Another successful collaboration between European Space Agency - ESA and the Centre for Advanced Instrumentation, Department of Physics, Durham University. Link to our new paper "Line-of-sight optical Dome Turbulence Monitor": https://lnkd.in/evq9WVsP Turbulence near a telescope can have significant impact on the performance of optical systems from astronomy through to laser communications. While turbulence in the atmosphere is well understood, there are no good ways to measure turbulence in a confined space. Existing systems tend to use lasers to probe paths across the dome between a transmitter and receiver, however these systems do not sample the line of sight of the primary telescope. We have invented a new technique which looks along the same line of sight as the primary telescope providing a better estimate of the turbulence. This information can be used to minimise the turbulence through actively changing the local environment.

This is a great article by Keri Allan linking climate change, aviation and free-space optical communications. What is the link? Clear Air Turbulence (CAT) This troublesome phenomena is essentially the mixing of air which is invisible to the naked eye and very difficult to predict. If this occurs in regions of air of different temperature and hence density then we get variations in refractive index. The refractive index variations distorts light and is the reason that stars appear to twinkle, and is a major issue for long-range free space optical communications. Modelling and measuring CAT is critical for all these applications.
Did you know that the twinkling of stars in the night sky is caused by clear air turbulence? This is just one of the things I learnt about during my research into CAT for this @Meteorological Technology International article! Thanks to Paul Williams James Osborn Daniel Lennartson, CCM and Junshi Ito for taking the time to discuss this topic with me.

It is brilliant to welcome Alderman Professor Emma Edhem to our new Durham University Space Research Centre (SPARC) team! This is an exciting time in the space sector and for our new initiative. Having experienced and capable people such as Emma on the team will give us the best chance of making a real difference. I am looking forward to working with you in the next years. Thank you Emma!
Professor in Practice Space Economy, Technology & Innovation Durham University and Dept of Economics Durham University / Envoy Space Technology & Innovation / Geopolitical Barrister / Chairman of the Board / Trustee
I am delighted to share that I’m starting a new position as Professor in Practice: Space Economy, Technology & Innovation at the new, exciting, Space Research Centre (SPARC) in Durham University. Here we are forging a new era in space; our Space Research Centre is linking world leading research, impactful partnerships, and industry lead relevant training to ensure we have a sustainable future in space. The Centre is founded on the principle of open, rigorous and independent research to grow the capacity and capabilities of space applications while protecting the space environment for present and future generations. Our vision encompasses not only the pursuit of cutting edge technologies but also the holistic understanding of space and its broader societal, ethical, and environmental impacts. Through responsible, multidisciplinary research, including novel sensors, environment modelling, machine learning, governance and operations, we aim to address the complex challenges and opportunities of space exploration. Our co-partners include the European Space Agency and the Satellite Applications Catapult. Planning is underway for a range of joint research projects, training initiatives access to facilities and participation in space missions. We will invest £5 million over four years in SPARC through the Durham’s Strategic Research Fund which aims to stimulate significant growth in research income for the university through substantial investments in our research community, capability and infrastructure. With an outstanding reputation in space science, our researchers have collaborated with an array of commercial partners, including European Space Agency and NASA. Thank you to the formidable Prof. Joanna Berry 🐝 for introducing me to the brilliant Professor James Osborn . James, thank you for including me in this very dynamic and needed, exciting, research centre relevant to today and future generations to come. I am delighted to be with you at the start. #Space #Research #DurhamUniversity #SpaceEconomy #SpaceTechnology #SpaceInnovation #Sustainability
