Just now, China Aerospace once again created a world number one: Tianzhou 5 achieved 2-hour independent and fast docking for the first time. Compared with the 6-hour docking of Tianzhou 4, it is 4 hours faster, which is equivalent to a bit faster than the takeaway you ordered. foreign media rarely commented: China's space station has become the protagonist, and the United States has relaxed restrictions.

This is 14 hours faster than the Dragon Spaceship , which the United States is proud of. So how do we do this fast speed?

November 10, 2022 at 03:00, the Long March 7 Yaoliu rocket was launched from Wenchang and successfully entered the pre-determined orbit after 10 minutes. Unlike the last Tianzhou 4, this time the docking has been rapidly increased from 6.5 hours to 2 hours. It is amazing: China's aerospace can still hide things, which is too low-key.

has two major measures to achieve this goal:

first, further optimize the control strategy for long-distance docking;

reaches the predetermined track, long-distance guidance has multiple circles, changed to less than one circle; multiple track maneuvers are changed to two comprehensive track maneuvers; in layman's terms, it is directly turned and made a sharp turn.

Don’t underestimate this technology. In space environment, high-speed docking is a difficult problem. When space station is stationed, high-speed docking is achieved. Without 100% sure, you will not dare to do so. This part of the track adjustment and maneuvering saves more than 3 hours in total;

Second, reduces the confirmation process of close docking parking points;

is equivalent to direct access to high-speed rail, reducing multiple parking points set on the track and speeding up the approach speed, which shortens the time from the original 2 hours to 40 minutes.

This shows that although we already have such technology, we still use it carefully. Now the space station is about to enter the operation stage, and rapid docking can greatly solve the needs of space emergency missions.

This way, it saved 4.5 hours directly, which was 14 hours faster than the 16 hours of docking in the United States Dragon Spacecraft. In addition to achieving 2-hour fast docking for the first time, Tianzhou 5 has several firsts:

has achieved docking with the 80-ton "T-type combination" for the first time. This is equivalent to the docking of 6.7-ton small trucks and 100-ton kings on the highway, with extremely high difficulty coefficient;

for the first time when the space station is stationed, which means that in addition to independent docking, manual operations can also be used as backup;

is equipped with multiple test loads for the first time, that is, during the cargo transportation process, it is also equipped with 2 test loads, and a scientific experiment was conducted.

Behind such excellence is many "magic tools" to protect:

. The stable and high-speed Tianlian satellite is supported as communication support, plus high-definition camera, you can see real-time images throughout the whole process, and the live broadcast feels very strong!

. Behind the rapid docking of Tianzhou 5 is the independent transmission of measurement and control instructions, and a safe and efficient automatic program is very critical.

, the fuel cell power generation system equipped with will undergo the first test, which will provide energy guarantee for future lunar landing projects.

, Tianzhou 5 connects with the space station, adding many lighting equipment, and complete lighting conditions are available inside and outside the cabin.

As the luggage of the Shenzhou 15 astronaut during its orbit, it not only has rich local specialties, but will also continue to carry staple grain seeds, including rice, wheat, corn, etc., and will be directly bred on the space station to provide guarantees for a bumper agricultural harvest.

For China's aerospace progress, foreign media's remarks that like to pick on are gradually decreasing. After all, they have seen that China has become the first country in the universe to independently own space stations through independent research and development. China has become the protagonist and has invited many like-minded friends to develop together. It is really commendable.

While they were discussing, they also called on White House to consider lifting the restrictions on aerospace cooperation. After all, International Space Station has often leaked air, and the tape is difficult to stick. After it expires, there will be no space station available.

Everyone tells us that we have reached cooperation with 17 countries with an open attitude. If the United States lifts the ban, can we still have fun together?
