Phoenix Mars Pic

[wiz-oz]

Nasa is up to usual tricks posting first pics in black & white, then provides a colour image with thus rider:

This is an approximate-color image taken shortly after landing by the spacecraft's Surface Stereo Imager, inferred from two color filters, a violet, 450-nanometer filter and an infrared, 750-nanometer filter. See right hand image below:

Approximate to what?

My Bro got Nero to 'auto-adjust' the left hand pic colour and came up with this:

To me the left hand image now looks real and still has some reddish-brown patches and the rocks aren't washed out as in NASA composite. And, guess what we end up with blue sky - same as Earth.

I think the left hand one looks more realistic and even the computer program thinks so. But you wonder why they keep false colouring images - are they trying to project a particular paradigm of mars or fudged things to appear as if it is on a foreign body? Raises more questions than answers.

What's your opinion of the colour images?

ps: apologies for size of images. tries posting this earlier but couldn't find it posted, so sorry if this appears twice.

Wow, do you really feel that the
sky's blue on the 'red planet'...?

Maybe Nero's just 'used to' Terra norms,
and did the corrections based on that...?

Maybe Nasa got those pictures from the earth, right? ;)

[m1thr0s]

you know...we need to be careful what conspiracy theories we ascribe to. I have always felt that the only people who really benefit from the one that says the whole space program has been engineered in hollywood is the government itself...

cuz they really don't want people getting all excited about space migration at all. They only got into it for military reasons and have done everything in their power to impede its rational evolution...otherwise we would have had functional orbital habitats in operation already...

So before you sign on the dotted line, just ask yourself, who really benefits from this particular conspiracy rumor?

The Point I was making is that you can fudge the pics and present whatever you want. Doesn't make it right or wrong. But, depends upon what the agenda is because NASA is an extension of the Military and why would they bother to present a true picture anyway, except that they're using your tax $s. We don't get to see raw images, they're always false coloured towards the red end of the spectrum.

So you can call it what you like a theory, a conspiracy, or merely yanking the chain.

It was presented as a wake up call that what we're dished up needs to be viewed with decernment. But then we're all delusional anyway - so probably doesn't matter.

I was actually responding more to this comment:
Maybe Nasa got those pictures from the earth, right? ;)It is possible, of course...and a little skepticism is always a good thing. But it's unlikely that NASA would be behind any such fraud since NASA's budget has been cut to the bone over the last 4 administrations and part of this has been due to people having lost interest...part of it has to do with people not really believing any of it is even real.

I don't personally believe that NASA should be in bed with the government anyway but it's too late for that. SpaceshipOne has already demonstrated clearly that we don't need these multi-billion dollar powder kegs that NASA keeps cranking out...at least not to go to the moon and back safely...which they still can't even do with any degree of confidence.

None of this resolves the color issue though, so that's a mystery that needs more information to sort out. I don't understand how the atmosphere could be blue at all...maybe someone could explain that...

Hmm, as far as I can remember there are atleast star-pictures that hubble takes that can be downloaded in their raw form which can then be coloured as oneself wants to do it with a photoshop plugin specially coded for that kind of stuff, never tried it out but sounded quite neat. Though might be that they got somekind of 'mission' agenda on those mars pictures because it's 'special' and what not lol. NASA got alot of weird security stuff that for example ESA hasn't been that interested in scowling around about(remember when my father who is a space-physicist went to NASA for that stardust launch, all I can say that it appeared to be a friggin bad comedy show with all the elite security shit and what not :laugh: ). I think he wandered into the wrong room and they got flabbergasted by it and started to ask him out or something and he was more like 'wtf :D'.

Thanks Mythmath found the avatar by accident and thought a fresh look would be nice.


Here’s the ‘official’ reasons(excuses) for colours and they admit to guessing too:
http://marsrovers.nasa.gov/spotlight/spirit/a12_20040128.html
They've gone to a lot of trouble explaining it. But when you look below it doesn't make sense.

Now here’s a different version – extracted images and text:

Here’s the full document link:

http://www.hellasgr.com/PDF/NASA_NOT_telling_about_Mars.pdf

Look at the above images from Viking then go back to the ones I posted, notice something about the ground and the sky?

Changes the paradigm doesn't it if correct. An atmosphere on Mars - but they already know this, hence the excuses.
Like you guys I assummed it was pink/red, because it's the red planet and dust in the sky etc. But you can draw two conclusions about this - if it's blue then were the images in a Desert on Earth and the money hijacked for black ops? Or does it have an atmosphere of sorts which would support life. In which case I'd would keep it quiet to exploit what's there.

I'm sorry to say but if Mars had oxygen, it would be visible from telescopes from the earth as 'blue flecks' in the atmosphere, and it is clearly now so. As oxygen reflects blue light in all ways when photons hit it, it should be clearly visible.

[wiz-oz]

Amur, it isn't as clear as we think and of course more complex than we imagine.

"Surprisingly, such a simple detail as the colour of the sky on an alien world is far less than obvious. There are three reasons for this: incomplete knowledge concerning the workings of the human eye and the perception of colour, a very broad range of possible alien atmospheres, and of course simple lack of experience. Though the fundamental physical principals are all well known, their application is less than obvious. Mars' pink skies were a surprise when they were first seen."

Doesn't rule either option red-blue in or out. Too many variables. But the lesson is that we can't take things at face value.

moving this to science & technology folks...

Quite. We have to remember here of a number of things. Firstly -as you point out- the human eye is not the same as a robotic one working in an alien environment and projecting images across space. Secondly, the atmosphere on Mars is very thin, and the colouring of the sky varies according to the presence of dust at any given time as well as that of elements.

For example, on Mars sunsets and sunrises can colour the sky blue if there are enough of the relevant elements in the sky at the time, just as on Earth the sky can become red.

Still, I think it's fair enough to kick up a fuss about this. Not to disseminate conspiracy theories but rather to press NASA and ESA for a definitive answer (assuming they haven't already given one).

[Amur]

ESA is a bunch of beer drinking, good feasting space scientists definately not into conspiracies and if they would be on the conspiracy scale I bet their score would be way over the minus border just because they would be overly bored with the whole thing, like any decent scientist lol. Met most of them from ESA's Rosetta project over the years in their yearly meetings sometime as a kid lol. Was quite fun (except their meetings), which more or less wanted me to rip off my own arm and throw it back at them in an excessive explosion of boredom.

[m1thr0s]

yeah...I just think there's a deeper conspiracy that foots the government's needs to a tee...they want people to be as blasé as possible about the whole space exploration thing in my view...

how the hell would we protect anything on mars anyway? anything coming from earth headed that way is gonna be broadcasting its punches a good 5 years ahead of time!

but I still wanna know what the right colors are now...blue skies on mars would have to be telling us something important that we didn't already know I would think...
