The International Space Station has four live feed video cameras. Every once in a while you'll see a static screen when they switch from one camera to another.
If the top video is black then they're near, or at, the dark side of the earth.
Every now and then you'll see the moon. It'll be a small disk.
You can enlarge it to, effectively make it a live "screen saver".
They're at an altitude of 252 miles (405 km), and traveling at 17,165 mph (27.624 km per hour).
Worth a look.
