Lingcha quasi-quasi-pangalactic
Tianhe sailed to the world
"Heavenly Boat"
A romantic name
Carried the Chinese
The dream of traveling in the vast universe
7 years ago today
Tianzhou-1 was successfully launched
As a cargo spaceship
It is affectionately called
"Courier Boy"
Today we will review it together
Wonderful moments of the Tianzhou-1 mission
At 19:41 on April 20, 2017, China's first cargo spacecraft Tianzhou-1 was launched from the Wenchang Space Launch Site, and China's manned space flight continued to write a new legend on the coast of the South China Sea.
The Long March-7 Yao-2 carrier rocket carrying the Tianzhou-1 cargo spacecraft was successfully launched at the Wenchang Cosmodrome on the mainland
After being launched into orbit, Tianzhou-1 and the Tiangong-2 space laboratory in orbit have successively carried out three rendezvous and docking and three in-orbit propellant replenishment, verifying a number of key technologies such as cargo transportation and in-orbit propellant replenishment, laying a solid foundation for the development and construction of the third step of the "three-step" development strategy of the continental manned space project. Not only that, Tianzhou-1 also successfully released a CubeSat in orbit.

Three rendezvous and docking
At 12:23 on April 22, 2017, the Tianzhou-1 cargo spacecraft and the Tiangong-2 space laboratory successfully completed the automatic rendezvous and docking. This is the first rendezvous and docking between Tiangong-2 and a cargo spacecraft since it was launched into orbit on September 15, 2016. Subsequently, Tianzhou-1 and Tiangong-2 entered the combined flight stage.

At 14:55 on June 19, 2017, the Tianzhou-1 cargo spacecraft completed the orbit and the second rendezvous and docking test with the Tiangong-2 space laboratory, consolidating the multi-directional space rendezvous technology of the spacecraft and is of great significance for the subsequent construction of the space station project.

At 23:58 on September 12, 2017, the Tianzhou-1 cargo spacecraft successfully completed the autonomous rapid rendezvous and docking test with the Tiangong-2 space laboratory, laying a more solid technical foundation for the follow-up development and construction of the mainland space station project.
Three propellants were added in orbit
At 19:07 on April 27, 2017, the Tianzhou-1 cargo spacecraft and the Tiangong-2 space laboratory successfully completed the first in-orbit propellant replenishment test. The breakthrough and mastery of the in-orbit propellant replenishment technology has filled the gap in the continental aerospace field and achieved a major technological leap in the field of space propulsion.

At 18:28 on June 15, 2017, the Tianzhou-1 cargo spacecraft and the Tiangong-2 space laboratory successfully completed the second in-orbit propellant replenishment test, which further verified the reliability of this key technology.
At 20:17 on September 16, 2017, the Tianzhou-1 cargo spacecraft and the Tiangong-2 space laboratory successfully completed the third and last in-orbit propellant replenishment test before deorbiting, further consolidating the relevant technical achievements.
Release the CubeSat
At 15:03 on August 1, 2017, the Tianzhou-1 cargo spacecraft successfully released a CubeSat in orbit, and then successfully captured the CubeSat on the ground.
This test is the first time that the mainland has released the CubeSat through the spacecraft system in orbit, and completed the separation and unlocking technology of non-pyrotechnic devices, the interface matching technology between the deployment launcher and the CubeSat, and the material and process guarantee technology verification of the deployment launcher manufacturing, laying a technical foundation for the subsequent deployment and launch of micro-nano satellites and in-orbit services on the continental space station.
Controlled derailment
At around 6:00 p.m. on September 22, 2017, Tianzhou-1 completed the space laboratory phase mission and subsequent expansion tests and re-entered the atmosphere in a controlled orbit.
Tianzhou-1 deorbited in a controlled manner
From Tianzhou-1
By this year will be launched
Tianzhou No. 8
The cargo ships of the mainland witnessed
From the space laboratory to the space station
Cargo spacecraft are becoming more and more able to "load"
The content of "bringing goods" is becoming more and more abundant
Seven years have passed
Across the world
Sailing on the heavenly river
The line is going far
future
Looking forward to the Tianzhou family
More exciting performances
