Think about it. . .
Apollo program was dead in 1972. Missions canceled. The last few not even televised for the most part. The Russians wern't going there any time soon.
Only manned missions were to skylab to stay up with the Russian Mir program. Visions of "Star Wars" anti-missle programs & other satellite based intelligence gathering kept us interested in LEO missions, but exploring other celestial bodies was not seen as anything beneficial. This also included the Space Shuttle program.
Many future NASA space exploration projects that would needs billions in funding were on the drawing boards. ( Moon base, Mars mission, deep space probes, etc. ) Yet again, there was no dire need to beat the Russians to get there first because they were not going any time soon.
Could someone at NASA have seen the photos from Viking and envisioned a poster child/cash cow to generate the funding needed for their future endeavors in "the face"?
Any thoughts?

Well if that was the case we may probably presume that they would not have , to say nothing of the persisting effort, had to hide the evidence for it?

Hey thanx for your thoughts Stellar. Even though this thread was concentrating on the theory that NASA used it as disinfo-
I'm curious how you know the face is real? What evidence brought you to this conclusion? Thanx-

I believe the "Mars Face believers" have gotten (and some could say distorted) ALL of their evidence from NASA's Public information.
Can you show me actual data that NASA has covered-up regarding the face (or prove to me that data exists that has been covered-up)?
Most of the red Mars images resulted from using filters out of the range of human vision. Even recent rover panoramas and close-ups labeled “approximate true color” are made with infrared filters standing in for red. Olivier de Goursac, an imaging technician on the Viking Lander mission, argues that the glut of phony colors is easily avoidable. “NASA’s rovers have the capability for true-color imaging with the left camera eye, but they simply choose to use the L2 filter [infrared] as their red and the L7 filter [near-ultraviolet] for their blue,” he says. “They do this because they want to maximize the data stream by sending back to Earth images that can be readily used for stereo imaging with the widest possible range in the spectrum.”

Levin, a physicist now at Lockheed Martin in Phoenix, knew exactly how to tell if something was amiss. Two years earlier he had written a paper titled “Solving the Color-Calibration Problem of Martian Lander Images.” Like earlier Mars landers, each rover carries a color-calibration target—a set of primary-color squares used as a reference for its cameras. If the settings are correct the, squares seen through the rover’s cameras look about the same as matching squares on Earth. Levin tracked down Mars images that included a view of the colored squares, and what he saw confirmed his fears: “When the color-calibration target is in the same scene as the Martian surface and sky, it looks completely different. The blue panel is red. It’s as if NASA color-coded blue to be red, and green as a mustard-brown color.” The results dramatically transform Mars from an ocher planet to a red one.
The myth of a red Mars should have died in 1998, when the Pathfinder imaging team finished analyzing 17,050 images from the mission. The researchers conclusively showed that the predominant colors of Mars are yellowish brown, with only subtle variations. Subsequent “true color” images of Mars from Hubble duly show a yellow-brown planet. More recently, images from the European Space Agency’s Mars Express orbiter in January and February of 2004 present Mars as a world awash in browns, blues, golds, even olives—hence Ron Levin’s surprise and dismay at seeing the garish old red Mars resurface in the cutting-edge pictures from Spirit and Opportunity

The American space agency Nasa has been accused of doctoring its pictures of Mars to make the Martian surface conform to our impression of the famously red planet.
Nasa has been accused of digitally "tweaking" drab brown scenery to make it redder. It has even been suggested that Nasa removed green patches to hide evidence of life.
The theories gained credence after Nasa told New Scientist that "getting the colours right is a surprisingly difficult and subjective job", the magazine reports today.
Most of the pictures have been taken through green, blue and infra-red filters - instead of green, blue and standard red filters, which would have produced more accurate colours.
Dr Jim Bell, who worked with Nasa on the Mars rovers' cameras, said infrared filters were used because they helped geologists to distinguish rock types.
In reality, Mars appears red largely because of the dust in its atmosphere.

Maybe mars is no different - colours varying according to weather and light conditions?
If the Martian atmosphere were to be completely cleansed of dust, the daytime sky would appear blue, just as our own sky, because of Rayleigh scattering by the molecules (primarily carbon dioxide molecules) which make up the atmosphere. Pictures from the Hubble Space Telescope in the early 1990s suggested that the Martian atmosphere had much less dust loading than in the Viking years. So perhaps the Martian sky was closer to blue than in the Viking years(or perhaps the Hubble Space Telescope was inaccurate on this matter until repairs were completed in February 1997). However, Mars Pathfinder pictures in 1997 showed essentially the same sky color and dust loading as the Viking landers in 1976.

The first color image (12A006/001) of the surface of Mars was taken July 21, 1976, at the Viking 1 site, one day after the landing. Immediately displayed on color monitors at JPL, as seen in Figure 1a, the landscape awed observers with its resemblance to that of Arizona. Typical desert colorations of soil and rock, ranging from umber sand to yellowish-brown and olivine-colored rocks stood out clearly under a blue sky. Two hours later, however, the official image was changed to the monotone of orange-red (NASA P-17164), Figure 1b, that, with few exceptions, has prevailed in NASA-published images of Mars ever since, as presented by Mutch et al.[1]. However, a spectral analysis of color images of the Viking 1 site reported[2] a broader palate. The paper made the first, and perhaps only, reported use of JPL’s Image Processing Laboratory to analyze digitally the red, green and blue color channels of the images taken by the Viking 1 lander camera. In addition to studying the color images, their RGB components were transformed into saturation, hue and intensity components to enhance subtle deviations. When these components were equally amplified to produce an equal average sensitivity over the spectral bandpass, the resulting “radiometric” (closest possible approach in appearance to a human observer) images very closely resembled the first color image (12A006/001). Among the range of colors, the paper reported that some of the rocks exhibited greenish patterns that apparently changed between images taken 301 sols apart. Radiometric images of lichen-bearing terrestrial rocks taken and processed through the same system as were the Viking images showed a close resemblance of the lichen colonies to the greenish patches on the Mars rocks. Inclusion in the analysis of three near-IR channels available on the Martian images enhanced the greenness of the patches that were, to the sensitivity of the method, virtually indistinguishable from the lichen colonies on the terrestrial rocks.

Of course, the other problem is how do you calibrate the cameras to show true colour when you only have the images from the cameras to tell you what true colour is?
In other words it's possible all the pictures are correct - or, indeed, none of them.
The answer is that the color chips on the sundial have different colors in the near-infrared range of Pancam filters. For example, the blue chip is dark near 600 nm, where humans see red light, but is especially bright at 750 nm, which is used as "red" for many Pancam images. So it appears pink in RGB composites. We chose the pigments for the chips on purpose this way, so they could provide different patterns of brightnesses regardless of which filters we used. The details of the colors of the pigments are published in a paper I wrote in the December issue of the Journal of Geophysical Research (Planets), in case you want more details...
