Exoplanet hunter and artist Natalia Guerrero of MIT reveals the discovery of many more possible new worlds by NASA’s Transiting Exoplanet Survey Satellite.
Astrophysicist Javier Peralta, a team member on Japan's Akatsuki mission, takes us deep into Venus's thick, fast-moving clouds.
Elsa Montagnon is Spacecraft Operations Manager for the European/Japanese mission leaving for our solar system’s innermost planet very soon. She joins us to talk about the long journey ahead.
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 Planetary Society’s solar sail spacecraft was in the middle of a critical test as we spoke with the Society’s Bruce Betts and Jason Davis.
We’re back at Space Symposium for a conversation with SNC’s Mark Sirangelo, leader of that company’s effort to build the Dream Chaser. We’ll also hear a few moments of Bill Nye’s session at the annual gathering as he hosted Bernard Foing and Amy Mainzer.
Happy Yuri’s Night! We’re partying under Space Shuttle Endeavour in the first of two shows featuring interviews from the worldwide celebration of space. Star Trek’s Robert Picardo will talk about his new video newsletter, the Planetary Post, and we’ll visit with Samantha Cristoforetti, who returned last June from 200 days aboard the International Space Station.
Bruce Betts, Jason Davis, Casey Dreier and Emily Lakdawalla gather with Mat Kaplan for a fascinating and informative Planetary Radio Extra year-in-review roundtable discussion.
Drilling through many meters of ice to Europa’s ocean or to the pristine sub-surface layers of Mars will be hard. The Planetary Deep Drill prototype has shown that it may be a practical approach. Join Mat Kaplan and Planetary Society colleagues at the field test site deep in California’s desert.
Journey to Space is both a new and spectacular IMAX movie and an exciting, hands-on exhibition at the California Science Center. We learn about both this week.
Explore Mars revealed the 2015 Humans to Mars Report at a recent conference in Washington. CEO Chris Carberry gives us a quick tour of this inspiring assessment of what it will take to get more than robots to the Red Planet.
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.
Bigelow Aerospace’s BEAM expandable/inflatable space module will be attached to the International Space Station later this year. Mat travels to the company’s headquarters for a conversation with founder and CEO Robert Bigelow.
Joe Liske, host of Hubblecast, is also the top scientist on the European Southern Observatory’s European Extremely Large Telescope (E-ELT), now under construction on a Chilean mountaintop. “Dr. J” tells us what this largest ever telescope will help us discover.
The Planetary Society’s experts look forward to a great year of firsts in the solar system and beyond.
MIT planetary scientist and astrophysicist Sara Seager is on a quest. She wants to find a warm, wet exoplanet with signs of life. It could be Earth 2.0.
Not just landed. Orbited, too. European Space Agency Senior Science Advisor Mark McCaughrean helps us celebrate the Rosetta orbiter and the Philae lander.
MESSENGER has been orbiting the innermost planet for more than three-and-half-years. Principal Investigator Sean Solomon returns with a status report as the mission enters its final phase.
Venus Express Project Scientist Håkan Svedhem tells us about the spacecraft’s harrowing descent into the Venusian atmosphere, what it is currently up to, and what he’d like to see next at that forbidding planet.
24 spacecraft are either busy exploring the solar system or speeding toward an exciting destination. The Planetary Society's Senior Editor takes us on a whirlwind advance tour.
