In the telescope, it is all beautiful
Just tonight, China's most traditional Mid-Autumn Festival, we can really eat moon cakes.
At 22:04, China will launch the first truly space laboratory, Tiangong 2, and it is said to be the most beautiful space laboratory for the astronauts to live in for a long time (without planting potatoes).
According to statistics, the Tiangong-2 space laboratory is equipped with the world's first space cold atomic clock, the world's first empty space quantum key distribution test and 14 other space application load black technologies; it will carry out more than 10 space science and application projects and is a manned spaceflight. The most frequently used projects in the previous missions involved various fields such as microgravity fluid physics, space materials science, space life sciences, space astronomy exploration, space environment monitoring, earth observation and earth science research, and new technology experiments.
The 22:04 pm on the full moon night will launch the “Tian Gong 2†on time and it will be very greasy. If it is not clear in advance, I’m afraid it’s hard for Ti Da Ti media to call the most grievous technology media, and follow the titanium media first. Xiao Bian casually looks at the black technology devices on the "Sky II":
Pursuit of extremely precise amount of days
The "space cold atomic clock" developed by the Shanghai Institute of Optics and Technology of the Chinese Academy of Sciences will be launched with the launch of "Temple II". It will become the world's first "space cold atomic clock" that runs in orbit and carries out scientific experiments. It is also the highest in space at present. Accurate atomic clock.
The most accurate timepiece we use every day is about 1 minute per year. Since the atomic clock, the accuracy of human timing has been growing at an almost-magnitude-per-a-decade rate. By the end of the 20th century, it has reached a magnitude of 10^14, that is, an error of about For 1 second / 3 million years, and the cold atomic clock carried on "Tiangong 2", the time error has been reduced to 1 second / 300 million years of error;
Variety King Kong
The research on the issues related to the thermocapillary convection stability of the large Prandtl bridge was carried out to study the mechanism of the instability of thermocapillary convection under the spatial microgravity environment. The cognitive field of fluid mechanics was expanded and research results with international advanced level were obtained. Breakthroughs and master key technologies in space experiments such as bridge construction, liquid surface maintenance, and instability reconstruction under microgravity environment, to further enhance the space experiment capability and technical level of microgravity fluid science in China.
Series hero materials
The mission of this platform is to study the basic principles of semiconductor optoelectronic materials, metal alloys and metastable materials, nano-materials, and composite materials, and to reveal the laws of physical and chemical processes of materials that are difficult to obtain under the ground-weight environment. It is expected that high-quality samples of space materials will be available to obtain valuable scientific research results as the structure, function, and process parameters of the model materials.
Temple of Heaven
The upcoming furnace is a set of integrated material experimental devices (abbreviated as “experimental devicesâ€) that have been developed by engineers after more than three years of research.
This set of experimental devices consists of three stand-alone machines, the "Material Experimental Furnace" ("The Furnace"), the "Material Electronic Control Box" and the "Material Sample Tool Bag." The total weight of the whole device is about 27.6kg, the maximum power consumption is less than 200W (and the power of general electric kettle is also 1000~1800W), which is equivalent to two 100W incandescent lamps, but it can realize the maximum furnace temperature of 950°C in a vacuum environment. Not amazing?
The feeling of the sea
The “Tiangong 2†three-dimensional imaging microwave altimeter is the first time in the world that a microwave altimeter capable of three-dimensional imaging can be measured with a wide swath height. It adopts small-angle, high-precision interferometry technology to accurately obtain interference fringe information on the sea surface, and then obtains a three-dimensional sea surface morphology. After complex calibration, a sea-level height measurement within a wide swathe width is finally obtained.
Heavenly Guardian
"Tian Gong II" satellite is a micro-nano satellite and it is the "Tian Gong II" trial.
Part of the business. Accompanied by the satellite developed by the Shanghai Center for Microsatellite Engineering, the miniaturization, lightweight, and high functional density design were adopted. "Tiangong 2" is equipped with a number of test payloads along with the satellites, and has a strong ability to change orbits. It has the flexibility and mobility to carry out space missions.
"Tiangong 2" will carry out experiments such as overflight observations of space assemblies during orbital missions, provide support for technical tests of the main spacecraft, and expand the application of space technology.
A bee who prefers a Gamma storm
The "Tianji" telescope is a gamma ray polarization detector mounted on the Tiangong-2 space laboratory and is a Sino-European international cooperation project.
The main scientific goal of the “Tianji†telescope is to detect and study sudden gamma-ray bursts in the distant universe, and for the first time in the world to measure the polarization properties of gamma-rays with high precision and systematically, in order to deeply study the evolution of stars. The formation of black holes, the formation of black holes, and the physical mechanisms of the outbreak of Gamma bursts have made important contributions to better understanding the most dramatic outbreaks in this universe in the extreme astrophysical environment.
Feelings of Heaven and Feelings of Heaven
The space environment sub-system (full name: space environment monitoring and physical detection sub-system) is mainly used to monitor the radiation environment and atmospheric environment on the orbit of “Tiangong 2†in real time, and realize the intensities of charged particles such as electrons and protons outside the cabin in 16 directions. And energy spectrum monitoring, as well as the orbital atmospheric density, composition and its spatio-temporal changes and monitoring of the effects of space environmental pollution.
Modern mini space greenhouse
With the deepening of human space activities, humans need to fly out of the earth and live and work in extraterrestrial space for a long time. Green plants provide essential food and oxygen for humans and animals.
In the "Tiangong II" space laboratory, two representative plants, Arabidopsis thaliana and rice cultivation experiments will be carried out, focusing on exploring techniques and methods for controlling the flowering and planting of plants in the space environment. The foundation of the life and ecological support system necessary for long-term space survival. The Advanced Plant Incubator provided by the Shanghai Institute of Technical Physics, Chinese Academy of Sciences, has an on-orbit culture unit and sample return unit that provides the necessary moisture supply and light control and temperature control for plant growth, and provides real-time visible light images and fluorescence image acquisition functions. The modern mini space greenhouse provides support for the study of the growth and development of plants in space.
Tiangong's cutting-edge "digital camera"
As a cutting-edge “digital camera†in space laboratories, wide-band imaging spectrometers have a fairly deep “internal forceâ€. The camera was installed on the "belly" of the space laboratory observation surface. With it, the "Tiangong II" can be said to have the "eye-catching" ability to see the ocean, see the atmosphere, everything is proficient.
The secret cannot be revealed
Developed the "Tiangong 2" payload "quantum key distribution test space terminal". By using the high-precision auto-tracking (ATP) system and the quantum key distribution ground terminal, a quantum channel is established between the ground station and the target aircraft, and an air-ground quantum key distribution experiment is performed on this basis. The goal is to achieve the world's first space-ground quantum key distribution demonstration experiment based on a manned space platform. It lays the foundation for the construction of a space-based quantum secure communication between manned space and the future practical use of a wide-area quantum secret communication network.
Let's take a look at the true features of "Tian Gong II"It is said that another highlight of this "Temple II" was the change from the "Rubber House" of Tiangong 1 to the "Mansion" of Tiangong 2 and became a truly space station suitable for living. How luxurious? "Temple II" is like a long?

The overall appearance of "Temple II"
According to Liao Jianlin, deputy chief architect of the space laboratory system of the China Aerospace Science and Technology Corporation, he introduced to the media: "Temple II" is not a repeat of the simple "Temple One", and many new design tasks were carried out around the mission, including The mid-term residency of the astronauts, we carry out some design of astronaut comfort in this cabin. Including the interior, with some hard, soft handrails, better than "Tiangong 1".
It is worth mentioning that the system design of “Tian Gong 2†is modular, which means that it can quickly replace and repair on-orbit when it is problematic, which is the first in the field of domestic space.
After the launch of the Tiangong-2 space laboratory, two astronauts will be admitted to Tiangong. They will work and live there for 30 days, verifying that the astronauts are on track in mid-term. This is also the longest mission of manned flight time in China so far.
Living in a weightless environment for 30 days is not an easy task. For this reason, "Tian Gong 2" has added a lot of intimate designs internally, which is more convenient for the astronaut's work and life:
1. The first use of a multi-function platform that can be expanded. The astronauts can write, eat, and do scientific experiments on the books.
2. The communication is equipped with a Bluetooth headset and a Bluetooth stereo for the astronaut.
3, replace the carpet with the floor.
4. In-cabin lighting is in beige shades, brightness can be adjusted manually, and bed lights are installed for each astronaut.
In fact, the 30-day space residency is not only a test for the astronauts themselves, but also a new challenge to China’s manned space technology. How to provide an environment suitable for people for a long time, and how to provide supplies including water for a long time will be verified in the “Tiangong 2†mission.
All in all, in short, "Tian Gong II" is China's first space laboratory in the true sense of the word, and the experimental project it carried has reached an unprecedented 14 items. It will soon become China's "busiest" space laboratory.
