A selection of images from the Mars probes

The ob_22_reull_v2 is very interesting.


Also the following is a must see.
A very high resolution 5.9 meg.

Take a look at the borders of darker to lighter areas what does it look like? Those who are familiar with aerial photography high altitude here on earth may have a better appreciation of this pic. Use your picture program and magnify...
Enjoy.

I'm no expert but it looks like shrubs or bushes in those two shots.

I highly recommend the picture called athabascafloods easily found on google advanced image search, extra large. It seems they have a problem controlling the water now and then.

Cydonia, If they send a probe there they better put it on a boat.

Why? Looks very dry to me...
Don't see any water on that Cydonia pic...

That b&w pic of the pole which shows what look like shubs or bush
is very interesting though...

Hi guys,

I read parts of this thread, haven't reached my own conclusion because of lack of any expertise in digital imaging, but must say that the subject is interesting.
What do you make of this Youtube video?

I make of it a recap of the by now old "discovery" that
Nasa did not publish most of their pics in "true colour".
It caused quite a bit of ruckus when that first came out
a couple of years ago.
In the mean time the ESA orbiter pictures have confirmed
that the colour of the sand etc on Mars is indeed much
closer to an Earth norm desert colour than any of Nasa's
Viking and later pictures showed.
The original pictures Nasa published from the Mars Rover
were still redshifted, as was easily proven by comparing colour
pictures of the thing here on Earth with those taken by the
thing itself on Mars, and renormalising the yellow cable that
looked orange on the Mars pics. After several groups had done
so, and especialy after the ESA orbiter pictures were published,
all of a sudden Nasa changed its attitude from "No no, you're all
wrong, Mars really does look red!" to "well we don't see what the
fuss is about, just look at our database full of true colour pictures
that show yellowish-brown desert sand and blueish skies... What
do you mean misleading pictures?"...
Now they act as if they never claimed Mars was brick-red at all!
...
just like they first said "there is no water on Mars",
then it very slowly turned into "there might be some water ice on Mars"
and now just the other week newspapers bellowed "Nasa finds water on Mars!"...

Hmmm... what will be next?
I'm waiting for Nasa to change their opinion about the Martian atmosphere
from "there's no breathable air on Mars" via "there might be air that could be
breathable for a little while, on Mars" to finally read in the newspapers
"Nasa finds Martian atmosphere breathable!"...



Anyway, that youtube video is mostly correct, looks like.
