💁🏻♀️ TIL: 🚀💻 The #ESA’s #Hera mission successfully rebooted its #spacecraft 140 million km from #Earth after uploading new flight #software.
Engineers at #OHB in #Bremen spent 18 months testing the upgrade on a replica before sending commands to the real spacecraft. Hera is now bound for #Dimorphos, the #asteroid whose orbit was altered by #NASA’s #DART mission.

#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/

after closest approach: 69 (46.0%)

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.
