The chemistry of protonated species in the martian ionosphere

Icarus, 2015
Abstract The Mars Atmosphere and Volatile Evolution Mission (MAVEN) spacecraft entered orbit around Mars on 22 September 2014. The Neutral Gas Ion Mass Spectrometer (NGIMS) instrument on this spacecraft will measure the ion densities with unprecedented sensitivity of ∼1  cm - 3 above the nominal periapsis altitude ∼150 km.

Observations of Vertical Reflections from the Topside Martian Ionosphere

Space Science Reviews, 2006
The Martian ionosphere has for the first time been probed by a low frequency topside radio wave sounder experiment (MARSIS) (Gurnett et al., 2005). The density profiles in the Martian ionosphere have for the first time been observed for solar zenith angles less than 48 degrees. The sounder spectrograms typically have a single trace of echoes, which are

Numerical Simulation of Martian Ionospheric Irregularities

Journal of Geophysical Research: Planets
Abstract Martian ionospheric irregularities have been observed via Mars Atmosphere and Volatile EvolutioN (MAVEN) in situ measurements, but their generation mechanism is still unclear. In this work, we develop a two‐dimensional model to investigate the formation of Martian irregularities.

Ion chemistry in the Martian dayside ionosphere

The ion composition of the Martian ionosphere is controlled by the ionisation of the neutral species (mainly CO2, CO and O) in the upper atmosphere and the chemical reactions that follow. The primary ions, CO2+ and O+, are reactive with O and CO2, respectively, as to produce O2+, which is the dominant ion species in the ionosphere.
