Host Mat Kaplan has wanted to reshare his first conversation with the great Sally Ride for years. Sally talks about women in space, the loss of space shuttle Challenger, and her devotion to sharing the wonders of science with young girls through Sally Ride Science. Planetary Society editor Rae Paoletta takes us to Jupiter’s Great Red Spot. Is it shrinking? We also celebrate the return of the space trivia contest.

A first-ever encore of our wonderful conversation with the first American woman in space.

Sally Ride: Revisiting our 2005 conversation

Between budget battles, proposed grant rule changes, and an exploding Blue Origin rocket, there's a lot to cover in U.S. space policy right now. Jack Kiraly, The Planetary Society's director of government relations, joins host Sarah Al-Ahmed to walk through a cascade of developments affecting NASA and the broader U.S. science community, including a proposed rule change at the Office of Management and Budget that would hand control of federal research grant decisions to political appointees, bypassing the peer review process that has underpinned U.S. science for decades. Kiraly also discusses a major reorganization at NASA, a new competition for the management of the Jet Propulsion Laboratory, the fallout from the New Glenn explosion, and what it means for the future of Artemis.

Plus, in What's Up, the names of the Artemis III crew are revealed.

U.S. space science in flux: Grant rules, rockets, and reorganization

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.
