The latest current affairs and politics in p>212: Shenzhou IX will carry the first female astronaut and be launched on 16th

On June 9th, a spokesman for China's manned spaceflight project announced that the Shenzhou IX spacecraft had been vertically transferred from the technical area of Jiuquan Satellite Launch Center to the launching area. According to authoritative experts, Shenzhou-9 has confirmed the first launch window and will be launched on the afternoon of the 16th of this month. Shenzhou 9 will carry a female astronaut into space for the first time.

A spokesman for China's manned spaceflight project announced on the 9th that the Shenzhou-9 spacecraft and the Long March-2 F remote-9 rocket assembly, which carried out China's first manned rendezvous and docking mission, have been vertically transferred from the technical area of Jiuquan Satellite Launch Center's manned space launch site to the launch area. This indicates that Tiangong-1 and Shenzhou-9 manned rendezvous and docking missions have entered the final preparation stage. According to the plan, the Shenzhou-9 spacecraft will be launched in mid-June.

After the propellant filling, Shenzhou-9 spacecraft was hoisted and docked with the launch vehicle to form a complete assembly. At 1: 3 on the 9th, the mobile launch platform carrying the assembly drove out of the vertical assembly test workshop of the manned space launch site and was safely transported to the launch tower. Then, the spacecraft and rocket function tests and the joint tests of man, ship, arrow and ground will be carried out one after another.

The spokesman said that the Tiangong-1 target aircraft was lowered to the docking orbit in early June, and it was running normally in orbit. At present, preparations for the manned rendezvous and docking mission between Tiangong-1 and Shenzhou-9 are progressing smoothly.

The reporter interviewed an authoritative expert at the launch tower yesterday. He said: Shenzhou-9 has confirmed the first launch window and will launch on the afternoon of 16th of this month. This is different from the time when it was launched at night most of the time. According to experts, to determine this window, first of all, this time it is manned rendezvous and docking, manned space flight, and human life is crucial. In case of an accident, effective search and rescue work can be carried out during the day; In addition, the Tiangong-1 target aircraft was calculated to be in the scheduled docking orbit at that moment after descending orbit, waiting for the rendezvous and docking of Shenzhou-9. < P > In June, the Gobi Desert was sunny and the sky was clear, and Wan Li was clear.

At 1: 3 yesterday, the six lifting doors of the vertical assembly test workshop of Jiuquan Satellite Launch Center were completely opened. The mobile launch platform carrying the Shenzhou-9 spacecraft and the Long March II F remote nine rocket assembly, driven by the power car, slowly drove to the launch tower along the seamless welded heavy rail with a length of 1,5 meters and a width of 2 meters. This indicates that the rendezvous and docking mission between Tiangong-1 and Shenzhou-9 spacecraft has entered the final preparation stage.

Transshipment begins

A big step in China's manned space flight history

The mobile launch platform moves forward at a speed of 28m/min. Zhou Jianping, the chief designer of manned spaceflight project, who walked in front of the mobile launch platform, became the focus of journalists' pursuit. "Shenzhou-9 will rendezvous and dock with Tiangong-1 target aircraft for the first time in China, which means that China's spacecraft will become a real manned space shuttle tool, which can send people to space stations or space laboratories. This will be a significant step in the history of manned space flight in China. "

From Shenzhou-1 to Shenzhou-9, Zhou Jianping witnessed the transshipment before the launch of all the spaceships. "I am very willing to walk the 1,5m with the spaceships and rockets. Don't you think this is a very important road? "

During the transshipment,

Children outside the track are running

Along the transshipment track, red flags are flying in the wind. The scene was crowded with staff of major system test teams and nearby residents, and this was their first time to watch the transshipment in the summer desert.

"Today, the temperature is rising rapidly, from 19 degrees Celsius in the morning to 3 degrees Celsius now, so the wind of thermal disturbance is a little strong, but all this is under control." Yang Jiannong, deputy director of the Experimental Technology Department of Jiuquan Satellite Launch Center, is leading several staff members to provide meteorological support along the way.

"here comes the rocket!" On the lawn outside the transfer track, a group of children are running to their heart's content.

The transshipment was successful

The ship's arrow was "hugged" in the arms

It passed the large placard of "meticulous and minute-by-minute", and the ship's arrow tower assembly was about to reach the launch tower.

"In order to meet the launch needs of Shenzhou-9 spacecraft, we optimized the air-conditioning and fire-fighting systems in the launch tower, and improved the reliability of equipment and facilities." Zhang Yonghua, deputy chief designer of the launch site system and senior engineer of Beijing Special Engineering Design and Research Institute, said, "All work is focused on manned to ensure the safety of astronauts." The combination of ship and arrow reaches the launch tower accurately, and the movable launch platform automatically centers and locks. The open steel arms of the tower slowly close together, and the ship-arrow combination is tightly "hugged" in the arms.

At this time, the Tiangong-1 target aircraft has been in orbit for 254 days and is waiting for the arrival of Shenzhou-9 in space.

Four highlights of Shenzhou-9 launch

1 Manual rendezvous and docking

Three astronauts will manually rendezvous and dock in space for the first time. "The success rate of manual docking is higher than that of automatic docking, but it is a greater test for astronauts." Jiao Weixin, a professor at the School of Earth and Space Sciences at Peking University, said.

\2 Chinese female astronauts

China will have a female astronaut in space for the first time. "Manned space flight without female astronauts is incomplete." Jiao Weixin said.

3 Stay longer

Astronauts will stay in space for longer. Jiao Weixin predicts that three astronauts will stay in space for 1-2 days, which is the longest stay of Shenzhou series spacecraft.

4 experimental operation

After the docking of Shenzhou-9 and Tiangong-1, the astronauts will carry out experimental operation in Tiangong-1, which is the first time in China's space history.

Two months of "seclusion"

Yesterday, it was officially revealed for hundreds of tests.

The staff of the launch center introduced that the Long March II F carrier rocket used to launch the Shenzhou-9 spacecraft arrived at Jiuquan Satellite Launch Center on the 9th of last month, and all kinds of test preparations were made at the launch site.

Since April 9th, all the tests of Shenzhou-9 spacecraft entering Jiuquan Satellite Launch Center have progressed smoothly. The launch test station has comprehensively inspected the facilities and equipment of manned space launch site, and conducted targeted training for personnel. Before leaving the factory, the spacecraft has gone through the test contents including the physiological signal test of the crew combination, the inspection of the emergency rescue subsystem, the fuel performance and the temperature control system. The launch site has the ability to carry out manned rendezvous and docking missions. Since the spacecraft and rockets arrived at the launch base, various system tests and overall tests have been carried out hundreds of times.
