For WOGIT: Google Mars Some of the ESA photos over the last year or so do show "green" in Valles Marinaris. Too bad the pixel per meter count is so low.

That is a rediculous statement I have seen many here that certainly do not have an open mind and go to great lengths to tell other people they are wrong. As to wasting time, I am really quite sure I can decide myself how best to spend my time. And since NASA scientist who are paid to speculate on the images they see do the same thing we do, and even post images with cute names the same as we do, who are YOU to tell us we are wasting our time? It was NASA who first started the "Face on Mars" thing, thinking it was a good way to get ordinary people involved in whats going on on Mars... This was 25 years ago and it worked, as its still going...

I've seen a plethora of threads on this subject recently - and I find myself asking - what does it amount to? NOTHING!

And your going to see a LOT MORE as NASA and ESA continue to bring us interesting images from off world... Have a look at this page... Malin Space systems Heart shaped craters colored pink by NASA scientists...

Happy Valentine's Day 2004

If it offends you, it wasn't directed personally.

In this paper we define and describe morphological features that have colloquially been termed "spiders" and map their distribution in the south polar region of Mars. We show that these features go through a distinct seasonal evolution, exhibiting dark plumes and associated fan-shaped deposits during the local defrosting of the seasonal cap. We have documented the seasonal evolution of the cryptic region and have found that spiders only occur within this terrain. These observations are consistent with a geyser-like model for spider formation. Association with the transparent (cryptic) portion of the seasonal cap is consistent with basal sublimation and the resulting venting of CO2 gas. Also consistent with such venting is the observation of dark fan-shaped deposits apparently emanating from spider centers. Spiders are additionally confined to the polar layered deposits presumably due to the poorly consolidated and easily eroded nature of their upper surface.

A spectacular fossilised forest has transformed our understanding of the ecology of the Earth’s first rainforests. It is 300 million years old.
The forest is composed of a bizarre mixture of extinct plants: abundant club mosses, more than 40 metres high, towering over a sub-canopy of tree ferns, intermixed with shrubs and tree-sized horsetails. Nowhere elsewhere on the planet is it possible to (literally) walk through such an extensive swathe of Carboniferous rainforest.

Chlorophyll detected at Mars Pathfinder landing site?
(Apr. 3, 2002)

The Second Astrobiology Science Conference begins at NASA Ames Research Center on April 7 and surely one of the most intriguing announcements to be made is of the suggested possible detection of chlorophyll at the Mars Pathfinder landing site. These results, to be presented at the poster session by Carol Stoker and Pascal Ashwaden, both of NASA Ames, are summarized in the following abstract from the Conference proceedings:

The Superpan, an image product from the Pathfinder lander camera, is a multispectral panorama of the Pathfinder landing site acquired in 15 wavelengths in the spectral range 440-1100 nm. We have performed an automated search of the Superpan image cubes for the spectral signature associated with chlorophyll. First, images were calibrated to radiance values and then the multispectral images were co-registered to subpixel accuracy. An automated pixel-to-pixel search was performed on a 3-filter set of images (530 nm, 670 nm, 980 nm) to identify pixels where the following condition was met: 530 nm > 670 nm, and 980nm > 670 nm. Thus, we searched for the spectral signature associated with red light absorption by chlorophyll. When this case was met by the search routine, we plotted a full spectrum for the involved pixels and carefully examined the images. The condition was met for small areas in six image cases. All of these cases occur in near field images, where resolution is highest. Four of the cases occur on the spacecraft and appear to be associated with spacecraft structure. Two intriguing cases occur in small areas on the ground near the spacecraft.
