Sometime this year Voyager 1, a probe sent from Earth 35 years ago, will cross a threshold no human-fashioned object has reached before. Passing through a sun-driven shock wave at the edge of the solar system, it will reach the icy dominions of interstellar space.

Still, after three and a half decades of hyper-velocity spaceflight, it will take another 700 centuries for the craft to cross the distance to the nearest star.

Short of a scientific miracle of the kind that has never occurred, our future history for millenniums will be played out on Earth and in the “near space” environment of the other seven planets, their moons and the asteroids in between. For all our flights of imagination, we have yet to absorb this reality. Like it or not, we are probably trapped in our solar system for a long, long time.
