<hr />
<p>Original title: China National Space Administration released high-definition images of Mars taken by the Tianwen-1 probe</p>
<p> Today (4th), the National Space Administration released three images from China’s first Mars exploration mission Tianwen-1 The high-definition image of Mars taken by the rover, including 2 black and white images and 1 color image. </p>
<p> The black and white image was taken by a high-resolution camera at an altitude of 330 kilometers to 350 kilometers from the surface of Mars, with a resolution of about 0.7 meters. In the imaging area, small ring craters, ridges, sand dunes and other landforms on the surface of Mars are clearly visible According to calculations, the diameter of the largest impact crater in the picture is about 620 meters. The color image was taken by a medium-resolution camera, and the picture shows the north pole of Mars. </p>
<p> Starting on February 26, Tianwen-1 has carried out scientific exploration in the parked orbit, and scientific payloads such as the orbiter high-resolution camera, medium-resolution camera, and mineral spectrometer have been turned on to obtain scientific data. The high-resolution camera on the orbiter is equipped with two imaging detectors, which can realize linear array push-broom and area array imaging, and carry out fine observation of topography and landforms in key areas. The medium-resolution camera has the functions of automatic exposure and remote control of exposure adjustment, and can draw global remote sensing image maps of Mars to detect the topography and changes of Mars. <
