Multiple nations and private entities are pushing to make landing humans on Mars a reality. The majority of proposed mission architectures envision ‘living off the land’ by leveraging Martian water-ice deposits for fuel production and other purposes. F
Our modeling suggests that micrometeorites are currently far more abundant on the surface of Mars than on Earth, and given the far greater abundance of water and warmer conditions on Earth and thus much more active weather system, this was likely true throughout the history of Mars. Because ...

Water is the compound of hydrogen and oxygen. It is one of the most abundant materials on the surface of planet Earth and definitely the most common liquid, covering approximately 71% of the Earth's surface. Water also occurs in its solid form, ice, an...
(II)-phosphate minerals for natural waters that co-exist with vivianite (“Methods”). These results show, for example, that when vivianite is present, pore water saturation states are poised precisely at equilibrium vivianite solubility, in turn reconciling variable reports of phosphate mineral ...
