New Clue for Life on Mars?
thhamm writes "Recent analyses of ESA's 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."
It's really awesome, and really amazing, that as we study Mars more, the evidence suggests more and more that life is possible. In other words, the body of evidence isn't ruling life out even as we gather more evidence. It's STILL premature to assume this is life-generated, but its another awesome piece of support for the increased possibility of life.
Moo.
They used the phrases "tens of centimeters" and "tens of degrees celsius". I really hate these terms, especially in what should be a scientific article. This could mean anywhere from 20-100 (or more) which is a pretty broad range. Would it be so difficult to say 20-50 (or whatever the measurements are) which would give a much more accurate picture?
It just seems that there are some spots that might be a little warmer than others, or so goes the hypothesis as I understand it, from geothermal sources. It seems like a little bit of a stretch to link it directly with life on Mars. Perhaps this gives some ideas where to look for life on Mars, but the article itself doesn't seem to make much in the way for claims about Martian life.
Am I reading this wrong?
If I am not, does every discovery about Mars need to really be linked to life for it to be fascinating? Or does the press feel that's the need these days?
Do you know why the road less traveled by is littered with the bones of the unwary?
This is actually a fairly common viewpoint. And its a common way of limiting your viewpoint based on previous experience. Life must be carbon based, requires oxygen and water to survive. (I think there may be silicon life on earth near deep ocean vents, but I can't remember). Most people do this in there every day lives. Make assumptions based on the experiences they have lived through. Remeber the Earth was flat because it looked that way. The Sun orbits the Earth because it looks that way.
Yeah. If we see the sig of *both* methane and
oxygen then its pretty much a nobrainer there's
life.
Methane on it's own, given mars' current atmosphere
composition is just a teaser. Annnoying, real sexy, but geologic processes could be responsible.
I hope we see lots more surprises. Heck. we are just
starting to play with this place. Its one big planet even though it looks small and I for one pray that no
nasty stupid monkey hobnail boots it before we get
to do serious science...
Do a google search on the Horseshoe Crab, which isn't actually a crab, but a 350 million year old ancestor of spiders. It's blood is actually based on copper rather than iron (hemocyanin) and contains a enzyme called limulus amoebocyte lysate (LAL) which is used to test all pharmaceutical products for bacteria. No-one yet has been able to create this enzyme synthetically, which means that these critters have to be harvested for their blood (around $15000 per vial).

...and hence we will never be able to do anything useful with the place.
To look at a rock in space and say, " I doubt there is life there" is to ignore the fact that we have yet to find a place where life can't exist (maybe the sun...). In essence, if there is energy, then there exists the potential for something to exploit that energy. And more often the not, something does.
The question should be "What is living on this rock, and why can't I find it?"
