Viking landers may have missed Martian life.<br><br>Here's a snip: [color:blue]Now, a paper by Rafael Navarro-Gonzalez of the University of Mexico and others demonstrates that the GCMS [i. e. the gas-chromatograph mass spectrometer] instrument was incapable of detecting organic compounds even in Mars-like soils from various locations on Earth. This includes Chile's Atacama desert, where other tests prove that living microbes are indeed present.</font color=blue><br><br>____________________________________________________<br>Bliss was it in that dawn to be alive,<br>But to be young was very heaven!

And don't forget, we're looking for life as we know it. Dare we be so arrogant as to assume that "life" cannot be if it isn't what we conclude it is? Poly may thump me with his scientist stick for saying this. But does life require all or only the chemicals, compounds, thingies, and majiggies that are present on earth, or might there be more that we are simply unaware of or incapable of comprehending?<br><br>[Pink Floyd up and under/fade to white/roll credits]<br><br>
No, I think you are right. Or at least since we have never ever met life which did not evolve on this blue marble we should not presume anything about how life on another planet has turned out. It would be stupid to go to the Chilean sea vents for instance and think, "ah, this is a habitat as bad as Mars and these species which evolved here have our DNA/RNA and are really quite similar to us, therefore Martian life should be similar."<br><br>I think Martian life, if we find it, will be similar because of cross contamination. We might be a wee bit martian and life there might be a wee bit terrestrial.<br><br>One of the researchers in the article does speculat that the inter cellular fluid of a Martian might be hydrogen peroxide which would account for the missing meteorite organics. <br><br>What I am surprised at is any scientist who would think a gas chromatograph mass spec constructed 30 years ago could have found anything. A 30 year old GCMS instrument couldn't find organics in my backyard unless I held its hand.<br><br>We need to get a new mass spec up there.<br><br><br><br><br><br><br>
