I think this is old news? Why is S&T suddenly catching on?

Question: do the MGS and Mars Odyssey imaging systems have the capability to
resolve a cow? I've got a theory, but I'm not ready to discuss it, yet... ;-) Jon |

I same the global map at the GSA a few days ago.
The weird thing is the methane abundance varies systematically with longnitude, e.g. one side of Mars is gassy and the other side low. This doesnt correspond with the major geological trends which are latitudnal. |

George Well the 'life on Mars' theory might cath on if this proves to be true and is recognised as a sign of life. Let's hope this put's some fire under the buts of the peaple that are still trying to delay a manned mission to Mars. -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/ |

Seems to me the prevailing winds would determine how the methane was distributes with respect to the point of origin. -- Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/ |
