The #HeraMission and also the #DARTMission.

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

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 .

More #DARTMission science in advance of the #HeraMission arriving.

The impact hazard session at #EPSCDPS2025 features overviews of the #DARTMission and the #HeraMission: https://meetingorganizer.copernicus.org/EPSC-DPS2025/session/55132 .

And also a reminder of the importance of avoiding causing an impact hazard when addressing the impact hazard.

Wow! 🤩 #PlanetSci #Mars #HeraMission

🛰️🔴 #HeraMission a survolé Mars et Deimos le 12 mars.
Des images quasi inédites de cette face de la petite lune ont été prises par 3 des instruments de la sonde européenne.

🛰️🔴 #HeraMission a survolé hier Mars et a pu photographier la Lune #Deimos (d'un diamètre de 12,4 km) à environ 1 000 km.

#Mars #space #Deimos

🛰️🔴 Le survol de #Mars par #HeraMission a eu lieu au plus près à 12h51 UTC à ~ 5000 km de distance. Elle a survolé la Lune Deimos à 12h07 UTC à ~ 300 km. L'orientation de la sonde a posteriori a permis la transmission des données recueillies à la Terre (2e photo Ian Carnelli)
Les images seront dévoilées jeudi à partir de 11h50 (heure de Paris) sur https://www.youtube.com/live/cHiASEowrio?feature=shared

Spacecraft cannot hide.

The #HeraMission has completed its flyby of Mars and of Deimos.

Images to be released tomorrow; after downlinking.

The Europa Clipper spacecraft has done its Mars flyby en route back here and then out to Jupiter: https://www.nasa.gov/missions/europa-clipper/nasas-europa-clipper-uses-mars-to-go-the-distance/ .

The next spacecraft to pass #Mars will be the #HeraMission next week: https://www.esa.int/Newsroom/Press_Releases/Media_Invitation_ESA_s_Hera_Mission_-_Mars_Flyby_and_Deimos_Encounter .

To save fuel and to do a little Mars moon science in passing.

Today on the #arXiv :

Richardson et al. 2025, "The Dynamical State of the Didymos System Before and After the DART Impact" - https://arxiv.org/abs/2502.14990

Reviewing the results of the #DARTMission impact.

"The largest uncertainty in the momentum transfer enhancement factor of the DART impact remains the mass of Dimorphos, which will be resolved by the #HeraMission ."
