We present the first long‐term characterization of ionization layers in the lower ionosphere of Mars (below ∼90 km), a region inac...
The polar ionosphere of Mars as seen by Mars Express-MARSIS during a full solar cycle
SPACE ENVIRONMENTS AND WEATHER OF UNMAGNETIZED OR WEAKLY MAGNETIZED SOLAR SYSTEM BODIES II POSTER
planetary sciences | 16 december 2021
Beatriz Sanchez-Cano, Mark Lester, Marco Cartacci,...
Since Mars does not have a global intrinsic magnetic field, the variability of Mars polar ionosphere is due mainly to the solar irradiance flux and ne...
