Possible Active Glacier Found On Mars 143

Posted by ScuttleMonkey from the dr-neukum-forever dept.
FireFury03 writes "The European Space Agency's Mars Express spacecraft has spotted an icy feature which appears to be a young active glacier. Dr Gerhard Neukum, chief scientist on the spacecraft's High Resolution Stereo Camera said 'We have not yet been able to see the spectral signature of water. But we will fly over it in the coming months and take measurements. On the glacial ridges we can see white tips, which can only be freshly exposed ice'. Estimates place the glacier at 10,000 — 100,000 years old."

Distilled water tastes "flat" and "lifeless" to a lot of people and I'm sure that water that's been distilled from urine a few hundred times on a spaceship will not taste very good at all.

All that subsurface ice needs to be melted to bring the oceans back and build a decent atmosphere, one better at deflecting solar radiation.

      Without it we'd have to wait tens of thousands of years, or more, while specially engineered plant life (very basic plant life) and such worked its slow magic on the atmosphere. With a bit of global warming technology (TM) we can shorten the time considerably. If oceans were brought back the process would be much faster.

Personally, since I won't be alive in either case, a thing I have in common with everyone reading this, I'd go for the slower option, or even go for the option of spending a few hundred years seeing if there were any remnant native organisms that could be helped back into activity and do the job for us.
