So thrilled to have another geologist astronaut!
I'm absolutely THRILLED to hear my Mars colleague, Dr. Lauren Edgar was selected for the 2025 ASCAN Class. She will be an unbelievable addition to the Astronaut Corps- representing our Mars geology community well- and joining our current Mars geology NASA Astronaut, Dr. Jessica Watkins.

Just a reminder that generative AI is theft of labor and intellectual property, uses vast amounts of energy/ water, provides at best mediocre results (if not outright lies or misinformation), actually affects your ability to think over time (mind duh), and is in general a really fucking bad idea.

They’ve indiscriminately fired 10% of NASA employees.
I don’t need to remind you that NASA’s budget is less than 1% of the entire federal budget but I will. Here’s what that looks like, it’s pennies. www.popsci.com/real-cost-na...

I've been looking forward to attending #lpsc2025 for the first time in several years. But, I swear, if there is one more plane crash in the next three weeks, I'm changing my registration to virtual.

It’s been 35 days and my heart is still broken. I will never understand how so many could be so easily duped. I miss the joy. I miss the laughter. I miss the music. I miss the hope. I miss Tim Walz’ dad-isms.

no one’s thinking about that weird thing you said at that party. they’re too busy thinking about how much of Earth’s geologic record has been lost to subduction of the Hadean crust into the mantle.

I can’t stand election post mortems. She was a brilliant candidate. She engaged a lost generation of voters and she almost won. I’m still with her.
