DART Mission:
A groundbreaking study has revealed that NASA’s DART Mission not only altered the motion of a small asteroid within its system but also slightly changed the orbit of the entire asteroid pair around the Sun.
- DART (Double Asteroid Redirection Test) was a NASA space probe dedicated to investigating and demonstrating one method of asteroid deflection by changing an asteroid’s motion in space through kinetic impact.
- It was launched in 2021.
- It was the first-ever space mission to demonstrate asteroid deflection by a kinetic impactor.
- It was the world’s first planetary defense technology demonstration.
- It was aimed at finding out whether or not we could redirect the trajectory of a near-Earth object simply by crashing into it.
- The target of DART was a binary asteroid system consisting of a smaller moonlet, Dimorphos, orbiting around a larger asteroid, Didymos.
- Because the two were linked by gravity, the theory went, knocking little Dimorphos off-kilter would affect both objects.
- DART spacecraft successfully collided with Dimorphos in 2022.
- The mission was a success. For the first time, humans have successfully demonstrated the ability to change the motion of an asteroid in space.
