Water on Mars: Nasa reveals briny flows on surface  Dr Joe Michalski, Mars researcher at the Natural History Museum London, where he is part of a world-leading research team investigating the origins of our planet and Solar System, comments on the Ojha et al. Nature Geo paper “Spectral evidence for hydrated salts…” “These results provide strong evidence that salty water occasionally flows on the Martian surface, even today. We know from the study of extremophiles on Earth that life can not only survive, but thrive in conditions that are hyperarid, very saline or otherwise “extreme” in comparison to what is habitable to a human. In fact, on Earth, wherever we find water, we find life. That is why the discovery of water on Mars over the last 20 years is so exciting. We have found water in ice form, in permafrost, and in the structures of many types of minerals. This finding is yet another example of water on Mars, but a hugely important one because it points to environments that could potentially be habitable to certain kinds of bacteria, even today. In addition, the discovery of active geological and hydrological processes elsewhere in the Solar System underpins the point that these other worlds are actual places one could visit, where nature is happening every day.” Source |
