Five years after the collapse of the Arecibo Telescope, a radio telescope is back online. The signal is back. 😀 #AreciboWow phl.upr.edu/wow/outreach #RadioAstronomy #Outreach

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.)

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!

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!
