3 years ago, NASA crashed the DART spacecraft into an asteroid at 22,000 kilometers per hour. The event changed the asteroid's orbit and tilt & sent it tumbling.
A nearby cubesat captured these remarkable images of the asteroid immediately after the impact. 🧪🔭

We need a reimagined LPSC flavored meeting and the locale should be Tucson in March, after the gem show. Plenty of hotel choices along the free tram line that goes to the convention center. Visit Tucson is onboard to support this. If anyone has the bandwidth to invent the meeting we've got the city.
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.

Of course they want to keep SLS, it brings money to their states, especially as it keeps going over budget and gets delayed.

If you burn down a forest, you don't miss out on lumber for just that season. You have to replant all the trees, nurture them, and wait for them to grow.
The science and research budget cuts happening now are wanton, senseless arson. Recovery, if it ever happens, will take generations.
