red mania

Mars-mania!

Valles Marineris is the largest canyon in the Solar System. It’s so wide that from one side, the opposite rim would be below the curve of the horizon. From here, you’ll catch some spectacular blue sunsets in the normally red sky, which gets its color from the dust absorbing most of the blue light and the way sunlight is scattered by the atmosphere.
