A graph of total number of submitted abstracts by year for the past six years inclusive.

For those of you what like graphs, here's a plot of total (absolute) numbers of abstracts versus year since 2021 to now. (There was no LPSC in 2020 on account of COVID-19, and I can't be bothered to go back to 2019 or beyond because it's late and I'm tired.)

LPI will not support the community by bending the knee.

I submitted an abstract to LPSC 2026.

I wanted to see how many abstracts were submitted this year. Mine went in at 11:58 pm Central, so is among the last to go in. It will be rejected, but for the student rate ($35) it was worth the experiment.

Planetary friends!

Don't want to go to Houston in March, or support an institute that's bending the knee?

Then join us for the very first Planetary Science Community Workshop in Louisville, KY on April 14–16, 2026.

It's our community. Fight for it!

Life on lava: How microbes colonize new habitats Taking advantage of a "natural laboratory" in Iceland, a research team from the University of Arizona studied how microbes colonize fresh lava flows as soon as they cooled.

🚨 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.

Two intrepid field geologists walking towards a cracked road with two massive lava fountains going off in the distance.

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.

Picture of 7 students standing in front of poster 2294 in the AGU poster hall. The poster title is readable and says Development & Optimization of the Venus Oxygen Fugacity Sensor

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!
