The water of Mars.Focuses on research related to the possible existence of life and availability of water on the planet Mars with reference to conditions on earth.Lee, PascalOdyssey
These habitable conditions fall under four broad categories: 1) a source of energy; 2) the availability of chemical nutrients; 3) favorable environmental conditions; and 4) accessible water (e.g., Jakosky and Shock, 1998; Cockell et al., 2016). Each of these habitability conditions can ...
However, estimates for the composition of the Martian core have been previously based mainly on either geochemical grounds11,17,18or on seismic and geophysical observations of the mean core density and tidal response of Mars4,5,6,7,8. Moreover, the plausible candidates likely to make up the ...

Water availability across the globe plays a crucial role in shaping livelihoods, socioeconomic development, and ecosystems. However, it is anticipated that this availability will undergo substantial transformations in the next few decades due ...
a role in water loss, but findings from the last decade of Mars missions have pointed to the fact that there was this huge reservoir of ancient hydrated minerals whose formation certainly decreased water availability over time," said Bethany Ehlmann, Professor at California Institute...
■ This has resulted in a more stealthy style of feeding, with the consequent emphasis on lures and/or the evolution of elongated appendages that increase the active volume of water controlled or monitored by the animal. ■ Another consequence of the limited availability of prey is that many ...
Sand mobilized by wind forms decimeter-scale impact ripples and decameter-scale or larger dunes on Earth and Mars. In addition to those two bedform scales, orbital and in situ images revealed a third distinct class of larger meter-scale ripples on Mars. Since their discovery, two main hypothes...
The suite of science instruments on EMM has been carefully chosen to acquire the observations needed to retrieve the key quantities for characterizing the lower atmospheric state, which include surface and atmospheric temperature, column optical depth of dust and water ice aerosol, and column abundance...
Our results show that even brine seeps, although they represent local regions of water availability, could be deleterious to cells, indigenous or contaminant if, as spectral evidence suggests, they contain perchlorates. The enhancement of the bacteriocidal properties of perchlorates by UV-irradiation ...
