103!new record

Refresh! The China Long March series of carrier rockets set a new record of successful success!

"Global Times" reporter learned from the China Aerospace Science and Technology Group on the 20th that at 1:37 on August 20, the Long March 2 Ding Yunzai Rockets successfully launched a remote sensing 35 group of satellite A and B stars at the Xichang Satellite Launch Center. , C star. The successful success of this launching task marks the success of the China Long March series of launch vehicles achieved 103 consecutive launch, breaking the record of successful launch successfully before.

According to a reporter from the Global Times, the satellite A star, B -star, and C star of the remote sensing 35 of the remote sensing 35 were mainly used in scientific tests, land and resources census, agricultural product estimation, and disaster prevention and mitigation. Among them, A star and B star were developed by the Fifth Hospital of China Aerospace Science and Technology Group; C star and the Rockets were developed by the Eighth Hospital of China Aerospace Technology Group.

From October 20, 1996, the two -ding rocket successfully launched the 17th return satellite, to August 6, 2011, and the long four -B rocket successfully launched the Ocean No. 2 satellite. Essence

However, the high -risk traits of the space industry mean that risks and challenges exist, and the subsequent launch failure also sounded the alarm for the astronauts. To this end, China Aerospace Science and Technology Group conscientiously carried out comprehensive quality review and review, opposite to three, and fully guarded the production quality bottom line and red line. After unremitting efforts, the quality work has been significantly improved. A spokesperson for Aerospace Technology Group said in an interview with the media that this time it was successful for 103 consecutive launch, only 830 days, the average launch task was completed every 8 days, and it created a day for a day. The new record of successful launch in a row.

During this period, the Long March Series Loe Rockets will be Tianhe's core compartment, Tianzhou freight ship, Shenzhou carried manned spacecraft, Chang'e 5 moon detector, Tianwen No. 1 Mars probe, Beidou 3 navigation satellite and other "heavy weapons" Send into space; Long March 8th Yaoya Rocket "One Arrow and 22 Stars" was launched successfully, setting up a new benchmark for one -arrow multi -star launch in my country; the "Ask Heaven" experimental cabin is currently the largest single spacecraft in my country, weighing about 23.2 tons, which The Long March 5 Yao Three Rockets lift off; the new model of the Long March 5, the Long March 6, and the Long March 8th, etc. The new generation of carrier rockets has gradually improved, covering low, medium, and high tracks. With various types of spacecraft, the Chinese people explore the universe to be more stable and farther.

"The Long March Rockets can still maintain such a high success rate under the situation of high -density launch. It is the contradictions that China Aerospace Science and Technology Group has worked hard in the process of reform and development over the past three years. The development of high efficiency and high efficiency 'has achieved obvious results. "Wu Yansheng, secretary of the Party Group and chairman of the China Aerospace Science and Technology Group, said.

A spokesman for Aerospace Science and Technology Group said that at present, China Aerospace has entered the normal stage of high -density launch. The Long March series of launch -carrier rockets, as the main force of my country's aerospace industry, has performed 433 (including this) launch task, and has put more than 700 more than 700. The spacecraft was sent to space, and this year the Aerospace Science and Technology Group plans to arrange more than 50 space launch missions. The vigorous development of the aerospace industry has effectively proved the rapid jumping of my country's scientific and technological level and comprehensive national strength.

At present, more than 10 types of Long March Rockets that are in service can not only launch satellites, space stations, manned/cargo spacecraft to high, high, and low -level earth orbits, but also have the ability to launch unmanned deep space detectors, and the strength has reached the world's advanced level.

In the 103 consecutive launch of the Long March Rockets, there are "gold medals" veterans such as "Long March 2", "Long March 3" and "Long March 4", as well as "Long March 5", "Long March 6", "Long March Seven The Long March "New Generation" such as "Long March 8" and "Long March 11".

In addition, my country is currently developing a new generation of manned carrier rockets and heavy -duty carrier rockets. These rockets will undertake the tasks such as the launch of the moon landing, Mars detection, Jupiter detection, and asteroid detection to support the pace of Chinese people to explore space stable and far away.

A spokesperson for Aerospace Science and Technology Group also pointed out that at present, the Aerospace Technology Group is organizing research and analysis and special research on the development and launch price of carrier rockets at home and abroad. The results show that my country ’s Long March series of carrier rockets have high reliability and excellent cost -effectiveness. , Still have competitive advantages.

First of all, the prices of the Long March Series Loe Rockets are far lower than that of a one -time carrier rocket abroad, such as "Cosmic God 5", "Delta 4H"; Compared with the 9 Rockets, the "Long March 2" "Long March 2" and "Long March 2 Ding" and the Long March 5 load rocket are also comparable to them. The launch price of the No. 1 carrier rocket is still lower than that of the Falcon 9 Rockets. Of course, through reusing technology, the cost of the Falcon 9 rocket is greatly reduced, and its market price still has a large price reduction space.

Judging from the situation of foreign countries, especially the United States, increasing the rocket's carrier capacity and the realization of rocket reuse are important technical means to improve the launch of the carrier rocket into the space efficiency and efficiency. To this end, the Aerospace Technology Group will follow up three aspects.

The first is to accelerate the development of reusable use of carrier rocket technology, and to achieve engineering applications for reuse technology as soon as possible; the second is to accelerate the key technical research and plan argumentation of heavy -duty carrier rockets, realize 100 tons of carrier capacity at an early date, greatly enhance my country to enter space and use it in China and use it. The ability of space; third, for the active carrier rocket, it is necessary to continue to carry out performance improvement, process optimization, product unified type, cost control and other work, steadily improve the efficiency and efficiency of active carrier rockets, provide high -quality launch services for various aerospace weapons EssenceLong Lehao, an expert in the first house of China Aerospace Science and Technology Group and an academician of the Chinese Academy of Engineering, said that with the continuous service, maturity and growth of the new generation of the Long March Rockets, the new and old rockets will continue to be high -quality, highly reliable and continuous successful successful success.Go forward, achieve comprehensive alternation, continue to safely and reliable to send various aerospace devices to the predetermined track, contribute to the construction of a space -to -be -aerospace country, and provide more help for promoting national economic development, serving the national livelihood and creating a better life.
