Mars Cam Views from NASA Rover during Red Planet Exploration #Mars2020

Take a look thru Perseverance’s eyes.

Why does the Martian sky look grayish blueish?

The sky is not blue as on Earth because Martian air is extremely thin, and the dust particles in the air are large relative to the wavelength of visible light. The dust particles preferentially absorb blue light and effectively act as mirrors by scattering the remaining wavelengths: this produces the butterscotch color of the atmosphere…

If the Martian atmosphere were free of dust, the daytime sky would appear blue, because of Rayleigh scattering by the molecules (primarily carbon dioxide) that make up the atmosphere. Because the atmosphere is thinner than earth’s atmosphere, the Martian sky would be a darker blue than ours, much as the sky on earth appears at high altitudes with a similar density of air molecules. webexhibits

As amazing as the rovers are, until we can see with our own eyes (and even then, the helmet will probably have some effect on color) only science fiction can put a human on Mars. Try my series about a near-future colony.

In this marvelously detailed journey into the near-future, colonists cling to humanity’s first fragile foothold on the Red Planet, and struggle on through generations, battling the deadly planet and each other. Because no matter how noble the aspirations, how alluring the technologies, survival requires individual intelligence, ingenuity, and courage.
