An impactful day

We"ll be the ones to drop the news on you: It"s Asteroid Day! Today you"re invited to explore a realm of science usually encountered only through white-knuckle action flicks: asteroid impact avoidance, or the study of what the heck we do if we spot a big chunk of space junk hurtling right at Earth. That"s right, don"t worry: People somewhere are coming up with plans for this.
