“Curiosity” left on a mission to Mars more than three years ago. For more than three years, scientists have spotted different events worth revealing. On April 15, a series of photos showing a beautiful blue sunset were sent back home from Mars.
On the red planet, shiny yellow and orange sunset shades turn into blue. From Mars the sun sets in colors of blue, through to the perfectly sized dust particles carrying the light with their shade. It is exactly the same sunset, but in different colors and intensities.
Light from a setting travels in the atmosphere on a much longer path than it does at mid-day, NASA explains.
The planet placed on the opposite side of the sun offers us the privilege of a different perspective. Difference in colors comes from the fact that a very fine particle, like dust, happens to be in perfect symmetry with the light that spots its particular shade of blue.
“When blue light scatters off the dust, it stays closer to the direction of the sun than light of other colors does” Mark Lemmon, researcher at Texas A&M University declares.
News from mars have increased in volume and importance lately, with NASA’ s initiative towards human landing.
We are heading to the development of human life and sustained human presence on Mars and NASA has launched a challenge in that direction.
The competition requests for answers that could envision the development of a sustained environment to support human life on Mars for more than 500 days. Although NASA denies this initiative could be the first step towards colonization, recent life-friendly images show us that premises for planet migration could arise sooner than expected.
After previous studies revealed there’s water on the surface of Mars, now we have a blue sunset. Nitrogen was also discovered some time ago. What else is there? NASA asks. But for in-depth answers, in-depth research is needed and for that to happen, we need to learn how we can experience life in red and blue.
Everything “Curiosity” has reported by now is rather curious, as their one and only goal was to see if there was the slightest chance for the planet to support life, even in the shape of microbes. Their findings exceeded the limits of microbial life, opening visionary paths for macro-universes. Of course what they found by now is hardly enough to make us go there and stay. We couldn’t. But we can think of ways to build up our roads towards the destination that could redefine life from another kind of ground zero.
