My grandfathers were born before the first flight of the brothers Wright. Both watched Neil Armstrong and Buzz Aldrin walk on the Moon. In my 60 years, humans and our tools have traveled to 9 planets (I side with the planetary scientists; what else could you call Pluto other than a planetary system?), hundreds of moons, Ceres, and landed on a comet. Sedna awaits. Orbital telescopes already identify hundreds of exoplanets — in just two decades of wide-eyed exploration. More discoveries shelter in the dark of the Solar System, out there. Let’s go.
