How NASA Is Defending Earth From Killer Asteroids
by no means: not at all
NASA’s new documentary, Planetary Defenders, shows how scientists are working to protect Earth from asteroids. These rocks could hit Earth at any time, and a 1-kilometer-long asteroid could even end human civilization. Scientists have already found 95% of the largest, most dangerous asteroids, but their job is by no means done. The smaller ones are a challenge to detect.
“Asteroids don’t care about international boundaries,” one scientist explained. This is why countries need to work together to solve this global problem. Another scientist joked, “The dinosaurs went extinct because they didn’t have a space program.” Learn more about NASA’s efforts to keep Earth safe in their upcoming film.
