How are sunsets on Mars?

For several years we have known the shape of the sunset observed from the red planet. And they want to be different from the show offered to earthlings.

It planet mars, as finally everyone who has not (yet) been trampled by humans, crystallized a series of questions. Not necessarily most broadcasts, the question the sun has set on Mars, however, it provides an answer that’s a shame to ignore. It is shared on the website NASA more than seven years ago now.

Sunset on Mars: not red, not orange

Thanks to NASA’s Curiosity rover, this image of the sunset on Mars was captured on April 15, 2015. And they don’t paint the show mostly red or orange. These colors appear completely absent in the visual reports generated, and precisely the rover recorded the colors of its first sunset there.

The bluish color explains

The sunset, captured between two dust storms at Gale Crater, is actually blue. In a another article from the site, Mark Lemmon, of the Curiosity team, describes the phenomenon: “The colors come from the fact that very fine dust is just the right size for blue light to enter the atmosphere more efficiently.”.

Because it’s closer to the sun

“When blue light scatters on dust”continues Mark Lemmon, “It stays closer to the sun than light of any other color. The rest of the sky is yellow to orange, because yellow and red light spreads across the sky instead of being absorbed by or staying close to the sun.
