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.
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.
Host Mat Kaplan begins a two-episode visit to Huntsville and the Marshall Space Flight Center, recorded this week at the US Space and Rocket Center with astronaut Don Thomas, 94-year-old Apollo engineer Alex McCool, and Alabama Senator Doug Jones.
Pluto passed in front of a star on the evening of August 14. Mat Kaplan joined pro and amateur astronomers on a mountain to observe this rare event. It may reveal more about the dwarf planet’s tenuous atmosphere and other properties.
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.
The longtime editor of outstanding online space news source Universe Today has just written about nine robotic missions of exploration in "Incredible Stories From Space: A Behind-the-Scenes Look at the Missions Changing Our View of the Cosmos."
Astronomers Jay Pasachoff and Alex Filippenko join us for a conversation about their newest version of their monumental textbook, "The Cosmos." Emily Lakdawalla helps us say good morning to the just-awakened Rosetta spacecraft, while Bill Nye is fascinated and puzzled by what looks like a jelly doughnut on the Martian surface.
Take a spacecraft that can no longer survey the realm of galaxies and repurpose it to discover thousands of much nearer asteroids and comets. Put it to sleep for 2.5 years, then wake it up and start discovering even more! JPL’s Amy Mainzer is Principal Investigator for NEOWISE, the mission using this amazing space telescope.
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 annual fall meeting of the American Geophysical Union revealed lots of science, some of it astounding. Emily Lakdawalla was there with Advocacy and Outreach Coordinator Casey Dreier, whose news was not quite as good.
Alyssa Rhoden studies Jupiter’s moon Europa…from a distance. She, many other scientists and millions of space exploration fans around the globe want to see a mission to this ice world that hides a vast, warm ocean. That’s why she and several colleagues have created Destination: Europa, and they want your help.
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.
