The impact occurred at 7:15 p.m. ET greeted by cheers from the mission team in Laurel, Maryland. The DART mission, or the Double Asteroid Redirection Test, launched 10 months ago.

Though the days are fast ticking by, that success is far from assured. DART is the first-ever test of what NASA calls a ...

When NASA’s DART spacecraft slammed into the asteroid moon Dimorphos in September 2022, it didn’t just change the asteroid’s orbit as intended—it unleashed a massive barrage of boulders ...

NASA may have created a human-made meteor shower when DART crashed into Dimorphos. They are calling the flying debris Dimorphids.

The DART mission, or NASA's Double Asteroid Redirection Test, will lift off at 10:20 p.m. PT on November 23 aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

So DART took the unusual step of allowing non-NASA-affiliated scientists to participate, which included people from 29 countries, some joining only months before impact.
