Watch the strange colored clouds of Mars in this video of NASA’s Curiosity Rover

If you were an astronaut on the surface of Mars and look at the sky just before dusk, you could see clouds that shine in red and green tones. Although the scenario of a person contemplating the extraterrestrial sky still seems distant, the Rovers, As NASA’s curiosity, occasionally they share videos of the strange iridescent clouds of the red planet.

Martian clouds are composed of water ice or carbon dioxide ice. Those formed by dry ice are the most common and are also the only ones that produce the iridescent light phenomenon. The “Nacarado” effect is explained by the dispersion of the sunlight of the west through ice crystals. Only red and green tones manage to cross the dense frozen layer, which gives the clouds that particular color. As it is a phenomenon typical of the sunset, experts know them as night clouds or twilight clouds.

The last video was taken during the Marciano 4,426 day of the Curiosity mission. According to NASA, the Mastcam instrument on board the explorer took photos of the sky for 16 minutes. The phenomenon of iridiscence was first captured in 1997. Since then, the Rovers They arrive in Mars observe the sky to see rainbow before dusk. Curiosity was able to detect the noctilucent clouds until 2019. With this video, it is the fourth time that the explorer presence.

Colored clouds are still a great mystery, although they always appear at the same time of year. Some astronomers await the “cloud season” to alert the Rovers To prepare your recording instruments. “Each sighting is an opportunity to learn more about the size of the particles and the growth rate of the Martian clouds. That, in turn, provides more information about the planet’s atmosphere ”, NASA affirms.

The Curiosity vehicle arrived in Mars in 2012 with the purpose of studying the climate of the planet and its relationship with geology. To achieve their goal, NASA engineers added five different chambers, spectrometers, radiation detectors and environmental sensors. The Martian sky is not his priority, but he has captured some of his best photos, such as the nostalgic image of a blue sunset and the sun’s rays crossing the carbon dioxide clouds.
