Re: Infrared detection of liquid water on Mars?
Odd.
Compare here: (Taken with Hubble IR camera)
http://oposite.stsci.edu/pubinfo/pr/1999/07/
Which shows Acidalia as wettest, compared to any other area on this hemisphere. (Visual imagery shows lots of sploshy craters here and what looks like icy terrain as well)
To this image: (Odyssey Gamma Ray Spectrometer)
http://science.nasa.gov/headlines/y2002/28may_marsice.htm
Which seems to show either a very dry Acidalia (and oddly "wet" Arabia) or shows something masking water sign in Acidalia.
Can anybody explain?
This being Mars, it wouldn't surprise me if they were both "true." But how?
