The scientific mission of Shenzhou VI manned spacecraft is to realize the launch and safe operation of China's two-person spacecraft, and to carry out scientific experiments such as bone cells on the earth's surface, cardiology, digital photos and experimental spacecraft.
The Shenzhou VI manned spacecraft added more than 40 pieces of equipment and 6 pieces of software, including earth observation instruments, bringing the number of equipment to more than 600 pieces, 82 pieces of software and 65,438+10,000 pieces of components.
Twenty-four cell culture boxes containing beating cardiac myocytes and osteoblasts attached to the wall were placed on the spacecraft, and astronauts and ground staff simultaneously conducted a series of scientific comparative experiments on two identical living cells.
To study the cellular and molecular mechanism of the influence of space environment on the heart and bones, and verify the protective effects of drugs placed in cell culture medium and drugs screened on the ground through space real-time flight. Astronauts operated 24 sample boxes in three periods.
During the operation, astronauts will put the cell culture belt on their legs, and at different times, they will burst two kinds of capsules containing activator and fixative to activate or fix living cells, and investigate the state and changes of cell samples under different gravity conditions before and after the spacecraft enters orbit.
2. Shenzhou VII
Shenzhou VII carrier rocket was launched in 2 1: 10: 4.988 milliseconds on September 25th, 2008. Ignition 120 seconds, the rocket throws away the booster and escape tower; The first and second stages of the rocket are separated in 159 seconds; At the 200th second, the fairing is separated.
The third stage rocket was shut down in the 500th second; In the 583rd second, the spacecraft was separated from the rocket; Then the spacecraft entered the scheduled orbit normally, and the Shenzhou VII spacecraft was successfully launched. At 04:03 on September 27th, the orbit change control program was started, and the orbit change was completed at 04:04.
The spacecraft entered orbit, circled the earth for more than 5 times, and the astronauts left the cabin. 16:35 Zhai Zhigang With the mutual help of Liu Boming and Jing Haipeng, astronaut Zhai Zhigang opened the cabin door and started extravehicular activities. Zhai Zhigang was the first to stick his head out.
He waved to the default closed-circuit camera outside the cabin and then walked out of the cabin. Liu Boming also poked his head out of the engine room and gave Zhai Zhigang a small five-star red flag. Zhai Zhigang took the five-star red flag and waved it at the camera for a while.
Zhai Zhigang then retrieved the solid lubrication experimental samples loaded outside the cabin. 16:58 astronauts successfully completed the extravehicular activity and returned to the orbital module. The door of the orbital module is closed.
3. Shenzhou XI spacecraft
Shenzhou XI spacecraft was launched by the Long March II FY/KOOC-0//KOOC-0/carrier rocket at 7: 30 on/KOOC-0/6,/KOOC-0/7 and 20/KOOC-0/in Jiuquan Satellite Launch Center in 2065.
The purpose is to better master the technology of space rendezvous and docking, and to carry out applications and experiments in the fields of earth observation and space earth system science, new space application technology, space technology, aerospace medicine and so on.
The flight crew consists of two male astronauts, Jing Haipeng and Chen Dong, with Jing Haipeng as the commander. Shenzhou XI spacecraft was developed by China Academy of Space Technology. After two days of independent flight, the spacecraft automatically docked with Tiangong-2 Space Laboratory to form a combination.
Shenzhou XI is the transition from the second step to the third step of China's manned spaceflight project, preparing for the construction of a manned space station in China.
Shenzhou XI is the sixth manned mission in China and the longest manned mission in China, with a total flight time of 33 days.
4. The first quantum satellite "Mozi"
Mozi quantum science experimental satellite was successfully launched by Long March II carrier rocket in Jiuquan on August 6, 20 16 1: 40. The successful launch of this mission marks another important step in China's space science research.
Academician Pan Jianwei, chief scientist of China Quantum Satellite, said that ground quantum communication has built a "network" connecting every city and every information transmission point.
Then the quantum science experimental satellite is like a "javelin", shooting this net into space. When this global quantum communication "heaven and earth network" is woven, massive information comes and goes in it, which is "unconditionally" safe.
On 20th1765438+1October18th, Mozi, the world's first experimental satellite for quantum science, successfully completed its four-month on-orbit test mission and was officially delivered to users. Relevant leaders of China University of Science and Technology, Chinese Academy of Sciences and other units signed the delivery certificate.
5. Beidou satellite navigation system
At 7: 52 on August 25th, 20 18, China successfully launched the 35th and 36th Beidou navigation satellites with the Long March 3B (and the upper stage of Expedition 1) in xichang satellite launch center.
These two satellites belong to medium-earth orbit satellites, and they are also the 11th and 12th networking satellites of China's Beidou-3 global system. At 22: 07 p.m. Beijing time 19, China used Long March 3B and Expedition 1 as the upper levels in xichang satellite launch center.
"One Arrow and Two Stars" successfully launched the 37th and 38th Beidou navigation satellites. These two satellites belong to medium-earth orbit satellites, namely 13 and 14 networking satellites of China Beidou-3 global system.
On these two Beidou navigation satellites, the standard equipment of the international search and rescue organization is also loaded for the first time, which will provide distress alarm and positioning services for users around the world. 20 18 12.27, the service scope of Beidou system expanded from the region to the whole world, and Beidou system officially entered the global era.
