The big loop
It's rare, but it's happened again... I heard a new term and searched for it in Google and found *nothing* related to it's true meaning. The term was "the big loop", which is what NASA calls the open communication channel which is used for communications with the International Space Station (ISS) and the space shuttle. If you listen to NASA TV you hear occasional references to the big loop. NASA has other preferred communication channels with higher bandwidth and privacy, but they have incomplete coverage. The big loop operates 24/7 everywhere all of the time. I was hoping to use Google to find out how we can listen to it, but no luck, so far.
