Astrophysicist Javier Peralta, a team member on Japan's Akatsuki mission, takes us deep into Venus's thick, fast-moving clouds.
Astrobotic is one of several companies that are building small, robotic landers to take commercial payloads to the surface of the Moon. With a new contract from NASA to support his company’s work, CEO John Thornton looks forward to touching down in 2021. Senior editor Emily Lakdawalla can’t wait for the Europa Clipper to reach Europa, one of Jupiter’s ocean moons. Who doesn’t want more cow bell? Chief scientist Bruce Betts gets his share as he helps us explore the current night sky in What’s Up.
Host Mat Kaplan in a long and fascinating conversation with Nicholas de Monchaux, author of Spacesuit: Fashioning Apollo. This great book is about much more than creation of the suits that allowed humans to walk and work on the Moon. Jason Davis shares pointers on looking for LightSail 2 overhead, while Bruce Betts provides a solar sail update in this week’s What’s Up. And you might win a Planetary Radio t-shirt!
Poppy Northcutt was a pioneer—the first woman to work as an engineer in Apollo Mission Control. The program she helped to create got the astronauts back to Earth. Fifty years later, she sits down with Mat Kaplan for a look back.
Space historian Dr. Roger Launius joins the show to explain why Apollo happened the way it did, how a moonshot briefly became a solution to a national security problem, and why it is unlikely to happen again.
Thirty years ago, Dr. Mark Albrecht led the National Space Council when President George H.W. Bush announced the Space Exploration Initiative, an ambitious effort to send humans to the Moon and then on to Mars.
The Beresheet lunar lander failed in the last few kilometers of its descent to the Moon. Two days later we learned that its team would try again.
Can NASA return astronauts to the Moon by 2024? Vice President Mike Pence shocked the space community by announcing this ambitious new goal just weeks after the Trump Administration proposed a half-billion dollar cut to the space agency.
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.
Planetary Radio Live goes on stage at the first ever Fairplex Extreme STEA2M Festival in Pomona, California. Host Mat Kaplan and Planetary Society CEO Bill Nye are joined by four young space scientists and engineers in front of hundreds of families.
Non-profit SpaceIL’s Beresheet is on its way to the Moon. Only China, the Soviet Union and the United States have safely landed there before. Host Mat Kaplan talks with SpaceIL Senior Systems Engineer Yoav Landsman, while MaryLiz Bender hears from a team member who attended the launch.
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
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.
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.
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.
There’s so much more to Freeman Dyson than the Dyson Sphere. The mathematician, physicist, futurist and author is one of the greatest and most original minds of our era.
We have begun to understand the composition of worlds that are hundreds of trillions of kilometers from Earth. Astronomer Nikole Lewis is co-leader of a team that has used the Hubble Space Telescope to do this with the four Earth-like planets circling a star called TRAPPIST-1.
Mat Kaplan talks with participants in the National Space Society’s recent Space Settlement Summit about human destiny in space.
A computer model based on our best data about Saturn’s cloud-shrouded moon says that torrential liquid methane pounds the surface far more frequently than previously expected. Sean Faulk and Jonathan Mitchell of UCLA explain.
