Modification of Martian Ionosphere

IEEE Transactions on Plasma Science, 2021
To partially meet the communication requirements in Mars, low-frequency ground-to-ground communication is likely to be used in the future and hence, it is desirable to increase electron density in the Martian ionosphere. As a convenient means to this, we have proposed and explored the production of high electron density regions in the Martian ...

Martian Ionospheric Magnetic Fluctuations

2023
Understanding the properties and variability of the ionosphere is vital for understanding the atmosphere of Mars. The presence and property of waves provide insight into the plasma and magnetic environment. We conducted a search for 5 - 16 Hz signals below 400 km in magnetic field data from Mars Global Surveyor (MGS), the Mars Atmosphere and Volatile ...

On the extent of the Martian ionosphere

Journal of Geophysical Research, 1973
The boundary of the Martian ionosphere just above the photochemical layer, where solar-wind induced convection becomes important, is estimated. The Martian ionosphere is expected to terminate at an altitude of approximately 300 km.

Electron Temperature in the Martian Ionosphere

Publications of the Astronomical Society of Japan, 1972
Abstract Electron temperatures in the Martian ionosphere at the times of Mariner 4 and 6 missions are calculated in the continuous slowing down approximation by using new molecular data. It is concluded that thermal equilibrium between electron and neutral temperatures in the lower part of the ionosphere may exist only when the solar ...

Photoelectron fluxes in the Martian ionosphere

Journal of Geophysical Research: Space Physics, 1979
The equilibrium photoelectron distribution in the upper atmosphere of Mars is calculated and compared with a typical theoretical model of the photoelectron distribution in the upper atmosphere of the earth. The neutral upper atmosphere and ionosphere models used in the calculations for Mars are based on the Viking 1 neutral mass spectrometer and ...

The Solar Wind Interaction With the Martian Ionosphere/Atmosphere

Space Science Reviews, 2006
The interaction of the solar wind with the Martian exosphere and ionosphere leads to significant loss of atmosphere from the planet. Spacecraft data confirm that this is the case. However, the issue is how much is actually lost. Given that spacecraft coverage is sparse, simulation is one of the few ways for these estimates to be made. In this paper the
