China advances sea rocket launches

China successfully launched the "Gravity-1 Y3" rocket from a maritime platform in the East China Sea, setting a national record in terms of payload capacity and orbital altitude. The rocket carried nine satellites, including eight for the "Qianfan" constellation and a high-speed communications test satellite, into an orbit approximately 800 kilometers high, with a mass exceeding 3 tons. This achievement follows careful monitoring of the operation from its inception on September 10, amid marine environmental challenges such as heat, humidity, and salt spray affecting the equipment. Maritime launches are considered more flexible and safer, allowing for the deployment of larger satellites and varied inclination angles, with a 100% success rate in 28 maritime launches since 2019.
