Colors of Mars

http://mikebara.blogspot.ro/2008/01/revisting-true-colors-of-mars.html





Dr. Gil Levin's first-hand recollections of the whole affair are recounted in a recent
book by science writer Barry DiGregorio. In the book, Levin relates the remarkable
overreaction by JPL that occurred in response to Ron Levin's naive efforts to "correct"
what seemed to him to be a deliberate distortion of the incoming Viking Lander data.
According to DiGregorio's narrative:

"At about 2:00 p.m. PDT, the first color image from the surface of another Planet,
Mars, began to emerge on the JPL color video monitors located in many of the
surrounding buildings, specifically set up for JPL employees and media Personnel to view
the Viking images. Gil and Ron Levin sat in the main control room where dozens of video monitors and anxious technicians waited to see this historic first color picture. As the image developed on the monitors, the crowd of scientists, technicians and media reacted enthusiastically to a scene that would be absolutely unforgettable — Mars in color. The image showed an Arizona-like landscape: blue sky, brownish-red desert soil and gray rocks with green splotches.

"Gil Levin commented to Patricia Straat (his co-investigator) and his son Ron, 'Look at that image! It looks like Arizona'" (see photo above).

"Two hours after the first color image appeared on the monitors, a technician abruptly changed the image from the light-blue sky and Arizona-like landscape to a uniform orange-red sky and landscape. Ron Levin looked in disbelief as the technician  went from monitor to monitor making the change. Minutes later, Ron followed him,  resetting the colors to their original appearance. Levin and Straat were interrupted when they heard someone being chastised. It was Ron Levin being chewed out by the Viking project director himself, James S. Martin, Jr. Gil Levin immediately inquired as to what was going on. Martin had caught Ron changing all the color monitors back to their original settings. He warned Ron that if he tried something like that again, he'd be thrown out of JPL for good. The director then asked a TRW engineer assisting the Biology team,  Ron Gilje, to follow Ron Levin around to every color monitor and change it back to the red landscape. "What Gil Levin, Ron and Patricia Straat did not know (even to this writing) is that the order to change the colors came directly from the NASA administrator himself. Dr. James Fletcher. Months later, Gil Levin sought out the JPL Viking imaging team technician who actually made the changes and asked why it was done. The technician responded that he had instructions from the Viking imaging team that the Mars sky and landscape should be red and went around to all the monitors, "tweaking" them to make it so. Gil Levin said, "The new settings showed the American flag (painted on the Landers) as having purple stripes. The technician said that the Mars atmosphere made the flag appear that way [emphasis added]."

It turns out that DiGregorio's statement that the NASA administrator was behind the
monitor changing incident was based on a confirmation of this from an official source —
former JPL public affairs officer Jurrie J. Van der Woude — and it had an even stranger
and somewhat sinister angle: In a letter to DiGregorio (also reproduced in Mars: The
Living Planet), Van der Woude wrote:

"Both Ron Wichelman [of JPL's Image Processing laboratory (IPL)] and I were responsible for the color quality control of the Viking Lander photographs, and Dr. Thomas Mutch, the Viking Imaging Team leader, told us that he got a call from the NASA Administrator asking that we destroy the Mars blue sky negative created from the original digital data."

This bizarre sequence of events raises many disturbing questions. For instance, why
was the administrator of NASA so determined to conceal the "true" colors of Mars from
the American people and the world in 1976? Why would he order the head of the Viking
Imaging Team to literally eliminate an important piece of historical evidence from the
official mission archive — the original "blue-sky negative" — if the initial release was only
an honest technical mistake? Wouldn't that record be an important part of the ultimate,
triumphant story of NASA scientists correcting initial scientific errors, in their continued
exploration of the frontier and alien environment of another world? And why would a
young teenager (the son of one of the key investigators on the Viking mission, no less) be threatened with expulsion by the director of the project for simply tweaking a couple of color monitors around the lab?

You seem to have left out an important detail of how they got their image of "reality".
"when we used a simple color correction tool in PhotoShop called the Auto Levels tool" That makes it quite clear that it is not reality and instead is photo with the colour altered.
This relates to a fundamental issue with all cameras and colours, that of white balance. A simple colour correction tool will try to have what it deems to be an appropriate white balance.
If the image is naturally red for any reason and you apply such a simple tool, it will ignore that and think it is a colour correction issue. This means it will adjust away the red.

It isn't surprising that applying filters based upon images from Earth will produces images like those from Earth.

The article also uses a lot of circular reasoning.

And some quotes make no sense.
There is no negative for a digital image.
A negative is produced as part of an analogue photography process.
This does not happen with a digital photo.

I can also find no valid references for these quotes/claims. All I find are from conspiracy websites repeating the same claims.

Sorry, if I'm straying from your topic Sandokhan, but this came to mind and is interesting.
Apologies for the lengthiness.

Regarding color changes in early telescopic views of Mars attributed to vegetaion along extensive canal network:

Excerpts from the book "Supressed Inventions and Other Discoveries" by Johnathan Eisen
Article: "Mars - The Telescopic Evidence" by Daniel Ross

"The problem with all planetary research and common speculation to
date, must be defined here at the beginning. It is this: Official presenta-
tions regarding planetary space conditions have been made to coincide
with (complement) the long standing suppression, and censorship, of the
real UFO evidence by our government. This is why the truth about Mars
has never been known, publicized, or accepted, up to the present."

"The early history of telescopic observation of Mars has been recounted
in numerous books. It began in 1877, when Giovanni Schiaparelli
observed through his 8.75 inch reflecting telescope, a number of long
lines on the Martian surface that connected up to larger dark areas. He
described the lines as "canali," which in his native language meant chan-
nels. But the translation quickly became "canals," and his discovery of
them led to the idea that intelligent beings on Mars must have construct-
ed artificial waterways. While Schiaparelli didn't publicly suggest that
conclusion himself, he didn't really discourage others who were promot-
ing the idea, because he had found 113 different canali that were long,
straight, and neatly defined. He intricately mapped the planet from years
of observation. His maps were the standard for many years, and he gave
ancient names from Biblical and classical mythology, along with names
from the old geography of the Middle East, to the large surface areas and
distinct markings of the planet. The names he gave to the surface features
are still existent on maps today. "

"A distinguished American astronomer, Percival Lowell, decided to ded-
icate his life to studying Mars. In 1894, he built the Flagstaff Observatory
in Arizona, which housed a 24-inch refracting telescope. By 1915, he and
his staff had charted nearly 700 canals — a precise network of large-scale
construction on Mars that channeled water from the polar ice caps. They
were straight, narrow, sometimes parallel, and at numerous locations the
canals intersected geometrically. These latter areas Were noted to become
seasonally dark, and Lowell named them oases, indicating that vegetation
and crop growing were abundant. He naturally concluded that there would
be attendant cities for the Martian people at these oases.

Lowell understood that the actual waterways could not be seen from
Earth, if it were not for the broad areas of seasonal growth lining both
sides. It was the combination of both factors that made it possible to see
the network of geometric lines on Mars' surface with clarity. Some of the
channels wei;e approximately 3000 miles long, and from 15 to 25 miles
wide."

"To view the extensive canals and markings, an astronomer had to
have unlimited patience and determination, and more importantly, an open
mind. Like the establishment scientists today, Lowell's contemporaries
often lacked such traits."

"Ever so momentarily,
our atmospheric unsteadiness will cease for a second or two. At that pre-
cise moment an astute telescopic observer will have a perfect seeing con-
dition, and be able to see in fine detail the planetary image 35 million
miles away."

"Lowell made a special expedition to Chile in 1907 and obtained the
first photographic evidence of the canals. His successor, Dr. E. C. Slipher,
had better success in later years with observations from South Africa,
when camera equipment had improved considerably. The Martian canals
are seen on plates VI and XLVH in the book, The Photographic Story of
Mars, by E. C. Slipher."

"Dr. Slipher stated in 1962, "The history of the canal
problem shows that every skilled observer who goes to the best available
site for his observations has had no great difficulty of seeing and con-
vincing himself of the reality of the canals. I am not aware of a single
exception to this." A fellow astronomer, Dr. Pettit, confirmed this visual
documentation, by reporting in 1953 that "there are moments when the
whole canal pattern can be seen on Mars."

"Today's literature never fails to mention that the early Mariner probes
during the 1960's proved that the canals are non-existent, and that the con-
troversy over the Schiaparelli and Lowell evidence has been laid to rest.
It is true that no actual evidence of canals was released by NASA, but it
should be realized, that if the picture-taking cameras on those early probes
did photograph certain areas showing canals with sufficient clarity, the
evidence would not have been released anyway."

"The early photographs showing the Martian atmosphere were taken by
G. E. Hale of the Mount Palomar Observatory [Southern California] and are
reproduced in Nelson's book. There are two immediate and important con-
clusions that can be drawn from these observations. The surface gravity on
Mars must be substantially higher than has been taught, for a low gravity
would not be sufficient to retain such a sizable atmosphere. Secondly, with
such a dense atmosphere, the sun's energy would interact much differently
than orthodox theories suggested, and the temperatures on Mars would be
considerably warmer, more moderate, and more Earth-like."

"Both the northern and southern polar caps extend nearly half way to the
Martian equator during their respective winters. With the onset of spring
in either hemisphere, its ice cap recedes and a wave of darkening over
broad areas spreads slowly towards the equator. This cyclic surface dark-
ening was widely considered to be seasonal vegetation growth as water
was liberated from the polar caps. Each polar cap will shrink considerably
during its respective summer cycle. Sometimes the southern polar cap
melts completely. "

"The broad areas near the equator, such as Mare Serpentis, Mare
Sirenium, and Syrtis Major, change from their winter shade of brown, to
light green and then to dark green. This latter stage has often been
described as a dark blue-green. Astronomers also noted that as the seasons
changed to autumn, the colors would gradually turn to yellow and gold,
finally returning to brown in winter. "

"During the November 1958 opposition, Dr. William Sinton conduct-
ed studies at the Smithsonian Astrophysical Observatory. The scientist-
astronomer performed careful infrared scans of the bright desert areas and
the dark green oases, and found that the sun's energy was absorbed in cer-
tain wavelengths over the dark areas, but not over the desert regions. The
absorption wavelengths were at 3.43, 3.56, and 3.67 microns*, and these
are exactly the same wavelengths absorbed by hydrocarbon compounds.
His study proved that there is green plant life on the broad oases of Mars,
and that it is organically composed of carbon-hydrogen compounds, the
same as our own terrestrial vegetation. In other words, his scientific evi-
dence showed that Martian plant life is based on the same carbon cycle as
we find on Earth."

It says that because the Viking missions were fake, sandokhan.

I’m not sure Mike Bara, the author of the blog you referenced, believes Mars rovers are fake or not. He believes we went to the Moon, but for secret reasons plus a whole bunch of stuff. I wouldn’t use him as a source for anything considering some of the wacky things he purports.

Mike Bara books:
"In Ancient Aliens and Secret Societies (2015), Bara claimed that NASA is run by mystics who worship Egyptian Gods, and the Agency times all launches according to astrological readings. He wrote "What I do know is that NASA continues to follow these rituals to this day, on virtually every mission they undertake.”

"Hidden Agenda: NASA and the Secret Space Program (2016)...One of Bara's principal themes was that the real secret purpose of Project Apollo was to retrieve the technology of the Anunnaki from the Moon.”

"Hidden Agenda (2016), Bara used an image from Lunar Reconnaissance Orbiter, showing a landslide down the rim of crater Marius, in the Ocean of Storms. But he turned it upside down and claimed it was a crystal tower.”
No. That sudden lurch forwards is the atmospheric slosh effect.

Regarding color variations, I found this quite informative:

"The first color image of Mars by the Viking 1 lander was assembled from red, green and blue 'scans' across the surroundings by a panoramic camera on the lander rotating like a periscope. As referenced in the NASA SP-425 'The Martian Landscape' page 27, the initial intention was of showing a noncommittal gray sky, as they were having trouble believing the overall reddish color bias and needed more time to commit themselves to a confident presentation of what the cameras were telling them…
For photos made on the surface with red, green and blue filters rotated before the camera optics, proper color balance generally makes the green image exposed as a decent representation of the relative gray tones in the scene, with the red channel overall lighter and the blue channel overall darker. Only the actual data released on the NASA PDS Imaging Node can be used with confidence to provide a view of what the cameras are showing us on Mars, not the preliminary inferior JPEG releases which are generously provided to give the public a quick look. The excellent Pancam true color images site provides the highest quality color images, prepared by the team most familiar with the camera characteristics.

The comparison of both preliminary and calibrated versions of the same images, generated with the preliminary JPEGs and from the real data, is a worthy exercise. The examples at left
(below) provide an example from Spirit's sol 149.



On top is a color image close to actual color values, with gray scale strips from each color channel making up the color image also shown. Note how the brightness changes across the spectrum correspond to trends measured from Earth and from Mars. The RGB gray scale comparison on the right follows the trends of the spectral measurements from Earth shown above, with the brightness and contrast of the surface materials increasing toward the red end of the spectrum.

Such absolute color channel intensity variations are not incorporated into the preliminary jpeg releases, as seen in the comparison jpeg derived version below. The actual brightness levels and contrast in the RGB color channels are discarded as automatic levels adjustments are made for fast releases of such data. Such 'auto contrast' treatment can optimize the range of brightness for individual frames by stretching the contrast levels but produce misleading color when simply combined as an RGB image. Martian skies and dark surface materials looking a garish blue are a frequent result of such efforts. In reality a dust free basaltic rock should appear a dark nearly neutral gray."

Well, fascinating, but is there an actual point to this?

Surely according to flat earthers these images are just lies and forgery and manipulation anyway.

Is JPL not firmly in cahoots with NASA?  Or are you saying that NASA was somehow keeping JPL in the dark about it all?

How exactly does this fit into the grand conspiracy theory?

Evidence?

Some explanation here:

https://www.nbcnews.com/science/space/color-controversies-started-mars-not-thedress-n314601

The different colours are simply attempts to process the data to show different things - they've shown the raw data, processed it to attempt to show what it would look like if you were standing there and what it would look like were it lit by earth-like sunlight - as in light filtered through our atmosphere, not Mars's.
But whatever tweaks your tin foil hat I guess.

Most satellites and other spacecraft don't carry conventional cameras. Many of the space images we get from NASA and others are actually not photographs.

Instead of photographic cameras they carry instruments which capture light in different wavelengths. The data is then sent to earth to be computer processed. The result is images in gray tones (like black and white). Three of these gray images are then assigned to the RGB colors to produce the color images we often find. A natural or “true-color” image combines actual measurements of red, green, and blue light. The result looks like the world as humans see it. A "false color"image uses infrared measurements, like for example the one in my avatar.

Each Viking lander carried two facsimile cameras like this one:

Each Viking Lander was equipped with two identical cameras that, unlike conventional cameras, did not use film. Instead, a moveable mirror scanned a vertical segment of the martian scene, and photodetectors recorded the amount of light reflected into the camera. A complete picture, or "image" of the surface was made by completing a vertical scan, and then rotating the camera slightly for the next scan. (https://airandspace.si.edu/collection-objects/camera-imager-viking-mars-lander)

I'm not sure how the Viking color images were exactly made though, it might differ to what modern satellites do. Here are some useful links:

This is really a really silly argument. And it shows so much ignorance.
First, here is a surprising fact that a lot of people will not know.

Mars has blue sunsets! NASA has published tons of pictures of it. So if they where hiding a blue sky, they did a shoddy job of it. Or maybe forgot they where supposed to doctoring their files?

Also, why is they guy changing the colour of the monitors?
The monitors dont change the colour of the source file, just what the monitor displays. It wont even print it differently.
Its like closing your eyes because you dont want to see the scary thing, the scary thing is still right there.

But the other question to the conspiracy is, why would they even bother with this.
Before they landed on Mars, there where no images of the sky from Mars.
If the sky was blue, just say, "oh look, its blue". Why would a red sky have legitimized the mars missions any more than a blue sky?

Hi everyone! The true colors on the images from Mars - not easy task. I had litlte investigation. The most significant results are:ri
 1) I know how to combine B/W images from Spirit to true color image correctly.
 2) The sky on Mars is blue.
 3) The sky on Mars is different colors. Some times it can be blue, some time - rose. I think it`s a dust.

They might have shown the wrong unfiltered footage of the untouched earth sky before realizing their mistake.

It might have also been a live feed from a viking robot on a desert somewhere, since the operators are supposed to be able to control the camera and some of the devices, with a 20 minute delay.

Even if it's really on Mars, that's still suspicious that they don't want people to see the blue sky. Whatever the case, systematically changing the monitors in the room is rather suspicious

Or they might have known there was a large amount of uncertainty in the colour balance, as explained above, and the project director didn’t want to give the “wrong” impression to the reporters in the room.  At most that would be an overreaction from someone thinking a bit too much about PR.

Far more likely than them filming in the desert and nobody thought about the sky being the wrong colour.  Unless standards slipped massively since the alleged fake moon images?

As opposed to if they had faked it, where they would have produced the images already being red.

It requires them to be extremely competent to pull of such a hoax, yet easily fail at a very simple hurdle.

It makes no sense at all.

White balance is far more likely going to be the issue, and someone wanted the images to appear as they would have if you were on Mars.

So, according to you there really was a lander on Mars. The colors came in all wrong due to some technical glitch. This technical glitch causing the wrong colors made the United States flag on the craft look red, white and blue. NASA then decided that the colors were wrong and adjusted all of the monitors, causing the witness present to remark "The new settings showed the American flag (painted on the Landers) as having purple stripes."

An interesting series of events.

That comes from a book called Dark Mission: The Secret History of NASA, which was copied (plagiarized?) for another book called Ancient Aliens on Mars.

Both books firmly establish both Earth and Mars as round planets, both orbiting the Sun millions of miles away.  So their claims are probably just part of a massive, multi-generational, multi-national, world-wide conspiracy of disinformation and confusion to distract from the foundational truth of the shape of the Earth.

Best ignored, really.

Do you have evidence for your claims. Sandokhan seems to get his photos from conspiracy sites such as this one:
Quote
Mars - Now Has Life And A Blue Sky
The purpose of these files is to report the UFO eyewitness and photo/video evidence that occurs on a daily basis around the world and in space. Moon and Mars - Exploration to Continue, Mars - The Veil Over the Martian Sky May Be Lifting, Mars Sky Is Really Blue and Rocks Have Green Algae, Mars - Is the Speck in the Mars Sky a UFO?
Weird!

But what colour would you expect the blue of the American flag to have when viewed under a reddish light? It would seem that "having purple stripes" would be expected.

Oh, hell, I watched it live.

They spun some knobs and dialed in a blue sky during tune up.
Then they pointed the camera at a color target.

OH, SHIT!

Calibrate the instruments . . . . . huh, orange.


I know, St. Thomas Aquinas warned about this.

But what colour would you expect the blue of the American flag to have when viewed under a reddish light? It would seem that "having purple stripes" would be expected.

It is implied that the flag originally came in with its correct colors and was turned purple with the new settings. Coincidence?

Coincidence? Perhaps. Though seems like a pretty thin thread to hang all of Mars probe/rover missions were simply shot in an Arizonian high desert. Logic dictates we need something more as the complexity in camera tech, in the supposed environment, under the supposed circumstances/conditions warrant a much more thorough review rather than than just "the sky is blue" in one jpeg versus "the sky is red" in another.
No. That sudden lurch forwards is the atmospheric slosh effect.

Hanging your hat on a coincidence sounds like the "thin thread" to me.

Well, you hang your whole model on coincidences and unsupported hypotheses sounds like the "thin thread" to me.

But there's not a lot that I do if you will not believe that there was a need for calibration using a Z-test chart.

First colour image from Viking Lander 1. This color picture of Mars was taken July 21 1976 -- the day following Viking l's successful landing on the planet.
The local time on Mars is approximately noon. The view is southeast from the Viking. Orange- red surface materials cover most of the surface, apparently forming a thin veneer over darker bedrock exposed in patches, as in the lower right.
The reddish surface materials may be limonite (hydrated ferric oxide). Such weathering products form on Earth in the presence of water and an oxidizing atmosphere. The sky has a reddish cast, probably due to scattering and reflection from reddish sediment suspended in the lower atmosphere.
The scene was scanned three times by the spacecraft's camera number 2, through a different color filter each time. To assist in balancing the colors, a second picture was taken of z test chart mounted on the rear of the spacecraft. Color data for these patches were adjusted until the patches were an appropriate color of gray. The same calibration was then used for the entire scene.

They might have shown the wrong unfiltered footage of the untouched earth sky before realizing their mistake.

It might have also been a live feed from a viking robot on a desert somewhere, since the operators are supposed to be able to control the camera and some of the devices, with a 20 minute delay.

Even if it's really on Mars, that's still suspicious that they don't want people to see the blue sky. Whatever the case, systematically changing the monitors in the room is rather suspicious

Or they might have known there was a large amount of uncertainty in the colour balance, as explained above, and the project director didn’t want to give the “wrong” impression to the reporters in the room.  At most that would be an overreaction from someone thinking a bit too much about PR.

Far more likely than them filming in the desert and nobody thought about the sky being the wrong colour.  Unless standards slipped massively since the alleged fake moon images?

So, according to you there really was a lander on Mars.

I didn’t say that.  Only that your version is mere speculation.  If someone produces any real evidence, whistleblowers, leaked documents, etc. to show it was faked, I might take it more seriously.  Same applies to other claims of space fakery.  It’s all so weak.

The colors came in all wrong due to some technical glitch.

Correction- technical limitations, not a glitch.

Colour balance was a known uncertainty on Viking and is still an issue with probes and rovers today   There are plenty of scientific papers dedicated to analyzing the results, such as:

Introduction

Since the Viking Lander sent its first color images in August of 1976, there has been a great deal of difficulty producing color images with a consistent color balance. For the first several hours, the images were shown to have a blue sky with some greenish areas on rocks. After that, a major recalibration was performed, which rendered these Viking images in a much redder tone with a red or pink sky, and the green areas replaced with gray. Several hours after that, the images were recalibrated again with the sky moving toward a more neutral pink, the areas on the rocks remaining grayish.

A roundup of subsequent published Martian lander images has shown a wide variety of scene colorations.  Official published images from Viking, Pathfinder, and, more recently, Mars Exploration Rover (MER), continue to show wide variations of color. The builders of the Viking, Spirit, and Opportunity landers provided two methods for calibrating the color response of Martian imaging.

The first method was a derivation of color calibration algorithms using the flight cameras while still on Earth before launch. The actual flight cameras were used to take images on Earth, which were then used to develop color calibration algorithms. These algorithms were tested repeatedly and found to produce reliable color imaging while the spacecraft were still on Earth. These calibration algorithms were then stored for use with the digital data transmitted from Mars. This method of calibration relies on the assumption of stability of the camera instrument during the transit from Earth to Mars.

The other method of color calibration depended on the observation of color calibration charts onboard each of the landers as illuminated by ambient Martian sunlight and skylight. While this technique does not require any assumption of stability of the flight camera during its transit, it does require that assumptions be made about the color of the light with which the color charts are illuminated. Both Viking and MER rovers carried these charts. Current scientific opinion holds that the color charts and the Martian surface are illuminated in a very red light caused by large amounts of red dust in the atmosphere. The exact effect of this red dust is not currently known and is often cited as one reason why there is so much variation in color.

This technical glitch uncertainty causing the wrong colors made the United States flag on the craft look red, white and blue. NASA then decided that the colors were wrong and adjusted all of the monitors, causing the witness present to remark "The new settings showed the American flag (painted on the Landers) as having purple stripes."

An interesting series of events.

So?  Seems reasonable for the flag’s colours to look different in the Martian atmosphere compared to Earth’s atmosphere, even before taking into account  any uncertainty in the colour balance.

If I google “US flag flying”, I see a fair amount of colour variation in images.  Sometimes the red is scarlet, sometimes it’s deeper, occasionally a bit pink or purple.  That’s just with different cameras and different lighting conditions on Earth. Bare in mind that professional photos will no doubt have been adjusted to look good as well.

You have a single source saying they thought the flag looked better before the image was adjusted.  So conspiracy?  Seriously?

You’ll also note I never claimed that the adjusted image was more correct than the original.  Only that someone thought it was, and  might have been wrong.

However, the above paper says there was an actual recalibration involved, not just changing the monitor settings.  Maybe that’s two separate events?  Maybe the story in the OP is incorrect?  I don’t know.

I take it you don't understand how the colour of the light source influences the apparent colour of an object?

Here is a simple one for you:
If you had a white sheet of paper, but illuminated it with red light, what colour would it appear?
White or red, or something else?

Could someone tell me what the link is between what the colour of the sky or surface on Mars is and whether the Earth is flat or not. With a little bit of simple editing in Photoshop you can make the surface of Mars look like Earth and vice versa.  So what's the point here?
