Gravitational scattering of ejecta in the Didymos system cannot explain the evolution of the binary's orbital period
In the first few months following the DART impact on Dimorphos, it appears that the orbital period dropped by ${\sim} 30$ s in addition to the immediate ${\sim}30 $ min drop. This effect has been attr...

Des rochers éjectés par DART auraient donné trois fois plus d’élan à l’astéroïde Dimorphos que l’impact lui-même ?

Une sonde de la NASA a semé des débris imprévus, compliquant la défense face aux astéroïdes. Quelles conséquences ?
En déviant l’orbite d’un astéroïde, la sonde DART a projeté des roches sur des trajectoires inattendues, à évaluer pour les futures missions.

La NASA a déclenché un événement imprévu en frappant l'astéroïde Dimorphos avec sa sonde Dart
La collision entre la sonde Dart et Dimorphos a transformé l’orbite de cette petite lune et provoqué un vaste nuage de débris. Les chercheurs découvrent des conséquences bien plus larges que prévu.

New analysis of NASA’s DART mission shows boulders ejected from Dimorphos formed clustered streams and carried more momentum than expected. The results raise concerns for asteroid deflection planning.

For those who have not read the entire paper:
Tony Farnham and company have tracked boulders in the #DARTMission ejecta, identifying clusters of boulders produced by the spacecraft's impact fragmenting specific blocks on Dimorphos' surface.
Woah.

Occultation data suggests that Dimorphos is considerably less dense than Didymos, or at least was before the #DARTMission impact.
Need more data; for which the #HeraMission is on the way.

Steve Chesley describes the heliocentric orbit change for Didymos from the #DARTMission impact, rather that the orbit change of Dimorphos about Didymos.
~12 microns/second, measured by occultation timing.
Lots of science from chasing shadows.
