[img]https://apod.nasa.gov/apod/calendar/S_190602.jpg[/img] A Live View from the International Space Station
Explanation: If you were floating above the Earth right now, this is what you might see. In 2014, a robotic
SpaceX Dragon capsule that delivered supplies to the Earth-orbiting
International Space Station (ISS) also delivered
High Definition Earth Viewing (HDEV) cameras that take and transmit live views of Earth.
Pictured here, when working, is the live video feed that switches between four cameras, each pointed differently. Watch white clouds, tan land, and
blue oceans drift by. The
featured live view will appear black when it is
nighttime on the Earth below, but the space station's
rapid 90-minute orbit compresses this dark time into only 45 minutes. The present location of the ISS above the Earth can be found
on the web. If the video appears gray, this indicates that the view is either being switched between cameras, or communications with the ISS is temporarily unavailable. As the
HDEV project continues, video quality will be monitored to assess the effects of high energy radiation, which types of cameras work best, and which
Earth views are the most popular.
