Patrick Michel updates #ACM2026 on the #HeraMission.
Quotes the surface ages for Didymos and Dimorphos as 12.5 million years and <300,000 years respectively.
That was before the #DARTMission impact.

Humans changed an asteroid - now we find out how!
Especially for Asteroid Day, watch the full story so far of our Hera mission, on its way thru deep space to probe the first Solar System body transformed by human action: https://www.esa.int/ESA_Multimedia/Videos/2026/06/Humans_changed_an_asteroid._Now_we_find_out_how

I am working on Greece time for a few days, to call in to the last #HeraMission workshop before the spacecraft arrives at Didymos and sees what the #DARTMission has done: https://www.heramission.space/workshop-2026 .
Thanks go the organizers.

The #HeraMission has released a new promotional poster in advance of the spacecraft's arrival at Didymos this November:

Nur, dass ihr euch schon mal darauf vorbereiten könnt: Ende des Jahres wird die #ESA #heramission das Didymos #Asteroiden|system erreichen. Dann können wir erstmals vor Ort erkunden, was der #DART|Einschlag auf Dimorphos bewirkt hat. Stay tuned #DLR

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

Last week in the Planetary Science Journal:
Ďurech et al. 2025, "A Change of the Rotation Period of Asteroid (65803) Didymos Caused by the DART Impact" - https://iopscience.iop.org/article/10.3847/PSJ/ae29ec/meta .
Reshaping and debris from the impact onto Dimorphos changing the shape of Didymos just a little bit.
Relevant for both the #DARTMission and the #HeraMission .

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.
