从太空俯瞰上海

While the International Space Station orbited 260 miles above the East China Sea, NASA astronaut Jasmin Moghbeli snapped this photo of Shanghai’s city lights and the Huangpu River flowing through downtown. Shanghai is the most populous city in China with a population of about 24.9 million.

The space station serves as a unique platform for observing Earth with both hands-on and automated equipment. Station crew members have produced hundreds of thousands of images, recording phenomena such as storms in real time, observing natural events such as volcanic eruptions as they happen, and providing input to ground personnel for programming automated Earth-sensing systems. Having a crew on board provides flexibility, a significant advantage over sensors on robotic spacecraft. Astronauts take images using handheld digital cameras, usually through windows in the station’s cupola, for Crew Earth Observations.

当国际空间站在中国东海上空260英里处运行时，NASA宇航员贾思敏·莫格贝利（Jasmin Moghbeli）拍摄了这张上海城市灯光和流经市中心的黄浦江照片。上海是中国人口最多的城市，人口约2,490万。

空间站是一个独特的平台，可以用实际操作和自动化设备观察地球。空间站的机组人员已拍摄了数十万张图像，实时记录风暴等现象，观察火山爆发等自然事件，并为地面人员提供了自动地球传感系统的编程输入。与机器人航天器上的传感器相比，航天器上的机组人员提供了灵活性，这是一个显著的优势。机组人员通常使用手持数码相机拍摄图像，通过空间站圆顶的窗户进行地球观测。
