Ep. 762: Science in Crisis – NASA’s New Budget
Astronomy Cast Ep. 762: Science in Crisis – NASA’s New Budget By Fraser Cain & Dr. Pamela Gay Streamed live on Jun 30, 2025. Hosted by: Fraser Cain and Dr. Pamela L. Gay Normally we try to end the season on a high note. But there’s unfolding news that we just HAVE to cover before we leave you for the summer. NASA’s new budget is here, and it’s 25% smaller.
