In recent years, with policy support and capital investment, China's commercial aerospace industry has experienced significant growth and faces broader development and cooperation opportunities. Against this backdrop, to better ensure the stable development of my country's commercial aerospace industry, on May 30, 2022, Xi'an Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD Technology Co., Ltd. and the Shaanxi Branch of the People's Insurance Company of China (PICC) held a strategic cooperation signing ceremony.

Today, amidst the steady development of the global aerospace industry, China is actively investing in aerospace construction. Against this backdrop, commercial aerospace has experienced rapid growth in recent years, and the market has begun to take shape. Data shows that the size of China's commercial aerospace market is expected to exceed 1.5 trillion yuan in 2022. In terms of market size, China's commercial aerospace industry has entered a period of rapid development; in terms of application scenarios, although commercial aerospace is still in its early stages of development, its room for growth and potential are enormous.

"Peaking carbon emissions and achieving carbon neutrality" refers to the process by which carbon dioxide emissions gradually increase, eventually reaching an inflection point where the annual growth rate reaches zero, and then continuously decline until carbon emissions and carbon removal offset each other, achieving carbon neutrality. The process from "peaking carbon emissions" to "carbon neutrality" represents a shift from relative decoupling to absolute decoupling between economic growth and carbon dioxide emissions. The proposed goals and vision of "peaking carbon emissions and achieving carbon neutrality" elevate China's green development path to a new level, becoming one of the main themes of China's socio-economic development for the next few decades.

With the rapid development of atmospheric sounding and modeling technologies, tracing carbon emissions through atmospheric carbon dioxide concentration observation is considered an effective method for assessing greenhouse gas emission reduction achievements. On December 22, 2016, my country launched its first carbon dioxide observation scientific experimental satellite, TanSat, becoming the third country in the world to provide carbon satellite data.

On October 25, 2021, the World Meteorological Organization (WMO) released its 2021 Greenhouse Gas Bulletin. According to the Bulletin, the global average concentration of CO2 reached 413.2 ppm in 2020, 149% of pre-industrial levels. The annual growth rate of CO2 concentration in 2019-2020 was higher than the average level from 2011-2020.

At 09:56 Beijing time on April 16, 2022, the Shenzhou-13 manned spacecraft's return capsule successfully landed at the Dongfeng Landing Site. Astronauts Zhai Zhigang, Wang Yaping, and Ye Guangfu safely exited the capsule in good health, marking a complete success for the Shenzhou-13 manned spaceflight mission.

"Exploring the vast universe, developing the space industry, and building a space power are our unremitting space dream." — Standing at the strategic juncture of achieving the "two centenary goals," General Secretary Xi Jinping personally outlined the grand blueprint for the leapfrog development of China's space industry, embarking on the great journey of building a space power.

With the continuous development and innovation of hyperspectral technology, significant progress has been made in data acquisition, radiometric calibration, spectral reconstruction, data processing, and ground feature identification. It holds immense commercial market value in areas such as geological mapping, solid mineral and oil and gas surveys, atmospheric sounding, plant growth monitoring and agricultural yield estimation, environmental monitoring, and seawater organic matter detection. It can serve not only industries such as natural resources, agriculture, and environmental protection, but also governments, providing more objective, rapid, and accurate data support for national governance and precise policy implementation. Hyperspectral technology is a new driving force for the development of my country's commercial aerospace industry and occupies a pivotal position in this field.

In the previous issue, we reviewed the rapid development of hyperspectral remote sensing technology in my country's aerospace field in recent years. Since the 1980s, the development of hyperspectral remote sensing technology has brought about revolutionary changes in the scope, scale, content, and research methods of human geoscientific research. Its integration with Geographic Information Systems (GIS) and Global Positioning Systems (GPS) technologies has provided people with a continuous stream of high-precision positioning, high-frequency, multi-spectral macroscopic images at different levels, greatly expanding human vision and visual capabilities, and revealing the interconnections and interactions of various spheres of the Earth at different levels.

In recent years, with the exploration, development, and utilization of Earth's resources, human living environment, and outer space, scientists have increasingly emphasized the research and development of high-tech detection technologies and instruments with high spatial and spectral resolution when using satellites to detect and monitor the land surface, atmosphere, ocean, and space targets. Among these, hyperspectral remote sensing technology, characterized by high spectral resolution and integrated image and spectrum mapping, represents a revolutionary leap in the history of remote sensing technology. Today, hyperspectral remote sensing technology is widely used in many fields such as environmental monitoring, atmospheric detection, Earth resource surveys, natural disasters, and astronomical observation, playing an immeasurable role in human societal development, national security, and the national economy.
