Cometary ion dynamics at a weakly outgassing comet
Victor Steinwand, Peter Stephenson, Zoe Lewis +3
The ESA/Rosetta mission escorted comet 67P/Churyumov-Gerasimenko for two years, exploring its plasma environment across diverse outgassing conditions. Plasma density observations f…
Intercepting Interstellar Objects
Colin Snodgrass, Marina Galand, Arnaud Beth +3
We describe how the ESA Comet Interceptor mission, which is due to launch in 2028/29 to a yet-to-be-discovered target, can provide a conceptual basis for a future mission to visit…
Ion-neutral chemistry at icy moons: the case of Ganymede
A. Beth, M. Galand, X. Jia +1
Icy moons orbiting giant planets are often described as airless bodies though they host an exosphere where collisions between neutral species are scarce. In the case of Ganymede, t…
Cometary ion dynamics at 67P: A collisional test-particle approach with Rosetta data comparison
Zoe Lewis, Peter Stephenson, Arnaud Beth +3
The Rosetta spacecraft escorted comet 67P/Churyumov-Gerasimenko for two years, gathering a rich and variable dataset. Amongst the data from the Rosetta Plasma Consortium (RPC) suit…
Ionosphere of Ganymede: Galileo observations versus test particle simulation
Arnaud Beth, Marina Galand, Ronan Modolo +3
In this paper, we model the plasma environment of Ganymede by means of a collisionless test particle simulation. By coupling the outputs from a DSMC simulation of Ganymede's exosph…
