In a Hollywood come to life type situation, the plot of Armageddon mainly….The Double Asteroid Redirection Test (DART) will be a practical test of our ability to change the trajectory of an asteroid.
It involves sending a pair of satellites out to a pair of asteroids known as the Didymos binary.
One satellite will crash into an asteroid at nearly 15,000 miles per hour to change its speed by a fraction of a percent, enough to affect its orbit measurably.
The other satellite will attempt to fly by and capture the moment of impact.
DART is scheduled to launch on November 23 aboard a SpaceX Falcon 9.
