Scientists studying pictures from Nasa's Odyssey spacecraft have spotted what they think may be seven caves on the surface of Mars. well I guess that makes habitats a much easier task of creating now, plus with whatever we find in the walls of Valles Marineris. |

I'm not too surprised at all about this find. I've suspected some small but collapsed cave like structures on some of the HiRISE JP2 images. These particular ones from Odyssey are HUGE. It causes me to raise an eyebrow or two! ...but only because it seems to support what I already suspected.
I suspect there is an extensive network of caves throughout many parts of Mars that will not easily be detected from satellite. Most of the larger structures should be very deep underground (kilometers). The Martian crust may look sort of like Swiss cheese. Perhaps MARSIS can help in detecting some of the relatively shallow ones. This discovery only provides hints as to where both the missing water and atmosphere on Mars may have disappeared to. Deep underground there maybe caves where the atmospheric pressure is great enough for stable liquid water or ice. I'm talking about places that would be measured in kilometers. But we maybe waiting for a very long time for the REAL evidence because it won't be so easy to find. |
