Users handed payloads from reusable satellite
Print Edition
The scientific payloads for space breeding and other sci-tech experiments carried by China’s first reusable and returnable satellite, Shijian-19, were delivered to Chinese and foreign users yesterday.
At the payloads handover ceremony held by the China National Space Administration in Beijing yesterday, the CNSA and the China Aerospace Science and Technology Corp signed payload delivery certificates with domestic and international users, including those from Thailand and Pakistan.
Bian Zhigang, deputy head of the CNSA, said the Shijian-19 mission fully leverages the advantages of the new generation retrievable space experiment platform, conducting space breeding experiments of about 1,000 species of germplasm resources, providing crucial support for the innovation of germplasm resources in China. The mission has also offered a valuable in-orbit validation opportunity for domestically produced components and raw materials.
According to Meng Lingjie, director of the Earth Observation System and Data Center under the CNSA, the Shijian-19 mission has made a breakthrough in its recovery module. The satellite platform can be reused more than 10 times, significantly reducing manufacturing costs and improving operational efficiency.
The satellite serves as a space testing platform that enables convenient transportation of payloads between Earth and space, offering high-quality experimental services, said Meng, adding that it has wide-ranging applications in space sci-tech experiments such as space breeding as well as space pharmaceutical and material manufacturing.
The satellite carried 500 kilograms of experiment payloads back to Earth, greatly enhancing the capability for payload recovery, Meng noted. It can also provide a high-quality microgravity environment for experiments.
When the satellite was in orbit, seven new technology experiments were carried out, including microgravity hydrogen production, low-frequency magnetic communications, inflatable sealed cabin and wireless power transmission.
According to Liu Luxiang, executive director of the Institute of Crop Sciences under the Chinese Academy of Agricultural Sciences, the Shijian-19 mission carried seeds of about 1,800 plant materials and more than 1,000 species of microorganisms.
