At the press conference of the 2017 China Aerospace Day held yesterday, Tian Yulong, chief engineer of the National Defense Science and Technology Bureau and secretary general of the National Space Administration, said that the launch of the lunar exploration project No. 5 will be carried out at the end of this year to complete China’s first trip from the moon. The major mission of sampling back, when the mission will be undertaken by the Long March 5 rocket.
Tian Yulong said that in 2017, China Aerospace will meet new missions and new challenges. In addition to the mission No. 5, the Long March V carrier rocket will also undertake the task of sending the experimental satellite No. 18 to space. In addition, there will be multiple missions such as space science satellites, new remote sensing and communications satellites.
He also mentioned that at present, the Long March 7 carrier rocket and the Tianzhou-1 cargo spacecraft are poised for launch in Hainan, and will soon rush to space and dock with Tiangong-2.

On the 5th of November, the expedition will bring back the lunar soil.
The No. 5 detector, which undertakes the last step of the three steps of “around, fall and return†of China’s lunar exploration project, has recently completed the prototype hot test of the lander propulsion subsystem, which marks the key to the development of the No. 5 project. Success in one step. It was learned from the China Aerospace Science and Technology Corporation, which is responsible for the overall development work of the No. 5, that the development work is currently carrying out the final sprint of the detector in the correct stage, carrying out all relevant work in the final assembly test phase, and the technical status and quality control of the No. 5 The plan is going well.
嫦娥5 will create four “first time†for China Aerospace
According to the plan, the 8.2-tonne 嫦娥5 will be launched from the Wenchang Space Launch Site of China at the end of November 2017.
This mission is expected to achieve the four “firsts†since the launch of our space activities: the first automatic sampling on the lunar surface; the first takeoff from the lunar surface; the first unmanned rendezvous on the lunar orbit of 380,000 km away; The soil returned to Earth at a speed close to the second universe.
Academician Ye Peijian, chief consultant and chief designer of the lunar exploration satellite of the Chinese Academy of Aerospace Science and Technology Corporation, said that the 嫦娥5 includes four parts: the orbiter, the returner, the riser and the lander. After reaching the lunar orbit, the orbiter and returner flew around the moon, and the lander and riser landed on the lunar surface. The lander is sampled on the lunar surface using the sampling device mounted, and then loaded into the container carried by the riser.
Is there a “big move†in China’s lunar exploration?
Wu Yanhua, deputy director of the National Space Administration, said earlier that in 2018, China will launch the No. 4, implementing the world’s first soft landing on the back of the moon and patrolling. At the same time, a relay satellite should be launched at L2 point in Lagrange, Japan, as a relay communication data transmission, providing services and support for moon and even deep space exploration.
Wu Yanhua said that according to the National Space Agency's plan for future lunar exploration, the fourth phase of the lunar exploration project was launched, including the launch of Lunar 6 and other lunar probes around 2020 to realize the return of the lunar pole region.
Will China engage in manned landing on the moon?
China’s fourth aerospace white paper “2016 China’s Space†pointed out that in the next five years, China will lay the foundation for manned exploration and development of the Earth and Moon space. Wu Yanhua has responded to this. At present, China needs to conduct in-depth research and demonstration and multi-program comparison on the scientific goals and technical approaches of manned landing on the moon.
Launched 28 times a year! China's Long March rocket force to pick the United States and RussiaIn 2016, China's rocket launch reached 19 times, only one less than the United States, and for the first time exceeded Russia (18 times), making the world pay attention to it.
According to the latest news from the China Aerospace Science and Technology Corporation's 2017 model work conference, the long-range rocket family's full-year aerospace launch plan for 2017 will reach a record 28 times, with an average of 13 days to launch!
More critically, 16 of these were major special missions or first flight missions.
1. This year, China's first detector No. 5, which implements the monthly sampling and return mission, is technically difficult and complex, and is of great significance to the lunar exploration project and deep space exploration.
2. For the manned spaceflight project, the Tianzhou-1 cargo spacecraft will be rendezvous and docked with the Tiangong No. 2 Space Laboratory to verify and break through the propellant on-orbit replenishment technology, laying a technical foundation for the construction of the space station.
3. The Beidou satellite navigation system will enter the critical period of global network construction.
4. The high-scoring special project will launch the high-scoring satellite No. 5, which will be the first high-spectrum Earth observation satellite with international advanced level.
On April 20-24, the Long March 7th Second Launch Vehicle will send China's first cargo ship, Tianzhou No. 1, into space, fully unveil the curtain of China's space station construction, and challenge the zero-window launch for the first time.
