At 7:18 on May 15th, the landing rover of the Tianwen -1 probe successfully landed in the pre-selected landing area in the southern part of the Martian Utopia Plain; on May 17, the orbiter implemented the fourth near-fire brake and entered the relay Communication orbit; On May 19, the National Space Administration released the images taken by the Mars rover after the separation and landing of the Tianwen -1 probe during the landing process of my country's first Mars exploration mission; at 10:40 on May 22, reach the surface of Mars and begin a tour of exploration.

Chinese building materials people rely on excellent technology and silently adhere
Continue to help the construction of space power
The contribution of building materials people is also behind the Tianwen No.1 mission.

According to the overall task requirements, the scientific research team of China Building Materials General Institute of China Building Materials Group provides 4 series of products for the inspector. Provide 2 series of products for the surround device. The above products are all made of a variety of advanced composite materials. Through mechanical theoretical analysis, intelligent structure design and repeated iterative extreme environment test verification, a number of key technical problems in the application of advanced composite materials for patrol and surround devices in extreme harsh environments such as low temperature, irradiation and electromagnetism have been solved, providing stable technical support for the Tianwen -1 Mars exploration mission.

The image was taken by the rover's front obstacle avoidance camera, facing the rover's forward direction. In the figure, it can be seen that the ramp mechanism is normally deployed, and the two extension rods on the upper part of the image are subsurface radars that have been deployed in place, of which the rover subsurface detection radar radome tube is developed by the Harbin Institute.

Tianwen -1 is equipped with an advanced machine vision system, which injects the acquired Martian surface terrain data into the computer system to form machine vision perception capability, so as to ensure that the lander will identify the landing site independently. In this process, the high-purity Shi Ying glass of Shi Ying Institute of China Building Materials General Institute affiliated to China Building Materials Group is the core component of the navigation inertial measurement unit, which helps to accurately locate and plays an important role. High-purity quartz glass has specific optical properties, cosmic ray radiation resistance, thermal shock resistance, etc., and can be used as a key component of the spacecraft positioning system to ensure the accuracy of positioning to ensure the precise entry of the spacecraft into orbit.
