Discovery for the first time!If you ask the Tiangan Experimental Cels, there is no successful track ...

July 17, 2022

After the test verification is completed by Tianzhou 3

Separation from the heavens and the core cabin

For the visit, the interface of the interface of the interview with the interview

After separation

Tianzhou II

It was in the next 10 days

Flying with the space station on a notable track

Until I see

Ask the Tianjie Experimental Class and the Heavenly and Core Class Combination

After the docking

It just waved farewell with the space station

After the test compartment was on track, it successfully completed the status settings. At 3:13 on July 25, 2022, Beijing time, it was successfully connected to the front port of Tianhe's core compartment. Image source: China Manned Aerospace

11:31 on July 27, Beijing time

Tianzhou -3 freight ship is controlled and then entered the atmosphere

Most of the devices of the spacecraft have been destructive

A small amount of wreckage falls into the southern Pacific reservation safety waters

Behind this watch

Is there any unknown mission?

Reporter from the Fifth Hospital of China Aerospace Science and Technology Group

The overall design department learned

Compared with Tianzhou II

Tianzhou 3 is also accompanied by 299 days with the space station

But there are two more new tasks

The first is to verify the accompanying ability with the sky and the core cabin

At the same time, leave the docking safety channel for the test compartment

Second, if you ask the Tiangan Experimental Curring Card to track an abnormal situation

It will be connected to the core compartment after the implementation of the track change

Assist in Tianhe's core compartment to complete the docking with the experimental compartment

To build a space station

Contribute your last strength

In order to ensure the safety accompaniment with the sky and the core cabin

The security docking of the test compartment

Tianzhou II

Multiple aspects of technical detail adjustment

First adjust the evacuation speed

Eliminate the sky and the core cabin

The impact of rail changes on relative distance

Followed by adjusting Tianzhou 3

The attitude control mode during the accompaniment period

Eliminate the uncertainty of the distribution of goods

The effect of attracting posture control on the relative distance

In addition, the meeting control strategy was adjusted

Make

It can be at the fastest speed, minimum fuel

Complete the docking with the core compartment

If you ask the sky launch compartment emitter, there is an accident

Can't rely on Tianzhou 3 to turn the tide

The cooperation of the carrier rocket also needs to

The reporter learned from the first hospital of Aerospace Science and Technology Group

If there is a problem with the launch, it cannot reach the scheduled orbit

Long March 5 Y Yao Lae Rocket

Will strive to ask the Tian Tian experimental cabin to a lower track

Help it meet as much as possible with Tianhe's core cabin

Of course, whether it is Tianzhou II

Still the "hidden function" of the Long March 5 Yao Three Load Rockets

It's just this task

One of the thousands of emergency plans

With the launch of the experimental compartment of the sky

The successful success of the docking task

These plans will continue to guard silently

Tianzhou II

China Aerospace

Behind the continuous achievement

It is the aerospace people who are not afraid of difficulties

Payment and dedication of courage to challenge

Let us like the astronauts!
