What would the skies look like on Mars? It is known that, due to the characteristics of the planet's atmosphere, the sun's rays, when scattered through the atmosphere, would generate red days and blue sunsets, contrary to what we see every day on our planet.

On Earth, the skies appear blue because our atmosphere is dense, allowing shorter wavelengths of light, such as blue light, to scatter more easily. This is why we see the horizon as blue or sky blue when the sun is overhead. This phenomenon is known as Rayleigh scattering. As the sun moves away from the poles, light rays have a greater distance to travel before reaching our eyes. Because blue rays are scattered at the beginning of their path, what reaches our eyes are the longer wavelengths, such as red light.

On Mars, several factors alter this, causing days to appear different. Gravity is lower, the soil is drier and dustier, and the atmosphere is often filled with numerous fine dust particles, causing long wavelengths of light, particularly red light, to scatter more evenly. Thus, during the day, the sky appears orange because sunlight highlights the oxidized nature of the dust in its atmosphere.

The works in this series prompt us to consider how science fiction and certain scientific circles have their sights set on other planets, especially Mars, speculating about the discovery of new worlds to inhabit. I believe that art can also help us imagine what other horizons would look like if we lived on other celestial bodies.
