#dimorphos — Public Fediverse posts

💁🏻‍♀️ 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.

The #NEO population is roughly 100,000 at the size of about 60 m, and if we go all the way down to a few meters in size, the population of #NEAs ☄️ is over a billion.

#DART smashed into the 160 m, 5.5-million-ton #asteroid #Dimorphos. If you wanted to deflect an asteroid 10 times larger, you’d need 1,000 DARTs to get the same minuscule deflection.

In April 2029, an #asteroid the size of an aircraft carrier 🚢 will be passing much closer than the Moon. https://www.astronomy.com/science/how-we-track-near-earth-asteroids/

#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/

ESA’s Hera targets early arrival at Didymos asteroids
"
"Thanks to the spacecraft’s good performance, and some clever planning by teams on Earth, Hera is on track to arrive at Didymos in November 2026 – a month earlier than originally planned."

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...

The HERA craft is on it's way to investigate the aftermath of NASA's DART asteroid impact mission the other year, using the gravity of Mars to help it along it's way.
It's getting busy out there! 😀

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.

Update on the #HeraMission from Patrick Michel for @setiinstitute :

https://youtube.com/live/LKcup8C5zUo

The spacecraft's instruments have been checked out and it has gone through the first trajectory correction maneuver to set up for the #Mars flyby early next year; where it will do some #Deimos science in passing.

2 years to #Didymos and #Dimorphos .

Welcome to our Live Coverage of the Launch of ESA’s Hera Mission to asteroid Dimorphos to investigate the impact from NASA’s Dart mission. Our live coverage will started today at 16:30 CEST on our website & here #HeraMission #ESA #ESA_Hera #Darmstadt #Dimorphos #Dart #NASA #Space #science

Two years ago, a probe known as #DART hit the bull's-eye for a collision with a mini-asteroid known as #Dimorphos, changing its trajectory in the process. Now a follow-up probe called #Hera has been launched to do a "crash scene investigation" and see what can be learned about diverting any asteroids that might threaten Earth in the future. https://cosmiclog.com/2024/10/07/hera-probe-heads-off-to-investigate-asteroid-smash-up/ #ESA #Asteroid #Space

Heute um 16:52 Uhr wird die #Esa Raumsonde #Hera starten. Ihr Ziel ist der Asteroid #Didymos und sein Mond #Dimorphos. Die #Nasa hatte vor 3 Jahren durch einen Impakt auf Dimorphos seine Umlaufbahn um Didymos um ~32 Minuten vermindert. Hera wird die Auswirkungen dieses Experiments nach ihrer Ankunft bei dem Doppelasteroiden 2026 genauer untersuchen.
