An estimated hundred and fifty million asteroids soaring through our solar system are big enough to level a city. Two million are big enough to destroy a whole continent.  Though scientists have found many of them, we don’t really know where all the dangerous asteroids are or when the next one will strike.

Asteroids bombard our atmosphere all the time. Some are harmless, burning up completely in a flash of light,
or breaking into bits of rock that scatter on the Earth.
But others explode in the sky with a great sonic boom, smashing windows and throwing people to the ground. Worst of all, some asteroids strike our planet head-on, blasting out massive craters and destroying everything nearby on impact.

That’s why a group of dedicated scientists are searching for asteroids in space, studying asteroids that have smashed into the ground, and are making plans to prevent an asteroid strike if a giant space rock is found to be heading our way.Join award-winning nonfiction author Elizabeth Rusch and photographer Karin Andersen in the field for a meteorite hunt, to the edge of an impact crater to survey past damage, into a geology lab to examine space rocks, and to an observatory where telescopes probe the vastness of space, searching for asteroids on a collision course with Earth. It’s a scientific journey that just might save our planet.
