Although I might submit a print only abstract that talks about how diversity, equity, and inclusion is fundamentally important for science & how it drives my research program.
Well, I was on the fence but this makes the decision easy. No LPSC for me.
Abstracts submitted to LPSC 2026 are required to comply with White House (non-legally binding) executive orders forbidding mention of topics related to diversity, equity, and inclusion.
At least USRA/LPI isn't hiding it.
But is this what our community wants? Or deserves? I don't think so.

Thanks so much @cmdr-hadfield.bsky.social for sharing the @westernu.ca news story about our paper on the beneficial effects of meteorite impacts for microbes!
When asteroids slam into Earth they create a warm, wet local environment. These 3 guys dug through 78-million-year-old core samples to show how quickly life moves into the hellscape, to understand Earth history. news.westernu.ca/2025/09/life...

The less glamorous side of #fieldwork - after a promising start, we lost a drone & then the rain started. And the outcrops were, well, less than impressive! We returned soaked to the skin back to camp. But a dry sleeping bag feels like the best thing in the world 😊 #fieldwork #outdoors #camping
