Fancy a summer swim on Mars?

The new data from NASA's Mars Reconnaissance Orbiter suggests that the water still might be flowing on Mars during the warmest season. The characteristic features that water streaming down a slope leaves on the soil can be observed during martian summer. They disappear during winter only to reemerge next spring. Funny how the history of water on Mars went the whole circle. From the guy who first observed the channels and claimed there was liquid water and can be blamed for all those Martians in SF to complete rejection of his findings later making him a laughing stock to everyone being pretty much certain there is water on Mars but it's all frozen and, finally, to this. Still no Martians, though.

It's too cold on Mrs for liquid water to exist so right now the working hypothesis is that this is brine as salt lowers the melting temperature of water. Still the fact that it is there  means much easier access of any human expedition. It can be collected on surface in the lower latitudes during summer instead of mined near the poles. This would let humans stay in the nicer, easier manageable temperatures. And at least terraforming is looking more manageable with every such step.

In other water news NASA is launching tomorrow new probe that is to look for Jupiter's missing water. Previous Gallileo mission didn't find nearly as much water as it was expected so now Juno is going with better equipment to look for it. No water deficit in solar system.

And if you want to know more about where else we expect water to be in solar system io9 has a handy chart.
