Didymos et Dimorphos à nouveau?

a few years ago, humanity crashed a spacecraft into an asteroid and CHANGED ITS ORBIT. now we’ve sent another spacecraft millions of miles away to investigate the aftermath.

this is the first close-up image of didymos and dimorphos from esa’s hera mission!!!
Black-and-white spacecraft image of the binary asteroid system Didymos and Dimorphos, captured by ESA’s Hera mission. The larger asteroid, Didymos, appears as an irregular, rocky body illuminated against the darkness of space, while its smaller companion, Dimorphos, is mostly obscured by shadow. NASA’s DART spacecraft deliberately struck Dimorphos in 2022, changing its orbit around Didymos. Hera is studying the asteroid system to investigate the aftermath of that impact.

Die Mission Hera der @esa.int untersucht die Folgen des gezielten Einschlags der NASA-Sonde DART von 2022. Damals verkürzte sich die Umlaufzeit von Dimorphos um Didymos um rund 33 Minuten, stärker als erwartet. Die Erkenntnisse sollen helfen, Asteroiden künftig gezielt ablenken zu können.
Wenige Sekunden vor dem Einschlag der DART-Sonde 2022 (künstlerische Darstellung) 2022 schlug die 610 Ki­lo­gramm schwe­re NA­SA-Raum­son­de DART ge­zielt mit ei­ner hoher Ge­schwin­dig­keit in den Aste­ro­iden Di­mor­phos (links) ein. Ziel der Missi­on war es, die Um­lauf­bahn von Di­mor­phos um sei­nen bi­nären Be­glei­ter Di­dy­mos zu ver­än­dern. Be­rech­nun­gen sa­gen vor­aus, dass sich die ge­gen­wär­tig zwölf­stün­di­ge Um­lauf­zeit um ei­ni­ge Mi­nu­ten ver­än­dern wird. Credit: NASA/Johns Hopkins APL Binäres Asteroidensystem Di­dy­mos und Di­mor­phos sind ein bi­näres As­te­roi­den­sys­tem, das der Er­de 2003 bei sei­nem 25-mo­na­ti­gen Um­lauf um die Son­ne bis auf sechs Mil­lio­nen Ki­lo­me­ter na­he kam. Di­mor­phos, mit ei­ner Grö­ße von knapp 170 Me­tern der klei­ne­re der bei­den Kör­per, wurde 2022 von der NA­SA-Raum­son­de DART gezielt mit fast 22.000 Ki­lo­me­tern in der Stun­de ge­rammt.

Das Fo­to ent­stand zwei Se­kun­den vor dem Im­pakt aus ei­ner Ent­fer­nung von zwölf Ki­lo­me­tern. Der Bild­aus­schnitt ist 31 mal 31 Me­ter groß. Di­mor­phos‘ Nor­den ist oben im Bild.

I'm excited that Hera'll soon give us more pictures of asteroid Dimorphos, DART's target years ago.

The IAU has declared the theme for naming boulders of scientific interest on Dimorphos to be… percussion instruments. Which one plays by whacking them.

We need drum names. It's COVERED in boulders.
Photo of a small asteroid, a "rubble pile" where every discernible bit of the surface appears to be covered with rocks or gravel. Dimorphos orbits a larger asteroid, Didymos, When the DART spacecraft crashed into Dimorphos in 2022, the impact sped up the asteroid's orbital period. Photo: NASA, via Wikimedia Commons.

The European Space Agency's Hera spacecraft is now studying Didymos and its moonlet Dimorphos from 25 - 30 km away.

NASA’s Dart spacecraft deliberately slammed into little Dimorphos in 2022 to see whether such a defensive move might help save Earth from a killer space rock one day.

📸 À 60 km de distance, #Hera révèle une face inédite de Didymos. Le petit éclat en bas, c’est Dimorphos, l’astéroïde dont DART a modifié l’orbite en le percutant en 2022.

📅 Le 25 novembre, l’ESA dévoilera des images détaillées des deux astéroïdes.

Sur fond noir, l’astéroïde Didymos apparaît au centre de l’image, gris et bosselé. En dessous, légèrement à gauche, Dimorphos se distingue par un minuscule croissant lumineux. Le reste du petit astéroïde est dans l’ombre.

On distingue très bien le bourrelet équatorial de Didymos et les rochers à sa surface.

#PPOD: A whole new side of an asteroid comes into view in this remarkable image captured by ESA's Hera spacecraft. Taken from just 60 kilometers away, the image reveals Didymos's rugged surface: a 780-meter-wide asteroid covered in boulders, craters, and intriguing patterns of grooves and ridges. 🧪
The small, irregular, heavily cratered asteroid Didymos is centered against deep black space, with its tiny moonlet Dimorphos visible below it.

For those who have not been following the #HeraMission and the #DARTMission before it:

One of the reasons for the Hera spacecraft to do a detailed survey of the Didymos + Dimorphos binary from tens of kilometers out is to check for any orbiting debris from the DART impact that could damage Hera.

Its smaller companion, the 151-meter-wide Dimorphos, is also in the frame, although most of it is hidden in shadow. This is the side of Didymos opposite the one NASA's DART spacecraft photographed in 2022.

This is so cool: The European Space Agency released images from Hera's framing camera (space dashcam footage!) as the spacecraft closed in on asteroids Didymos and Dimorphos.

Dimorphos is the little one orbiting around. That's the one we smacked in 2022. 🔭🧪
