Why Is The Sky Blue?
9. Mars Red Sky
Travelling to Mars is something that has fascinated us for generations, and the reality of doing so appears to be getting closer. We have not sent people there yet, but we have sent probes and explorers that have sent us back information about the planet, including pictures from its surface. A common question is why Mars sky appears to be red.

The simple answer to this is that Mars is a dusty, dry planet and storms will occasionally send countless red dust particles into the sky, hence its appearance. When the particles have settled, Mars sky will be as blue as ours is, only it will be a deeper blue.
