The Odyssey spacecraft sees blue dunes on Mars

The Odyssey spacecraft sees blue dunes on Mars

Mars is called the Red Planet. When you look at the night sky, you need to know why. However, the photo from the US investigation presents it differently.

In the sky, we recognize Mars by its red color. It is caused by the presence of iron on its surface. And because the planet’s atmosphere is sparse, you can see the color from Earth, especially in a telescope.

In April, NASA released a unique, previously unpublished image that may lead us to question whether Mars is also blue.

You see white in the picture Bluish dunes occur in the polar cap region of Mars. It covers an area roughly the size of France.

The image is actually a puzzle of images taken by NASA’s Mars Odyssey spacecraft, which has been orbiting the planet since October 2001. Its main mission is to use a spectrometer to study the composition of Mars’ surface and map water on it.

The image shown is from the thermal imaging system spectrometer. This probe device naturally sees Mars in colors other than the human eye, which are the wrong colors. One can see the cold Duma as dark places.

Areas with lower temperatures are detected by a spectrophotometer in blue tones, while warmer areas with sunlight are shown in yellow and orange to dark red.

Spektrometr NASA experts help identify planet matter with It measures how Mars warms and cools.

The title image is just a section of the image that covers an area of ​​thirty kilometers wide. Here you can see it in full view.

The image is part of a batch of photos to celebrate the 20th anniversary of Odyssey, the longest-serving spacecraft orbiting Mars.

“The Odyssey spacecraft provided us with invaluable information. Before Odyssey, we didn’t know exactly where the water was on Mars,” NASA quoted project scientist Geoffrey Plott of the NASA Jet Propulsion Laboratory that controls the spacecraft as saying.
