Scientists did not expect to find much water ice on Mars which is likely the third largest water reservoir on Mars.
Would you like to enjoy the Mars sunset, then continue reading the article. We are pleased to introduce you some images of Mars sunset realized by NASA.
Initially, NASA’s Viking 1 lander showed us the first time Mars sunset in 1976. Several Red Planet robots have since sent back a different kinds of opinions of Martian sunrises and sunsets, including color-corrected, blue-hued images.
Let’s discover when and which rovers take images of Mars sunset and sunrise.
- For first time, as we have mentioned above Viking 1 lander realized the first photo in 1976.
- Viking 2 captured the Mars sunrise on June 14, 1978.
- NASA’s Spirit Mars rover captured Martian Sun on May 9, 2005.
4. Curiosity Mars rover captured another blue view of the Sun which had become a short move in 2015.
Here is the image of 2015.
- And nowadays, Insight lander has captured Mars sunset and sunrise in 2019.
Mars is farther from the Sun than Earth, that is why the Sun appears only about two-thirds the size we see when we watch sunsets here on Earth.
Maybe you think about why Mars planet is red but some images are blue. Here is the answer. As it is famous for us Mars is Red Planet because of iron oxide (like rust) in its soil. The planet’s distinctive reddish hue is visible from Earth even without the aid of a telescope. Just as colors are made more dramatic in sunsets on Earth, Martian sunsets would appear bluish to human observers watching from the red planet.
“The colors come from the fact that the very fine dust is the right size so that blue light penetrates the atmosphere slightly more efficiently,” said Mark Lemmon of Texas A&M University, College Station, a science team member of the Curiosity rover mission. “When the blue light scatters off the dust, it stays closer to the direction of the Sun than light of other colors does. The rest of the sky is yellow to orange, as yellow and red light scatter all over the sky instead of being absorbed or staying close to the Sun.”
