China’s Long March-8A Deploys New Internet Satellite Batch
长征八号甲成功发射新一批互联网卫星

China launched a Long March-8A rocket from the Hainan commercial spacecraft launch site on Saturday, sending the 14th batch of low-orbit internet satellites into space. The rocket lifted off at 3:53 p.m. and successfully delivered the payloads into their preset orbit. Developed by the China Academy of Launch Vehicle Technology, the 50.5-meter-long rocket weighs 371 tonnes and can carry up to 7 tonnes to a 700-km sun-synchronous orbit. After its maiden flight in February, the Long March-8A has entered a high-density launch phase. This mission is the first in the Long March-8 series to use coal-based rocket kerosene instead of conventional petroleum fuel. The new propellant is cleaner, easier to store, and more cost-effective while maintaining stable performance, supporting future frequent launches. This flight marks the rocket’s fifth mission and the 612th launch of the Long March family.

中国周六在海南商业航天发射场成功发射长征八号甲运载火箭，将第14组低轨互联网卫星送入预定轨道。火箭于下午3时53分升空。由中国运载火箭技术研究院研制的长八甲全长50.5米、重371吨，具备将7吨载荷送入700公里太阳同步轨道的能力。自今年2月首飞后，长八甲已进入高密度发射阶段。本次任务首次在长八系列中使用煤基航天煤油，替代传统石油基燃料，更环保、易储运且成本更低，同时保持稳定可靠的性能，为后续高频发射奠定“绿色动力”基础。本次发射亦是长八甲第5次执行任务，也是长征系列第612次发射。
