Live HD Feed from the International Space Station. It may take two clicks to get it going. The feed is from alternating views of 4 different cameras (if screen is black, then the Station is on the dark side of the Earth). If you mouse over “Live” in the right bottom corner of the screen you will see a full screen toggle option.
What makes this so much more compelling to watch than an ordinary satellite feed is that you know there are humans up there with these cameras. The International Space Station travels in orbit around Earth at a speed of roughly 17,150 miles per hour (that’s about 5 miles per second!). This means that the Space Station orbits Earth (and sees a sunrise) once every 92 minutes!
