International Space Station Current Location API

This is a suggestion for your new Intro to Data APIs playlist. This could be a good first video because of how simple the API is. This API returns the GPS location of the ISS in real time. This is useful for tracking because the ISS's boosts itself into a higher orbit every few weeks to fight crashing back to earth. This causes the orbital period to change making future location predictions invalid.
