Possible Active Glacier Found On Mars 143
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."

When it's a choice between that and your own urine, which has been reprocessed through the spaceship urine reprocessing system 700 times, the dirty ice will start to look mighty appealing.
Yes, because, you know, repeated artificial reprosessing of waste will wear out the water molecules. The electrons get all fractured, H-atoms may te twisted to wrong angles, little feces and urine particles may get stuck between the two H-atoms, and so on. Natural prosesses are much better because then the power of the Gaia (in this case the Martian Gaia) will be able to heal the damage in water molecules. And healthy water molecules will have the energy and will to keep themselves clean too, just like

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.
The question is how can it be acheived in a way that can be managed, so it doesn't spin out of control. 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.
That there are active glaciers is fascinating though. What a shame that almost all of the current environment of mars would need to be destroyed or irreversibly altered in order to host our species. It doesn't bode well for our entry into the interstellar club. How ironic if the destructive aliens we worry about so much in fiction turn out to be us.
