Great to see another contact binary asteroid! Was #Torifune formed by a very gentle merger? Have a look here to find out more about the possible contact binary shapes as a function of impact velocity and angle: www.nature.com/articles/s41... #Hayabua2 #ACM2026
Andy Rivkin@asrivkin.bsky.social · last mo.Torifune!! It looks like another Itokawa! As JB says, it’s a great time for asteroid studies, and hopefully we’ll hear a lot more over the course of the #ACM2026 meeting!
📢 ISSI is hiring a Director of Heliophysics or Planetary Science (30%). A part-time leadership role for an internationally recognised scientist > shaping our scientific portfolio in Bern from October 2026. Deadline: 4 May 2026 👉 issibern.ch/job-posting-director-heliophysics-or-planetary-science/
Today at ISSI, we had the pleasure of hosting the CSH+ Lunch Seminar with Prof. Miki Nakajima @mikinakajima.bsky.social (University of Rochester, US) and Dr. Simon Lock (University of Bristol, UK). 🔭 Thank you to our speakers and to everyone who joined us! 💫 @unibe.ch
Are you looking for a postdoc position working on asteroids and comets? Would it help if it's in a beautiful place in southern France? If yes, then consider applying to the following position of my colleague Benoit Carry at the Observatory in Nice: euraxess.ec.europa.eu/jobs/402212 #planetSci
Post-doc on properties of Solar system small bodies
The small bodies of our Solar system (comets and asteroids) are the remnants of the building blocs that accreted to form the planets. The suite of events that occurred during planet formation left pri...

Scientists around ISSI's @raducan.bsky.social reveal that the tiny asteroid moon Selam did not form in one go: it is a “puzzle” assembled from at least four slow-speed moonlets that gently stuck together over time. 🧩🛰️ See more in the Press Release: www.issibern.ch/asteroids-mo...
PRESS RELEASE
Explore the asteroid Dinkinesh’s tiny moon Selam and how it has been formed from multiple low-speed collisions between small moonlets.

🚀 Big year ahead for space science at ISSI! 🌌 Let’s start with introducing our—and your—new ISSI Science Programme Manager, Sabina Raducan! 😊 We asked her a couple of questions so you get to know her better already: www.issibern.ch/introducing-... 🔭

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...
Multiple moonlet mergers as the origin of the Dinkinesh-Selam system - Nature Communications
Space missions imaging small asteroid moons revealed the variety in shapes. Here, the authors show that repeated low-speed collisions can explain the shape of Selam, which is the smaller component in ...

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!
Corey S. Powell@coreyspowell.bsky.social · 9mo ago3 years ago, NASA crashed the DART spacecraft into an asteroid at 22,000 kilometers per hour. The event changed the asteroid's orbit and tilt & sent it tumbling. A nearby cubesat captured these remarkable images of the asteroid immediately after the impact. 🧪🔭 aasnova.org/2025/11/03/s...
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...
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

ESA Technology@technology.esa.int · last yr.This is a sped up simulation of today's Hera spacecraft flyby of Mars and its Deimos moon - closest approach to Deimos at 12:07 GMT & Mars at 12:51 GMT. The spacecraft has to rotate around to send its images back to Earth so we'll see them tomorrow: www.esa.int/Space_Safety...
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! 🔭 🛰️ 🧪
ESA Space Science@science.esa.int · last yr.💫🎉 Behind every successful ESA space mission, there's a woman. Behind the ESA & NASA Solar Orbiter mission, there are more than a hundred of them! Join us in celebrating them today, on international day of women and girls in science! #WomenInScience #WomenInSTEM 🔭🧪 www.esa.int/ESA_Multimed...
