Water and methane maps overlap on Mars: a new clue?
Posted by tourdemars to Life on Mars at September 20, 2004 10:55 AM
Recent analyses of ESAís Mars Express data reveal that concentrations of water vapour and methane in the atmosphere of Mars significantly overlap. This result, from data obtained by the Planetary Fourier Spectrometer (PFS), gives a boost to understanding of geological and atmospheric processes on Mars, and provides important new hints to evaluate the hypothesis of present life on the Red Planet.

Sticking to the 'drip' timetable NASA is:
Garvin explained that NASAís Mars Odyssey detected a higher concentration of hydrogen, not necessarily water ice. Mars Odyssey cannot observe "water ice layers", Garvin said, only the presence of hydrogen.
Furthermore, that hydrogen, he added, could be due to hydrated minerals, such as those found on the surface by the Mars Exploration Rovers and also detected from orbit by the Mars Express OMEGA imaging spectrometer.
In Garvinís view, the real test will come when future spectrometers -- such as those destined to fly aboard the NASA Phoenix lander to be launched in 2007, and potentially carried on the Mars Science Laboratory in 2009 -- corroborate the Mars Express measurements.
I'm feeling so 'dripped' on that I need a Martian towel. :D
Garvin n the Joker Poker Geologists running the Lab and still setting the timetable for 'disclosure' of what we already know we know.
There's a FACE n a few Pyramids in Cydonia and LIFE on Mars now.
