“These are the first close up pictures of Mars' surface taken by China，” said Bao Weimin, a scientist of the Chinese Academy of Sciences.
The pictures were taken at different distances from Mars.The two black and white pictures were taken by the high resolution camera on Tianwen 1 when the probe was about 330－350 kilometers above the Martian surface.As for the color picture, it was taken by Tianwen 1's medium resolution(中分辨率的)camera when the probe was about 5,000 kilometers above the red planet.It shows Mars' North Pole.
The high resolution camera can take both color and panchromatic (全色的) pictures. Panchromatic pictures, which are black and white, are the clearest, having the largest amount of data for scientific study, said Liu Tongjie.The medium resolution camera, can only produce lesser clear pictures.Scientists put the panchromatic and color pictures together to form a clear and beautiful color picture, Liu added.
