SpaceX首次涉足军事 为国防部发射侦察卫星
This launch has great
symbolic5 significance for SpaceX, since it's the company's first mission for the Pentagon.
由于这是SpaceX为五角大楼执行的首个任务,此次发射对该公司具有重要的象征意义。
For years, the market for launching US military payloads was dominated by the United Launch Alliance, a
joint6 venture of Lockheed Martin and Boeing.
多年来,发射美国军方卫星的市场一直由洛克希德马丁和波音的合资公司美国联合发射联盟主导。
But SpaceX broke the monopoly in 2015, when the US Air Force
certified7 its Falcon 9 rocket to launch national security space missions.
不过2015年,美国空军批准猎鹰9号火箭执行国家安全太空发射任务时,SpaceX打破了这一垄断。
Since then, the California-based company has also won two contracts to launch Global Positioning System satellites for the US Air Force.
自那之后,这家位于加利福尼亚的公司已经拿下了两笔为美国空军发射全球定位系统卫星的合同。
