The White House's Office of Management and Budget has released a sweeping 400-page proposed rule change that would fundamentally alter how the U.S. federal government manages grants, affecting everything from NASA research to biomedical science and community programs. In this episode, Casey Dreier is joined by Liz Ginexi, a former Program Officer at the U.S. National Institutes of Health, to break down what these changes would mean for American science. Among the most significant proposals: replacing merit-based peer review with partisan political review, allowing grants to be terminated at any time without justification, and restricting scientists' ability to publish their work and attend conferences. Together, Casey and Liz explain how a document dressed up in procedural language could centralize unprecedented control over U.S. scientific funding under a single White House office.

Space Policy Edition: A proposal to stifle American science

Colonel Eileen Collins was the first woman to pilot and command a Space Shuttle, and the person NASA trusted to lead the program back into space after the loss of Columbia. But her story is about so much more than the milestones.

In this episode, Sarah Al-Ahmed sits down with Eileen Collins to discuss “Spacewoman,” a new documentary written and directed by Hannah Berryman, based on Collins' book “Through the Glass Ceiling to the Stars: The Story of the First American Woman to Command a Space Mission.” They talk about what drove her to keep pushing forward, the personal cost of pursuing an extraordinary career, and what it means to break barriers, not just for yourself, but for everyone who comes after you.

Then, Bruce Betts, our Chief Scientist, joins us for What's Up to explore what distinguished pilots and commanders from mission specialists in the space shuttle era, and why that distinction was so critical to Eileen's path to the commander's seat.

Spacewoman with Eileen Collins

The Los Angeles Astronomical Society (LAAS) is one of the oldest and largest amateur astronomy clubs in the United States, and this year, it’s turning 100. To mark the occasion, the LAAS threw a centennial star party on the lawn of Griffith Observatory, featuring 100 telescopes, a dedication ceremony, and a community of passionate skywatchers who showed up rain and all.

In this episode, we sit down with Laura-May Abron, vice president of the Los Angeles Astronomical Society and chair of its Centennial Committee, to discuss what it took to put together the event. We drop into the centennial dedication ceremony to hear from LAAS President Keith Armstrong and Griffith Observatory Director Ed Krupp. We also spend time with some of the remarkable members who make this community what it is, including LAAS historian Louis Chilton, who has been a member for over 60 years, research scientist and LAAS member Bryce Bolin, self-taught optician and telescope builder Jeff Schroeder, and Geo Somoza, volunteer at The Planetary Society and one of the people who has dedicated his life to showing others the sky. Plus, Bruce Betts joins us for What's Up and a look at what you can spot in the night sky in June.
