Among the achievements of the Neil Gehrels Swift Observatory were observations of the DART impact into Dimorphos, making key measurements that helped us interpret the initial vapor plume. 🔭🧪🛰️

Crazy to think it's 4 years since DART proved planetary defense. On Sept 26, 2022, we impacted Dimorphos. That 570kg probe hit at 6.1 km/s, shrinking its orbit by 33 minutes. That's 27x more than they needed. Incredible engineering.
The Night Humanity Moved an Asteroid
Four years ago, on September 26, 2022, NASA's Double Asteroid Redirection Test (DART) mission successfully impacted the asteroid Dimorphos, a moonlet orbiting the larger asteroid Didymos. This histori

Did you know ESA’s Hera mission got its name from the Greek goddess of marriage? 🌌 The team chose it because Hera is exploring a binary (double) asteroid system, Didymos and Dimorphos. The name perfectly captures the cosmic "marriage" binding these two space rocks together!

Upon reflection (heh), I wish I'd explained, in the first tweet in this thread, that the caption the ESA folks gave us is just fine. Everyone understand what it means.
My nitpick was going for the "a display of excessive pedantry can sometimes go so far as to be funny" effect. Not sure I succeeded.

OK you laugh but some of us have been waiting since September 2022 to see Didymos and Dimorphos again and are counting down to November for that opportunity!

Asteroids regularly slam into Earth, but in 2022 a little bit of Earth slammed into an asteroid - in the shape of NASA's DART spacecraft hitting Dimorphos. This autumn ESA's Hera spacecraft reaches this same body to try and find out: could we save Earth from an incoming asteroid? #AsteroidDay

La NASA met à jour et uploade en accès libre toutes les images de la mission DART (y compris les instruments de LiciaCube).
On y retrouve les images de cet incroyable duo d'astéroïdes, Didimos et Dimorphos, quelques instants avant l'impact de déviation. Une danse dans le noir.

When I am not studying asteroids, I write songs about them ;)
Exactly 4 years ago, I released a track to celebrate the success of the DART mission. The song is obviously called "Dimorphos" !

🚨BREAKING SPACE NEWS🚀
Hera, ESA's planetary defense spacecraft heading to the asteroid Dimorphos (the one DART smashed into), flew by Mars yesterday for a gravity assist and to test its cameras.
It took images of Mars and the moon Deimos up close.
AND THEY ARE AMAZING 🤩

Fun fact: evidence from telescopic observations suggests that Dimorphos' entire shape was dramatically changed by the impact. Here's an excerpt from a feature article I wrote for Sky & Telescope about that.
