Planetary defense test deflected an asteroid but unleashed a boulder swarm::A UCLA-led study of NASA’s DART mission determined that the strategy presents previously unanticipated risks.
Wasn’t it boulders like laying around on the asteroid? Held there by microgravity, and thus knocked in all directions at the impact?
I mean debris from the impact, yes, “boulders” laying around, no I didn’t expect that :-)
OK. Then. I guess the summary would be like, the asteroid was more loose than we though, and we had no idea how the boulders got ejected from the surface because our impact.
