Everybody is writing about the fifteenth birthday of the International Space Station today and I don’t really think I can add to all of it except say Happy Birthday, too! I’d just like to link to a wonderful article on Universe Today about the very first day on the ISS back on December 10, 1998 when the Russian Zarya and US Unity modules were joined together for the first time. And there’s also this video not from NASA, but the Canadian Space Agency, which brilliantly expresses what the Space Station is all about.
