First high-def pictures of Mars

天问一号火星影像发布

The China National Space Administration (CNSA) on Thursday published three high-resolution images of Mars captured by the country's Tianwen-1 probe. These images include two panchromatic images and one color image, said CNSA.

国家航天局3月4日发布3幅由天问一号探测器拍摄的高清火星影像图，包括2幅全色图像和1幅彩色图像。

The panchromatic images were taken by the high-resolution camera of Tianwen-1 at a distance of 330 to 350 km above the surface of Mars, with a resolution of about 0.7 meters. In the images, Martian landforms such as small craters, mountain ridges and dunes are clearly visible.

全色图像由高分辨率相机在距离火星表面约330千米-350千米高度拍摄，分辨率约0.7米，成像区域内火星表面小型环形坑、山脊、沙丘等地貌清晰可见。

It is estimated that the diameter of the largest impact crater in the images is around 620 meters.

据测算，图中最大撞击坑的直径约620米。

The color image is of the red planet's North Pole region taken by the medium-resolution camera, CNSA said.

彩色图像由中分辨率相机拍摄，画面为火星北极区域。

Tianwen-1, the country's first independent Mars mission, was launched by a Long March 5 heavy-lift carrier rocket on July 23 from the Wenchang Space Launch Center in Hainan province, kicking off the nation's planetary exploration program.

2020年7月23日，长征五号重型运载火箭在海南省文昌航天发射中心成功发射了我国首个独立火星探测任务“天问一号”，开启了我国行星探测计划的序幕。
