Did you know Mars is NOT reddish in color? It’s true. It looks just like earth!!! Mars has earth colored soil and a beautiful blue sky – just like Hawaii!
I know this because it says so on this conspiracy website:
«This is very interesting. It may come as a surprise to many readers that Mars looks very much like Earth. It’s not red or orange – NASA applies a lens to tint the pictures or they release black and white photos… here’s a real color picture of Mars… blue sky and all… it gets to the point where you ask yourself “what does the government not lie about?”»
They included this image as proof:
I can’t believe anybody would believe Mars looks like earth. But i’ll push forward simply for the entertainment value and because there is some interesting facts to be learned – stuff i didn’t know. I love everything space related.
Two facts about Mars:
So while the Romans and the Egyptians knew Mars appeared red simply by looking up into the night sky, today’s conspiracists insist our belief that Mars is red is actually a false belief perpetuated by a government coverup.
Maybe i am endowed with an abundance of common sense but couldn’t these conspiracists step outside their mother’s basement, look up into the night sky and see what Mars looks like to the naked eye? I’m just saying.
But i digress …
So i decided to pursue this absurdity to another level. I took the photo featured on the conspiracy website and i decided to find out where it came from. I found the original photo at the NASA website. It really wasn’t hard to find (Even a conspiracist could have found it). I then superimposed the conspiracy picture next to the original NASA photo. The conspiracy photo is on the left, the original NASA image is on the right:I added the phrases “False Color” and “True Color” to the above image because these are two terms used by NASA to describe how they color correct photos taken by their landers and satellites. They have good reasons for making different color corrections to their photos, but first, let’s understand how NASA calibrates the colors in these Mars photos:
This is the same process used by Hollywood movie makers. They use a device called a “clapper board” to mark the beginning of a scene or a “take.” I’m sure you’ve seen this used in the movies. Well, at the top of some clapper boards you will see a rainbow of colors. Like the Pancam calibration target on the Mars rover, the colors along the top of the clapper board provide a known color reference that can be used in post production by movie editors to ensure the colors in the final cut are “true” to what was recorded on the movie set.
Speaking of “true colors,” let’s get back to why NASA would choose to creat “false color” photos along with “true color” photos. It’s really not as mysterious as it might sound. Let’s start with a technical definition of both:
Here is a classic example of a false color image: A forward looking infrared (FLIR) camera (the image to the right). By creating a representation of wavelengths normally invisible to the human eye, we are able to discern the different temperatures present in this scene.
But there are a multitude of reasons for creating false images. Sometimes colors are enhanced, or even added, to represent some characteristic in the image, such as chemical composition, velocity, distance or to simply enhance the differences between materials. Have you ever increased the contrast on your television or an image on your computer so you can better discern some detail? You’ve just created your own false image!!
The same goes for the moon and Mars. With both planets being mostly uniform in their respective colors, creating false images can help us distinguish something as simple as peaks and valleys. Here is an example using the moon:
On the left side is the true color image of the far side of our moon, a mosaic constructed from Lunar Reconnaissance Orbiter images. This is what you would see if you were to directly observe the terrain. Given the uniform color it is very difficult, if not impossible, to accurately judge the peaks and valleys.
On the right side is a false color image of the same side of our moon, a topographic map of the altitude of the Moon’s surface obtained by the Clementine orbiter mission (1994). Measurements made with a laser altimiter. Redder areas are higher, blue/purple areas lower. [source] (more Clementine images here)
In this instance a false color image was generated of the moon to provide a clear, visual representation of the lunar topography.
In the false color Mars image used at the conspiracy website, it’s very possible NASA color corrected the image for no other reason than to better distinguish the size, shape and locations of the rocks.
So to wrap things up, the bottom line is Mars is reddish in color and the moon appears gray. Period. End of story.
I guess my bigger question concerning this conspiracy is, why would the government have any interest in covering up the real color of Mars or the moon (yes, there is a conspiracy out there that the government is covering up the real color of the moon)? I suspect it has something to do with the belief Mars and the moon are actually inhabitable and the Mars/moon color coverup is part of the government’s alien/UFO coverup.
