NASA hits a bullseye: this week, Tom Collina sits down with Dr. Laura Grego, senior scientist at the Union of Concerned Scientists. She discusses NASA’s recent (and successful) DART mission to hit an asteroid in space and the implications for nuclear policy.

On Early Warning, Angela Kellett talks with Istra Fuhrmann and Alex Toma of The Peace and Security Funders Group. They join the podcast to discuss their recent Chronicles of Philanthropy article: Nuclear Weapons Are an Ever-Present Danger — and Grant Makers Need to Pay Attention.
