We, Earthlings, can now finally fight back.
Millenia ago, a singular asteroid wiped out the dinosaurs, and for decades, scientists have been exploring the possibility of this happening again. If it does happen, what can we do to prevent it? Is there a solid defense we can conduct against an asteroid? And finally, we now can.
NASA has successfully deflected an asteroid called Dimorphos. Double Asteroid Redirection Test (DART) showed the world that the impact was no accident. Instead, the spacecraft smashed into the asteroid at around 14,000 miles per hour.
With this feat, NASA, for the first time in human history, was able to successfully redirect the orbit of an asteroid.
