In the early morning of the 10th, China successfully launch the Tianzhou-4 cargo spacecraft into space with the Long March 7 carrier rocket, and the construction phase of the Chinese space station began.

At 1:56 a.m. on May 10, the Long March 7 carrier rocket lifted the Tianzhou-4 cargo spaceship into the air. About 10 minutes later, the spaceship and the rocket were successfully separated and entered the predetermined orbit. At 2:23, the spacecraft solar energy The windsurfing board started work smoothly and the launch was a complete success. This is the first launch in the construction phase of China's space station and the fourth expedition of the space station's cargo transportation system.

This is the first launch in the construction phase of China's space station and the fourth expedition of the space station's cargo transportation system.

The summer night is deep, and the coconut wind is blowing. Inside the Wenchang Space Launch Site, the Tianzhou-4 cargo spacecraft and the Long March-7 carrier rocket are ready for launch.

"Tianzhou-4 is China's first spacecraft to enter the construction phase of the space station. It has loaded more than 200 pieces (sets) of cargo, with a total weight of about 6,000 kilograms. It is responsible for providing material support for the Shenzhou 14 astronauts and the space station. tasks such as orbital operation support and space science experiments," said Dang Rong, deputy chief designer of the cargo spacecraft system of the Fifth Academy of Aerospace Science and Technology Group.

"Attention everyone, prepare in 30 minutes!" At 1:26, the commander of Launch Mission 01, Wang Yuliang, resounded through the launch site.

Wenchang Space Launch Site is the only coastal launch site in China and is affiliated to the Xichang Satellite Launch Center. Since 2017, the Tianzhou series of cargo spaceships have successively flown from here to space.

"5, 4, 3, 2, 1! Ignite!" At 1:56, accompanied by a loud rumbling, the Long March 7 carrier rocket lifted the Tianzhou 4 cargo spacecraft into the air, drawing a gorgeous line in the night sky traces of.

The Long March 7 is China's new generation of medium-size launch vehicles. This is the first time that the Long March 7 has completed the test and launch within one month.

At 1:56 a.m. on May 10, the Long March 7 carrier rocket lifted the Tianzhou-4 cargo spaceship into the air. About 10 minutes later, the spaceship and the rocket were successfully separated and entered the predetermined orbit. At 2:23, the spacecraft solar energy The windsurfing board started work smoothly and the launch was a complete success. This is the first launch in the construction phase of China's space station and the fourth expedition of the space station's cargo transportation system.

"This time, the test and launch cycle of the rocket is 4 days shorter than that of the Tianzhou-3 mission," said Shen Dan, deputy director of the Long March 7 Launch Vehicle Model Office of the Aerospace Science and Technology Group.
About 10 minutes later, the spacecraft and the rocket successfully separated and entered the predetermined orbit. At 2:23, the solar panels of the spacecraft started to work smoothly, and the launch was a complete success.

So far, the curtain of the construction phase of China's space station has officially opened, and the key battle to achieve the "three-step" strategic goal of China's manned space project has begun.

At this moment, the combination of Tianhe core module and Tianzhou-3 of the space station is flying at a height of 400 kilometers in space, waiting for new members to join.
