New paper out 🥳 Using data from #NASA #Lucy mission and a series of numerical simulations, we show that #Selam, the moon of #Dinkinesh, likely formed through a series of at least four low-velocity collisions between similarly sized moonlets. www.nature.com/articles/s41...

Choosing to go to LPSC now that they've doubled down on banning any content about making the field a better place for underrepresented scientists? That would be rewarding this behavior and make the field even more unsafe! Just a thought!

Always happy to repost #DARTMission content, and happy to point to the Astrobites article discussing Tony Farnham's new paper therein!

Today in examples of how obeying in advance gets you nothing. LPI took down all our DEIA related abstracts to avoid pissing off NASA. And NASA just killed LPSC.

I'm amazed at what people do with the publicly available data of Lucy's encounter of asteroid (52246) Donaldjohanson! Here is a 3D model made by Doug Ellison (@dougellison.bsky.social) from the images in the released GIF. Wonderful! 🤩 sketchfab.com/3d-models/as... #PlanetSci #SciComm 🧪

Why is academia so messed up? I just want to do my science without being constantly told how bad and useless my science is :( #justanotherrejection

Sabina Raducan—The DART impact provided an opportunity to calibrate models of asteroid properties and dynamics. They used this to study how asteroid moons, like Selam (the moon of Dinkinesh observed by the Lucy mission), formed. #LPSC2025

Just in! 📸 The first images from yesterday’s #HeraMission flyby of Mars and its moon Deimos. 👇 www.esa.int/Space_Safety...

Basel, Switzerland

Our Hera spacecraft is flying past Mars! Check out this real-time simulation of what Hera is seeing right now, and tune in to the @esa.int YouTube channel tomorrow at 11:50 CET to see us present the real images! www.youtube.com/watch?v=KILq...

🔔 SUCCESS! ✅ ESA's Hera Mission orchestrated a successful Mars flyby, using the red planet’s gravity to swing it towards its destination asteroids, while also testing its instruments. @esa.int will unveil flyby photos and debrief the operation tomorrow 👇https://www.youtube.com/live/cHiASEowrio

The probability that asteroid 2024 YR4 might impact Earth in 2032 has risen to 2.8%. This means that it has surpassed the chance of impact briefly held by the much larger asteroid Apophis back in 2004. @esaoperations.esa.int ☄️🔭

The #DARTMission had key contributions from people of many genders. Since it's an ESA #WomeinInScience post I'll specifically call out (a few of) our European women contributors like @agastro.bsky.social, @raducan.bsky.social, Naomi Murdoch, Julia de Leon, and LICIACube PI Elisabetta Dotto! 🔭 🛰️ 🧪
