In the recent past an explosion equivalent to at least TEN TIMES that of the Hiroshima bomb shattered the quiet over a largely vacant area of the Western Pacific. Was it a hostile Nuclear explosion? An unauthorized test? In fact it was an asteroid...and a relatively small one at that. Scientists now believe it was an asteroid impacting Earth that destroyed the Dinosaurs and just about every other species on the planet. Could it happen again? If we knew one was coming, could we prevent it? There are billions of asteroids spinning through the solar system...thousands with earth-crossing orbits. We will examine what could happen and what we can do about it...not IF...but WHEN the Doomsday Asteroid comes to Earth.
