Asteroid Day, June 30th, marks the anniversary of the great Tunguska impact that leveled a Siberian forest. It reminds us that a Near Earth Object can destroy a city or even a civilization. Former Minor Planet Center Director Tim Spahr reviews our efforts to find and understand these bodies.
Veteran Jet Propulsion Lab planetary scientist Bonnie Buratti talks with Mat about the wonder of our solar neighborhood that she explores in
In its nearly five decades, NASA has created or improved thousands of technologies, processes and innovations. Dan Lockney is in charge of making sure these solutions are found and utilized by industries and others in need.
Beautiful Death Valley National Park was the setting for a fascinating conversation with famed SETI researcher Jill Tarter and celebrated astronomer, artist and photographer Tyler Nordgren.
Our special coverage from the Los Angeles Yuri’s Night party continues with Chris Lewicki of Planetary Resources along with Bob Pappalardo and Boback “Mohawk Guy” Ferdowsi who are preparing an orbiter for Jupiter’s ocean world Europa.
Julielynn Wong came directly from her 30-day long HERA IX deep space simulation to our microphone. We talk with her about the experience, and her progress toward 3D medical device printing solutions for astronauts and Earthbound humans.
Come with us on a visit to the home of the prime meridian for a conversation with the curator of the Royal Observatory, Greenwich about the race to create a practical means for determining longitude.
Landing on Mars is hard, and the bigger you are, the harder it gets. Rob Manning returns to tell us about one of NASA’s best hopes for getting much bigger spacecraft down there—spacecraft that may one day carry humans.
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.

What a long, wonderful trip it has been for Spirit and Opportunity, the Mars Exploration Rovers. Planetary Society reporter A.J.S. Rayl has been writing about their adventure every month for ten years. She looks back on this week’s show.
The successful launch of MAVEN was covered by Mat Kaplan, Bruce Betts and Emily Lakdawalla, with special, launch site reports from Jim Bell and Bill Nye.
A burst of laser light could let humanity know it is not alone in the universe. Harvard’s Paul Horowitz and Curtis Mead will give us an update on the technological wonder of Optical SETI that watches the entire sky for billionth of a second pulses from the stars.
Casey Dreier tells the winding tale of Plutonium 238, the radioactive isotope that is vital for exploration of the solar system. The US came dangerously close to exhausting its supply. Even with production restarted, there are major challenges facing explorers.
“Starship Century—Toward the Grandest Horizon” is the new collection of fact and fiction assembled by Gregory and James Benford. The brothers are among the leaders of a renaissance in research and thinking about interstellar travel. They have returned to Planetary Radio to talk about this story of human destiny among the stars.
Only days after Voyager 1 reached interstellar space, forward thinkers met in Houston, Texas to consider how humans can become a starfaring species. Planetary Society Emeritus Executive Director Lou Friedman reports from the meeting.
Planetary Radio returned to the Crawford Family Forum for live coverage of the LADEE launch on September 6th.
Leonard David has been writing about space exploration for more than five decades. Now he has turned his attention to China’s ambitious plans.
