地球在脚下

Earth’s city lights streak by in this long-exposure photo taken by NASA astronaut Don Pettit on Oct. 24, 2024. The green glow of Earth’s atmosphere is also visible on the horizon.

Since the station became operational in November 2000, crew members have produced hundreds of thousands of images like this one through Crew Earth Observations. Their photographs of Earth record how the planet changes over time due to human activity and natural events, allowing scientists to monitor disasters and direct response on the ground and study phenomena.

在这张NASA宇航员唐·佩蒂特（Don Pettit）于2024年10月24日拍摄的长曝光照片中，地球上的城市灯光闪烁。地平线上还能看到地球大气层的绿光。

自2000年11月空间站投入运行以来，机组人员已经通过对地观测拍摄了数十万张类似的照片。他们拍摄的地球照片记录了地球因人类活动和自然事件而随时间变化的情况，使科学家能够监测灾害并在地面上直接应对并研究现象。
