Why is the Russian satellites are different from American ones?

This is a photo - one of the most beautiful and amazing images of the Earth. On the Russian photo clearly visible differences in color regions of the Earth and detailed outlines of the mountains, which makes them incredibly beautiful.

They are not only unique in its kind, but also different from the many photos taken by NASA.

Photo below: This is a photo of the region of the Red Sea, made by Russian satellite Electro-L. Clearly visible differences in color earth depending on site and can be clearly seen by their high mountains circuits.

What caused such a dramatic difference? The whole point in using a variety of methods of interpretation of satellite images.

Weather satellite Elektro-L, send photos to the command center on the ground every half hour, but in principle can send them every ten minutes.

It was launched in January carrier rocket Zenit and is now at an altitude of 36,000 kilometers above the equator.

Some shots from the Russian satellite, may seem more accurate than the image of NASA. But the U.S. space agency in a hurry to refute this view.

Photo: The striking image of the Earth, made by Electro-L on February 26. This picture is significantly different from those made by NASA, because of differences in the interpretation of information.

Dr. Robert Simmon of the Goddard Space Flight Center in Maryland, said that Russia’s picture is no better and no worse than those that have been made by NASA.

He said: "These photos taken by Elektro-L, combined visible and near-infrared region of the spectrum, so they are represented by the Earth as it can not be seen by human eyes - the vegetation is red in color, for example."

"They are no better and no worse than that of NASA, but they show different things."

Electro-L takes pictures in three different frequency bands of the reflected light, one red, and two near infrared region of the spectrum, one of which is ’indicator plants’ as plants clearly reflect light in the near infrared spectrum.

This system allows you to simulate the usual eye color photos of the red, green and blue.

Photo: Another image made by Electro-L is significantly different from the methods used by NASA to capture and decode their satellite images. NASA photo below gives less attention to color of vegetation and more realistic

NASA weather satellite GOES, does not remove the near-infrared region and makes black-and-white photographs in the infrared frequency range.

Take a picture of then painted: add red, green and blue colors, with the help of 3-D technology.

In the photo NASA image was shot as he would have seen the human eye, while photo Elektro-L opens a wide scope for interpretation of the human image, though smaller than in reality.
