[Shenjiang No. 1 participated in the construction of the deepest submarine tunnel] On August 23, China's self-developed subsea tunnel shield machine rolled off the assembly line in Changsha, Hunan. The equipment shield machine has an excavation diameter of 13.42 meters, a total length of 130 meters, and a total weight of 3,800 tons. It will participate in the construction of China's deepest submarine tunnel-the Zhujiangkou Tunnel of the Shenzhen-Jiangmen Railway. The Pearl River Mouth Tunnel is a key control project of the Deep River Railway. "Shenjiang No. 1" crosses the section with a total length of 3590 meters. The entire line is tunneled downhill for a long distance and passes through the Pearl River estuary. The engineering geological conditions are extremely complicated. Editor/Xu Shengpeng

• On July 10, 2026, the Long March 10B rocket was launched from the Hainan Commercial Space Launch Site. After the satellite entered orbit, the first stage went through four return stages and was accurately recovered by the Navigator platform using the world's first networked technology, completing China's first controllable rocket recovery. This solution has multiple advantages compared to the overseas landing leg mode, which fills the gap in reusable rocket technology and reduces commercial launch costs. The team plans to conduct a sub level reuse test flight within the year and continuously iterate new and more powerful rockets to help build a complete and repeatable space transportation system.Editor/Gong Ziwei

• [China's first low altitude ocean economy development association established]
• On July 11, 2026, the first provincial-level ocean low altitude integration industry association in China, the Hainan Ocean Low altitude Economic Development Association, was unveiled and established in Haikou. The association will promote the standardized and clustered development of local industries, and sort out 13 major ocean low altitude application scenarios, covering multiple fields and the entire industry chain. The follow-up association will improve industry standards, gather industrial resources, hold industry exchanges, and pilot implementation scenarios. This industry has been included in Hainan's 15th Five Year Plan for Marine Economy. The association will build a bridge for communication between government and enterprises, integrate industrial resources, and help Hainan build a new highland for the development of marine low altitude economy, cultivating a new growth pole for free trade ports.Editor/Gong Ziwei
