The plasma of comet 67P/Churyumov Gerasimenko is analyzed based on the RPC-MIP mutual impedance probe data of the Rosetta mission. Numerical simulations of the RPC-MIP instrumental response considering two populations of electrons were t on experimental responses acquired from January to September 2016 to extract the electron densities and...

Mutual impedance experiments are a kind of plasma diagnostic techniques for the identification of the in situ plasma density and electron temperature. These plasma parameters are retrieved from mutual impedance spectra, obtained by perturbing the plasma using a set of electric emitting antennas and, simultaneously, retrieving using a set of...

Plasma diagnostic instruments are carried into space by satellites to measure in situ the properties of space plasmas. However, due to spacecraft charging, satellites perturb the surrounding plasma, that reacts by enveloping the platform and its instruments with a short scale, strongly inhomogeneous plasma region called plasma sheath. Such...

The Waves of HIgh frequency and Sounder for Probing Electron density by Relaxation(WHISPER) instrument, is part of the Wave Experiment Consortium (WEC) of the CLUSTER IImission. The instrument consists of a receiver, a transmitter, and a wave spectrumanalyzer. It delivers active (when in sounding mode) and natural electric field spectra....

We study the evolution of a cometary ionosphere, using approximately two years of plasma measurements by the Mutual Impedance Probe on board the Rosetta spacecraft monitoring comet 67P/Churyumov-Gerasimenko (67P) during August 2014-September 2016. The in situ plasma density measurements are utilized to estimate the altitude-integrated electron...

Context. The Mutual Impedance Probe (RPC-MIP) carried by the Rosetta spacecraft monitored both the plasma density and the electric field in the close environment of comet 67P/Churyumov–Gerasimenko (67P), as the instrument was operating alternatively in two main modes: active and passive. The active mode is used primarily to perform plasma...

Mutual impedance experiments are in situ plasma diagnostic techniques for the identification of the plasma density and the electron temperature. Different versions of mutual impedance instruments were included in past and present space missions (e.g., Rosetta, BepiColombo, JUICE and Comet Interceptor). New versions are currently being devised...
