SpaceX Falcon 9 Rocket Lifts Off From Launch Complex 39A

SpaceX猎鹰9号火箭从佛罗里达州肯尼迪航天中心39A发射场发射升空，执行Demo-1任务。发射时间为美国东部时间2019年3月2日凌晨2点49分。SpaceX公司的龙飞船机组人员前往国际空间站的旅程旨在验证端到端系统和能力，从而获得载人飞行器的资格认证。美国国家航空和宇宙航行局与SpaceX和波音公司合作开发了商业载人航天器计划，以促进从美国本土发射新的载人航天系统，目标是安全、可靠和具有成本效益地进入低地球轨道目的地，如空间站。

A two-stage SpaceX Falcon 9 rocket lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida for Demo-1, the first uncrewed mission of the agency’s Commercial Crew Program. Liftoff was at 2:49 a.m. EST, March 2, 2019. The SpaceX Crew Dragon’s trip to the International Space Station is designed to validate end-to-end systems and capabilities, leading to certification to fly crew. NASA has worked with SpaceX and Boeing in developing the Commercial Crew Program spacecraft to facilitate new human spaceflight systems launching from U.S. soil with the goal of safe, reliable and cost-effective access to low-Earth orbit destinations, such as the space station.
