Asteroid experts say they’re looking forward to an explosion – but not the kind of extinction-level blast that killed off the dinosaurs 65 million years ago.
Instead, they’re anticipating an explosion of knowledge about near-Earth objects, and how to head them off in case they threaten our planet.
The perils and opportunities posed by the asteroids in our cosmic neighborhood is the focus of Asteroid Day, a global campaign that marks the anniversary of the 1908 Tunguska explosion on June 30.
