The China National Space Administration (CNSA) released on March 4 three high-resolution images of Mars taken by China's Mars rover Tianwen-1, including two black-and-white images and one color image.
The black-and-white images were taken by a high-resolution camera at an altitude of 330 km to 350 km above the Martian surface, with a resolution of about 0.7 meters.
Small craters, ridges, dunes, and other features on the surface of Mars are clearly visible in the cameras’ imaging area, with the diameter of the largest impact crater measured to be about 620 meters.
The color image was taken by the medium-resolution camera and shows the north polar region of Mars.
Tianwen-1 is the first Mars rover launched by China, which has been in a parking orbit for scientific exploration since Feb. 26. It is equipped with a high-resolution camera, medium-resolution camera, mineral spectrometer, and other payloads to obtain scientific data.
The high-resolution camera is equipped with two kinds of imaging detectors, which can realize line array pushing and sweeping, and surface array imaging to carry out fine observation of topography and landscape in key areas.
The medium-resolution camera is equipped with automatic exposure and remotely adjustable exposure function, which can draw remote sensing image maps of the whole of Mars and carry out the detection of Mars topography and its changes.
