This picture of the waning gibbous Moon was taken on Jan 29, 2021, the day after its full Moon phase as the International Space Station orbited 264 miles above China near the Mongolian border. Humanity’s only orbital laboratory, the space station, orbits the Earth about 90 minutes or about 16 times every 24 hours.

这张照片拍摄于2021年1月29日,也就是满月后的第二天,当时国际空间站在靠近蒙古边境的中国上空264英里的轨道上运行。空间站是人类唯一的轨道实验室,它绕地球轨道运行约90分钟,即每24小时运行16次。
