It is known that NASA sent a rover to Mars last year. This Sasa Rover is researching the weather on Mars. Curiosity cameras in Rover have already taken some photos of Mars and sent them to Earth. Recently, another photo was also sent to Earth. There are clouds in the sky above Mars. The Martian climate is dry. Clouds are a rare phenomenon.
