Extended Data Fig. 4: Maximum achievable brine temperature and corresponding water activity of calcium perchlorate brines formed through deliquescence.

From: Distribution and habitability of (meta)stable brines on present-day Mars

Extended Data Fig. 4

To better resolve the habitability of (meta)stable calcium perchlorate brines, here we plot (a) the maximum temperature and (b) corresponding water activity of resulting brines. The latitude range is restricted to non-polar regions. The background is the grey-scaled shaded relief map of Mars based on MOLA data.
