🚨 SAVE THE DATE 🚨 We're putting together a Planetary Science Community Meeting at the Kentucky Science Center in Louisville, KY on April 14–16 2026. This is a grass-roots meeting for planetary scientists to gather, discuss, and organize to address pressing issues our community faces. (1/2)

Are you at #AGU25 and are interested in learning more about out the similarities and differences of the recent eruptions in Hawai‘i? Stop by the posters of our @uhhilogeology.bsky.social undergrads, Lichen and Raymond, tomorrow morning and my talk tomorrow (Tuesday) at 4:45 PM in room 352.

Hey AGU folks! I’m not at AGU but we’ve got a gaggle of undergrads (they call themselves the vfoxen)presenting the work they did this past summer and fall on VfOx- the oxygen fugacity sensor they are building to send to Venus on DAVINCI. Go check out their poster!

Space artists: don’t forget to submit your work to The Art of Planetary Science exhibition by December 31st! The event is held in Tucson. Anyone can submit—all levels & types of human-made art. I’ll be submitting and attending again. 🐡🔭🧪 More details here: lpl.arizona.edu/art

You: building your #AGU25 schedule 🤝 Me: providing you a GIF-ed list of #AGU25 talks from GT Cryo group members and friends for you to add to your schedule 🧵

First PhD hooding today! Congrats to Dr. Emmy Hughes 🎉🎉🎉 @spacelover20.bsky.social

Early holiday treat 🎁 New paper led by PLANETAS member Emmy Hughes @spacelover20.bsky.social on salt seasonality in hypersaline lakes in Canada showing how cold forming Na sulfates could be climate indicators if found in martian paleolake sediments! ❄️ agupubs.onlinelibrary.wiley.com/doi/10.1029/...

New listings incoming shortly. ICYMI, stuff I listed last week at elakdawalla.etsy.com

Truly, one of the best parts of living in DC is that @npr.org is here and every once in a while they let me come downtown to blabber about how cool the universe is and stuff 🎙️

I’ll also be at AGU in New Orleans later this month and would be happy to meet and chat! #AGU2025

Passionate about structural geology and/or planetary tectonics? I am looking for a motivated PhD. student (MS applicants also welcome) to join my group starting in Fall 2026. Explore my research on the website below, and email me if you’re interested. jupiterhansen.com #planetaryscience

The organisers of the world's biggest planetary science conference are outlawing any DEI-related submissions because their lawyers are afraid they'll lose federal support. They're losing the support of the planetary science community fucking fast. www.science.org/content/arti...

I am BEGGING scientific instrumentation manufacturers to stop sending instruments with software on CD-ROM disks Especially field equipment... NO LAPTOP HAS THAT ANYMORE

New paper drop led by former postdoc Jacob Adler now at ASU. www.nature.com/articles/s43... Pressure, temperature, & composition affect the transport and morphology of sedimentary flows on Mars - in space and time! ☠️ beware of using earth analogs to interpret Hesperian and Amazonian deposits☠️

Next week at the #GSA2025, I'll be presenting my newly developed Python tool, 𝒑𝒚𝑪𝒐𝒓𝒆𝑹𝒆𝒍𝒂𝒕𝒐𝒓. We apply it to quantitatively re-examine the correlatability of Cascadia deep-water turbidites, previously interpreted as synchronous deposits of paleo-earthquakes. Abstract: lnkd.in/gJ_KHH2j

Planetary geology folks, section meetings for GSA are in the spring. Smaller, but cheaper than a half week of LPSC, posters double the size, talks 17 minutes, abstracts 345 words. Come meet some of your local colleagues! (LPSC was my first meeting, I love going - but hate what it has become.)

What did we discuss in the weekly Friday Science Discussion at the office? Lot's of fun stuff. Let's go through some of them. 1/7 #planetaryscience 🧪

🔭☄️

Thinking far in advance of LPSC 2026 but I do think that a wider, organized boycott would be a very interesting and effective strategy! And it could be fun to organize some counter-programming for those of us boycotting. Maybe "present your favorite LPI-removed abstract" 😂

Terra is of the missions that this administration wants to terminate as it eliminates Earth science from NASA. Gosh I dunno, but it kinda seems like maybe we want more of these satellites, not less? 🤔

🚨New Paper Alert!🚨 I've got a new paper out in Science Advances where we show that the 2 byr old Chang'e 5 magma came from shallow depths in the lunar mantle, and that melting was likely driven by top-down heating of the mantle by radioactive decay in a sub-crustal KREEP layer. ⚒️🧪🔭 Check it out:

It was such an unexpected and happy surprise to have an asteroid named after me! My sincerest thanks to those who made it possible

Ohhh babyyy, it’s Juneteenth! Happy Junteenth from Black In Astro! ✊🏽

There's still time to get those submissions in! As long as it's astro related it counts. We've had some great astro events, including eclipses, aurorae, and more. Astrophotography is eligible as well! @amyraehill.bsky.social @stellerarts.com and @startorialist.com are sponsors! #BlackSpaceWeek

Absolutely stunning work of ⚛️ history in @physicstoday.bsky.social about Ben Lee, the Korean American who was the first head of theory at Fermilab. He hired the first Black woman particle theory lab staff in global history, Shirley Ann Jackson. #BlackandSTEM 🧪 pubs.aip.org/physicstoday...

Happy pride month! I worked with some LA-based scientists and engineers, and we have a kickstarter for space pride t-shirts! Consider backing! 🛰️🏳️‍⚧️🚀🏳️‍🌈🪐 www.kickstarter.com/projects/spa...

Hi all, especially ECRs! My Department is hiring a Visiting Assistant Professor of Earth and Environmental Geoscience. We are a small liberal arts college with a small but engaged geo department. Looking to interview and hire immediately. Please apply! ⚒️ careers.geosociety.org/job/visiting...

Warmest congrats to former SAO Astro REU student *Dr* Osase Omoruyi, seen here with her excellent PhD advisor Dr Grant Tremblay celebrating her successful thesis defense today.

Jezero Mons! Could explain where so much of the Jezero crater volcanic deposits come from. www.nature.com/articles/s43...

Planetary geo folks, consider proposing planetary sessions for your regional GSA meeting (and submit abstracts!). Regionals are small but also more affordable, esp. for students. Yeah, regions don’t usually have much planetary b/c spring is LPSC. Let’s change that. Session proposals due July 15.

USRA/LPI has announced that they intend to proceed with "LPSC 2026" next year, despite NASA seemingly no longer planning to support that meeting. But why would the community participate in such a meeting when USRA/LPI has shown such disregard for topics we hold to be important?

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.
