Final day of the #Rosetta #DustWorkshop. Very nice social dinner (and drinks) last night, but today is going to be a struggle! I will be presenting my #67P thermal modelling results just before lunch, and then leading a spinoff discussion this afternoon - hopefully I can stay awake! #PlanetSci

How many potholes (aka craters!) are on an asteroid?

Thanks to Dr. Chabot, who talked about a human-created crater!

NASA’s Curiosity Rover Sees Martian ‘Spiderwebs’ Up Close

A hilly landscape that looks like spiderwebs when viewed from orbit holds clues to the history of water on ancient Mars.

If you want a spacecraft that might be able to actually fly by something like #3I/ATLAS.

(Although the most likely destination for Comet Interceptor remains a new-to-us long period solar system comet.)

With Ariel facing delays, @esa.int Comet Interceptor has found a new ride with a commercial Arian 6 launch customer. Comet Interceptor will carry MIRMIS being built by @oxfordphysics.bsky.social

ESA’s Comet Interceptor mission moves up launch

A delay in one European Space Agency mission is creating an opportunity for an earlier, and more capable, launch for another ESA spacecraft.

Enjoying the *very* small bodies in number 3 and 4, and of course you'd expect me to go for the #comet... But actually I love this #PlanetSci image of #asteroid Donaldjohanson with its interesting bilobate shape. Nothing beats seeing a new object up close for the first time!

Another tough #PlanetSci image of the year choice. The Juno #Jupiter pics are beautiful, and of course #Saturn will always be my first (PhD 😃) love, but there's something about this #JWST #Uranus pic... And maybe if it wins there'll finally be an ice giants mission? 😛

Such a difficult choice! The slopes and Deimos at dawn pics are more beautiful, and a moon hovering in front of its planet is always cool, but I love the dynamism of this one! Really looks like #Perseverance is looking over its shoulder at the dust devil chasing it! #Mars #PlanetSci

What do asteroids smell like??

An incredible question from Sabine, age 5! Thrilled to share this one with everyone, especially my fellow asteroid scientists! (Spoiler alert - I was able to find an actual answer!)
