NASA press release today, regarding the Martian meteorite Yamato 000593 (Y000593):
"The team reports that newly discovered different structures and compositional features within the larger Yamato meteorite suggest biological processes might have been at work on Mars hundreds of millions of years ago."
"The observed micro-tunnels display curved, undulating shapes consistent with bio-alteration textures observed in terrestrial basaltic glasses, previously reported by researchers who study interactions of bacteria with basaltic materials on Earth."
"The second set of features consists of nanometer- to-micrometer-sized spherules that are sandwiched between layers within the rock and are distinct from carbonate and the underlying silicate layer. Similar spherical features have been previously seen in the Martian meteorite Nakhla that fell in 1911 in Egypt. Composition measurements of the Y000593 spherules show that they are significantly enriched in carbon compared to the nearby surrounding iddingsite layers."posted by Paul Scott Anderson at 12:16 AM EDT | Discussion (2)
Hey there I'm putting together a curiosity image explorer using the wonderful MSL json feed.
The intention is to allow crowd-source tagging of interesting parts of images.
code is all on github at https://github.com/open768/curiosity_browser
the evolving protoype is here: (works in chrome) http://www.mars-tourist-guide.co.uk/curiosity/
happy to take suggestions from this forumposted by open768 at 6:19 PM EDT | Discussion (3)
Some of the challenges looking for early life on Mars when we have no idea if there was life there, or where it originated, or what type of life it was or what type of habitat it was in - go into details about some of the places we might find it, and chances of preservation of life from billions of years ago.
It's quite topical as the deadline for suggestions for candidates for ExoMars is 28th February - though because of limitations on what it can target, seems most are ruled out except Mawrth Vallis for ExoMars.
Anyway - interested in anything any of you say (and thanks for the discussion of my earlier article on Science20 here)posted by Robert Walker at 8:19 AM EDT | Discussion (7)
My presence here is limited because of periodic obsession. Targeted writings to promote this blog have been ongoing. this has also allowed me to focus my understanding.
This article is a reflection of what has been learned. Does it have a perceptual slant? I suppose but the visible date must not be ignored.
It would be impossible to thank all of you for your input. I am still waiting for Winston's breakout. I am sure it will come.
I could not use some images because of there were no creative commons license. I was able to sneak them in with the YouTube video.
Article link below.
Hort you can make it user friendly....

I am intruiged by some rocks in rocks on the right in the the valley viewed from Sol528. Is it possible to get a closer look at them as Curiosity is in the area.
the original image is http://mars.nasa.gov/msl/multimedia/raw/?rawid=0528ML2087006000E1_DXXX&s=528
The rock in question has some features that are very reminiscent of a half buried humanoid from the angle it was taken.
But many a rock has fooled us citizen scientists as viewed from different angles the rock de-resolves into just rocks. So a diferent perspective is definitely needed before claiming fantastic finds
I'm genuinely both personally and professionally interested in the processes that might have gone into creating this rock.
Professionally I work on the technical aspects of EO PDGS.
I was just looking through the latest NASA photograph from the Mars Rover and saw a rock which seems to depict a head of a statue buried in the sand. Have a look for yourself and see what I mean.
Go to the Nasa photo here:
The go to the right hand side of the image, about half way down from the top. Go into close up and you can see it for yourself.
If you click here you can see the head as a separate graphic:
I'm not saying it is a statue of course - just that it looks a lot like one.
