10次！中国文昌航天发射场年发射量首次达到两位数

Core Points - China successfully launched the Shijian-28 satellite using the Long March 7 modified rocket on November 30, marking the 10th launch from the Wenchang Space Launch Site in 2025, achieving a double-digit annual launch volume for the first time [1][2] - The Wenchang Space Launch Site is China's first self-designed and constructed green, eco-friendly modern launch site, currently equipped with two multi-directional, all-weather, high-capacity launch pads [2] - Since its first launch in 2016, the site has completed 43 missions, steadily increasing its annual launch capacity and establishing a high-density launch capability for medium to large cryogenic liquid rockets [2][3] Technological Innovations - The increase in launch frequency is attributed to the launch team's continuous exploration of new models and optimization of testing processes, significantly reducing the time rockets occupy the launch site [3] - The Long March 7 rocket serves as the dedicated vehicle for the Tianzhou cargo spacecraft, with the testing cycle for the rocket being reduced from approximately 40 days for Tianzhou-1 to around 20 days for Tianzhou-4, with the first implementation of parallel fueling for two types of propellants [2][3] - Recent technological advancements have addressed key challenges such as high-flow fueling of cryogenic propellants and the ability to conduct parallel testing and launches for medium to large cryogenic liquid rockets [3] Future Prospects - The Wenchang Space Launch Site is set to undertake numerous significant national missions in the future, including manned lunar landings, heavy rocket launches, and planetary exploration, with expectations for continued increases in annual launch volume [3]
