We explore recent solar activity and discoveries from NASA's Parker Solar Probe with Nour Rawafi, the mission's project scientist.
Voyager project manager Suzanne Dodd and Voyager project scientist Linda Spilker discuss reestablishing contact with Voyager 2 and Carver Bierson from Arizona State University tells the tale of how Io went from a water-rich moon into a world with lakes of lava.
Planetary Radio’s creator Mat Kaplan guest hosts for this look back at the Jet Propulsion Lab’s celebration of the 45th anniversary of the Voyager mission.
Cassini Mission Project Scientist Linda Spilker has now taken on the same job for the Voyager Interstellar Mission.
It’s a party for Voyager and the team of scientists, engineers and others who have followed it across our Solar System. Then we’ll visit with Ann Druyan, creative director for the Voyager Golden Record.
Cassini mission project scientist Linda Spilker returns with new science from ocean moon Enceladus and anniversaries to celebrate with the Voyager mission.
A fun conversation with the leader of the Cassini imaging team, and an audio tour of the transit of Mercury with astronomer Jay Pasachoff.
When will we return to Uranus and Neptune? Planetary scientist Amy Simon explains why a mission to the so-called ice giants is a high priority as she tells us about these mysterious, blue worlds.
It has been 40 years since Carl Sagan and others shared the best of humanity with the stars. A new online multimedia project has been created as a 21st century homage to the Golden Record.
It is most space fans’ favorite planetary science mission, and with good reason. We visit with the man who has been in charge of Voyager mission science for more than four decades.
Three NASA leaders talk with host Mat Kaplan about the progress we're making toward leaving footprints on the Red Planet.
Lindley Johnson has just been named NASA's first Planetary Defense Officer. He's joined on this week's PlanRad by astronomer Kelly Fast, the new manager of the Near Earth Object Observation Program.
JPL’s Blaine Baggett and former JPL director Ed Stone talk “The Stuff of Dreams,” a documentary about an era in planetary exploration that was both exhilarating and exasperating. Emily Lakdawalla explains why Curiosity has joined the fraternity of backward driving rovers on Mars, and Bill Nye considers the not-too-distant future when airliners and spaceliners will share the sky.
The passing of Planetary Society co-founder and former JPL Director Bruce Murray has been marked around the world. Planetary Radio takes its turn with this special tribute.
JPL’s Dave Doody doesn’t just fly around the solar system, he teaches others how it's done. We talk about what students learn in his non-technical class, the Basics of Interplanetary Flight.
Voyagers 1 and 2 just reached 35 years of travel in space. What a great reason to celebrate! Join Voyager Project Scientist Ed Stone, Ann Druyan, Emily Lakdawalla and Robert Picardo in this special live edition of our show. Bill Nye reports on a separate celebration in London and on the International Space Station, and Bruce Betts is back in fine form with Mat Kaplan for this week’s What’s Up.
What better place to talk about Earth's oceans and the seas of other worlds?
JPL volcanologist Rosaly Lopes has discovered more volcanos than anyone else, including 71 on Jupiter’s moon Io. She is fascinated by these fiery (and sometimes frigid) features of our dynamic solar system, and shared her love at the recent SETIcon.
