APOD 4.6: Space Station over Lunar Terminator

Positioned to the side of the moon is the International Space Station. This picture was taken in front of a partially lit moon last year in Madrid, Spain, with and exposure time of only 1/1000 of a second. The duration of the transit of the ISS across the entire Moon was about half a second. The station is located on the dark side of the day/night line of the Moon called the terminator.
