At 18:30 on September 27, at the Jiuquan Satellite Launch Center, the Long March-2D carrier rocket successfully launched my country's first reusable returnable technology test satellite "Xi Shi 19th Satellite", and the satellite successfully entered the predetermined orbit.As an important new technology test satellite during my country's "14th Five-Year Plan" period, the Shijian-19 satellite has achieved a number of technological breakthroughs in terms of reusability, high microgravity support, high load-bearing ratio, and re-entry environment test services.
It will significantly improve the technical level and application efficiency of my country's returnable satellites, reduce operating costs, and provide strong support for new technology verification and rapid transformation of pre-research results.
Practice satellite 19Space breeding experiments will be carried out, carrying relevant plant seeds selected and sent by Hainan Province, Anhui Province and the Ministry of Agriculture and Rural Affairs., give full play to the advantages of space breeding such as "high mutagenesis efficiency, short breeding cycle, and many beneficial mutations" to improve my country's space breeding technology level, accelerate the pace of germplasm resource innovation, and provide important support for the realization of technological self-reliance in the seed industry and autonomous and controllable seed sources.
Scientific researchers will make full use of the reusable Shixi-19 satellite,Carry out space experiments to provide on-orbit flight test verification opportunities for domestic components and raw materials., promote the development and application of new space technologies, and assist research in microgravity science, space life science and other fields.
In addition, Practice No. 19 satelliteIt also carried payloads applied for by five countries including Thailand and Pakistan., carry out extensive international cooperation.
The Changerding rocket is a normal-temperature liquid two-stage launch vehicle developed by the Eighth Academy of China Aerospace Science and Technology Corporation. It has the ability to launch single and multiple satellites with different orbital requirements from the three major satellite launch centers in Jiuquan, Taiyuan and Xichang. Its 700-kilometer altitude sun-synchronous orbit carrying capacity is 1.3 tons.
Different from previous launches of returnable satellites, this time in order to meet the demand for satellites to carry space experimental equipment, the rocket docked with the satellite and was erected on the tower on standby.It is necessary to wait for the satellite to be installed with the payload about 48 hours before launch before buckling the cover on the fairing tower.
This mission is a Long March series launch vehicle537th timeemission.
