Recently, astronaut Terry Virts looked out the window aboard the International Space Station and saw the moon. He shared this video on Vine of moonset behind Earth’s atmosphere saying it "appears to land on a soft pillow of clouds."
For him and the rest of the station crew, this extraordinary event is a daily occurrence. The space station and its crew orbit Earth from an altitude of about 250 miles, traveling at a speed of approximately 17,500 miles per hour. Since the station orbits Earth every ninety minutes, the crew experiences sunrise, sunset, moonrise, and moonset about sixteen times a day.
