, 4 years ago→Could oxygen get into rapidly forming droplets where salt forms on ice?
Line 163:
::'''VS''': Just like the answer above. Dynamics is still to be explored. (But this is a really good question 😉).
[[File:Mars-SubglacialWater-SouthPoleRegion(cropped).jpg|thumb|Possible 20-km wide subglacial lake close to the Martian south pole. The dark blue region in the overlayed scans, lower middle, is thought to be a radar bright echo from extremely cold brines, probably magnesium and calcium perchlorates at a depth of 1.5 km. Vlada Stamenković et al's model would suggest high solubility for oxygen for these brines too, and he suggested oxygen could get into them through {{w|Radiolysis|radiolysis}} from natural radioactivity of the rocks below.]]
:: {{WNIQ}} Any idea of timescale yet for the oxygen to be taken up - is this hours, days, months, years? E.g. could oxygen get into water from melting of morning frosts, and ice melting briefly in the Hellas basin or is this impossible on such a short timescale (if you know)? Similarly for the deliquescing salts that Curiosity found beneath its wheels as it drove over the sand dunes, that form overnight and dry up during the day
::'''VS''': This is still fully under investigation, so there’s unfortunately no info on this yet.
