Mars is inspiring human imagination for Millennia, mainly because it has a red color, which earned it from the title “Red Planet”. Its color was associated with blood and war by ancient Romans; Thus, he named it after his deity of war. The result of redness is, scientifically, of iron oxide – rust that coats the surface of Mars. Nevertheless, surface images produced by robotic probes have shown more subtle spectrum. Many areas look like dusty tan or rusty brown. Even the pole refers to the nickname of the planet, introducing water ice and bright white due to frozen carbon dioxide that expand and contract with seasonal sunlight.
Mars is not only red: binoculars reveal color, ice cap and a complex palette of hidden characteristics.
According to a recent article Published By conversation and reinstated on space.com, iron rich minerals Mars planet It is rusted, this is the reason why it is rusty. For example, how iron and oxygen give their color to blood, Martian dust also rust naturally. Polar Cap, which are made of frozen water and carbon dioxide and have clearly different colors, are usually white. The sunlight motivates the layer of dry snow to subdue and fill again, causing them to expand and contract with the cap season.
Images taken by previous missions and Rovers reveal the palette of Mars, butTelescope And Spacecraft Equipped with Ultraviolet And infrared cameras hold false images, causing some confusion about the true color of Mars.
Spectral observation, infrared and ultraviolet images, and the presence of the wide array of electromagnetic spectrum, are assisting scientists in investigating the habit of Mars, history, composition and potential past.
Mars may still look red in the sky, but its real story is rather more complex. Thanks to science and high-resolution cameras, our understanding of this neighboring world is still coming out.
