Viking Landers Might Have Missed Martian Organics 82
Sonny Yatsen writes "A new study suggests that the Viking Landers might have found organic compounds on Mars, but failed to recognize them because of the methodology used to detect organics. The findings may suggest specific strategies that would improve on the way organic compounds are detected on the red planet."

TFA says that any organic compounds which might have been found would have been destroyed by heating perchlorate to 200-500C. I remember reading something similar to this a while back here on /. (but I don't have a link handy).

But NASA invalidated the tests [utk.edu]
The results of these experiments were complex. The first three gave positive results, but the complete absence of any organic compounds in the Martian soil according to the mass spectrometer experiment suggests that the positive results for the first three were not evidence for life, but rather evidence for a complex inorganic chemistry in the Martian soil. Thus, the Viking verdict was that there was no evidence for present or past life on Mars.

An interesting link. But, no, as it says, they didn't find organics. Finding organic (!= biological) compounds is what the 4th experiment was about and it came up negative (other than what they assumed were contaminants), and it's the results of that 4th experiment that are in question today.

For christ's sake, 'methodology' is the study of methods. Stop using big words whose meaning you don't know!
LOL, back at ya, genius [reference.com].

Your parent post is correct. Methodology is either the study of methods or a system or organized approach or set of methods. A few methods does not make a methodology at all.
