Why? What do you base your opinion on? At the moment there are many
geological interpretations for these. You have jumped to a conclusion
based on your own imperfect analysis. I offered an alternate
explanation for your light and dark spherules. But you ignored that,
didn't you? Instead, you cling to your conclusion. Who has the open
mind here? I'm sorry, but that sort of thing is the sign of a closed,
irrational mind. Sorry, there just isn't any nice way to say that! You
are proceeding very unscientifically, nd let me warn you right now,
without the scientific method we are adrift, able to believe anything we
wish to believe, regardless of the truth.

Too much prudence Greg, the hypothesis of direct life discovery was
eliminated (based on scientists current knowledge and budget) and the
rovers were engineered mainly for geologists (e.g. nasa is not able to
certify true colours pictures !).

I disagree.

As a result of the "geological design" of the rovers, the nature of the
spherules may not be scientifically determined during this missions, due
to the lack of imagination among humans. But this is not the fault of
anyone and I'm not blaming anyone, it is just due to the weak human
thinking structures and ability, the global lack of imagination .
Humility, humility, humility… )

Again, I think you are wrong about this. The science is not that
compartmentalized. We have cameras that can reveal changes over time,
we have instruments that can tell us the composition of the objects. We
even have an instrument that can grind them open to see inside. I fail
to see how these things would miss them as some life form unless they
are very, very subtle forms of life. And if that were true, then I
don't see how we could have designed a mission to look for these life
forms without first having some clues as to what to look for. Again,
you are assuming far too much, both in your analysis and in your narrow
view of the scientists involved.

Lastly, I am not even convinced that these same spherules have been
found at the Spirit site. If these are the same spherules, they are
much smaller... And I see no evidence at all that they are "blue" as
you stated earlier. What evidence do you have for their color? I do
see many tiny grains that look like they have weathered out of nearby
rocks. At the limit of the resolution of the images I'm not ready to
call them spherical. Hey--maybe they are, but I for one require a bit
more evidence before I start considering the implications of something,
with well, rather interesting implications.
