DART is a spacecraft manufactured by NASA and has an important and special mission: to destroy an asteroid.
The mission is led by the Johns Hopkins University Applied Physics Laboratory and NASA. DART is intended to increase planetary defenses to prevent asteroids from affecting Earth.
The spacecraft will be the first demonstration of the “kinetic impactor” technology to change the motion and direction of an asteroid in space.
NASA has clarified that the asteroid that will redirect DART is not a threat to Earth. This is a test site to see if intentionally crashing a spacecraft into an asteroid is an effective way to change its course.
If an asteroid is discovered that threatens the earth in the future, then there may be an action plan.
Asteroids Didymos is the goal of the DART demonstration. The primary body is about 780 meters wide and the secondary 160 meters, ie it is the size of asteroids that can pose a significant threat to Earth.
DART will achieve the deflection of the kinetic shock by deliberately colliding with the asteroid’s small body at a speed of about 6.6 kilometers per second, using a built-in camera (called DRACO) and sophisticated software for autonomous navigation.
