Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the
exploration of a little-processed long-period comet, possibly entering the inner Solar System …

The environment of a comet is a fascinating and unique laboratory to study plasma
processes and the formation of structures such as shocks and discontinuities from electron …

Context. The Rosetta spacecraft provided us with a unique opportunity to study comet
67P/Churyumov–Gerasimenko (67P) from a close perspective and over a 2-yr time period …

Spacecraft charging is problematic for low‐energy plasma measurements. The charged
particles are attracted to or repelled from the charged spacecraft, affecting both the energy …

Average flow patterns of ions around comet 67P detected by the RPC-ICA instrument
onboard Rosetta are presented both as a time series and as a spatial distribution of the …

Context. The Rosetta spacecraft escorted Comet 67P/Churyumov-Gerasimenko for 2 yr
along its journey through the Solar System between 3.8 and 1.24 au. Thanks to the high …

Context. The direction of the interplanetary magnetic field determines the nature of the
interaction between a Solar System object and the solar wind. For comets, it affects the …

We investigate the atmospheric response to seasonal variations in sea surface temperature
(SST) in the eastern tropical Atlantic during the boreal summer, using the Weather Research …

The interaction between a coronal mass ejection (CME) and a comet has been observed
several times by in situ observations from the Rosetta Plasma Consortium, which is …

Context. Sufficiently far from the Sun, all comets go through a phase of low activity. Rosetta
observations at large heliocentric distances of approximately 3 au showed that the plasma at …
