The International Space Station takes 92 minutes to travel around Earth, orbiting along the "the terminator line" -- the exact point which separates night from day. Because of the ISS's specific route, the sun appears to never set as the camera rolls.
Weisman has been having fun with social media since leaving the planet, tweeting pictures of toys in zero gravity, shoutouts to family members and selfies from the ISS.

My parents were waving in Maryland at sunrise, so I took a picture of them. pic.twitter.com/kLnaP93Wqz— Reid Wiseman (@astro_reid) June 1, 2014
