Martin Volwerk is a permanent member of staff at the Space Research Institute of the Austrian Academy of Sciences, Co-Investigator on the JUICE magnetometer and those on other missions, and national Co-Principal Investigator on the Comet Interceptor mission. His thirty-year career as a planetary plasma physicist has focused on studying plasma interactions at the Galilean moons, ultra-low frequency waves in planetary magnetospheres, and cometary plasma physics. Melissa McGrath is a senior scientist at the Carl Sagan Science Center, SETI Institute. She has had a distinguished career with over thirty years of experience as a planetary scientist studying Jupiter's four large Galilean satellites: Io, Europa, Ganymede and Callisto. She has worked on numerous NASA missions, including the Hubble Space Telescope, and the upcoming JUICE and Europa Clipper missions, and she has held leadership positions at NASA, the International Astronomical Union, and the American Astronomical Society. She has also served as a scientific editor for The Astrophysical Journal. Xianzhe Jia is a Professor at the University of Michigan. He is a space physicist with expertise in combining computer simulations with spacecraft measurements to study magnetic fields and plasma phenomena in planetary environments. He is Co-Investigator on the JUICE and Europa Clipper missions currently under development for exploration of the Jupiter system. Tilman Spohn is a planetary scientist at the International Space Science Institute in Bern, Switzerland. His work focuses on modelling the interior structure and thermal evolution of planets and icy satellites, with a particular emphasis on their cores and magnetic field generation. He has led instrument teams on the NASA InSight mission to Mars and the ESA Rosetta mission to comet 67P/Churyumov-Gerasimenko. He is an American Geophysical Union Fellow and a recipient of the Runcorn-Florensky medal, awarded by the European Geosciences Union for exceptional contributions to planetology. He is also a member of the Academy of Astronautics and of Academia Europaea.
