卫星互联网低轨卫星成功发射！一文看懂我国商业航天“含新量”+“含金量”

Core Viewpoint - China successfully launched a batch of 10 low Earth orbit satellites for satellite internet using the Long March 8A rocket, marking a significant achievement in its commercial space endeavors [1][2]. Group 1: Launch Details - The Long March 8A rocket is a new generation medium-sized liquid launch vehicle designed for the deployment of large satellite constellations in medium and low Earth orbits [2]. - This launch represents the third mission of the Long March 8A rocket in 2023, demonstrating its capability for high-density, multi-task launches [2][5]. - The rocket has a payload capacity of 7 tons to sun-synchronous orbits, showcasing its enhanced capabilities compared to its predecessor [2]. Group 2: Technological Innovations - The Long March 8A rocket has implemented several technological innovations, including full-process automation, active drift control during launch, and supercooled liquid oxygen refueling [6][12]. - The transition from manual to automated operations has reduced risks and eased the operational burden on personnel, enhancing overall safety [8]. - The introduction of active drift control technology allows the rocket to fly away from the launch tower, minimizing collision risks during takeoff [10]. Group 3: Launch Infrastructure - The Long March 8A rocket will primarily operate from a dedicated launch pad at the Hainan commercial space launch site, facilitating high-density launches [13]. - The dedicated launch pad employs an improved "three-vertical" measurement and launch mode, capable of achieving a turnaround time of 7 days between launches [15]. - A practical operation confirmed that the post-launch recovery period can indeed be controlled within 7 days, with a damage rate of less than 5% [15].
