This is the older of the two main ISS video feeds. Although not as high quality as the other feed, this one has more variety. It frequently changes view so over time you'll see many interesting angles. Occasionally you'll see work being done such as spacecraft maneuvering, robotic arm operations, extra-vehicular activities (spacewalks), or internal views of astronauts inside the station. This feed also includes occasional audio such as astronauts communicating with ground control.
