Some more details on the rationale for the delay of the #ArtemisII launch. Fingers crossed there are easy fixes and that the this will only be a 1 month delay.

I can't imagine how hurtful and insulting Trump's comments about NATO involvement in Afghanistan have been to those who served, and for those who lost loved ones. I can only hope that the outpouring of condemnation today from 🇨🇦🇬🇧🇩🇰🇵🇱🇳🇱 & all the other nations that served is a sign that enough is enough.

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.
drcrater.bsky.social Gordon "Oz" Osinski @drcrater.bsky.social · Nov 18
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.
