NASA SHOWS US A BLUE SUNSET ON MARS

NASA SHOWS US A BLUE SUNSET ON MARS 2

Have you ever wondered what a sunset would look like on Mars? Wonder no more, because this video from NASA shows just what you’d see at the end of a Martian day

This video is made of images taken by NASA’s Opportunity rover between November 4th and 5th, 2010. A few of the frames are enhanced or simulated to give the movie a better flow, but this is as close to a real Martian sunset as human eyes will see for at least a generation.

And it looks nothing like a sunset does on Earth. On Earth, incoming sunlight is scattered in all directions by the gases and particles in our atmosphere. The blue light is scattered more than other colors because it travels on a shorter wavelength, so we see a blue sky. When the Sun is low on the horizon around sunrise or sunset, the sunlight is passing through more atmosphere to your eyes. This means more of the blue light is scattered, allowing some of the longer wavelength blue and yellow hues to escape and reach your eyes, accounting for the amazing array of warm colors.

Mars-Sunset

The same thing happens on Mars, but because the atmospheric composition is different, light scatters differently to give the Martian sky its characteristic red hue. The dusty particles and gases in Mars’ carbon dioxide-rich atmosphere scatter the sunlight reaching the planet such that the blue light is almost completely eliminated and the longer, reddish wavelengths survive to be seen.

Just like a sunset on Earth, the sunsets on Mars pass sunlight through more atmosphere, scattering light such that some blue light survives, making for a blue sunset. And because the Martian atmosphere is so much thinner than the Earth’s — Mars’ atmosphere is only about one percent as thick at the Earth’s — we don’t see the scattering sunset light diffusing through the sky as much. The blue light stays much closer to the Sun.

Opportunity landed on Mars in 2004 and was designed to last just 90 Sols (90 Martian days). Lucky for us Earthbound humans it’s still working more than a decade later, capturing vistas we would never otherwise see.

Plain bullshit. Nasa is as fake as can be.

Guest

Awesome martian sunset.

Blue sky on mars means there is moisture right?

Guest

Yep. That’s why we have a blue sky. It’s how water reflects the spectre of light.

Guest

Aliens

Guest

I figured it would be a deep red. Being the red planet and all.

Guest

You should change the name of this page to: “Shit we assume because we don’t have a proper understanding of science”. Blue sky on Mars!! You guys kill me with this shit. Lmao!!

Guest

Lovely

Guest
Guest

This is spectacular and gives me much imagination as a sci Fi writer

Guest

Nothing wrong with that.

Guest

last thing the world needs is another sci fi book aye mate?

Guest

Blue beam

Guest

I would say it has something to do with the gases that make up mars atmosphere. But it looks like a moon.

Guest

In 97, they showed us a salmon pink sunset. I say we all go see for ourselves. Who’s with me? http://apod.nasa.gov/apod/ap970804.html
