What should astronauts do if they encounter danger? These tactics can save lives

Shenzhou spacecraft is an astronaut into space and back to the earth "space shuttle bus", can take 3 astronauts, launch, Shenzhou spacecraft installed in the head of the launch vehicle, under the action of rocket thrust, by overcoming the earth's gravity continues to accelerate, and finally reach the corresponding orbit around the earth.

Ten million flights, safety first.

Protecting the safety of astronauts' lives is the highest creed, and at any stage of the Shenzhou XII mission, the Shenzhou team of the Five Academies of the Aerospace Science and Technology Group must have plans and measures to protect the safety of astronauts, and make every effort to ensure that astronauts safely travel between heaven and earth.

Let's see how many protections there are.

Launch phase

If a rocket fires, explodes, or otherwise fails unexpectedly, the Shenzhou spacecraft can quickly take astronauts out of the danger zone with the help of its upper escape tower. And rely on parachutes to achieve a safe landing, just like a fighter jet can be ejected by the emergency in the event of an emergency and major dangerous situation.

Flight phase

In the process of autonomous flight of the spacecraft, when there is an emergency fault such as fire in the cabin that threatens the life of the astronaut, the loss of pressure in the cabin, the Shenzhou spacecraft can return to the earth at any time, both under the control of the ground personnel to calculate the return parameters, or the spacecraft can be returned as the main control, without the participation of ground personnel.

Docking phase

In the process of automatic docking with the space station and the core module of the Shenzhou spacecraft, if the measurement and control equipment of the relative position and relative attitude fails, resulting in the inability to carry out automatic docking,

The Shenzhou spacecraft can be transferred to the astronauts to manually control the spacecraft, through the camera image, observe the space station docking cross target, manual docking.

Docking phase

During the docking of the space station, when an accident occurred on the space station that seriously threatened the lives of astronauts, resulting in the inability to continue the flight of the combination, the Shenzhou spacecraft had the ability to evacuate the space station at any time and return to The Earth safely.

Return to the stage

After separating from the space station, when the spacecraft return capsule rushed to the surface of the earth, the Shenzhou spacecraft was equipped with two sets of parachutes, and when one set had problems, the other set of parachutes could be up at any time to play a role in deceleration buffer.

Finally, when the Shenzhou spacecraft docked on the space station cannot return to The Earth for various reasons, we will activate the ace means in our hands, launch an emergency rescue spacecraft on the ground, and carry out a thousand miles rescue operation in the shortest possible time to ensure the safety of astronauts in the sky!
