Hort;

The only weirdness is that the official NASA colours of mars might have been exposed for what they really are, artistic unreal impositions.

This is really something. And the mushroom (like) surfaces IS facing toward the Sun. Hope the Martian Mushroom Surveillance Guys will not tamper too much with the "raw" data we have available.

maybe,,,,,,green berries instead of fields of blueberries?

Hopefully soon we shall know.

Maybe the MSL team should ask Dr. Stoker for her method of chlorophyll scan from the Pathfinder mission - just in case. Very Happy

Please pardon the Unscientific above observation.

Emotion has no place in science,,yet when I see green in the distant mountains,,on another planet,,,never before seen by any human eyes,,the sheer majesty of the moment almost overwhelms me.


This old man has seen SO many miracles come
to fulfillment by the hands of rigorous disinclined science,,,still,,to have lived in this moment,,,to witness the greatness of
puny human effort,makes me feel humble, but
oh so proud,,,and finally at a loss for words to describe this reality.

Thank You for allowing me,,to thank all of you.

Just a memory. When looking at these pictures, i have to think about the time (some years ago) that some pictures of the mars rovers were said ( a forum member here) to have rocks with Fin like appearances in them. The interaction between all kinds of materials that ultamitly formed plants, trees and life, seems to be happening There. Fins. Amazing. Goodnight from me.

Two more images from Curi's latest releases, initially processed by DX (Thanks DX) and auto white balanced in gimp by me.

LOts of greenery in the mountain.

Lots of whitish rocks, with partial green surfaces:

Note also the rover tracks, crisp and well defined.

In the last image above. The nearest foreground rock has some eroded surfaces that look suspiciously like drip erosion. There are also a few smooth looking shell like rocks.

I hope the above link works. It is a google translation from the Finnish of a news release from the Finnish Meteorological Institute, which provided some of the MSL weather sensors. It gives temperature and pressure data but says the humidity data have not been validated yet. The Finnish institute might be a source for future updates.

Horton, I have a question. Since each element of the Bayer Pattern Filter CCD array is covered with a filter, is possible to obtain monochrome image with maximum resolution offered by camera optics? Is the resolution will always be limited to half of that, which would we have using the classic CCD ?

Barsoomer;

Thanks for the info re. the Finnish Met Institute. The question is validation of data, not yet malfunctioning of instrument?

I used my own program, but I'm not satisfied.

Thanks Barsoomer for the MET info.
The water vapor content by previous Mars missions in absolute terms was only in the range of .03%. So 8% would be well outside the expected range:

Robert Clark; re your reply #373;

The questions therefore would be:-
Which figures were accurate?
Could both be accurate?
Could the earlier figures reflect humidity realities in the environments in which they were taken?
Could the new Gale crater figures reflect reality within a crater perhaps two miles below the normal martian surface datum?
Can Curi, by fairly easy experimentation, as it climbs sharp mountain, validate or correct the results?
Could the new figures offer a better explanation for the "mud" sporadically seen in MER images?
Could the new figures suggest a better rationale for what might appear to be anomalies related to type of erosion seen in many surfaces on mars by previous rovers?

That last image (closeup of the rocks) is awesome.

Thanks Winston for your kind comment in your 367, but if it wasn't for 'h' I could have been working on those images for years!!!

Winston ,,I do hope to see some commentary on your 374,,such good questions and dx your pictures speak for themselves and are increasingly higher quality.

I still remain slightly stunned (for need of a better word),,,at the distant green on Mt. Sharp.

Possible mineral related?
If so,,then what mineral?,,as stupid as it might sound the thought comes to me of the green related to copper decay from electrolysis in a high salt bath.
Duh?

OK, I have been busy this AM trying to get 10 pounds out of that 5 pound bag...


First, it is possible to get full size pictures from the raw Bayer data - but it involves choosing an interpolation scheme.

Here is a nice paper ( don't let the paper name fool you ) explaining the math of some of the more common schemes - and here is a site with practical tests of the effect of the various interpolation methods.

I picked one of the simpler ( bi-linear intepretation ) and added it to my Bayer-RGB macro.

If anyone is interested I will post in the imagej topic.


I also downloaded a sample raw Bayer test pattern and discovered that the sample test pattern was for a Bayer pattern beginning with a Green cell rather than Red cell - but after a simple shift in the pattern the resulting RGB image was as expected.

I am still trying a few tricks to get rid of the grids - but I suspect the only solution is to hope NASA sees the error of their ways ( after all they are NASA - and they know it ) and provide a PNG or GIF version of the raw files.


Er, PAM how did you get minimize the scan lines? I would like to try it in my macro.

Thank you very much for your encouraging comment-But as I said to Winston, 'h' is the headman for my interpretations.

WOW. You want to pursue more indepth programming to remove the grids, does this include the 'green' levels?

Also, thanks for the read on 'Bayer'.

Some random thoughts.

Olivine is a green mineral, and it seems likely that there is olivine in some places on Mount Sharp.

An absolute humidity of 8% corresponds to a frost point of about -30 Celsius on Mars. Since we have seen frost at the Opportunity site, it is plausible that the locaL humidity may reach that level at some times in some places, especially during the change of seasons when H2O is moving from one polar cap to the other.

The description of the humidity sensor says it measures relative humidity, but since that would vary with temperature in the day-night cycle, I presume the intention was to convert that to absolute humidity in order to present a relatively stable figure.
