Danning our country's heavy weapon: Ask the Sky Experimental Cool: Explore the "All -around" laboratory of the mysterious space of space

On July 24, 2022, the Chinese Space Home for the first time ushered in a spacecraft's visit to the spacecraft with a spacecraft.

On that day, the Chinese Space Station asked the Tiangtian Experimental Curm "Ride" Long March 5 Yao Three Lauret Rockets flying into the sky and accurately entered the scheduled track. Later, successfully connected to the front port of the heavens and the core compartment combination.

This is a "big guy" with a launch weight of 23 tons. "This head and weight are equivalent to a compartment of the Beijing Metro Line 13 train." Zhang Ye, the chief designer of the Fifth Hospital of Aerospace Science and Technology Group, asked for precise portraits for it.

Indeed, it is the heaviest aircraft active aircraft in the world in the world. Including the three -cabin section of the working cabin, the air gate, and the resource cabin, the total length is 17.9 meters and the diameter is 4.2 meters.

Don't look at it big, this "big guy" is a smart "all -round" player that integrates platform functions and test loads.

On the function of the platform, asking the Tianjin experimental compartment and the core compartment of the sky and the core compartment are backup. The key platform functions are the same, which can completely cover the work requirements of the space station combination. Zhang Yan said: "This is like Tianhe's core cabin‘ want to rest ’. Asked the experimental cabin to top it immediately,‘ take you to fly ’!”

On the test load function, I asked the Tianjin experimental cabin to carry multiple experimental cabinets and the off -cabin load adapter, and moved the large scientific laboratories to space. Because the space station can provide a special research environment such as long -term micro -gravity and radiation, scientists may find the essential laws of substances covered by gravity on the earth. Moreover, there are "express brothers" Tianzhou freight ships transported round trip between heaven and earth. In the future, Chinese people can conduct large -scale space science experiments in space!

But science laboratories in space are unusual. As the first scientific experimental cabin of the second cabin of China Space Station, there are many scientific experimental cabinets with multiple widths of about 1 meter, 1.8 meters high, and 0.8 meters deep in the Tiangan experimental cabin, including life ecological experimental cabinets, biotechnology experimental cabinets, and biotechnology experimental cabinets, and Severe scientific experimental cabinets, scientific glove boxes, low temperature storage cabinets, etc.

Each scientific experimental cabinet is a comprehensive laboratory. "It is equivalent to integrated the experimental equipment of the dozens of square meters on the ground to a 2 -cubic meter experimental cabinet space." The deputy chief planner of the manned aerospace engineering space application system, the Chinese Academy of Sciences Space Application Center Integrated Technology Center Director Wang Ke said.

"In the future, I will focus on the research of life sciences and biotechnology in the testers. It will conduct research in the fields of spatial life sciences and biotechnology, micro -gravity physics science, spatial materials science, new space technology and application trials to explore unknown." Lu Congmin, deputy chief planner of manned space engineering space application system and researcher of the Space Application Center of the Chinese Academy of Sciences, told reporters.

There is also a "locker room" in the experimental compartment, which is round, large and superior in the outside world. With it, the astronauts will be more calm and stretched when they are preparing for the cabin and returning outside the cabin. In the future, it will become the main outlet channel of the entire space station system.

Similar to the sky and the core cabin, the questioning of the Tiangtian experimental cabin is also equipped with a robotic arm. This robotic arm is small and highly accurate, which is convenient for fine operations. It can also form a combination arm with the core cabin large robotic arm to carry out more out -of -class operations.

"By then, the combined arm can crawl between the Tianhe, Ask Heaven, and Mengtian Three Class combinations of the space station. The scientific experimental load equipped will be accurately delivered to the corresponding standard load interface position through the robotic arm. In this way, it is "plugged in and players, and the spacer is no longer needed to operate artificial operations."

The "all -round" question cabin also has a new mission- "Space New Classroom", and the new space teaching will be carried out here.

According to the mission schedule, another 20 -ton spacecraft at the China Space Station -Mengtian Experimental Currency will be launched in October this year. At that time, the three compilers of the core compartment, the test compartment, and the Dream Tianyian experimental cabin will form the basic configuration of the "T". China Space Standing will be finally completed in the rail construction.

What is even more exciting is that at the end of this year, the first "Space Society" of Shenzhou 14th and 15th Aerospace Commissioner. At that moment, the warmth, comfort, safe and efficient, and cutting -edge space home of the Chinese will bring us more excitement and touch.
