Recent US Decadal Reviews and the STFC Roadmap 2022 have identified the Jovian and Saturnian systems as a major focus for future missions. Indeed at Jupiter, the Juno spacecraft is currently in orbit, Juice is on the way there, and Europa Clipper should launch in Oct. 2024. There are also proposals for future sample return missions to Io. In parallel, Cassini data from the Saturnian system is still being analysed and several major mission proposals have recently been prepared for new visits to the Saturn including a focus on Enceladus. There is thus a wealth of information on both Io and Enceladus, two very different worlds, but both of which (for very different reasons) have plumes ejecting material from their interiors into space.
- Io is the most volcanically active body known, and its (hot) plumes offer a window into the mineral wealth of its interior.
- Enceladus is an icy ocean world, and its (cold) plumes offer insights into the contents of its internal ocean.
Requests for talks/posters are invited on all topics relating to either body. In particular they are sought about:
- our current understanding of these bodies,
- how plumes can be best sampled in future missions and what such sampling missions might reveal,
- and how what we learn about the evolution of the bodies can illuminate the development of small planets/satellites in general.
Requests for talks/posters should have a title, clearly identify both the proposed presenter and all authors (and their affiliations) and the accompanying text should be no more than 1 page of A4 (and can include references if desired). Please send these to Prof. Mark Burchell, m.j.burchell@kent.ac.uk by Oct 15th, 2024, at the latest.
Any enquiries about the meeting should also be made to Mark Burchell (m.j.burchell@kent.ac.uk).
