Commercial Aerospace: A New Journey Across the Stars and Sea
On August 4, the satellite internet low Earth orbit Group 07, developed in bulk by Galaxy Aerospace, was successfully launched
On August 9, the Geely Constellation 04 satellite group was successfully launched in the offshore waters of Rizhao City, Shandong Province
Entering August, the domestic commercial space sector has been active, with satellite manufacturing, rocket launches, satellite applications, and other sectors of the entire industry chain flourishing across multiple points. Authoritative data shows that by 2025, the size of China’s commercial space market will exceed 2.4 trillion yuan. Looking globally, the rapid advancement of SpaceX’s Starlink program and the fierce competition among low-Earth orbit satellite constellations among countries all demonstrate the vigorous vitality and enormous potential of the commercial space industry. China’s commercial space industry is also developing at an unprecedented pace, becoming a key force driving the construction of a strong aerospace nation.

Environmental reliability testing: the lifeline of commercial aerospace
The tide has arrived, and the starlight lies ahead. The takeoff of China’s commercial aerospace industry relies on solid support at every link in the industry chain.
Currently, China’s commercial space activities mainly rely on two major spacecraft: satellites and rockets. During launch, orbital operation, and return, spacecraft face extremely harsh environments: extreme high and low temperatures, intense vibrations, massive temperature shocks, and ultra-high vacuum. A satellite or a rocket is made up of tens of thousands of precision components and complex systems; any failure in environmental adaptability at any link could lead to mission failure or even catastrophic consequences. Therefore, environmental reliability testing is the “lifeline” running through the entire R&D, production, and validation process of commercial aerospace products, with requirements far exceeding general industrial standards. Core testing items include: high and low temperature shock tests, low pressure tests, comprehensive temperature and humidity vibration tests, and long-term operational stability tests. These tests place nearly stringent demands on the test chamber’s high precision, wide range, rapid temperature variation, strong stability, and low failure rate.

A reliable partner for commercial aerospace environment testing
SCICOOLING, originating from the Institute of Physics and Chemistry, Chinese Academy of Sciences, has been deeply involved in the environmental test equipment field for 20 years. Its reliability test chambers are renowned for their outstanding performance, stability and reliability, and energy savings. They have become reliable partners for many aerospace companies, widely used in satellite and rocket manufacturing, satellite launch services and ground equipment, satellite applications and services, and other segments of the commercial aerospace industry chain. According to incomplete statistics, SCICOOLING has served nearly a hundred companies in the commercial aerospace sector to date, including not only central enterprises such as China Aerospace, China Aerospace Science and Industry Corporation, and China Aviation Corporation, but also private representative companies such as Galaxy Aerospace (satellite manufacturing), Starsky Zhilian (satellite manufacturing), Dongfang Space Technology (rocket manufacturing), Beijing Xinleneng (electrical systems), Beidou Xingtong (satellite navigation), and Huali Chuangtong (satellite applications).
