CTOnews.com November 28 news, Shenzhou 15 manned spacecraft aimed at November 29 Beijing time at 23:08 launch, flight crew by astronauts Fei Junlong, Deng Qingming, Zhang Liu composed, Fei Junlong as commander.

According to CCTV news report, the Long March 2F remote 15 rocket launched by Shenzhou 15 spacecraft is not only a brand-new batch of Long March 2F rocket, but also the brand-new ground equipment matching with the launch site system for the first time. It can be said that both new batches of rockets and brand-new launching equipment have been used. Compared with the previous rocket, it has been comprehensively upgraded and optimized.

It is reported that compared with the Long March 2F remote 14 rocket, the remote 15 rocket has carried out 45 technical state improvements, which comprehensively improved the accuracy of the rocket orbit on the premise of improving safety, so that the subsequent orbit and rendezvous and docking tasks can be more smooth. In addition to the comprehensive upgrade of the rocket, the ground equipment has also improved 11 technical conditions, improving the reliability, safety and anti-risk capability of the rocket, and the pre-launch process operation is more automated, reducing the risk of human error.

Long March 2F is China's first manned rocket, known as "China's God Arrow." As China's first manned rocket, the Chang-2F rocket has participated in every step of the "three-step" strategy of China's manned space project during the past 30 years, and has carried out all manned spacecraft and target vehicle launch missions from Shenzhou-1 to now. Since its maiden flight in 1999, the Long March 2F carrier rocket has successfully launched 14 Shenzhou spacecraft and two space laboratories, including nine manned launch missions.

Unlike other types of rockets, the Long March II F rocket, as a manned rocket, has its own unique two systems. One is an escape system and the other is a fault detection and processing system. Both systems are designed for manned rockets, and are designed to detect rocket failures during the launch phase and the ascent phase of rocket flight. If there is some catastrophic failure in the rocket, these two systems are used to take astronauts out of the rocket's danger zone in order to ensure the safety of astronauts.

According to reports, this launch is the last manned mission of the Chinese space station in orbit construction phase. In subsequent planning, the Chang-2F rocket will also meet the needs of the space station application and development phase with two missions per year. In the future, rockets will be upgraded, intelligent rockets and reusable rockets are also planned.

CTOnews.com understands that according to the plan, Shenzhou 15 manned spacecraft will adopt autonomous rapid rendezvous and docking mode after orbit, docking at the forward port of Tianhe core module, forming a combination of "three cabins and three ships," which is the largest configuration of China Space Station at present, with a total mass of nearly 100 tons. Shenzhou 15 crew will be in orbit for six months. The main objectives of the mission include verifying the space station's ability to support crew rotation and realizing the first on-orbit rotation of astronauts. Tianzhou-6 and Shenzhou-16 will be welcomed during orbit, and it is planned to return to Dongfeng Six Field in May next year.
