Mars Express scopre un nuovo strato ionosferico

Mars Express scopre un nuovo strato ionosferico

MaRS is using the radio signals that convey data and instructions between the spacecraft and Earth to probe the planet's ionosphere, atmosphere, surface and even the interior. Information on the interior can be gleaned from the planet's gravity field, which will be calculated from changes in the velocity of the spacecraft relative to Earth. Surface roughness will be deduced from the way in which the radio waves are reflected from the Martian surface. Credits: ESA/C.Carreau
