MoMo: a new empirical model of the Mars ionospheric total electron content based on Mars Express MARSIS data
Peter, Kerstin; Witasse, Olivier; Kofman, Wlodek +5 more
Aims: Several scientific landers and rovers have reached the Martian surface since the 1970s. Communication between the asset (i.e., lander or rover) and Mars orbiters or Earth antennas uses radio signals in UHF to X-band frequencies passing through the Mars' ionosphere. It is consequently necessary to take into account electron density variation …
Estimating the solar wind pressure at comet 67P from Rosetta magnetic field measurements
Madanian, Hadi; Timar, Aniko; Nemeth, Zoltan +3 more
Aims: The solar wind pressure is an important parameter of space weather, which plays a crucial role in the interaction of the solar wind with the planetary plasma environment. Here we investigate the possibility of determining a solar wind pressure proxy from Rosetta magnetic field data, measured deep inside the induced magnetosphere of comet 67P…
