Chinanews, December 17th, does the heavy launch vehicle work?

How?

Wu Yanhua, deputy director of the National Space Administration and deputy commander-in-chief of the lunar exploration project, said on the 17th that key technology research and iterative optimization of the plan are in progress, and will be submitted to the state for approval when conditions are ripe.

  The Information Office of the State Council held a press conference on the 17th. The person in charge introduced the mission of the lunar exploration project Chang'e-5.

A reporter asked, during the "14th Five-Year Plan" and a period in the future, what major engineering tasks will China Aerospace need to implement, and what other policies will be issued?

  In this regard, Wu Yanhua made a summary of six aspects.

  First, centering on the theme of lunar exploration, the basic plan defines the four phases of the lunar exploration project, including four missions in total.

The first mission was the Chang'e-4 landing patrol survey on the back of the moon; the second mission was the Chang'e-6. "We will further optimize and demonstrate the engineering goals and scientific goals," said Wu Yanhua. "There are also Chang'e 7 and 8 in the plan. We plan to take this mission as an opportunity to cooperate with relevant countries and international organizations to jointly demonstrate the basic capabilities of the initial construction of lunar research stations, or to verify core technologies."

  Second, the plan for planetary exploration is basically clear and awaiting national approval.

According to Wu Yanhua, the first mission has been implemented, the first Mars exploration mission, Tianwen-1, which was successfully launched in Wenchang on July 23 this year. The current state is very good. It has flown about 370 million kilometers and is currently more than 100 million kilometers away from the earth. .

If according to the predetermined plan, it will reach Mars in mid-February next year and begin to orbit the fire detection.

In mid-May next year, it is planned to land on Mars for inspection and exploration.

"In addition, we have also planned three planetary exploration missions, including an asteroid detection and sampling, a Mars sampling return, and a Jupiter orbit exploration and planetary traversal exploration," said Wu Yanhua.

  Third, China's manned spaceflight.

Wu Yanhua pointed out that according to the "three-step" plan, next year and the next year will be very busy times for the construction of the third phase. "We plan to use two years to complete a total of 11 space station launch missions, including the core of the planned launch in the first half of next year. There are also two test cabins, four cargo spacecraft, about four manned spacecraft, and a total of nearly 11 missions to be completed in two years; then, a large number of scientific experiments on orbit will be carried out," said Wu Yanhua.

  Fourth, the ability to enter space.

Wu Yanhua said that after the success of the existing rockets, especially the "Fat Five", the following plans will be made.

  The first is to make full use of the Long March 5, 6 and 7 new-generation carrier rocket technology to improve the non-toxic and pollution-free new rocket sequence and reintegrate to ensure that the new generation of carrier rockets can be serialized to meet various orbits and various weights The launch mission of the aircraft, such as the Long March 8 announced on the 16th, is planned to be carried out at the Wenchang launch site for the first time around mid to late December.

  The second is the heavy launch vehicle?

How?

"This is definitely going to be developed. We are conducting iterative optimization and demonstration of key technology research and solutions. When the conditions are ripe, we will report to the state for approval," said Wu Yanhua.

  Fifth, various application satellites.

First of all, Beidou navigation satellites have provided global services and must operate stably.

Secondly, remote sensing satellites, whether for national missions or commercial space missions, have been booming in recent years, with various uses.

There are also communication satellites, including geostationary orbit and low-orbit communication satellites.

The above three types of satellites are collectively referred to as the national civil space infrastructure, and they must provide powerful support and guarantee capabilities for various fields of the national economy.

At the same time, as an important part of the country's strategic emerging industries, the national civil space infrastructure will also provide better products and services for the production and life of the masses.

  Finally, space science satellites.

In addition to platforms such as moon and planet exploration and manned spaceflight, which can rely on space scientific exploration, it is also necessary to develop and launch special space scientific satellites to carry out space scientific exploration and research.
