The National Geographic Channel’s “Mars” miniseries has begun. Mat Kaplan attended a kickoff for the ambitious docudrama last summer. You’ll hear from series technical advisor Bobby Braun, author of “The Martian” Andy Weir, Cosmos creator Ann Druyan and more.
The great Cassini spacecraft has a year to go before it plunges into the ringed planet. Project Scientist Linda Spilker returns with more amazing mission science.
The announcement was made just days ago. Co-discoverer Michael Endl tells us about the discovery of a roughly Earth-mass planet orbiting in the habitable zone of the closest star to our own.
The Planetary Society’s solar sail spacecraft was in the middle of a critical test as we spoke with the Society’s Bruce Betts and Jason Davis.
John Grunsfeld closes our coverage of the Space Foundation’s 32nd annual Space Symposium in Colorado Springs. We also meet the leaders of the New Generation Space Leaders Program.
Bruce Betts, Jason Davis, Casey Dreier and Emily Lakdawalla gather with Mat Kaplan for a fascinating and informative Planetary Radio Extra year-in-review roundtable discussion.
MIT planetary scientist and astrophysicist Sara Seager is on a quest. She wants to find a warm, wet exoplanet with signs of life. It could be Earth 2.0.
The National Research Council released its long-awaited report June 4th. Distinguished space policy analyst John Logsdon returns to Planetary Radio with his take on this latest attempt to determine the proper role of humans in space.
Finally found: an Earth-sized planet in the habitable zone. You’ll hear lead scientist Elisa Quintana make the announcement. Then OSIRIS REx mission Principal Investigator Dante Lauretta will tell us how the spacecraft will return a sample of material from the birth of the solar system.
Principal Investigator Fiona Harrison provides an X-ray tour of some of the universe's most fascinating objects, Casey Dreier has analysis of NASA's 2015 budget plans, and Bill Nye sees the inherent optimism of science in the verification of another 715 exoplanets.
SETI Institute researcher and member of the Kepler team Jason Rowe helps us dig into the latest big announcement about hundreds of planets in solar systems like our own.
Take a spacecraft that can no longer survey the realm of galaxies and repurpose it to discover thousands of much nearer asteroids and comets. Put it to sleep for 2.5 years, then wake it up and start discovering even more! JPL’s Amy Mainzer is Principal Investigator for NEOWISE, the mission using this amazing space telescope.
The annual fall meeting of the American Geophysical Union revealed lots of science, some of it astounding. Emily Lakdawalla was there with Advocacy and Outreach Coordinator Casey Dreier, whose news was not quite as good.
Two missions are coming together in a high bay clean room at the Jet Propulsion Laboratory. SMAP and ISS RapidScat went on display for a visit by NASA Administrator Charles Bolden. Mat Kaplan and Emily Lakdawalla provide special coverage.
There will soon be one thousand confirmed exoplanets, but how do we learn more about such distant worlds? We talk to the leader of a team that has recently developed technology capable of revealing the spectra of these planets, which allows us to tease apart their composition. Emily Lakdawalla invites you to find the next “face” on Mars, while Bill Nye says another asteroid flyby is good news. Our special What’s Up space trivia contest prize will put your picture in orbit!
Planetary Radio host Mat Kaplan joined Bill Nye and four passionate planetary explorers on stage at the Planetary Defense Conference in Flagstaff, Arizona.
The 45-meter Near Earth Asteroid flies by on February 15. NASA brought together asteroid experts to discuss it and others of its threatening kind.
Yale Professor of Astronomy Debra Fischer is one of our planet’s most successful discoverers of exoplanets. She has set her sights on Alpha Centauri, where she hopes to find a Earth-sized world in the habitable zone: not too hot, not too cold for life.
The 221st meeting of the American Astronomical Society was a great place to learn about the James Webb Space Telescope from Jason Kalirai and Dean C. Hines.
The 44th Annual Meeting of the AAS Division of Planetary Sciences hosted hundreds of researchers and revealed volumes of scientific results. Join us at the conference.
