Skeptic Check: Project Hail Mary
Science in the latest sci-fi flick

As protagonist Ryland Grace fights to save Earth - and possibly the universe - in Project Hail Mary, author Andy Weir discusses the science behind his sci-fi story and what it’s like to see it adapted for the big screen. From a diversity of aliens thriving in extreme environments, to our sun’s shortening lifespan, to the conundrum of keeping astronauts alive during intergalactic missions, we consider the possibility of science fiction becoming future reality. A NASA astrobiologist who consulted on the book weighs in on how Earthly creatures have inspired some of our favorite science fiction aliens. Plus, science fiction author Becky Chambers discusses how she balances science fact with fiction in her work.

Guests:

Andy Weir – science fiction writer, author of Project Hail Mary, The Martian, and Artemis

Andy Fraknoi – professor of astronomy at the Fromm Institute at the University of San Francisco

Becky Chambers – science fiction writer, author of To Be Taught if Fortunate, the Wayfinders series, and the Monk and Robot novellas

Shawn Domagal-Goldman – NASA acting director, astrophysics division

Skeptic Check: Moon Conspiracy

Skeptic Check: Moon Conspiracy
Why facts can’t eclipse it

Download audio

As NASA’s Artemis program promises to take us back to the moon for the first time in fifty years, we consider what it means that as many as 10% of Americans don’t believe we went there in the first place. Why, despite all the evidence, has the faked moon landing conspiracy persisted? We explore why this falsehood has such staying power and what it reveals about our relationship with science and its findings.  

Meanwhile, lunar science continues unabated. Scientists open a lunar soil sample that’s been vacuumed sealed for a half-century and receive a blast of four and a half billion-year-old solar wind. 

Guests:

Peter Knight – professor of American Studies, English and American Studies and conspiracy expert at the University of Manchester, U.K.

Ryan Zeigler – planetary scientist and NASA’s Lunar Sample Curator at Johnson Space Center

Chasing an Asteroid

Chasing an Asteroid
How space rocks help create - and destroy - environments suitable for life.

Download audio

Everyone knows that a big rock wiped out the dinosaurs. But the danger from an asteroid hitting Earth is not limited to ancient history. To deal with this threat, scientists recently ran an experiment to deflect a potential “city killer.” We’ll hear the results of that experiment, and about a visit to another asteroid. In the dusty material NASA brought back from the asteroid Bennu, scientists found the chemical building blocks of life, including many of the amino acids that are found in our cells. Could an asteroid have brought the ingredients for life to ancient Earth? In this episode, we look at our paradoxical relationship with the space rocks that taketh way – and may help giveth - life.

Guests:

Scott Sandford - Astrophysicist and Research Scientist at NASA’s Ames Research Center

Robin George Andrews - Science journalist, volcanologist, and author of "How to Kill an Asteroid: The Real Science of Planetary Defense"

Birds of a Feather

Birds of a Feather
The story of the world’s first feather detective

Download audio

With only a microscope and a collection of birds, taxidermist Roxie Laybourne became the world’s first forensic ornithologist. The “feather detective” was on the case, examining pieces of plumage to solve mysteries. From bird strikes that caused plane accidents to homicide investigations, no case was too big. In the process, Roxie changed the world of aviation safety and crime investigation forever. Even now, feathers are unraveling a new type of mystery, as scientists from the Bird Genoscape Project use them to map the migratory routes of birds.

Guests:

Chris Sweeney – Journalist and author of “The Feather Detective: Mystery, Mayhem, and the Magnificent Life of Roxie Laybourne

Kristen Ruegg – Co-Director of the Bird Genoscape Project and Associate Professor of Biology at Colorado State University

Celestial Shake-Up
A return to the moon and more

Download audio

We’re going back to the Moon. The planned March 2026 launch of Artemis II is the first crewed mission to the moon since 1972. Historic as it is, it isn’t the only lunar event creating a stir at NASA. Two seismometers are to be delivered to Schrödinger’s Crater in a mission called The Farside Seismic Suite, in which the instruments will measure moonquakes and record the possible impact of asteroid 2024 YR4 on lunar surface. Meanwhile, studies of the sun are heating up. The so-called PUNCH mission, a four-satellite constellation that will create an image of the sun’s corona and solar winds, may help us better understand what drives solar storms and how we can protect Earth from their energetic blasts.

Guests

Eugene Cernan – Apollo 17 astronaut

Harrison "Jack" Schmitt – Geologist and Apollo 17 astronaut

Andrew Rivkin – Planetary astronomer at the Applied Physics Laboratory at Johns Hopkins University

Ceri Nunn – Lunar seismologist and planetary scientist, NASA’s Jet Propulsion Laboratory

Ryan French – solar physicist, at the Laboratory for Atmospheric & Space Physics, Boulder, Colorado, and author of “Space Hazards: Asteroids, Solar Flares and Cosmic Threats

Craig DeForest – Heliophysicist, Southwest Research Institute, principal investigator on NASA’s  PUNCH mission
