Nicolas Thomas gained his PhD at the University of York in 1986 and, after working at the European Space Research and Technology Centre in Noordwijk and the Max-Planck-Inst. für Aeronomie in Katlenburg-Lindau, he became professor of experimental physics at the University of Bern in 2003. He has worked on numerous space missions connected to comets such as Giotto, the Giotto Extended Mission and NASA’s Deep Space 1 as well as several other missions connected to Solar System targets. He leads a research group that studies cometary dusty-gas dynamics, polar processes on Mars and atmosphere-magnetosphere interactions at Io, through modelling, data analysis and laboratory experiment. He is PI of the CaSSIS instrument for ESA’s ExoMars Trace Gas Orbiter and of the Comet Camera (CoCa) on ESA’s new cometary mission, Comet Interceptor.
Ekkehard Kührt received his PhD at the Humboldt-University of Berlin in 1982. His scientific career began at the East-German Institute of Cosmic Research where he contributed to the Russian space missions VEGA and Phobos. After a 2 years stay at the Max-Planck-Institute of Aeronomy in Katlenburg-Lindau with a research grant of Leopoldina Academy he started his scientific engagement at the German Aerospace Center in 1992 where he was head of department “Asteroids&Comets” in the Institute of Planetary Research from 1997 to 2020. He has been and is directly involved in many space missions as Rosetta, BepiColombo, Hayabus-2, MMX, Comet Interceptor.
He is the first or co‐author of more than 250 scientific publications, holds 4 patents and managed international research projects as Rosetta and MiARD in responsible position.This book gives a status report on where we stand today in studies of cometary nuclei and their immediate environment. The papers were derived from a Horizon 2020 project called MiARD (Multi-instrument Analysis of Rosetta Data), which was designed to use multiple datasets from the Rosetta mission to comet 67P/Churyumov-Gerasimenko to place further constraints on the properties of the nucleus of the comet and its immediate environment.
The individual chapters are the result of a significant effort by leading researchers to establish clear statements on what we know from current cometary data. Based on a workshop held in 2018 at the International Space Sciences Institute, the book focuses on the nucleus itself and the relationship between the surface properties and the observed outgassing. Additionally, it makes a first critical assessment of the Rosetta dataset, establishing what would be an appropriate next step in cometary research.Previously published in Space Science Reviews in the Topical Collection "Comets: Post 67P / Churyumov-Gerasimenko Perspectives”
