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.
Our world was rocked by last week’s announcement of good radar evidence for a liquid water “lake” under the Red Planet’s south pole. Senior Editor Emily Lakdawalla introduces us to the story that is then taken up by two of host Mat Kaplan’s favorite Martians. The Goddard Space Flight Center’s James Garvin headed NASA’s Mars exploration program, while NASA Ames astrobiologist Chris McKay co-founded the Mars Underground more than 35 years ago.
Japan’s Hayabusa2 is just 6 kilometers from asteroid Ryugu as it prepares to snatch samples of the space rock for return to Earth. ISAS/JAXA Director General and former Hayabusa Mission Project Manager Hitoshi Kuninaka joins us for a conversation about the spacecraft and what’s ahead.
President Trump recently ordered the creation of Space Force—but what does that mean? What are the implications for militarization of space? National security expert Dr. Brian Weeden joins the show to explain the announcement.
Ceres is the queen of the asteroid belt. Her first Earthly visitor is nearing its last days in spectacular style. Dawn Mission Director and Chief Engineer Marc Rayman returns with stunning images taken from just 35 kilometers or 22 miles above the dwarf planet, and a preview of the spacecraft’s last days.
The dinosaurs regret their lack of a space program. 200 million years later, humans are gearing up to defend themselves from a species-ending rock.
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.
Planetary geologist Ellen Stofan has just become Director of the most popular museum in the United States. The NASM protects and shares the greatest collection of space and aviation treasures on Earth.
The New Horizons mission was a triumph, revealing Pluto as an utterly unique and beautiful world. But the mission first had to survive challenge after challenge, fighting to be developed, meeting a nearly impossible launch deadline, and then narrowly avoiding disaster when it was barely a week from its destination.
The great adventure awaits! Mat Kaplan hosts an entertaining panel discussion at the 2018 Humans to Mars Summit in Washington DC. Eight guests provide their diverse and inspiring reasons for humans to visit the Red Planet.
After taking over 10 million images of more than 30,000 solar system objects, the NEOWISE mission is finally in its last months. Principal Investigator Amy Mainzer returns with an update on this phenomenal success and a look ahead toward a much more powerful asteroid and comet hunter called NEOCam.
No mission to Mars has done what InSight will do. The lander’s spectacularly sensitive instruments will use the Red Planet’s heat and marsquakes to reveal its deep interior while also revealing secrets of other rocky worlds like our own Earth.
Host Mat Kaplan once again attends the worldwide party for space. Join him at the Los Angeles celebration under Space Shuttle Endeavour.
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.
The multi-award winning science fiction author, futurist and speaker returns to Planetary Radio for a wide-ranging conversation about robots and humans in space, empathetic artificial intelligences, how we can survive the Singularity and much more.
He is known for his breakthrough physics and popularizing of science, but Dr. Hawking also wanted to fly in space. Erik Viirre led the medical team that helped Stephen experience weightlessness.
Seven astronomers have been selected to receive Shoemaker NEO (Near Earth Object) grants from the Planetary Society. They and their observatories span the planet. We’ll meet an American and an Australian. Society Chief Scientist Bruce Betts provides an overview of the grant program and later returns for this week’s edition of What’s Up. The Planetary Society’s Kate Howells reports on the outlook for space funding in Canada’s newly-released federal budget. She and Society CEO Bill Nye also met with Prime Minister Justin Trudeau.
Space is hard. Sample collection and return is harder still. That’s why the radically-simplified PlanetVac system from Honeybee Robotics is so intriguing.
Society members from 21 states descended on the U.S. capitol for a
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.
