Our work on understanding the influence of topography on large-scale changes observed on Comet 67P's surface was published in @AAS_PSJ this week, so here's a thread describing why it's exciting. ☄️🛰 @ESA_Rosetta @IamComet67P @CornellAstro

Measuring Erosional and Depositional Patterns Across Comet 67P's Imhotep Region. buff.ly/3IyHgn4 Study finds that local‐scale processes have significant impacts on the overall re‐distribution of material.

Quantifying Morphological Changes and Sediment Transport Pathways on Comet 67P/Churyumov-Gerasimenko doi.org/10.1029/2022JE… Sediment transport appears linked to the location of most direct sunlight on the comet's surface and does not occur on the top of the comet's lobes.

🟢 Final weather check is GREEN 🟢 Let’s go to Jupiter!🚀 Liftoff at 13:14 BST / 14:14 CEST #Ariane5 #VA260 #DestinationJupiter

More reason to be excited about the upcoming VERITAS and EnVision missions to Venus 🤩

We have retrieved signal with @NASA_Orion after an expected loss of signal when the spacecraft flew directly behind the Moon. You can see Earth in the distance. That's us. #Artemis nasa.gov/artemislive

A new study offers the most comprehensive look yet at possible plate tectonic activity on #Jupiter’s ice-covered moon #Europa. Research by Geoff Collins of @wheaton, @moose_juice_13 of @JHUAPL @cornell, @KattenhornSimon of @uaanchorage & others. #AGUPubs eos.org/research-spotl…

Read a summary of our recent work exploring the influence of topography on large-scale changes observed on comet 67P! 🛰☄️

This just in: The #DARTmission impact is confirmed to have changed the orbit of moonlet Dimorphos around its asteroid Didymos. For the first time ever, humans changed the motion of a celestial object. More details: go.nasa.gov/3g2C5kp

🪐We’re always big fans of Saturn, but Neptune’s rings are giving us all the feels in this new @NASAWebb image. It’s the clearest view of the rings of the most distant planet in our solar system in more than 30 years. nasa.gov/feature/goddar…

.@CornellCAS @CornellAstro doctoral candidate Abhinav Jindal is lead author of a paper about how smooth terrains evolve on icy comets. Read the @CornellNews story: news.cornell.edu/stories/2022/0…

Researchers from @CornellAstro have shown how smooth terrains (good for landing exploratory spacecraft!) evolve on #comets – icy bodies made of dust, rocks and gas left over from the solar system’s formation about 4.6 billion years ago. @CSInst as.cornell.edu/news/cornell-s…

With an eye toward a return to Comet 67P, @CornellAstro researchers show how smooth terrain – a good place to land spacecraft and scoop samples – develops on the icy world of a touring comet. @AAS_PSJ @BPFriedlander @CSInst news.cornell.edu/stories/2022/0…

Smooth terrains are not unique to 67P and have been observed on all other comets for which we have resolved surface images. Thus, we can use the tools we have developed here at the Imhotep region of 67P to understand the broader evolution of cometary smooth terrains.

Hence, surface activity is not primarily controlled by surface/subsurface heterogeneities resulting from 67Ps early evolution. Instead, reradiation from topography alone can create local enhancements in activity.
