President Donald Trump walks onstage to speak to a crowd at NASA’s Kennedy Space Center in Florida, following the launch of NASA’s SpaceX Demo-2 mission on May 30, 2020. The mission was the first crewed launch of the SpaceX Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station as part of the agency’s Commercial Crew Program. This marked the first time American astronauts launched on an American rocket from American soil to low-Earth orbit since the conclusion of the Space Shuttle Program in 2011.

2020年5月30日，在美国佛罗里达州的NASA肯尼迪航天中心，唐纳德·特朗普总统登上讲台，向人群发表讲话。此前，NASA与SpaceX合作执行的Demo-2任务刚刚顺利发射。这项任务是SpaceX载人龙飞船（Crew Dragon）与猎鹰9号火箭首次将宇航员送往国际空间站，也是NASA商业载人航天计划的一部分。
此次发射具有历史意义——自2011年航天飞机计划结束以来，这是美国宇航员首次乘坐美国火箭，从美国本土发射进入近地轨道。
