When a building isn’t the right size for what we need, we have some choices. We can add onto it, we can knock it down and build a new one, or we can just move to another building.

Riding a rocket must be incredibly exciting. But it must be even better to zoom on a rocket up to the International Space Station and stay there. Sailing 268 feet above our heads, the ISS celebrates its 15th birthday today. So if you look up in the sky tonight and see it floating by, make sure to give it a “Happy birthday” shout out!

There are about 320 million Americans – right now, at least. But how many have we ever had? This isn’t the easiest number to figure out. In 2011 one group did just that, though. And the numbers may shock you!
