Odyssey's Themis imaging
#1
Don't forget about Odyssey! It's Themis imaging system takes some marvellous and plentiful images in Vis and IR.

You may find this graphic data search page more utilitarian,
You can access the clickmaps from here

These are some of the things I've done with their data

Excellent!
I prefer its images to those of Mars Express, at least they (Themis) release their data

Keith, I personally think that the color images of Themis are close to correct! In many cases, greens really are greens and thus show plantlife and/or cyanobacteria-like organisms. Remember how Nasa reddened the skies of Mars? Well, that's why they are calling the RGB pics, "false color" when they are very close to true color, much of the time.

yeah, they're always dinking with the filters.

Huh....False colour...and the Face has a false moustache and the
vegetation jumps on the camera lens and has to be wiped off...
...but they don't tell you that....anyway...

I've been loading the themis images into the Gimp using the pds
plugin which handily arranges the bands for you into the right
RGB layers....cool.

But, I've tried the EDR and EDR d/l's for V12445004, and now there's
another: 'geometrically projected' (GEO) but this image does'nt
have that.

I always get these segmented bands and although I can hand align
parts of the image it does'nt look too good.

I'm missing a whole technique here, are'nt I !

Mars Reconnaissance Orbiter has a rebated camera! There is NO blue filter, along with the green, red and IR filters to make true color pics. The 321 pics of Themis are the most accurate of all. Those Nasa thugs are pigs for rebating that main camera like that!!!

Keith, I have seen your reproductions of the 321 Themis color pics...well done, but the colors are not right. Mars is not that red and there is life on it as well. Your ground photos are great though. Mars has a light blue sky due to a heavy atmosphere...Nasa lied about the thickness and the composition of Mars' atmosphere. It could be breathed...but the life forms there might be dangerous to us. Hmmm...I wonder if any life-forms can be eaten on Mars?

Opportunity is thriving on the stuff!

This is a recently posted photo from:
[Image: PIA03622_modest.jpg]

http://photojournal.jpl.nasa.gov/catalog/PIA03622

And this is a report by Joseph Skipper about it:

http://www.marsanomalyresearch.com/evid ... dcover.htm

Interesting issues here, which contribute to Xuxa’s comments and “Hidden Mission” matters.

I’m interested in “agriculture” evidence and I came across the Photo Journal image sometime over Christmas, but apart from thinking “strange textured dust?” I never made the connection as in JS’s report. Until then I was looking more for larger size growth. But now “ground cover” such as this will be on my “watch out for” list, and I will look much more closely at images from this site in future too.

An area like this should be easily capable of analysis for chlorophyll. Anyone know of any undertaken and Xuxa do you have links to chlorophyll reports?

Keith, any chance of putting your colour imaging skills on this one?

You may be interested (or not) in another websites observation of Rover image manipulation Orpbit2.
The images are similar to the one you posted abobe albeit in Black and white.

I was down at the library today, so had a good look at all the images I could find re my last post, including revisiting all of Keith's Opportunity images, with a more specific search focus.

I think I will stick with my original interpretation of "strange textured dust", although the dust is clearly more "gritty" in nature. That's not to say that some colouration could be due to living organisms of some kind, but if it is then clearly of a more "micro" plant nature than "macro".

I find the whole scene very reminiscent of my time working in Wales where I was involved in a lot of reclamation issues on active coal spoil tips, and many disused lead mines.

If I were just given the images to comment on with no info as to where the location was, I could quite easily interpret the area as an old mining field with spoil tip material spread over the area through decades of erosion and wind scouring. The presence of so many artefacts of a machinery nature could be indicative of buried defunct machinery now becoming exposed along with remnants perhaps of demolished/abandoned buildings.

Alternatively, it may have been the site of a huge power plant complex with clinker and the Martian equivalent of "Pulverised Fuel Ash" spread all over the area partly by the hands of intelligence and then modified again by decades (if not centuries) of weathering and other natural forces.

Of course this is all speculation, but I am happy now that I hadn't missed, in my "quick search"mode, evidence of macro plant life, even if only of ground cover proportions....unless anyone else wants to debate otherwise?

Is this JPL posted image one of yours Keith?

Hi Beagle2...obviously crossed posts!

Yes I would be interested so if you have the link please supply. I might have been there already but it might also be of interest to others.

(Good to see the Toffees creeping up again!! Love the "friendly" rivalry in the area....don't think much of Gary Neville's antics though....gives us Brits a bad image....as if we haven't already Cheers

Thanks!

And how are you getting on with Comb2?

Beagle2.

Followed up the link! Lots of images although difficult to wade through. Could do with having thumbnail pages of say 50 at a time!

Unfortunately, even when choosing the English language button, most text still comes out in Italian...

a case of WTFDTM! Cheers

It has a blue-green, a red and a near infrared filter...but what it needs for accurate color imaging is a blue, a green and a red filter. The colors will be very distorted due to the deliberate non inclusion of a true blue filter and a true green filter along with the red filter. This crap is exactly what I predicted...just like the MOC camera!
