Life nearby? We’ve not yet found any on our favorite planet, Mars. But even if Mars is sterile, could we ever change that by terraforming it? Or seeding it with life from Earth?
The Red Planet is not the only game in town: A new NASA mission to a Jovian moon may give clues to biology on a world where, unlike Mars, liquid water still exists.
Also, the promise of the James Webb Space Telescope and why the solar system’s largest active volcano offers clues to the habitability of other worlds.
Guests:


Kate Craft – Planetary scientist at the Johns Hopkins Applied Physics Laboratory, where she studies icy moons such as Europa.


Julie Rathbun – Senior scientist at the Planetary Science Institute


Courtney Dressing – Professor of Astronomy, University of California, Berkeley


Chris McKay – Research scientist, NASA Ames Research Center

Before you check your social media feeds today. And post. And post again. And get into an argument on Twitter, lose track of time and wonder where the morning went, consider that social media was never a natural way to socialize.
A cultural anthropologist weighs in on the evolutionary reasons humans can’t thrive on social media. And we hear about the signs that social media is on its way out. If that’s the case, what’s next? 
Guests:
Max Fisher – Reporter for The New York Times, author of “The Chaos Machine: The Inside Story of How Social Media Rewired Our Minds and Our World”
Douglas Rushkoff – Professor of media theory and digital economics at City University of New York, and author of “Survival of the Richest: Escape Fantasies of the Tech Billionaires”
Ian Bogost – Professor of Media Studies and computer science at Washington University in St. Louis and a contributing writer at The Atlantic.
Alex Mesoudi – Professor of Cultural Evolution at the University of Exeter, U.K.

Post Social Media*

It’s not just facts that inform our decisions. They’re also guided by how those facts feel. From deciding whether to buckle our seat belts to addressing climate change, how we regard risk is subjective. In this extended conversation with an expert on the psychology of risk, find out about our exaggerated fears, as well as risks we don’t take seriously enough. Meanwhile, while experts warn society about the dangers of self-aware AI – are those warnings being heeded?
Guest: 
David Ropeik – Professor emeritus Harvard University, and expert on the psychology of risk

Skeptic Check: Feeling Risky*

Ever heard of a beauty quark? How about a glueball? Physics is full of weird particles that leave many of us scratching our heads. But these tiny particles make up everything in the quantum world and in us and are the basis of the fundamental scientific theory called The Standard Model. But it doesn’t explain everything. It can’t account for dark matter or dark energy, for example. We find out whether new physics experiments might force us to rewrite the Standard Model. Plus, we discuss a NASA proposal to fly spacecraft close to the sun in search of new physics.
Guests:
Phil Plait – Aka the Bad Astronomer, former astronomer on Hubble, teacher, lecturer and debunker of conspiracy theories. He is also the author of a new book “Under Alien Skies: A Sightseer’s Guide to the Universe.”
Harry Cliff – Particle physicist at the University of Cambridge who works on the LHCb experiment at the largest particle physics laboratory in the world, CERN. He is the author of: “Space Oddities, The Mysterious Anomalies Challenging Our Understanding of the Universe.”
Slava Turyshev – Research scientist at NASA’s Jet Propulsion Laboratory.

Beyond the Standard Model

Has children’s play become too safe? Research suggests that efforts to prioritize safety harms children’s mental and physical development during play and contribute to anxiety. One solution: introduce risk into play. We visit an adventure playground where kids play unsupervised with anything from scraps of metal to hammers and nails. Plus, what are the evolutionary benefits of play? After all, we’re not the only species who like to roughhouse, sled, or chase balls. And, reclaiming play for those who have outgrown recess.
Guests:
David Toomey - Professor of English, University of Massachusetts. Amherst and author of “Kingdom of Play: What Ball-Bouncing Octopuses, Belly-Flopping Monkeys, and Mud-Sliding Elephants Reveal About Life Itself.”
Mariana Brussoni - Developmental psychologist who studies children's outdoor risky play, and professor at the University of British Columbia in the Faculty of Medicine
Yoni Kallai - Interim director, head playworker and co-founder of play:groundNYC
Peter Gray - Psychology researcher at Boston College and author of "Free to Learn: Why Unleashing the Instinct to Play Will Make Our Children Happier, More Self-Reliant, and Better Students for Life"

The Play's the Thing

How frequently do you think about fasteners like screws and bolts? Probably not very often. But some of them a storied history, dating back to Egypt in the 3rd century BC. They aren’t just ancient history. They help hold up our bridges and homes today. Join us as we dissect a handful of engineering inventions that keep our world spinning and intact.
Guests:
Roma Agrawal - structural engineer and author of "Nuts and Bolts: Seven Small Inventions That Changed the World (in a Big Way)"
