Nestled in the midst of the so-called ‘frozen frontier’, Uranus has been visited only once – a fleeting fly-by accomplished when the Voyager 2 spacecraft managed it in 1986. As one of only eight planets in our solar system, Uranus, along with Neptune, is the only major class of planet yet to have a dedicated mission of exploration.

But this is set to change, as space agencies plan to launch a spacecraft to the outer solar system, investigating Uranus in more detail than ever before – a world that boasts rings, moons and a complex atmosphere. The mission is an exciting one. Uranus spins on its side, and as a result has the most extreme seasons of anywhere we know.

In this hour-long, free-to-join webinar, you will meet scientists who are excited about a mission to the second outermost planet, and the third largest in the solar system. At nearly three billion kilometres from the Sun, there are obvious challenges in launching a mission to travel such a distance and in commanding a spacecraft to perform scientific investigations when it arrives. Throughout the interactive session, our guest panel will share what we’ve already learnt about Uranus, from information gleaned by Voyager as it flew by, and from subsequent advanced ground and space-based telescope studies. They will also explain what the scientific priorities are for a dedicated Uranus mission and what else we can learn by visiting this icy giant.

This webinar will be suitable for anyone with an interest in Uranus, solar system science and space science exploration. We will look in detail at the science of the ice giant, including its origin and evolution, and we’ll delve into the chemistry of its atmosphere – as well as finding out what we know so far about its deep interior. Our panel will also discuss the decisions being made by space agencies around the world as they prepare to launch spacecraft to the outer solar system in future decades.

Athena Coustenis, Director of research

Athena Coustenis is Director of research with the French Center for Scientific Research (CNRS) at Paris Observatory, specialising in astrophysics and planetology. She contributes to the development of space missions and analyses the acquired data to investigate the atmospheres and surfaces of planets, satellites and exoplanets (examples are the Nasa-Esa Cassini-Huygens mission and the upcoming Juice and Ariel Esa missions).

She is currently the Chair of the European Space Agency’s Human Exploration and Science Advisory Committee (Esa-Hesac). She is also the President of the Cospar Panel on Planetary Protection and of the Science evaluation committee of the French National Center for Space Studies (Cnes-Ceres). She is a member of several other international advisory bodies (e.g. Nasa, Esa, and national agencies). Her production record includes about 300 scientific articles, several books or chapters and more than 750 presentations.

Naomi Rowe-Gurney, Postdoctoral research associate

Naomi is a James Webb Space Telescope (JWST) guaranteed-time observer (GTO) postdoctoral research associate at the Nasa Goddard Space Flight Center employed by University of Maryland College Park (Cresst II), US. She is a solar system ambassador for the JWST working with Stefanie Milam and Heidi Hammel. She obtained her PhD in 2021 from the University of Leicester, UK, working with supervisor Leigh Fletcher. Her thesis used archived data from the Spitzer Space Telescope to study the thermal structure and composition of the middle atmospheres of the ice giants, Uranus and Neptune.
