The reporter learned from the China National Space Administration that at 11:11 on December 26, 2021, China successfully launched the Resource No. 1 06 satellite (5-meter optical satellite 02 satellite) with the Long March 4 Cyao 39 carrier rocket at the Taiyuan Satellite Launch Center, which will further promote the systematic application of China's land resources survey and monitoring satellite business.
The 5-meter optical satellite 02 satellite is a business satellite in the National Civil Space Infrastructure Medium- and Long-term Development Plan (2015-2025), operating in a sun-synchronous orbit, with the main payloads of visible near-infrared cameras, hyperspectral cameras and infrared cameras. The satellite launch quality is about 2500 kg, and in orbit can obtain image data better than 5 meters panchromatic, 10 meters multispectral and 30 meters hyperspectral image data, forming a remote sensing observation capability of terrestrial resources with medium spatial resolution, hyperspectral resolution and high temporal resolution. After the satellite is put into use, it will be networked with a 5-meter optical satellite 01 satellite, which will increase the revisit time of the visible near-infrared camera land area from 3 days to 2 days, effectively improve the observation timeliness, achieve efficient global observation, meet the needs of Medium Resolution Remote Sensing Data for China's natural resources monitoring and survey, geological and mineral surveying, geological environment monitoring and other businesses at this stage, and serve disaster reduction, environmental protection, housing, transportation, agriculture, forestry, marine, surveying and mapping and other industries.
At present, the Ministry of Natural Resources has carried out large-scale application demonstrations in the fields of remote sensing survey of geology and mineral resources in the mineralization belt, soil organic matter content in northeast China, water quality monitoring of key inland lake reservoirs and vegetation growth monitoring in major ecological function areas, which has provided new important technical support for key work such as land quality monitoring and evaluation and ecological protection and restoration in China. The infrared camera on the satellite can be used to comprehensive remote sensing monitoring and evaluation of the production capacity of high-energy-consuming enterprises such as steel and coal, and provide data support for national industry supervision.
The launch also carried a small satellite of 101 Middle School Science Popularization, and the user was Beijing 101 Middle School. The satellite is equipped with small imaging cameras, intelligent processing equipment, semiconductor temperature difference power generation experimental equipment and other loads, and will carry out auxiliary geography teaching, science and technology experiments and other secondary school students' science popularization activities after being put into use, as an important part of the China-Africa "Hope" science popularization cooperation plan, it will help build a space exchange platform for Chinese and African middle school students, and explore a new model of China-Africa space cooperation in science education.
The China National Space Administration is responsible for the organization and management of the 5-meter optical satellite 02 satellite project, the China National Space Administration is responsible for the overall work of the project for Earth observation and data center, the Ministry of Natural Resources is responsible for the construction and promotion of the application system as the leading user department, the China Academy of Space Technology and the Shanghai Academy of Aerospace Technology, which belong to the Aerospace Science and Technology Group Co., Ltd., are respectively responsible for the general development of satellite systems and launch vehicle systems, and the satellite launch measurement and control system department is responsible for the implementation of the launch site and the measurement and control system. The Resource Satellite Application Center and the Institute of Aerospace Information Innovation of the Chinese Academy of Sciences are responsible for the construction and operation of the ground system.
The mission was the 403rd launch of the Long March series of carrier rockets.
