CEO Randa Milliron introduces us to Interorbital Systems, which wants to put your payload in orbit for as little as $8,000. Can they do it?
MAVEN, the Mars Atmosphere and Volatile Evolution orbiter, has gone a long way toward solving the mystery of the Red Planet’s missing water and air. The University of Colorado’s Nick Schneider says it is also revealing gorgeous clouds, auroras and glowing skies.
Marilynn Flynn, Simon Kregar and Rick Sternbach are masters of space art. They talk about how their work furthers science and captures the imagination.
Space historian John Logsdon remembers American hero John Glenn. Planetary Society CEO Bill Nye was a big fan of the Friendship 7 astronaut—less so the new Star Wars movie. Then we get an update on the Giant Magellan Telescope from Patrick McCarthy.
The SETI Institute is about much more than the Search for Extraterrestrial Intelligence. President and CEO Bill Diamond of the Institute explains.
The National Geographic Channel’s “Mars” miniseries has begun. Mat Kaplan attended a kickoff for the ambitious docudrama last summer. You’ll hear from series technical advisor Bobby Braun, author of “The Martian” Andy Weir, Cosmos creator Ann Druyan and more.
Host Mat Kaplan traveled to California’s Mojave Desert for a tour of Virgin Galactic’s The Spaceship Company, where the second SpaceShipTwo was built and is undergoing flight tests. TSC Executive VP Enrico Palermo was his guide.
Mat Kaplan talks with Matt Taylor, the Rosetta Project Scientist, just two weeks after the spacecraft touched down on 67/P.
How did the Voyager spacecraft manage to weave their magnificent way through the outer planets of our solar system? Mission Design Manager Charley Kohlhase led the team that crunched the numbers to select the best possible trajectory from 10,000 candidates.
The Night Sky Guy, Andrew Fazekas, talks about his beautiful new, Star Trek-inspired guide to the real wonders of astronomy.
We take a deep dive into new space legislation working its way through the US Senate. It embraces Mars and NASA's big rocket. But Elon Musk and SpaceX just announced an ambitious new plan to colonize Mars. Does this upset the political establishment? Or will they find a cold reception in the halls of Congress? Also, where does science fit into the politics of space?
The European Space Agency’s magnificent Rosetta mission ended last week as the spacecraft gently touched down on the comet it has revealed.
Steep canyons on Saturn's moon Titan are filled with liquid methane. That's the discovery just announced by an international team of Cassini scientists, including Alex Hayes.
In our third episode, we debate the risks and rewards of tying the future of a Europa mission to the fate of NASA's massive Space Launch System rocket. Also, NASA just announced that the next Mars rover will cost $2.4 billion—$900 million more than initially thought. But the mission is not considered over budget. Why not? Lastly, the U.S. just generated 50 grams of Plutonium-238, the largest amount in nearly thirty years. We celebrate the successful effort to create this critically important, though highly toxic, power source for deep space spacecraft.
Philip Lubin and his former student Travis Brashears have had quite a year. Their bold plan to send tiny probes to nearby stars is now supported by NASA and the Breakthrough Starshot $100 million dollar initiative. Hear their amazing story.
We celebrate the 47th anniversary of the first moon landing with the reprise of a conversation with author and NBC space reporter Jay Barbree about his trusted friend Neil Armstrong.
This month Jason Callahan, Casey Dreier and Mat Kaplan ask whether the Moon vs. Mars human destination debate makes sense, highlight a new report on the science potential of CubeSats by the National Academies, and explain how a thrilling planetary science mission like Juno gets a thumbs up from NASA.
Space art and science fiction joined science fact at the 2016 Contact Conference in Sunnyvale, California. We talk with three well-known visionaries.
In the premiere of this new monthly series we briefly examine the latest move by the House of Representatives in the game of NASA's budget and then discuss what Lockheed Martin's new
Three NASA leaders talk with host Mat Kaplan about the progress we're making toward leaving footprints on the Red Planet.
