Focus on the Two Sessions | Dreaming Starry Sky my country plans to implement Mars sampling return before 2030

CCTV News:

During the two sessions this year, representatives and committee members from various fields brought a lot of new news.

Last year, my country successfully completed the Tianwen-1 mission, and the Zhurong Mars rover landed smoothly on the surface of Mars and began to patrol and explore. It also started the pace of my country's exploration of deep space.

Wu Weiren, a member of the National Committee of the Chinese People's Political Consultative Conference and chief designer of China's lunar exploration project, said in an exclusive interview with a reporter from the main station that my country will plan a number of Tianwen series of planetary exploration missions to explore the vast space.

　　Wu Weiren, chief designer of China's lunar exploration project, member of the National Committee of the Chinese People's Political Consultative Conference: We will also have Tianwen-2, Tianwen-3, Tianwen-4 and so on. One of the main follow-up tasks is to detect asteroids in far-reaching space. , to be able to collect samples from asteroids.

After the asteroid is sampled, it is necessary to prepare for the return of Mars sampling, which is hoped to be implemented before 2030.

　　Compared with the lunar sampling return, it is more difficult to launch a sampling return mission to Mars hundreds of millions of kilometers away.

This requires a launch vehicle with greater thrust, and the improvement of the carrying capacity is like adding wings to the planning of deep space exploration, which can fly higher and farther.

　　Wu Weiren, chief designer of China's lunar exploration project, member of the National Committee of the Chinese People's Political Consultative Conference: First of all, we need to solve the high-thrust launch vehicle (problem) to achieve Mars sampling, and then prepare for the crossing exploration of Jupiter or other planets in the solar system.

We hope to complete 100 astronomical units in 2049 and reach a place (detection) of 15 billion kilometers (from the earth), hoping to achieve detection to the edge of the solar system.
