Estimation of the total electron content of the Martian ionosphere using radar sounder surface echoes

[1] The Martian ionosphere’s local total electron content (TEC) and the neutral atmosphere scale height can be derived from radar echoes reflected from the surface of the planet. We report the global distribution of the TEC by analyzing more than 750,000 echoes of the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS). This is the first direct measurement of the TEC of the Mar...

Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) after nine years of operation_ A summary

Mars Express, the first European interplanetary mission, carries the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) to search for ice and water in the Martian subsurface. Developed by an Italian–US team, MARSIS transmits low-frequency, wide-band radio pulses penetrating below the surface and reflected by dielectric discontinuities linked to structural or compositional chang...

Martian Surface Radar Reflectivity by Marsis

Introduction: Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) on board Mars Express is a decameter sounder radar, which can work in two different modes : subsurface or ionosphere sounding. The subsurface sounding uses 4 different frequency bands, which are centered to 1.8, 3, 4 and 5 MHz. Each band is 1 MHz wide. [1,2]. In this work, we study the reflectivity of Martian surf...

Radar soundings of the ionosphere of Mars.

We report the first radar soundings of the ionosphere of Mars with the MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) instrument on board the orbiting Mars Express spacecraft. Several types of ionospheric echoes are observed, ranging from vertical echoes caused by specular reflection from the horizontally stratified ionosphere to a wide variety of oblique and diffuse echoes...

The SHAllow RADar (SHARAD) Experiment, a subsurface sounding radar for MRO

SHARAD (SHAllow RADar) is a radar for the study of the Martian subsurface provided by the Italian Space Agency (ASI) as a facility instrument on board NASA’s Mars Reconnaissance Orbiter 2005 spacecraft. The scientific objective of SHARAD is the detection of water, either liquid or solid, and the profiling of subsurface ice layers in the first hundreds of meters of the Martian subsurface. Althou...
