First hint of Sunrise from Space

A stunning sunrise viewed from the International Space Station, on July 30, 2013, by Expedition 36 Flight Engineer Karen L. Nyberg of NASA.

As the space station orbits the Earth every 90 minutes, traveling at about 17,500 miles per hour, the crew sees about 16 sunrises and sunsets daily.
