NASA image: Early morning sunrise over the Grand Canyon

From the International Space Station, NASA astronaut Terry Virts (@AstroTerry) took this photograph of an early morning sunrise over the Grand Canyon and posted it to social media on May 10, 2015.

The space station and its crew orbit Earth from an altitude of 220 miles, traveling at a speed of approximately 17,500 miles per hour.

Because the station completes each trip around the globe in about 92 minutes, the crew experiences 16 sunrises and sunsets each day.
