Answer by Clayton C. Anderson:
The International Space Station (ISS) flies around the earth in a near circular orbit. The current altitude for that orbit is somewhere around 250 nautical miles. Given that altitude, the period, or time for one orbit is approximately 90 minutes. With a 90 minute orbit and a 24 hour day, the ISS will circle the Earth 16 times a day. That's 16 sunrises and 16 sunsets each orbital day. Makes for some great picture taking opportunities!
Keep lookin' up… you might see ISS somewhere in her 90 minute orbit!
