Of Martian atmospheres, oceans, and fossils
Icarus, 1990 Abstract Based on the absence of extensive cratering on the northern Martian plains, it is suggested that these plains were the sites of ancient oceans, 2 to 3.5 Gyr ago, with a calculatable water depth of (≥) 0.7 km. Also it appears possible to interpret the crater density counts for Chryse and the highlands as implying that Mars had a fairly dense ...

Global Model of Atmospheric Chlorate on Earth
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.Abstract Naturally occurring chlorate (ClO3−) has been observed on Earth and potentially plays important roles in hydrology and mineralogy on Mars. However, natural sources of chlorate are uncertain. Here, we quantify the importance of atmospheric sources of chlorate.

Photovoltaic array for Martian surface power [PDF]
Missions to Mars will require electric power. A leading candidate for providing power is solar power produced by photovoltaic arrays. To design such a power system, detailed information on solar-radiation availability on the Martian surface is necessary.

Observation of pressure variations in the Martian atmosphere
Geophysical Research Letters, 2003 Pressure waves in the Martian atmosphere could so far be observed only in the presence of clouds. Thanks to the Mars Global Surveyor/Mars Orbiter Laser Altimeter (MGS/MOLA), a direct observation is now possible, with the method presented here. Many more events are thus potentially observable. We compare altimetry measurements from MGS/MOLA and spectral

A First Look at Carbon and Oxygen Stable Isotope Measurements of Martian Atmospheric C02 by the Phoenix Lander [PDF]
, 2009 Precise stable isotope measurements of the CO2 in the martian atmosphere have the potential to provide important constraints for our understanding of the history of volatiles, the carbon cycle, current atmospheric processes, and the degree of water/rock ...

The chemical effects of the Martian environment on power system component materials: A theoretical approach [PDF]
In the foreseeable future, an expedition may be undertaken to explore the planet Mars. Some of the power source options being considered for such a mission are photovoltaics, regenerative fuel cells and nuclear reactors.

Effects of Martian Dust Storms on Ionospheric Peak Altitudes
The Astrophysical JournalThe effects of Martian dust storms on the atmosphere and ionosphere is one of the hot topics in Mars research. This paper reports on the effects of a local dust storm on the ionospheric peak altitude based on electron density profile observations from ...

Martian meso/micro-scale winds and surface energy budget [PDF]
, 2011 Regional, diurnal and seasonal variations of surface temperature are particularly large on Mars. This is mostly due to the Martian surface remaining close to radiative equilibrium.
