The Sunset on Mars in a 360° Vr Simulation. Take a look at the stunning sunset on Mars in 360 VR video. The sky on Mars is red, while its sunsets are blue. The reason behind this is similar to why our sky is blue and our sunsets are red. The light from the Sun scatters based on what’s in the atmosphere. Sunlight comprises light of many different wavelengths, and molecules and dust particles only interact with specific waves. The scattering of light by these particles is key to the color that we see.
