On the Gobi Desert in May, camel thorns and Populus euphratica are both green. After 31 years of manned space engineering in China, the first manned spacecraft launch mission was launched in May, when the grass grows and the birds fly. On May 30th at 9:31, three astronauts, Jing Haipeng, Zhu Yangzhu, and Gui Haichao, boarded the Shenzhou 16 manned spacecraft and, supported by the Long March 2F carrier rocket, ignited and lifted off from Dongfeng Space City, embarking on a space journey of about 5 months. This is the first manned flight mission since the full completion of the Chinese space station, and the Shenzhou spacecraft has become the norm with "two launches per year". China is taking another big step towards becoming a strong aerospace country. Looking up at the Milky Way Colored Nine Days on the morning of the 30th, in front of the Wentian Pavilion in Dongfeng Aerospace City, a red flag was displayed during the expedition ceremony, and a thousand people sang "Singing of the Motherland" together. Eleven expeditions, astronauts all set sail from here. Dreams never change; Innovation never stops. Today, China already has a complete near-Earth manned space station and a manned space shuttle transportation system. New breakthroughs have been made in aerospace technology such as rocket technology, spacecraft technology, rendezvous and docking technology, and extravehicular spacesuit development technology. The localization of rocket spacecraft components is becoming increasingly high, and the launch site process is becoming shorter and shorter, laying a solid foundation for China's transition from a major aerospace country to a strong aerospace country. The Long March 2F carrier rocket, which undertakes the launch mission of the Shenzhou 16 manned spacecraft, is the only type of manned carrier rocket in service in China, with a success rate of 100%, and is known as the "divine arrow". The pace of rocket optimization and improvement has never stopped. This time, there are another 20 technological changes that continue to improve the reliability of the rocket and enhance the level of product autonomy and controllability. "Liu Feng, deputy chief designer of the Long March 2F carrier rocket, introduced that the development team has also empowered the rocket with digital and information technology, introducing" intelligent "changes for data interpretation, and achieving real-time communication between the front and back of the Long March 2F carrier rocket test data. As the first manned spacecraft in the application and development phase of China's space station, the Shenzhou 16 manned spacecraft has completed over a hundred verification tasks such as component modifications and reliability improvements. When the Shenzhou-15 manned spacecraft was launched, the Shenzhou-16 manned spacecraft was in an emergency rescue standby state. Gao Xu, the overall chief designer of the manned spacecraft system at the Fifth Academy of Aerospace Science and Technology Group, introduced that the spacecraft system has the ability to launch in an emergency for 8.5 days. If the spacecraft carrying out the mission encounters an emergency situation, the standby spacecraft can quickly take over the work. In order to better meet the long-term needs of astronauts in orbit, the Shenzhou 16 manned flight mission has also been optimized and improved in terms of support. The variety of food has increased to over 150, and the food combination has been optimized, with some personalized foods provided according to the individual dietary habits of astronauts. The Shenzhou 16 spacecraft is equipped with a plant cultivation device that can provide a small amount of fresh vegetables and fruits for the flight crew in space. "Huang Weifen, the chief designer of the manned space engineering astronaut system, introduced that in response to the characteristics and requirements of the Shenzhou 16 crew, medical experts have expressed their concern for the aerospace industry
