Everyone of us are familiar that sky seen from earth appears blue during day time. However, many of us do not know that Sky on Mars appears red. There is a scientific reason for this.

Martian surface is covered with the red iron rich dusts. During storms dusts are thrown up into the sky. These storms occurs from time to time on Mars. These red dusts particles is the main reason that Martian sky appears red in color. However, sky from Mars does not appear only red but also blue. This is because Mars sky changes according to the weather conditions. When there is no recent storms the sky appears blue as earths sky. Due to the Mars thin atmosphere day will be darker than earths sky.

Thus red dust is the reason for sky appearing Mars sky red.
