Planetary Radio: Space Exploration, Astronomy and Science

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.  He has much to say to Mat Kaplan about the future of space exploration and humanity in this week’s show.  NASA has announced two exciting papers based on discoveries by Curiosity, the Mars Science Laboratory Rover.  Emily Lakdawalla has the straight story.  And we’ve got one more signed copy of “Chasing New Horizons” to give away in this week’s new space trivia contest.

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.  PlanetVac replaced one foot of a Masten Space Systems Xodiac rocket for back-to-back hops across a test site.  We also talk with Masten CEO Sean Mahoney. Planetary Society Chief Scientist Bruce Betts also made the trip.  He’ll also open a super massive contest for PlanRad listeners in our What’s Up segment.  See images and video of the PlanetVac Xodiac flight test and learn more here:  http://www.planetary.org/multimedia/planetary-radio/show/2018/0606-planetvac-xodiac-test.htmlLearn more about your ad choices.

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. Mat Kaplan talks with the former NASA Chief Scientist about her new job and how the museum serves to inspire and inform millions each year.  Senior editor Emily Lakdawalla prepares us for an exciting encounter between Japan’s Hayabusa 2 spacecraft and asteroid Ryugu.  Harry Potter fans, rejoice!  Bruce Betts corrects his correction of an astronomical observation by Harry and his classmates. We also offer another signed copy of Chasing New Horizons: Inside the Epic First Mission to Pluto.

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 entire dramatic tale has now been told by Principal Investigator Alan Stern and his co-author, astrobiologist David Grinspoon.  They join Mat Kaplan to talk about their book, Chasing New Horizons—Inside the Epic First Mission to Pluto.  A signed copy of the book will go to the winner of this episode’s space trivia contest.  Emily Lakdawalla has returned from an international gathering of Mercury scientists with a special report.  The Planetary Society’s Senior Editor also marks the launch of a Chinese lunar orbiter.  Learn more about this week’s topics and see images here: http://www.planetary.org/multimedia/planetary-radio/show/2018/0523-stern-grinspoon-chasing-new-horizons.htmlLearn more about your ad choices.

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.  It’s not just about defending our planet.  We are learning the origin story of Earth and other worlds.  Bruce Betts also shares a story or two, along with a new space trivia contest, in this week’s What’s Up segment.  Learn more about this week’s topic and see images here: http://www.planetary.org/multimedia/planetary-radio/show/2018/0509-amy-mainzer-neowise.htmlLearn more about your ad choices.

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? Will there be new commercial space stations in the near future, and will they serve NASA's needs? Also, the confirmation of Jim Bridenstine as NASA Administrator.

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.  Principal Investigator Bruce Banerdt came to Planetary Society headquarters barely a week before launch for a long and fascinating conversation. Planetary Society CEO Bill Nye says the European Space Agency’s Gaia spacecraft has mapped our galaxy as never before.  Bruce Betts will help us explore a bit of the Milky Way in this week’s What’s Up segment.
