Happy Birthday ISS!
We want to wish the International Space Station an official Happy 15th Anniversary. The first piece was launched on November 20, 1998, but it was on Dec. 10, 1998, that the first human residents arrived—Commander Bob Cabana and cosmonaut Sergei Krikalev. So Happy Birthday ISS from all of us at On Science!
