In November 2021, NASA’s Double Asteroid Redirection Test (DART) robotic spacecraft took off into space on a SpaceX Falcon 9 rocket from Vandenberg House Drive Base in California, on a mission to intercept and alter the orbit of an asteroid. Now it is lastly time to see the mission in motion.

The $325 million spacecraft has traveled 6.8 million miles (11 million kilometers) from Earth since November and Monday, Sept. 26, it would try its objective of crashing into Dimorphos, a small asteroid that orbits a second, bigger piece of area rock, Didymos, because the pair travels in an elliptical orbit across the sun.

From then on, all the things else is as much as DART.

“DART is a take a look at of the effectiveness of the kinetic impactor technique for altering an asteroid’s orbital path, and of the spacecraft know-how used to ship a kinetic impactor to the goal asteroid,” Lindley Johnson, NASA planetary protection officer, explains through e-mail.
