For every week 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. We also showcase regular features that raise your space IQ while they put a smile on your face.
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.
Sextants have helped sailors find their way across oceans for centuries. Now one is onboard the International Space Station so that astronauts can learn to find their way across the solar system even if other technologies fail.
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.
Freeman Dyson wasn’t the only space star at the ISDC. Mat talks with former astronaut and NOAA Administrator Kathryn Sullivan, leaders of the Cassini mission, innovative students and an expert on dental care in space.
Join Mat Kaplan in California’s Mojave Desert for special coverage of not one but two rocket flights and a real world test of PlanetVac, the innovative, radically simple way to collect surface samples from other worlds.
President Trump just signed a new space policy directive targeting the regulations surrounding commercial spaceflight. Casey Dreier, Jason Callahan, and Mat Kaplan dive into the implications of the new directive and what it means for the relationship between government and space. They also break down all of the good news in the House's new funding bill for NASA, and highlight NASA Administrator Jim Bridenstine's turnaround on climate change.
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.
After announcing it intends to divest from the International Space Station in 2025, NASA quietly released a new report on its transition plans, laying out a series of principles that will set the future of U.S. astronauts in low-Earth orbit. Can a private entity really take over the space station? Where did this idea come from anyway?
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.
Join us for an utterly fascinating live conversation with Emily Lakdawalla about her brand new book, The Design and Engineering of Curiosity: How the Mars Rover Performs Its Job. Also joining us at Caltech were Curiosity Project Scientist Ashwin Vasavada and JPL Research Scientist Abigail Fraeman.
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.
Lori Garver, former Deputy Administrator of NASA, talks with Casey about what the Deputy and Administrator jobs are like day-to-day, how decisions actually get made at the top, and why the current lack of confirmed leadership hurts the space agency.
