Tiangong-1's curtain call

On April 2, 2018, after accurate calculation and monitoring analysis by the Beijing Space Flight Control Center, Tiangong I re-entered the atmosphere at about 8:15 on the same day, landing in the central South Pacific Ocean, and finally achieved a perfect farewell with its gorgeous posture.

On September 29, 2011, at 21:16:03, Jiuquan Satellite Launch Center launched, from this moment on the sky belongs to China's target aircraft and space laboratory. The name "Tiangong" is mainly to cater to the diligent pursuit of unknown space in Chinese traditional mythology. The ancients regarded "Tiangong" as the most sacred place.

The main tasks of Tiangong-1 are: completing the space rendezvous and docking mission with Shenzhou-8; guaranteeing the life and work of astronauts during their short-term residence in orbit, ensuring the safety of astronauts; carrying out space applications (including space environment and space physical exploration), space science experiments, space medicine experiments and space station technology. A short-term manned and long-term unmanned space experiment platform was preliminarily established to accumulate experience for the construction of the space station.

Of course, the prerequisite for accomplishing these tasks is to have a "supernatural powers", how does Palace One have these skills? All this comes from its two functional modules: resource module and laboratory module.


Resource tank:

The main task of the resource module is to provide energy support for Tiangong-1's flight and control its flight attitude. All the equipment of Tiangong-1's power subsystem (solar wing) is in the resource cabin and includes fuel to power the aircraft. The 6 control moment gyroscopes in Tiangong-1's navigation and guidance system are also in the resource capsule. The purpose of the navigation and guidance system is to find the target when Tiangong-1 docks with the tracking aircraft, while the control moment gyroscope (CMG) controls the attitude of Tiangong-1 accurately.


Experimental cabin:

The open class of astronauts we are familiar with is carried out in the experimental module. Here the astronauts show us the miraculous phenomena of weightlessness, water droplets floating, candle burning (the shape of a flame is no longer in the shape of the ground, but close to the sphere) and so on, so that we can understand the difference between the space environment and the ground environment.

The experimental module is mainly responsible for astronauts' work, training and life. The experimental module is divided into the front cone section, the cylinder section and the rear cone section. After docking, astronauts enter the fully sealed front cone and cylinder for work and training, and some necessary life activities, sleep and so on are mostly carried out here. The rear unsealed rear cone section is equipped with regenerative birth protection equipment.

Of course, astronauts in the sky also need to complete certain exercises, the experimental cabin is equipped to make astronauts maintain a strong skeleton fitness zone, so that the astronauts'health can be guaranteed, so as to better complete the space mission.

Although the Chinese are more practical, there is no European and American equipment that "luxurious human experience", but in order to ensure the safety of astronauts, cabin cabin lines, sharp corners, core equipment are necessary to isolate from the astronauts, how is the palace one done? In this regard, the designer has adopted the strategy of "hiding" to decorate all the things that astronauts do not need. The equipment exposed to the outside is designed with rounded corners, which can avoid collision between astronauts and equipment and ensure safety.

After all, the space environment is different from the ground environment, we can not help but ask: in weightlessness, how do astronauts stop? The solution to this problem is the "hand and foot limiter". In Tiangong I, there are various hand-foot limiters beside each area. The total number of hand-foot limiters, which are about 30 cm long and made of brocade ribbon, are ingeniously placed around the bulkhead. This "small body" device has a great effect, it is the only "magic weapon" to ensure that astronauts in the state of weightlessness drift, easy to exert their hands and feet, is also the largest number of equipment in the cabin.

Of course, like us, astronauts must have their own entertainment life in the sky. In order to ensure the entertainment of astronauts, Tiangong-1 also provides the astronauts with a notebook computer for entertainment. Astronauts can use the notebook computer to surf the Internet, post micro-blogs, watch blockbusters, play some songs and music they like, or do it before going to bed. His entertainment activities.

In November 2011, Tiangong-1 docked successfully with Shenzhou-8, making China the third country in the world to master space rendezvous and docking technology independently. On June 18, 2012, the Shenzhou-9 spacecraft and the Tiangong-1 target spacecraft successfully rendezvous and dock, and three Chinese astronauts entered the orbiting vehicle for the first time.

In June 13, 2013, Shenzhou ten spacecraft successfully completed the automatic rendezvous and docking with Tiangong-1. After the return of Shenzhou ten spacecraft, Tiangong-1 completed its main mission. Of course, because the quality of the Chinese-made Tiangong-1 is so good that it is far from its age limit, the Space Academy has given it other tasks: testing the power generation capacity of solar cells, backup attitude measurement and control mode switching, 4B engine orbit change and a series of pull-offs and backup flight mode tests. Du explored the flight potential of Tiangong-1 and created better conditions for space environment exploration and earth observation.

Around 8:15 on April 2, Tiangong-1 re-entered the atmosphere and landed in the middle of the South Pacific Ocean. Most of the devices were ablated and destroyed during re-entry. It left a brilliant arc in the air. At this point, Tiangong-1 was a perfect curtain call for China's space station exploration program. The answer to beauty.
