The United States has taken some significant steps into the final frontier during its first 250 years.
The nation has put people on the moon, helped build and operate a long-running space station in low Earth orbit (LEO) and sent fleets of robotic explorers to many corners of the solar system — and even beyond it, into interstellar space.
All of this work has been done relatively recently, as the space age didn't dawn until 1957; when the U.S. was born on July 4, 1776, humanity was still seven years away from even balloon-borne flight. Where might we be another 250 years from now, on the nation's 500th birthday, should it be fortunate enough to live that long? Trying to see that far into the future is so difficult as to be a fool's errand, but it's fun. So let's have a brief and far from exhaustive crack.
