DART Mission

DART Mission Latest News

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.

About DART Mission

• 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 on November 24, 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 on 26 September 2022.
  • Weighing in at over 1,000 pounds, the spacecraft’s collision with Dimorphos was as energetic as an explosion of over three tons of TNT. 
  • DART’s collision shortened the orbit of the asteroid by around 33 minutes. 
  • The collision also slightly altered the orbit of the Didymos system around the Sun. 
  • Researchers found that the solar orbital period changed by about 0.15 seconds.
• The mission was a success. For the first time, humans have successfully demonstrated the ability to change the motion of an asteroid in space.
