Planetary Radio Episodes
Since 2002, Planetary Radio has visited with a scientist, engineer, project manager, advocate, or writer who provides a unique perspective on the quest for knowledge about our Solar System and beyond. The full show archive is available for free.
Spacecraft OSIRIS REx is now orbiting a 260-meter asteroid named Bennu. Principal investigator Dante Lauretta returns to tell us what has already been learned, and to preview the excitement that is still to come, including the probe’s descent to the surface for collection of a pristine sample.
magine soaring over what may be the solar system’s most Earth-like world, if you ignore the chill. If funded, the nuclear electric-powered Dragonfly will do exactly this. Principal Investigator Elizabeth “Zibi” Turtle shares her enthusiasm.
Join us at the Applied Physics Lab in Maryland for the New Horizons encounter with the most distant object ever visited. You’ll meet mission leaders, friends and even a rock and roll star as we dive deep into this triumph of exploration.
Why do so many spacecraft that are headed across our solar system turn their instruments back to Earth during flybys? OSIRIS-REx was no exception. The answers come from mission scientist Vicky Hamilton
The New Horizons spacecraft will reach faraway Kuiper Belt object 2014 MU69 in the first minutes of 2019. Will the body informally known as Ultima Thule be as mysterious and exciting as Pluto?
This is the 50th anniversary of the most audacious space mission in history. Apollo 8 blazed a path for the first moon landing seven months later, and gave a troubled nation reason for hope and pride.
The InSight lander has only just arrived on Mars. Now, OSIRIS REx has reached asteroid Bennu after traveling through deep space for a year and a half.
Join 1,000 anxious yet thrilled space fans at Caltech for our live InSight landing party. You’ll meet Mat Kaplan’s onstage experts and check in with Bill Nye and Emily Lakdawalla at the Jet Propulsion Lab.
NASA announced on November 19th that the multi-billion dollar 2020 Mars rover will land in Jezero crater, where it will begin the search for the signature of past life.
You haven’t seen the best pictures from the Apollo era and other great space achievements till you’ve seen them in 3D. Queen guitarist and astrophysicist Brian May is also mad about stereoscopic imagery.
The Kepler mission has ended. Listen to highlights of the October 30th media briefing that included the father of the fantastically successful planet finder, William Borucki. Then catch the thoughts of Planetary Society editors and commentators Jason Davis and Emily Lakdawalla.
LightSail 2 is not the only solar sail in the universe. NASA’s Marshall Space Flight Center and the Jet Propulsion Lab are preparing to send NEA Scout on a long, light-propelled journey to a near Earth asteroid.
Happy Astronomy Day, October 13, 2018! We salute humankind’s long history of stargazing by checking in on what will be our planet’s largest telescope. Patrick McCarthy is an astronomer and a leader of the Giant Magellan Telescope project. He returns with a report on the instrument’s status, followed by a fascinating tour of the GMT facility.
A mostly SpaceX episode as the ambitious company provides updated details regarding its huge new rocket and introduces its first astronauts. Mat Kaplan shares more from the company’s headquarters, while Planetary Society Digital Editor explains and explores the BFR.
Elsa Montagnon is Spacecraft Operations Manager for the European/Japanese mission leaving for our solar system’s innermost planet very soon. She joins us to talk about the long journey ahead.
The dust is settling on the Red Planet. Is the remaining Mars Exploration Rover about to rise and shine after three months of slumber? MER Project Manager John Callas returns with a realistic yet hopeful assessment.
We talk with planetary scientist and Lunar and Planetary Institute Director Louise Prockter, who co-led creation of a new report evaluating the performance of NASA's planetary science division.
Mat Kaplan’s Huntsville, Alabama trip wraps up with a tour of the historic and history-making Marshall Space Flight Center. Join him at the control center for research underway on the International Space Station, under a tent where a critical component of the Space Launch System rocket is getting finishing touches, in a conversation about the Fermi spacecraft’s search for the universe’s biggest explosions, and with the Center’s Associate Director for Technical efforts.
Pluto passed in front of a star on the evening of August 14. Mat Kaplan joined pro and amateur astronomers on a mountain to observe this rare event. It may reveal more about the dwarf planet’s tenuous atmosphere and other properties.
We have so much to learn about Venus, says JPL scientist Sue Smrekar. What we learn will help us understand our own world and Mars.
