Possible Active Glacier Found On Mars
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."
We've known there was ice on Mars for a century or more. It is visible from Earth through any reasonably good telescope. You know, those white things at the poles?
Sure, in winter they get bigger from frozen out CO2, but there's a year-round permanent cap of water ice. Glaciers, permafrost, pingoes and other signs of ice should not be a surprise. Okay, a glacier on the Martian equator might be a surprise, except perhaps on one of the Tharsis Bulge volcanoes or Nix Olympica (er, Olympus Mons to you young whippersnappers; now get off my lawn).
Yet people seem to be surprised every time there's the merest hint, or act like it's of some cosmic significance. Sheesh.

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.
I'm trying to teach myself to set people on fire with my mind... Is it hot in here?
