How come there is no color pictures from Mars ?

Question

i wana see more color pictures, why didn't they send more color pictures from mars? it doesn't make any sense
is it because of the huge data they have to send and Black and white takes much less data space?

Answer 1

It may depend upon the camera image that you're looking at. I think the rovers' cameras captured light in all forms of the spectrum -- like UV and infrared... those pictures aren't "colored" becuase we don't naturally see those colors... you can colorize them, but that's not a fair representation either.

I think there are quite a few pictures in the visible spectrum in color.

(Note, for example, this image was filtered a 440 nm wavelength... not something in the visible spectrum:

You can learn about the filters at the bottom of this page:

Answer 2

Yes, black and white takes less data. Actually a color picture is nothing more than three black and white pictures taken of the same scene through red green and blue color filters and recombined on Earth into a color picture. It only takes 1/3 as much data to send one black and white picture.

Answer 3

It is because they are trying to hid the fact that the sky on mars is blue and that there is plant and fungus life on it. If you notice the nasa picture of the rover!! The blue on the american flag appears purple, If you add the right amount of blue to the picture to get the flag right the view is asounding. I have a couple of sites that show doctored and un-doctored pics side by side, make up your own mind as to why they only release certain pics, what is there that NASA needs to hide??????

This site below makes it easy to see how they doctored the images, and shows a base for judgement on color, The American Flag!!!

Answer 4

keep in mind also, that a color photo will be monochromatic when the image is all of the same hue, regardless of fading.

I tend to see mars a lot like iraq, things were just all the same color because of the dust covering everything and the intensity of the light reflected.

Here's another source for color photos from Mars:

Yeah, the Rovers send B/W photos because they require less data and transmission time, but there are plenty of color photos, too.

Answer 6

You get extra precise preparation in case you utilize filtered black & white. your place digital camera has a chip in it that has 3 styles of sensors arranged in style of a checkerboard development, that respond to distinctive colorings. in the main elementary association, a million/2 the sensors respond to eco-friendly mild, a million/4 to crimson mild, and a million/4 to blue mild. so which you actual desire 4 sensors to make a "pixel" on your digital camera. And, because those 4 sensors are no longer at precisely the comparable spot, you don't get precise preparation suitable to the colour at one tiny spot. Your digital camera's application in many situations compensates for this by utilising making guesses and averages, and producing a image that is "attractive" extremely than extremely precise. on the Mars probe, they desire some thing precise. The image sensors only degree intensity of sunshine, like a B & W digital camera. They take various B & W photos of each and every scene, each and every time utilising a distinctive coloured clear out, and that provides them an extremely precise theory of ways plenty crimson, how plenty yellow, how plenty eco-friendly, etc. is interior the scene--plenty extra properly than a ordinary multi-shade checkerboard sensor could. on the floor, they combine the countless filtered photos to offer some thing that is comparable to what your eye might see.

Answer 7

Yes, color takes lots more bandwidth. But I've seen color shots from Mars. Have you been to the NASA site?

You got 3D glasses? There are several cool 3D images there, too.
