In the waters near Haiyang, Shandong, the Gravity 1 and Y-2 carrier rockets ignited and took off, trailing flames and heading straight towards the sky, sending three satellites into their designated orbits. Commercial aerospace has emerged, injecting new energy into the aerospace industry. The 15th Five Year Plan proposes to accelerate the development of strategic emerging industry clusters such as new energy, new materials, aerospace, and low altitude economy. Currently, global commercial space competition is becoming increasingly fierce. It is predicted that the size of China's commercial aerospace market is expected to exceed 2.5 trillion yuan this year. The synergy between the "tangible hand" and the "intangible hand" will effectively integrate strategic orientation and market vitality, promote rapid technological iteration, continuous cost reduction, and continuous application expansion. China's aerospace industry will emerge with more highlights and vitality. The value of commercial aerospace is primarily reflected in its strategic supplementation and improvement of the national aerospace system. At present, China's "space infrastructure" is steadily advancing. As the LEO satellite Internet enters the stage of large-scale networking, China is faced with the prominent contradiction of "more satellites and fewer arrows". Only relying on traditional rockets, the transport capacity is far from enough. Developing commercial aerospace and providing transportation support for large-scale "space networking" will help ensure that China does not fall behind in future space competition. This year, a batch of new models of commercial rockets such as Zhuque III, Tianlong III, and Gravity II have been designed, tested, and launched as planned. The advent of these new means of delivery will effectively ease the shortage of satellite launch resources and support the construction of the national satellite Internet. Commercial aerospace brings not only an increase in launch opportunities, but also more possibilities for technological routes. Compared to the 'national team', commercial aerospace is more maneuverable and flexible. For example, the liquid oxygen methane engine independently developed by Blue Arrow Aerospace has become a new focus in the global aerospace power field due to its low cost, pollution-free, and reusable characteristics; Star River Power Company has greatly reduced the manufacturing cost of rocket engines through 3D printing technology. With the assistance of market mechanisms, commercial aerospace has gained the favor of many scientific research institutions through the "small steps, fast running, fast iteration" model, making space exploration more "down-to-earth" and forming an effective supplement to the "national team". As a new track for new quality productivity, commercial aerospace has enormous market potential. Beijing is creating a "South Arrow North Star" pattern; Shanghai aims for a scale of industries worth billions of yuan; In Wuxi, Jiangsu, the aerospace industry park has driven the agglomeration and development of more than 120 large-scale enterprises... From a national perspective, more than 10 provinces have issued special policies to support the development of commercial aerospace, cultivating a group of specialized and innovative enterprises in rocket research and satellite development, forming various characteristic industrial clusters, and giving birth to a huge "space economy" ecosystem. From "going it alone" to "working in clusters", a self controlled, resilient and competitive industrial ecosystem is accelerating its formation, becoming a new engine to drive economic growth and promote aerospace technology progress. Nowadays, commercial aerospace not only serves national missions, but also shifts the focus of innovation towards public demand and continues to expand application scenarios. By using satellite remote sensing, farmers only need a mobile phone to remotely control the sprinkler irrigation equipment in the fields; In remote mountainous areas or vast seas, satellite Internet can directly provide broadband services for mobile phones; The intelligent transportation system based on satellite navigation and remote sensing technology can effectively alleviate road congestion by optimizing traffic light timing... These changes indicate that seemingly unattainable space technology is entering ordinary people's homes from the cloud, playing an important role in improving communication, ensuring agriculture, facilitating travel, enriching life, and truly serving people's lives. Looking ahead to the future, commercial aerospace holds infinite potential. This vast sea of stars is not only an exploration of unknown scientific territories, but also an economic blue ocean that nurtures the future. It is waiting for us to explore, discover, and create with innovation and practical work. (New Society)
