Sunset on MarsADDPMP662
A day on Mars lasts 24 hours and 39 minutes, so sunrise and sunset follow nearly the same rhythm as they do on Earth. However, sunrises and sunsets on Mars offer a different palette of colors than they would on Earth.
Indeed, in the Earth atmosphere, dust and other fine particles scatter the blues and greens from the setting or rising Sun to color it yellow, orange and red. On the contrary, Martian sunsets typically stand out for their blue color. Fine dust in the atmosphere permits blue light to penetrate the atmosphere more efficiently than colors with longer wavelengths. Moreover, because Mars is farther from the Sun than Earth, the Sun appears only about two-thirds the size we see when we watch sunsets from Earth.
According to Space.com, NASA’s Viking 1 lander was the first to capture the sun setting on the surface of Mars on August 21, 1976. Two years later, Viking 2 captured a sunrise and since then, both sunrises and sunsets have been recorded by Spirit, Opportunity, Curiosity and Perseverance rovers and other missions.
