Season 4 of The Expanse is about to begin on Amazon Prime. Host Mat Kaplan visits with the authors of the eight novels (so far) that are the basis of this outstanding hard science fiction series that begins with humankind having become a spacefaring species that spans the solar system. We’ve also got space headlines from The Downlink. Bruce Betts celebrates more recognition for the Planetary Society’s LightSail project in this week’s What’s Up. https://www.planetary.org/multimedia/planetary-radio/show/2019/1211-2019-the-expanse-authors.html

On Friday, April 13, 2029, asteroid Apophis will pass closer to Earth than our geostationary satellites. While NASA, ESA, and JAXA are all sending missions, a team of students at the University of Maryland is building their own spacecraft to join the fleet. TERP RAPTOR is a CubeSat-based mission roughly the size of a microwave that aims to fly past the asteroid and snap images of its surface as it approaches Earth. Four members of the team join Planetary Radio: Adrienne Rudolph, the Student Principal Investigator; Elena Wu, the Lead Project Manager; Tyler Autrey, the Mechanical, Structure, and Materials Lead; and Alexander Williams, the Propulsion Lead. Together, they talk about how a graduate class project turned into a real mission, what they hope to learn about this potentially hazardous asteroid, and why they're not letting anyone tell them it can't be done.

Then, Bruce Betts joins us for What's Up, where we mark the deployment anniversary of The Planetary Society's own CubeSat-based solar sail mission, LightSail 2.

A team of University of Maryland students is building a CubeSat to fly past asteroid Apophis during its historic close approach to Earth in 2029. Four members of the TERP RAPTOR team join us to share how they're turning a classroom project into a real space mission.

Two hot Jupiters presented at the 248th American Astronomical Society meeting push our understanding of exoplanet atmospheres to the extreme. Research Scientist Tiffany Kataria from NASA's Jet Propulsion Laboratory shares new JWST observations of HD80606 b, the "Roasted Planet,”a gas giant on one of the most eccentric orbits ever discovered. Assistant Professor Lisa Dang of the University of Waterloo joins to discuss CoRoT-2 b, a young, inflated hot Jupiter whose hottest point shows up in an unexpected location on the exoplanet, possibly because the planet hasn't fully tidally locked with its star yet. Then Chief Scientist Bruce Betts joins for What's Up to explore atmospheric super-rotation, winds that outrun the worlds they ride on.

Hot Jupiters: The ‘Roasted Planet’ and the wrong-way hotspot

It may be the best book subtitle we’ve encountered in the Planetary Society book club: “Particles, Poetry and the Cosmic Dream Boogie.” Theoretical physicist and black feminist science theorist Chanda Prescod-Weinstein has followed her acclaimed first book, “The Disordered Cosmos,” with this new, equally celebrated, deeply personal romp across the Universe, “The Edge of Space-Time”.  Swinging from quantum mechanics to hip-hop, and from galaxies to Alice in Wonderland, she guides us through the looking glass to what we know and would love to know about the Universe. It all but guaranteed a mind-bending conversation with host Mat Kaplan that begins with Chanda’s concern for the state of scientific research in the United States, and ends among the stars.
