The Return of Cosmos and Ann Druyan

After decades of development, the Nancy Grace Roman Space Telescope is preparing to launch. Once in orbit, Roman will conduct the widest surveys of the universe ever attempted, probing the nature of dark energy, discovering thousands of new exoplanets, and capturing images of billions of galaxies. In this episode, we sit down with Julie McEnery, senior project scientist for Roman at NASA's Goddard Space Flight Center, and Jason Rhodes, project scientist for Roman at NASA’s Jet Propulsion Laboratory, to explore what the telescope will reveal and how scientists around the world will be able to access and work with its data. Plus, in What's Up, we look at Roman's coronagraph and what it will take for the Habitable Worlds Observatory to push that technology far enough to image Earth-like worlds around Sun-like stars.

Will we change or terraform Mars to better suit humans? Or are we more likely to change ourselves to better fit the red planet? How far can evolution take us in these new and exotic environments? These and many other fascinating questions are at the heart of Rice University professor Scott Solomon’s great book, “Becoming Martian”. He joins host Mat Kaplan for a far-ranging conversation in this month’s installment of Planetary Radio’s book club edition.

How will living in space change our bodies and minds? That’s the sub-title of Scott Solomon’s great new book, “Becoming Martian”, and it’s the question he takes up this month on the book club edition of Planetary Radio.

Book Club Edition: Becoming Martian by Scott Solomon

A SpaceX Falcon 9 upper stage slammed into the moon on August 5 after spending over a year and a half drifting through the Earth-Moon system. Jared Head, museum facilitator at Columbia Memorial Space Center, producer at TMRO, and co-host of All Space Considered at Griffith Observatory, walks us through how a rocket launched in January 2025 ended up crashing into the lunar surface. Kate Howells, the Planetary Society's public education specialist, shares her experience witnessing Europe's first total solar eclipse in 27 years from a canyon in Spain on her honeymoon. Plus, Jack Kiraly, the Planetary Society's chief of advocacy, gives us an update on the campaign to save NASA science and the proposed changes to OMB's federal grant-making rules. We close with Bruce Betts, our chief scientist, who joins for What's Up, to discuss Point Nemo, the spacecraft graveyard in the South Pacific.
