Cloud Formation in the South Indian Ocean

2019年3月，一名国际空间站的宇航员在南印度洋上空265英里处拍摄了这张照片。

空间站就像一个轨道实验室，每90分钟绕地球一周。宇航员们进行有关地球、太空、物理和生物科学的实验，造福了生活在地球上的人们和未来的探险者。作为深空探索的试验台，空间站正在帮助我们学习如何在长时间的太空旅行中保持宇航员的健康，并为人类和机器人在近地轨道之外的探索展示技术。

An astronaut aboard the International Space Station snapped this image of the South Indian Ocean in March 2019, as the station flew 265 miles above this cloudy formation.

The station functions as an orbital laboratory, orbiting the Earth about every 90 minutes. The astronaut crews conduct experiments about Earth, space and the physical and biological sciences, benefitting people living on our home planet and future explorers. As a testbed for deep space exploration, the station is helping us learn how to keep astronauts healthy during long-duration space travel and demonstrating technologies for human and robotic exploration beyond low-Earth orbit.
