospheric evolution. The proposed research will increase our understanding of the evolution of planetary atmospheres, with concomitant insight into the Earth's evolution. This proposal will greatly enhance the visibility of Australian research, through formal, direct connections to NASA and ESA (European Space Agency) planetary exploration missions, along with publications in Nature, Science, and/or PNAS (Proceedings of the National Academy of Sciences) that will likely result from the high-profile problems to be studied. Furthermore, as a result of this collaboration, Australian students and postdoctoral researchers will benefit from interactions with top international scientists.Read moreRead less
