任务简介
水星-宇宙神9号是美国水星计划的最后一次载人航天飞行。它搭载了“信仰7号”飞船，宇航员戈登·库珀进入轨道，在再入前完成了22圈轨道飞行。任务持续了34小时19分49秒。这是美国人最后一次单独执行轨道任务。任务出现了多个技术问题，其中最大的问题是，在第21圈轨道时，为250伏主逆变器供电的母线发生短路，导致自动稳定与控制系统停止工作。最终，库珀不得不利用他在窗户上画的线以及手表，正确执行点火，安全再入大气层。

Mercury-Atlas 9 was the final manned spaceflight of the United States' Mercury program. It carried the Faith 7 spacecraft with astronaut Gordon Cooper to orbit where it completed 22 orbits seconds before reentry. The mission lasted for, 34 hours, 19 minutes & 49 seconds. This was the last time an American was launched to space on a solo orbital mission. The mission had several technical problems, the biggest which was a short-circuit in the bus bar serving the 250 volt main inverter causing the automatic stabilization and control system to stop working during the 21st orbit. In the end Cooper had to use lines he had drawn on the window and his wristwatch to correctly execute burns to safely re-enter the atmosphere.
