MESSENGER has been orbiting the innermost planet for more than three-and-half-years. Principal Investigator Sean Solomon returns with a status report as the mission enters its final phase.
Ilse Cleeves is lead author of a paper that concludes up to half of our solar system’s water is older than the solar system itself. The implications for life across the galaxy are profound.
It’s terribly hard to find exoplanets that look like our homeworld. The search requires development of astoundingly powerful and precise instruments. That’s the job Debra Fischer and her team have taken on.
The Chairman of the powerful Science, Space and Technology Committee in the U.S. House of Representatives joins us for a talk about planetary science, Europa, a human flyby of Mars and much more.
The latest guest of the Red Planet arrived in orbit on the evening of September 22, 2014. Planetary Radio Live was watching with fingers crossed in Pasadena, California.
Inspired by Star Trek, distinguished physicist Miguel Alcubierre developed the general relativity-based model for warp drive 20 years ago. Hear why he doubts it will ever be a reality, and learn about his current research on gravitational waves.
Explore Mars wants to look for life on the Red Planet. Not past life. Life thriving under the Martian surface right now. Chris Carberry will tell us how the ExoLance project might find it.
New Horizons passed through the orbit of Neptune on August 25th. By cosmic coincidence, this was the 25th anniversary of Voyager 2’s flyby of that big, blue world. We catch Principal Investigator Alan Stern right after a celebration in Washington.
Harvard’s Henry Lin led work that determined the soon-to-be-launched James Webb Space Telescope may be able to detect an alien civilization by analyzing its atmosphere.
Venus Express Project Scientist Håkan Svedhem tells us about the spacecraft’s harrowing descent into the Venusian atmosphere, what it is currently up to, and what he’d like to see next at that forbidding planet.
Kepler-186f is the very first exoplanet that is both the size of our own world and in the habitable zone surrounding its star. SETI Institute scientist Elisa Quintana is lead author of the paper announcing its existence.
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.
Astronomers Without Borders Founder and President Mike Simmons and his colleagues share the passion, beauty and joy of the night sky from Argentina to Zambia.
Cassini Project Scientist Linda Spilker joins us at the first Starlight Festival in Big Bear Lake, California, and festival MC Andre Bormanis makes a bonus appearance on the show.
Planetary Radio visited Spacefest in Pasadena to talk with planetary scientist and space artist Dan Durda, Marc Rayman of the Dawn asteroid mission, and a guy who calls himself the Space Cowboy. We also eavesdrop on Apollo 17 Commander Gene Cernan and his lifelong fan, Griffith Observatory Curator Laura Danly.

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.
Join the party as we celebrate the 53rd anniversary of humanity’s transition to spacefaring species with Yuri’s Night Executive Director Loretta Hidalgo Whitesides, Virgin Galactic CEO and Yuri’s Night co-founder George Whitesides, and astronaut Ron Garan, who heads Fragile Oasis.
You may have heard that the sometimes deadly Salmonella bacterium becomes stronger in microgravity. Cheryl Nickerson tell us about this and other results her team has conducted in low Earth orbit.
Emily shares highlights from last week’s Lunar and Planetary Science Conference, and Alan Stern provides updates on the Rosetta comet mission and his New Horizons probe that is nearing Pluto, and addresses the controversy around Uwingu’s Name a Martian Crater project.
