Today (June 11th), the National Space Administration held the unveiling ceremony of the first batch of scientific images of Tianwen-1’s landing on Mars, and released the panoramic view of the landing site, the landform of Mars, the China imprint and the patrol photo taken by the rover Zhu Rong. The release of the first batch of scientific images marks the complete success of China’s first Mars exploration mission.

The panoramic view of the landing site is a 360-degree circular shot by the navigation terrain camera on the mast of the rover before it leaves the landing platform, which is made by correction and mosaic. The image shows that the terrain near the landing site is flat, the horizon of Mars can be seen in the distance, and the abundance and size of stones are consistent with expectations, indicating that the independent selection of landing sites and hovering obstacle avoidance are effective.

The topographic map of Mars is the first topographic image taken by the navigation topographic camera after the rover reaches the surface of Mars. The image shows that the near surface is flat, with stones of different sizes, smooth edges, light colors and a semi-buried shape, and there is an annular pit in the distance. There are dark and angular stones on the edge of the annular pit, and there are several sand dunes in the distance.

The "China Impression" map is an image of the landing platform taken by the rover when it travels about 6 meters east-south of the landing platform. The image shows that the landing platform is shining, the national flag is bright red and square, and the surface topography is rich in details.

The "photo tour" picture shows that the rover travels to the south of the landing platform about 10 meters, releases the separation camera installed at the bottom of the car, and then the rover retreats to the vicinity of the landing platform. The separation camera photographed the moving process of the rover and the photo of the rover and the landing platform. The image is transmitted to the rover by wireless signal, and then relayed back to the ground by the rover through the circulator.
China’s first Mars exploration mission was fully demonstrated in 2013, and the project was approved in January 2016. On July 23, 2020, the Tianwen-1 probe was successfully launched in Wenchang, Hainan. After the stages of fire transfer, Mars capture, Mars berthing, off-orbit landing and scientific exploration, the engineering task was carried out smoothly as planned. As of June 11, the orbiter was running well in the relay orbit, and the "Zhu Rong" rover had been working on the surface of Mars for 28 Mars days.
