#Asteroid defense mission shifted the orbit of more than its target
The immediate result was that #Dimorphos’ orbital period around #Didymos, its larger parent body, was slashed by 33 minutes.
Altering moonlet’s orbit doesn’t seem like enough to safeguard Earth from civilization-ending impacts. Observational data has come in, it seems we accomplished more than that. #DART actually changed the trajectory of entire Didymos binary system, altering its orbit around the Sun.

We await the #HeraMission arriving at #Didymos and #Dimorphos to see exactly what the #DARTMission did.

Any useful deflection of a larger #asteroid ☄️ would require a far greater shove or need to occur decades ahead of an impending collision 💥 to have a cumulative effect. You’d need 1,000 #DARTs to get the same deflection https://www.astronomy.com/science/how-we-track-near-earth-asteroids/

Difesa planetaria, risultati dell'impatto di Dart. L’impatto di Dart ha creato una grande espulsione di massi che si sono allontanati da Dimorphos a velocità fino a 52 metri al secondo. Grazie alle immagini raccolte in situ da LiciaCube è stato possibile confermare che l’energia cinetica trasferita a Dimorphos dai materiali espulsi a seguito dell’impatto guidato dell’impattatore...

Ziemlich coole Bildersequenz, die von der Esa-Raumsonde Hera zwischen dem 10. und 15.10. aufgenommen wurde. In den Infrarotbildern sind Erde und Mond zu sehen. Beim Mond kann man sehen, wie er in der Zeitspanne vom Halbmond zum Vollmond wird: 🌓 ➡️ 🌕

Hera ist Anfang Oktober gestartet und auf dem Weg zu den Doppelasteroiden Didymos und Dimorphos.

https://youtube.com/live/LKcup8C5zUo

The spacecraft's instruments have been checked out and it has gone through the first trajectory correction maneuver to set up for the #Mars flyby early next year; where it will do some #Deimos science in passing.

2 years to #Didymos and #Dimorphos .

The #HeraMission will measure the heliocentric orbit change to #Didymos due to the #DARTMission kinetic impact onto #Dimorphos .

Now I am wondering if this technically counts as gravity tractor deflection of the larger asteroid using the smaller one.

The #HeraMission did a pre-launch poll on what the spacecraft will find when it gets to #Didymos and #Dimorphos .

A few people responded "no Dimorphos" after the #DARTMission impact.

But Dimorphos was right there afterwards: https://www.nature.com/articles/s41586-023-05805-2 .

I assume those were errant clicks on the form.

Dimorphos mogelijk vervormd door inslag van de DART-missie

Op 22 september 2022 sloeg de DART-missie van de NASA met succes in op Dimorphos, het maantje van de asteroïde Didymos. Nieuwe numerieke simulaties geven aan dat de DART-inslag heeft geleid tot de vervorming van Dimorphos. DART staat voor Double Asteroid Redirection Test.
