At the entrance of the exhibition area, the 1:1 model of the "Dongfanghong-1" satellite is extremely spectacular.
On the left side of the exhibition area, the models of the Long March series carrier rocket family and the Kuaizhou series carrier rocket are lined up like troops. The Long March 5 carrier rocket, nicknamed "Fat Five", is also among them.
As my country’s first self-developed new-generation large-scale carrier rocket, the Long March 5 rocket has set a number of "mosts"-the largest take-off mass, the largest take-off thrust, the largest body structure, the strongest carrying capacity, and the highest carrying efficiency. An important support for my country's lunar exploration project, space station construction, and the first Mars exploration mission.
The return capsule, parachute and extravehicular aviation suits of Shenzhou 10 attracted many spectators to stop.
Many people still clearly remember the exciting moment of the hand-controlled rendezvous and docking of Shenzhou-10 and Tiangong-1 in 2013.
"What everyone sees now is the simulation model of the'Tianwen No. 1'Mars probe. On July 23 this year, at the Wenchang launch site in Hainan, the Long March 5 Yao-4 launch vehicle carried my country's first Mars exploration mission'Tianwen'. The No. 1 probe ignited and lifted off.” Volunteers at the scene introduced to the audience.
Zhang Rongqiao, chief designer of China's first Mars exploration mission project, introduced at the China Aerospace Conference that as of 8:30 on September 18, the "Tianwen-1" probe has flown 155 million kilometers and is 18 million kilometers away from the earth.
During the flight, "Tianwen No. 1" has successfully completed the acquisition of earth-moon photos, the first midway correction of the orbit, and the self-check of the payload.
"Tianwen-1" will fly in the Earth-fire transfer orbit for about 7 months. It is expected to be captured by Mars gravity in February 2021 and enter the ring-fire orbit. The Landing Patrol is expected to land on Mars in May 2021.
If the first Mars exploration mission is successfully completed, China will become the first country in the world to achieve the three goals of “surround, land, and patrol” Mars through a single mission.
The starry sky is vast, and the exploration is endless.
As the world's aerospace has entered a major development, China Aerospace has embarked on a new journey towards higher and farther goals.
At the China Aerospace Conference, Yu Dengyun, deputy chief designer of China's lunar exploration project, said that my country's lunar exploration project is progressing steadily. It is expected that the "Chang'e 5" will be launched before the end of this year to achieve a soft landing and sample return on the moon.
Zhou Yanfei, deputy chief designer of China’s manned space engineering, said that my country’s current Long March series of carrier rockets cannot meet the needs of manned moon landings. At present, we are continuing to deepen the demonstration of manned moon landing plans and consider using mature technology to develop a new generation of manned manned. Launch vehicle.
The new generation of manned launch vehicle can send manned spacecraft and lunar lander into the Earth-Moon transfer orbit.
2 Meteorological satellites, navigation systems, emergency rescue, biotechnology, disaster prevention and mitigation, smart agriculture
Aerospace applications serve public life
Unpredictable and far away...In the impression of many people, the aerospace field is covered with a veil of mystery, as if it is very far away from us.
As everyone knows, the application of aerospace technology and its products has already penetrated into all aspects of people's production and life: from meteorological satellites and navigation systems, to land and resources monitoring, ecological environmental protection, to emergency rescue, biotechnology, and aerospace technology to create a better life and help Improving social governance capabilities has gone from dream to reality.
