太平洋上的日出

An orbital sunrise reveals cloud tops above the Pacific Ocean northeast of New Zealand as the International Space Station orbited 260 miles above on Feb. 10, 2023. Astronauts aboard the space station see 16 sunrises and sunsets per day due to their high orbital velocity—17,500 miles per hour. In the more than 20 years that people have been living aboard, the station has circumnavigated Earth tens of thousands of times.

2023年2月10日，国际空间站在新西兰东北部的太平洋上空260英里轨道上运行，轨道上的日出显示出太平洋上空的云顶。由于轨道速度高（每小时17,500英里），空间站上的宇航员每天能看到16次日出和日落。在人们居住在空间站的20多年里，空间站已经环绕地球数万次。
