#1 Re: Unmanned probes » Disappointment pictures from titan » 2005-01-16 15:09:07

O.K. there is a couple of people trying to make the best out of the images:

I hope for some interesting data from the gas chromatograph.

Who was responsible for not switching on the second transmitter ? NASA or ESA ?

Anyway - that was ...... missing words...

#8 Re: Unmanned probes » A puddle ? » 2004-05-04 05:02:35

Thank you for your thoughts, cassioli.

But I have no confirmation yet.

Strange...I asked this question a couple of times but never got a "yes" or "no".

I seems to me that the rovers are not equipted to detect surface or subsurface water (ice, brine).

#9 Re: Unmanned probes » A puddle ? » 2004-05-03 11:35:42

I wish that NASA would decide to test that hypothesis.

But I think their attention is fixed to the bigger "puddle" now.

Can't wait to see more images...

By the way:

Does anybody know if the rovers would be able to remote sense liquid water (brine, acid) or ice (snow) on the surface ?

#10 Re: Unmanned probes » A puddle ? » 2004-05-03 05:55:05

But what happened to the berries at the puddle area ?

Why is this area berry-free ?

"What the hell is there, under the red dust of 'Mazatzal'?!?"

Good question ..

There is a coating rich in chlorine ans sulfate:

[http://marsrovers.jpl.nasa.gov/gallery/ … 7R1_br.jpg]http://marsrovers.jpl.nasa.gov/gallery...._br.jpg

There are at least two layers inside the coating

( see [http://marsrovers.jpl.nasa.gov/gallery/ … 0401a.html]http://marsrovers.jpl.nasa.gov/gallery/ … 0401a.html )

Below that coating is basalt.

NASA:
"Its outer coating or rind, on the other hand, appears to be of a different constitution. Scientists are still puzzling out the implications of these data."

Any ideas about the coating ?

"Which brings me to a puzzling observation: The lack of rocks at Eagle crater and its general area."

Interesting. That question did come to my mind suddenly yesterday, too.

I have no explanation....

any geologists ?

#15 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-15 15:05:15

Interesting find..I'm not sure...could be something moving..could have been a hidden rock...

interesting !

#16 Re: Unmanned probes » Sphere triplets??? » 2004-03-12 03:02:50

Reminds me of proliferating yeast. See the following site for visible example:

[http://www.ifr.bbsrc.ac.uk/ncyc/Default.html]http://www.ifr.bbsrc.ac.uk/ncyc/Default.html


Of course there is a big gap regarding dimensions (a yeast cell is only a few microns long).

And I would find it very unlikely if these marbles were single celled organisms.

I could rather imagine some kind of a higher developed spherical bacterial colony...or the fruit body of some kind of "mushroom" living inside rocks or inside soil..or...whatever...

#17 Re: Unmanned probes » Broken spherele has dark spot inside it???? » 2004-03-09 07:24:28

Yes...and...

Look at that one ...

[http://marsrovers.jpl.nasa.gov/gallery/ … 52M2M1.JPG]http://marsrovers.jpl.nasa.gov/gallery....2M1.JPG

It looks like (JUST SPECULATION !!!) the big "thing" has two "channels" connecting it to one of the marbles.

The lower left marble shows bifurcation (mirror symetry) again....

#18 Re: Unmanned probes » Broken spherele has dark spot inside it???? » 2004-03-09 05:32:23

Very interesting indeed.

Seems that we have a couple of new interesting marbles in the new images:

1. A flattened type (like a sphere deformed from pressure from one or two sites)

[http://marsrovers.jpl.nasa.gov/gallery/ … 33M2M1.JPG]http://marsrovers.jpl.nasa.gov/gallery....2M1.JPG

2. A marble with a "leaf like" substructure

[http://marsrovers.jpl.nasa.gov/gallery/ … 53M2M1.JPG]http://marsrovers.jpl.nasa.gov/gallery....2M1.JPG

Does it point toward any haypothesis or against any hypothesis ?

Any explanations ? New Hypothesis  ?

All I can say is "strange, strange, strange..." but that means nothing...

The "leaf" looks particular starange, doesn't it ?

#23 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-05 06:32:41

Ups...I thought it was the most recent. Or is it ?

I meant a recent (2003) paper stating that the geometry and orientation (in chains) of magnetite crystals inside the ALH globules can only be explained by the action of bacteria.

I will google again and come back later...
Does anyone else remember ?

Yes there was a back and forth on this topic for quite a while, but since that relatively recent paper there was no more "against life paper" coming up.

#24 Re: Unmanned probes » Spirit & Opportunity*4* - continue here » 2004-03-04 15:30:34

The latest results on ALH84001 brought some very strong evidence for bacteria. See for yourself:

[http://ares.jsc.nasa.gov/astrobiology/b … -28-01.pdf]http://ares.jsc.nasa.gov/astrobi....-01.pdf

Muliticellular Life ???

Why not ?

We have no example for what happened on mars.

Billions of years of evolution of a whole planet under water shortage conditions...bringing certain kinds of evolutionary pressure ( need for UV protection or nearly water dense hull,...).

It's hard to tell.

To Shaun Barrett:

You spoke directly from the bottom of my soul.

I feel some old paradigms are going to fall in the not so far future.
