China News Service, Beijing, December 10th (Ma Shuaisha Zheng Yingying) At 8:11 on December 10th, China used the Long March 4 Yiyao 47 carrier rocket at the Jiuquan Satellite Launch Center to successfully implement the 6th group of satellites. Send into the predetermined orbit.

The number of flights of China's Long March series of carrier rockets was officially refreshed to "400".

  The Long March 4B launch vehicle is a normal temperature liquid three-stage launch vehicle developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It has excellent performance and a wide range of uses. It has the ability to launch multiple types of satellites with different orbit requirements. It can be implemented as a single satellite Or multi-satellite launch, its sun-synchronous circular orbit carrying capacity can reach 2.5 tons (orbital height of 700 kilometers).

  The mission was only 18 days after the last launch of the Long March 4 series of carrier rockets.

This launch is the 84th launch of the Long March 4 series of carrier rockets and the 400th launch of the Long March series of carrier rockets.

  From the first flight of the Long March 1 carrier rocket on April 24, 1970 to the launch of the "Sino III" communications satellite by the Long March 3A carrier rocket on June 1, 2007, the Long March rocket achieved its first 100-round launch after 37 years. Milestone: On December 7, 2014, the Long March 4B carrier rocket successfully launched the China-Brazil Earth Resources Satellite. The Long March rocket achieved the second 100 rounds in 7 and a half years.

  On March 10, 2019, the Changsan B rocket successfully launched the Zhongxing 6C satellite. In more than 4 years, the Long March rocket achieved a leap from 200 to 300 rounds; December 10, 2021, the Long March 4B launch practice The mission of Group 6 and Group 05 satellites was successfully completed. In only 2 years and 9 months, the Long March rocket completed the launch of 100 rockets and reached the 400th milestone.

  After half a century, the Long March series of rockets have been completed all the way from nothing, from tandem to bundling, from one arrow to multiple stars, from launching satellites to launching spacecraft to moon probes and Mars probes. A major leap, especially in the recent 100 launches, China’s first space station core module, Chang'e-5 lunar probe, Tianwen-1 Mars probe, Shenzhou manned spacecraft, Tianzhou cargo spacecraft, Beidou-3 navigation satellite Such "heavy weapons of the country" were sent into space by the Long March series of rockets.

  It is reported that the Practice No. 6 Group 05 satellites launched this time were developed by the Eighth Academy and the Fifth Academy of China Aerospace Science and Technology Corporation for space environment exploration and new technology test verification.
