Are we learning how to keep men and women alive on a 3-year round trip to Mars?
After a special message we present highlights of the successful arrival at the International Space Station of the Crew Dragon spacecraft, followed by a visit to chilly Mars with planetary scientist Edgard Rivera-Valentin.
Philosopher James Schwartz shares his thoughts about the ethics of space exploration, commercialization, and settlement.
Casey and his guest discuss a bill working its way through the US House of Representatives that challenges the Artemis plan adopted by NASA for human exploration of the Moon and Mars.
As NASA struggles to return humans to the Moon by 2024, it's worth asking: why did it stop in the first place? Space historian John Logsdon joins the show to discuss the politics behind the decision to abandon the Moon in 1972. Casey and Mat also discuss the proposal to offer a $2 billion prize for sending humans back to the Moon and establishing a base there, and why that's not good public policy.
Rick Davis is the perfect person to co-lead NASA’s Mars Human Landing Sites Study. No one is more devoted to putting human bootprints on the Red Planet.

The Planetary Society’s solar sailing cubesat continues to raise its orbit.
Host Mat Kaplan in a long and fascinating conversation with Nicholas de Monchaux, author of Spacesuit: Fashioning Apollo. This great book is about much more than creation of the suits that allowed humans to walk and work on the Moon. Jason Davis shares pointers on looking for LightSail 2 overhead, while Bruce Betts provides a solar sail update in this week’s What’s Up. And you might win a Planetary Radio t-shirt!
Did the public support Project Apollo? Dr. Emily Margolis joins the show to explore the domestic politics and cultural impact of the space age throughout the 1960s. Despite the success of the lunar landings, there was more opposition to Apollo than we generally remember.
Poppy Northcutt was a pioneer—the first woman to work as an engineer in Apollo Mission Control. The program she helped to create got the astronauts back to Earth. Fifty years later, she sits down with Mat Kaplan for a look back.

Mat Kaplan’s Huntsville, Alabama trip wraps up with a tour of the historic and history-making Marshall Space Flight Center. Join him at the control center for research underway on the International Space Station, under a tent where a critical component of the Space Launch System rocket is getting finishing touches, in a conversation about the Fermi spacecraft’s search for the universe’s biggest explosions, and with the Center’s Associate Director for Technical efforts.
The Senate just held a hearing on NASA's efforts to send humans to...Mars? A week later, the same committee advanced legislation to extend the life of the International Space Station to 2030, six years beyond the current end-date and two years beyond the current hardware safety ratings.
