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.

On April 25, according to CCTV news, yesterday was the seventh China Space Day. As of now, the Chang'e-4 lander and Yutu-2 lunar rover, which are performing missions on the far side of the moon, are in good condition. Among them, the Yutu-2 lunar rover is dormant on the 41st moon night, with a cumulative mileage of 1142.387 meters.

On Mars, the Zhurong rover has traveled more than 1.9 kilometers, and the Tianwen-1 orbiter is also carrying out orbital exploration around Mars, and will soon achieve global coverage of Mars. At present, the two devices are in good condition, and a large amount of scientific detection data has been obtained.

Our own Tianshanggongque, the Chinese space station, will also complete its on-orbit construction this year. The combination of the Tianhe core module and the Tianzhou-3 cargo spacecraft currently in space is in normal condition and the on-orbit operating parameters are stable.

Yutu-2 is a lunar rover for the Chang'e-4 mission. It separated from the Chang'e-4 lander at 22:22 on January 3, 2019, and arrived at the back of the moon. The first landing on the back of the moon has become another milestone in the development of China's aerospace industry.

Luo Junjie, spokesman for the Ministry of Industry and Information Technology, said at the meeting that we will moderately speed up the development of domestic resources, and work with relevant departments to resolutely crack down on unfair competition such as hoarding and price gouging, and promote the return of new energy vehicle raw material prices to rationality as soon as possible. Give full play to the role of a smooth and coordinated platform for the supply chain of the automobile industry chain, and strive to ensure the production and supply of parts and components. We should also pay attention to strengthening the overall arrangement of resources, and resolutely curb blind investment and duplication of construction.

Luo Junjie also said that, from a comprehensive perspective, my country's new energy vehicle industry has entered a new stage of large-scale and rapid development, and it is expected that it will maintain a rapid development trend this year. We will study and clarify support policies such as the continuation of car purchase tax incentives as soon as possible, and optimize the "double points" management method. According to the requirements of the "1+N" policy system of the dual carbon goals, organize the compilation of a low-carbon development roadmap for the automobile industry and provide guidance for industry enterprises.

In addition, Luo Junjie said that we will continue to carry out the pilot work of new energy vehicles to the countryside and the battery swap mode, and start the pilot city of full electrification of public vehicles. We will work with relevant departments to accelerate the construction of charging and swapping facilities, promote information sharing and unified settlement, and continuously improve the convenience of charging and swapping.

Recently, BYD Auto officially announced that according to its strategic development needs, it will stop the production of fuel vehicles from March 2022.

BYD said, "In the future, BYD will focus on pure electric and plug-in hybrid vehicles in the automotive sector. This marks that BYD has become the first car company in the world to officially announce the discontinuation of fuel vehicles. At the same time, BYD will continue to provide Some fuel vehicle customers continue to provide comprehensive services and after-sales guarantees, as well as spare parts supply throughout the life cycle to ensure worry-free travel.”

According to BYD's sales report, it sold a total of 104,900 vehicles in March, all of which were new energy vehicles, and did not produce and sell gasoline vehicles.

The reporter learned from the press conference on the 23rd that a black box of China Eastern Airlines flight MU5735 was found on the 23rd.

A reporter from People's Daily learned from the press conference that a black box of the crashed plane has been found at the accident site. Since the found black box is seriously damaged, it is not certain whether it is a data recorder (FDR) or a cockpit voice recorder (CVR). ).
