NASA has been streaming on a 24-hour basis from space since September 30, via its ISS HDEV cameras aboard the International Space Station. Watch the earth roll by courtesy of the ISS cameras (2016). The ISS passes into the dark side of the earth for roughly half of each of its 90 minute orbits. As the Space Station passes into a period of night every 45 mins video is unavailable – during this time, and other breaks in transmission is shown. The chat room is open for comments, but as officials say it was attacked on October 13 from hackers.
