"一箭九星"海上發射成功
Sea-based space launch
“一箭九星”海上發射成功China launched a Long March 11 solid-propellant carrier rocket from a ship in the Yellow Sea on Tuesday morning, sending nine satellites into orbit in the nation's second sea-based launch mission.
9月15日上午，我國第二次海上航天發射任務在黃海海域執行，採用固體燃料作爲推進劑的長征十一號運載火箭成功將9顆衛星送入預定軌道。The Long March 11-HY2 blasted off at 9:22 am from the Debo 3, a self-propelled deck barge that was modified for the mission.
9時22分，長征十一號HY2運載火箭從經過改裝的“德渤3號”動力駁船上騰空而起。
About 13 minutes later, after traveling 535 kilometers, it deployed nine Jilin 1 high-resolution Earth-observation satellites in sun-synchronous orbits.
大約13分鐘後，成功將“吉林一號”高分03系列9顆地球觀測衛星送入距離地面535公里的太陽同步軌道。
Each of the satellites, developed by Changguang Satellite Technology in Changchun, Jilin province, weighs about 42 kilograms. They will provide remote-sensing services to users in fields such as agriculture, forestry, land resources and environmental protection.
該型號衛星由吉林省長春市長光衛星技術有限公司研發，每顆重量約42公斤，將爲林業、農業、國土資源、環境保護等行業用戶提供遙感信息服務。The mission helped to optimize seaborne launch procedures and improve the safety and reliability of such operations, laying a foundation for frequent sea-based launches in the future, said Jin Xin, the rocket's deputy project manager.
長十一火箭副總指揮金鑫說，此次發射任務進一步優化了海上發射技術流程，提升了海上發射技術的安全性和可靠性，爲未來實現海上發射常態化、高頻次奠定了基礎。
