The theory and observations relating to the ionospheres of the terrestrial planets Venus, the
earth, and Mars are reviewed. Emphasis is placed on comparing the basic differences and …

Our current knowledge of the spatial structure of the Venus ionosphere and its temporal
behavior is reviewed, with emphasis on the more recent Pioneer Venus measurements and …

An analysis of Mars and Venus nightside electron density profiles obtained with radio
occultation methods shows how the nightside ionospheres of both planets vary with solar …

Venus has been more frequently studied by space missions than any other planet.
Consequently, we know more about the solar wind interaction with Venus than with any …

Vector velocities of O+ ions in the Venus ionosphere are reported for the dawn and dusk
terminator regions. The velocity vectors are generally directed antisunward and radially …

Measurements of electron density and temperature by the Pioneer Venus orbiter electron
temperature probe have been employed to examine the characteristics and morphology of …

The nightside ionosphere of Mars could be produced by electron precipitation or by plasma
transport from the dayside, by analogy to the Venus, but few measurements are available …

Shrouded by the thick clouds of hot, dense atmosphere, the planet Venus-Earth's closest
neighbour in space-remained mysterious until recent decades. Today, with data from …

We review here observations and models related to the chemical and thermal structures,
airglow and auroral emissions and dynamics of the Venus thermosphere, and compare …

The investigations of Venus take a special position in planetary researches. It was just the
atmosphere of Venus where first measurements in situ were carried out by means of the …
