On the photo made by the PerserVance Marshow, is actually not a rainbow, but another phenomenon is reported on the NASA page on Twitter.
in the agency clarified that the rainbow could not appear, because there is not enough water on the planet for condensation, and it cannot be liquid due to too low temperatures. Therefore, drops are not formed, and the light is not reflected from them.
“Many ask: is it a rainbow on Mars? No, it can not be here. This arc is a flash from the lens,” explained in NASA.
Perseverance Planet Shift sat on the surface of Mars in the area of Crater Ezero February 18. This is the fifth American squirrel who visited the planet. Its task is to collect samples of soil, which will be delivered to the ground around ten years. The device also has an oxygen production system from the atmosphere of Mars and the Ingenuity helicopter, which must fly in the near future.
