Wormlike Structures in Meridiani Outcrop on Mars
Never been to Mars, don't know what it could be :-). Also, by "any natural
process" you probably mean nature on our planet. We simply don't know enough about "nature" on Mars to jump into any conclusions by just looking at some shapes on photographs. Anyway, I havee seen similar "structures" on Earch, too: just look under some rocks after rain. Also, if I look on the picture you posted long enough, I start seeing impressions or faces with distinctly recognizable eyes, nostrils and beaks. Do you think these are fossil impressions? What about those little dark and light grains - bacteria? :-) "Informer" wrote in message ink.net... After Opportunity used the RAT to shave through one of the rocks in the outcrop it revealed at least two puzzling, fossil-like structures. See attached enhancement. Can anyone explain what this might be? One looks like the "positive" and the other the "negative" impression within the folds of the rock. I cannot think of any natural process that would created stuctures like this. They truly look like fossils but I am not jumping to any conclusions. Have a gander for yourself and post your thoughts. |

Wormlike Structures in Meridiani Outcrop on Mars
I think the best way to sum up comparisons Mars and Earth is to borrow the
title from a beautiful color poster of the 2 planets from NASA. It says "Earth and Mars - As Different As They Are Alike" Clear Skies...

Wormlike Structures in Meridiani Outcrop on Mars
If you see here fossiles of worms (and spherules), it might be because the
ancient martian life forms used this place to .. you know. I suppose they don't have any gas evaporation measurement device on board? What a smell! If we ever find life (existing) in Mars, what energy it would possibly use to sustain it's growth? Most of life in earth benefits on other life forms. Even soil is full of life and product of life. The only existing life I could imagine would be something that uses the energy of the Sun. If there were life it had been there a long long time. This means that if we see some we will see a plenty of it or nothing at all.

I suppose they don't have any gas evaporation measurement device on board? What a smell! If we ever find life (existing) in Mars, what energy it would possibly use to sustain it's growth? It could use chemical energy by oxydizing stuff, it could use the energy of mars' molten core (does it have one?) or it could *have* used anything when it was available and have gone dormant since then. Spores can endure hostile environments for a really long time. There is speculation about bacteria being able to endure millions of years in space rocks as long as they are shielded from the radiation. Lots of Greetings! Volker |

The scale:
The drilled area is 4.5 centimeters across. I can't image the structures are more than a couple of millimeters across. "Lesley Robertson" wrote in message ... "Informer" wrote in message ink.net...

At first glance, they looked like bacteria, but in that case, they're far too big for that. Lesley Robertson http://www.beijerinck.bt.tudelft.nl |

Well, yes, but it's another planet, see? Maybe that's what bacteria were on mars. Lots of Greetings! Volker So what? Let's write a fiction novel now! Let's assume then that bacteria (for what it's worth posting this in sci.bio.microbiology :-)) on Mars were huge, sevearl miles in diameter, made of invisible to our eye matter, and had CO2 cell wall.When they rolled down on the surface of the planet, they left markings that we now identify as "Channels", and then when they died, they travelled to poles and decomposed there, leaving huge piles of membranous CO2 behind to form what we call Polar Caps. Or, buy the way, they might as well still live on Mars - under the surface - and use craters as entry ports to their dens. :-) |
