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, with its high spectral resolution and integrated image-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 disaster monitoring, and astronomical observation, playing an immeasurable role in human societal development, national security, and the national economy.

Recently, Xi'an Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD Technology Co., Ltd. received significant good news! Less than a year after its establishment, the company secured seed round financing from Shaanxi Science and Technology Innovation Aerospace Seed Investment Fund, one of the first seed funds in Shaanxi Province. The Shaanxi Science and Technology Innovation Aerospace Seed Investment Fund was personally selected by the Provincial Party Secretary to serve enterprises within Shaanxi Province, addressing gaps in the province's investment industry chain. It is specifically designed to support early-stage financing for SMEs, focusing on the province's advantageous aerospace industries, deeply investing in the aerospace sector, and targeting the digital economy.

On the morning of November 30, 2021, Peng Xinning, Deputy Director of the Xi'an Municipal Military-Civilian Integration Office, and his delegation visited Xi'an Xi'an Institute of Optics and Precision Mechanics CAS Aerospace Science and Technology Group Co.,LTD Technology Co., Ltd. for guidance. Qin Jing, General Manager of Zhongke Xiguang, received them and reported on their work.
