The International Space Station (ISS) is a marvel of current technology and humanity. Sadly, we often forget it's there.
This light sits on a desk and lights up when the space station passes overhead. It stays lit as long as the station is more than 10 degrees above the horizon.
Being reminded that there are astronauts doing science over our heads every day helps reconnect us with our space program.
