Mars

"the Red planet"

Iron oxide in the Martian soil is responsible for the deep rust color that long ago earned Mars the sobriquet the "Red Planet.” The U.S.-built Viking spacecraft confirmed this attribute of Mars when they landed on its surface in the mid-1970's and transmitted back photos of reddish-brown rocks stretching to the horizon of a reddish sky. Many features on Mars bear a similarity to those found on our planet, but often taken to an extreme.
