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. Fortunately for mission designers, water ice exis...
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...
current understanding of mineral solubility predicts negligible phosphate concentrations for most natural waters, yet the role of Fe2+, ubiquitous on early Earth, is poorly quantified. Here we determine the solubility of Fe
Phosphate-Mobilization on Mars? Implication from Leach Experiments on SNC's [4–6] and in the field upon natural leaching by groundwater. Experiments show that a substantial fraction of the rock phosphate is readily removed both... G Dreibus,E Jagoutz,B Spettel,... - Lunar and Planetary ...

Greater habitat fragmentation has increased polar bear path tortuosity [9], more open water has increased the frequency of long-distance swimming events [105, 115], and increased ice drift speed has increased the cost of station-keeping [5, 34, 90]. Further, polar bears have exhibited shifts...
When organisms are unable to feed ad libitum they may be more susceptible to negative effects of environmental stressors such as ocean acidification and warming (OAW). We reared sea bass (Dicentrarchus labrax) at 15 or 20 °C and at ambient or high PC
Allow at least 7-10 days for delivery, and on average 2-3 weeks turn around time here. Lastly, this catalog includes what we hope is a pretty clear indication of the actual availability of each of these 9,174 items. Our primary distributor has four large warehouses scattered about the ...
