Simultaneous ionospheric variability on Earth and Mars

[1] Ionospheric physics deals with the basic structure and variability of plasma within the upper atmospheres of the Earth and planets. Comparative studies foster both exploration and synthesis within diverse settings. In this paper we examine observations of the ionospheric profiles on Mars obtained on 9–27 March 1999 by the radio science experiment onboard the Mars Global Surveyor satellite, ...

Crater Fields on Venus , Earth and Mars

Introduction: Meteoroids that are disrupted and dispersed in the atmosphere may give rise to crater fields at the surface. For lower mass objects fragmentation may produce a strewn field of meteorite fragments, and then (with increasing mass) meteorites plus impact pits; small meterto tens m-sized well separated craters; craters whose rims overlap; and finally single craters produced by a swarm...

Mars, Earth Polar Congruencies, Antipodal Conjugacies

The serm morphological, spin-axial, polar antipodal congruencies of Earth, Mars, Venus, extremely unlikely to have happened randomly, are concentric with hemispheric dichotomies, consistent with super huge impact tectonogenesis, otherwise inexplicable. The hemispheric dichotomies of Mars and Venus must be the effects of super huge impacts centred at what more or less were during Johnstonian imp...
