description DART Overview

NASA’s DART mission successfully impacted the asteroid Dimorphos in October 2022. This marked the first demonstration of kinetic impactor technology intended for planetary defense. The mission provided valuable data on altering an asteroid's orbit and is crucial for developing strategies to mitigate potential threats from near-Earth objects. Scientists and space agencies utilize this information to refine techniques for deflecting asteroids that could pose a risk to Earth.

help DART FAQ

What was the primary goal of NASA's DART mission?

The Double Asteroid Redirection Test (DART) was designed to test kinetic impactor technology for planetary defense. Its primary goal was to see if a spacecraft could successfully alter an asteroid's orbit by crashing into it.

Did the DART spacecraft successfully hit its target?

Yes, NASA's DART spacecraft successfully impacted the asteroid moonlet Dimorphos on September 26, 2022. This marked the first time humanity deliberately altered the motion of a celestial object in deep space.

How did the DART mission prove that we can deflect an asteroid?

By crashing into Dimorphos, DART successfully shortened the asteroid's orbit around its parent body, Didymos, by approximately 32 minutes. This proved that a kinetic impactor is a viable technique for defending Earth against a potential future asteroid threat.

How big was the DART spacecraft compared to the asteroid?

The DART spacecraft was relatively small, roughly the size of a vending machine and weighing around 1,300 pounds at impact. In contrast, Dimorphos is estimated to be about 525 feet (160 meters) in diameter, making it significantly larger than the probe that hit it.
