Abstract The Radio & Plasma Wave Investigation (RPWI) onboard the ESA JUpiter ICy
moons Explorer (JUICE) is described in detail. The RPWI provides an elaborate set of state …

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 …

A major point of interest in cometary plasma physics has been the diamagnetic cavity, an
unmagnetized region in the innermost part of the coma. Here we combine Langmuir and …

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 …

When a weakly outgassing comet is sufficiently close to the Sun, the formation of an ionized
coma results in solar wind mass loading and magnetic field dra** around its nucleus …

Context. The cometary ionosphere is immersed in fast flowing solar wind. A polarisation
electric field may arise for comets much smaller than the gyroradius of pickup ions because …

Context. The electrostatic potential of a spacecraft, VS, is important for the capabilities of in
situ plasma measurements. Rosetta has been found to be negatively charged during most of …

We present and compare measurements of the spacecraft potential (V s/c) of the Rosetta
spacecraft throughout its stay in the inner coma of comet 67P/Churyumov–Gerasimenko, by …

The plasma environment has been measured for the first time near the surface of a comet.
This unique data set has been acquired at 67P/Churyumov–Gerasimenko during …
