SETI Institute scientist Jason Rowe returns to tell us about the smallest exoplanet so far that has had its size and mass determined. Jason also talks with Mat about our ever-expanding knowledge of these worlds that circle faraway stars.
Two visits with the Planetary Society Senior Editor this week, as Emily first provides an update on the Rosetta comet mission and then returns with an extended look ahead at the New Horizons Pluto encounter next week.
We’ve already brought you Planetary Radio Live from the 2015 PDC near Rome, Italy. Now you’ll hear a small sampling of the scientists, engineers, policymakers and media experts who spent five days considering how humanity will respond to a potentially disastrous threat. Bruce Betts celebrates the great Jupiter-Venus conjunction in What’s Up. Bill Nye and Emily Lakdawalla return next week.
After a roller coaster ride that included a maddening eight-day silence, the LightSail test mission finally achieved all of its major goals. Leaders of the mission team gathered on June 10th to take questions from the media, and share their thoughts and emotions with the general public. Today’s show presents highlights of that briefing. Emily Lakdawalla is seeing things on Pluto, and she’s not alone. Bruce Betts takes Mat Kaplan on a walk in space during this week’s What’s Up segment.
This special edition takes you behind the scenes on May 20, 2015 as LightSail is lifted into orbit. You’ll hear the thrilling launch, meet key team members as they prepare for the big moment, and hear a special status report from Planetary Society CEO Bill Nye.
It’s the biggest dwarf planet between here and Pluto, and it has a new permanent resident. The Dawn spacecraft is orbiting Ceres in the asteroid belt, revealing it as never before. What are those bright spots anyway? We spend time with Dawn’s Chief Engineer and Director, Marc Rayman.
Humankind’s arrival at Pluto is barely two months away. The science and images have already started to flow from New Horizons, according to the mission’s Principal Investigator, Alan Stern. Alan returns to Planetary Radio this week.
We open with the countdown to destruction—the MESSENGER spacecraft’s impact on Mercury ended its spectacularly successful mission. Principal Investigator Sean Solomon joins us immediately after this big finish.
The road to space has been a rocky one for most spacecraft, and LightSail is no different. Challenges remain even with the May 20th launch of a test mission approaching. Embedded LightSail reporter Jason Davis checks in with the latest news.
Planetary Radio Live was the only public event at the just-completed Planetary Defense Conference in Italy. Join us for excerpts from an all-star celebration of worldwide efforts to find, track, characterize and eventually deflect killer Near-Earth Objects.
Senior Editor Emily Lakdawalla has returned from the Lunar and Planetary Science Conference in Texas with the latest revelations about our solar system. She shares them in an extended report.
6,000 job-seekers came to the new Long Beach, California home of Virgin Galactic’s LauncherOne rocket on a recent morning. We sit down with CEO George Whitesides for a conversation about this new effort and the return of SpaceShipTwo.
Planetary scientist and author Jim Bell has just written “The Interstellar Age—Inside the Forty-Year Voyager Mission.” He talks with Mat Kaplan about the magnificent grand tour of the outer solar system that is now headed toward the stars.
ARM is the Asteroid Redirect Mission, and sometimes it seems that it doesn’t have a friend in the world. But it does, and Jonathan Goff of Altius Space Machines is one.
The Beagle 2 Mars lander disappeared after it separated from the Mars Express orbiter on Christmas Day, 2003. Eleven years later, it has been found, partially-deployed on the Martian surface. Longtime Beagle 2 mission leader Mark Sims tells the story.
We’ll visit the Jet Propulsion Lab on its Icy Worlds Day to learn more about spacecraft exploring Ceres, Enceladus and Europa from leaders of these missions.
Robina Shaheen and Mark Thiemens tell us how an ancient Mars meteorite has revealed much about the red planet. Mat holds a tiny fragment of the rock in their UC San Diego lab.
The Planetary Society has just announced that LightSail will be launched into orbit on its first test flight in May. We’ll talk with Project Manager Doug Stetson and embedded LightSail reporter Jason Davis about what to expect.
