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.
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.
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.
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.
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.
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.
Mat Kaplan attended a meeting of the science team for the zoom lens camera that will be atop the Mars 2020 rover mast. Planetary Scientist Jim Bell tells us how this new system will show us the Red Planet as we’ve never seen it before.
It may not host an alien “megastructure” but Tabby’s Star still guards many mysteries of science. Astronomer and astrophysicist Tabetha “Tabby” Boyajian leads the worldwide team that is revealing this strange light in the sky.
Mat’s first-ever four-way conversation with Jason Davis, Casey Dreier and Emily Lakdawalla reviews the biggest 2017 events in space exploration and provides their predictions of what to look for in the new year.
Dawn Mission Director and Chief Engineer Marc Rayman helps us salute the ion-engine powered spacecraft that first orbited asteroid Vesta in the main asteroid belt and then moved to dwarf planet Ceres, revealing two fascinating worlds.
It’s the Grandest Finale. The spectacular Cassini mission’s exploration of Saturn will end on September 15th when the spacecraft plunges into the planet. Cassini Project Scientist Linda Spilker is back with one last mission update.
The Cassini Mission has less than two months to go before it ends with a spectacular plunge into the beautiful ringed world. Planetary Society Senior Editor Emily Lakdawalla has prepared a guide to the last orbits by the historic spacecraft.
Have you seen its stunning image of Jupiter’s south pole? The Juno orbiter is surpassing expectations and delivering surprising science. Scott Bolton, the mission’s Principal Investigator, is back with a thrilling report.
