DART Impact mission massively exceeded expectations.

See my post on impact back in September 2020 Bullseye! DART Impacts Dimorphos


Scientists were hoping to nudge the space rock's orbit by just over a minute, but the impact delivered an absolute wallop, shortening its orbital time by a jaw-dropping 33 minutes!

Because Dimorphos turns out to be a loosely packed "rubble pile" asteroid, the crash blasted a massive plume of rocks and dust out into the void, acting like a giant rocket booster that doubled the total punch.

But the chaos didn't stop there - this cosmic collision was so intense it gave the asteroid an entire makeover, reshaping it from a squashed ball into a funky, oblong watermelon (or Triaxial ellipsoid, as NASA like to call it)!

For the first time ever, humanity has actively altered the orbit of a celestial body around the Sun, proving that if a rogue space rock ever threatens Earth, we have the cosmic muscles to flex back. It’s official: planetary defense is no longer just the stuff of Hollywood sci-fi movies, and our planet just became a whole lot safer!

The asteroid Dimorphos was captured by NASA’s DART mission just two seconds before impact.
