Interesting, sure. (I heard it first on Cumbrian Sky - thanks Stu.)
But probably best not discussed here. |

Indeed - it's in direct breach of forum rules.

That's not why it's against forum rules.

I was checking some stuff from Mars Global Surveyor and then I came across this image: http://ida.wr.usgs.gov/fullres/divided/r09011/r0901196a.jpg
You could see the rest here: http://ida.wr.usgs.gov/html/r09011/r0901196.html It's very strange! -------------------- www.espaciosur.com.ar | astronomía para todos

Those are dust deposits left on the south polar ice from abrupt sublimation of subsurface CO2 deposits as spring approaches, Loiseri. 2006 BBC story.

Interesting paper in JGR: Arkani-Hamed, J. (2010), Possible crippling of the core dynamo of Mars by Borealis impact, J. Geophys. Res., 115, E12021, doi:10.1029/2010JE003602. Pay-for article abstract link: http://www.agu.org/pubs/crossref/2010/2010JE003602.shtml
According to the author, the whack that formed Vasitas Borealis may have also "quenched" the core. Did 120 Myr of no magnetosphere permanently alter Mars's evolutionary path? -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

And some support for this theory comes from different instruments.
Here is evidence from Odyssey's GRS spectrometer - http://www.watergeek.net/geek/GRS_oceans_in_press.pdf -------------------- |

QUOTE (Fran Ontanaya @ Feb 7 2012, 02:33 AM)  ESA's Mars Express radar gives strong evidence for former Mars ocean Emily's Blog http://www.planetary.org/blog/article/00003365/ discusses this work (by Mouginot et al., in GRL) in nice detail. There is a contour of dielectric constant that matches other estimates of the extent of Oceanus Borealis : this must surely be the 'Mouginot Line'........ |

Thanks, Ralph. I may require surgery to remove the wince from my face....
