UCLA-led study of NASA’s DART mission determines that the strategy presents previously unanticipated risks

Unanticipated? Really? It was the very first thing that crossed my mind when I heard about DART - what happens to all the bits that break off?

Maybe I should give NASA a call... ;-)

Yeah, seems pretty unlikely NASA scientists didn't predict debris from a >13,000km/hr collision of rock and half a ton of metal lol

I have definitely read about fragmentation being a concern in deflecting asteroids a long time ago.

Journalist didn’t think of it.

I remember reading about this idea in the 90s when Armageddon came out.
