NASA has approved development of the NEO Surveyor space telescope. Project lead Amy Mainzer shares her hopes for this vital planetary defense tool.
NASA chose SpaceX’s Starship as the sole winner of its human lunar lander development contract in a move that may also take us closer to Mars.
Elon Musk’s SpaceX nearly failed 15 years ago as it struggled to launch its first rocket. Eric Berger has written about this challenging early era and how it helped create today’s successful, innovative company.
The Coalition for Deep Space Exploration’s Mary Lynne Dittmar talks with Casey Dreier about how and why spacefaring nations prioritize funding for space development and exploration.
Space historian Dr. Roger Launius joins the show to explain why Apollo happened the way it did, how a moonshot briefly became a solution to a national security problem, and why it is unlikely to happen again.
Can NASA return astronauts to the Moon by 2024? Vice President Mike Pence shocked the space community by announcing this ambitious new goal just weeks after the Trump Administration proposed a half-billion dollar cut to the space agency.
The last few days have seen developments that will shape the space exploration plans of Canada and the USA. The Planetary Society’s Kate Howells is a member of Canada’s Space Advisory Board. She reviews the nation’s new space policy.
Mat Kaplan’s Huntsville, Alabama trip wraps up with a tour of the historic and history-making Marshall Space Flight Center. Join him at the control center for research underway on the International Space Station, under a tent where a critical component of the Space Launch System rocket is getting finishing touches, in a conversation about the Fermi spacecraft’s search for the universe’s biggest explosions, and with the Center’s Associate Director for Technical efforts.
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.
Mat’s first-ever four-way conversation with Jason Davis, Casey Dreier and Emily Lakdawalla reviews the biggest 2017 events in space exploration and provides their predictions of what to look for in the new year.
Fifteen years before Sputnik, on a bright 1942 afternoon in northern Germany, a thundering machine of metal and fire pierced the sky, ultimately touching the edge of space for the first time in history. It opened a new era of opportunity and terror with rocket technology. Dr. Michael Neufeld joins us discuss the significance of this test and how it happened.
The human journey to the Red Planet is long and hard, but Mat’s conversation with three NASA Associate Administrators at the Humans to Mars Summit was filled with cautious optimism.
Moon or Mars? Should NASA depend on private companies? What’s the goal of human spaceflight? These questions were debated three decades ago, yet are just as relevant today. Does that mean space policy is stagnant?
The longtime editor of outstanding online space news source Universe Today has just written about nine robotic missions of exploration in
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?
No one is more excited about eclipses than famed solar astronomer and author Jay Pasachoff. He looks forward to the total solar eclipse in August of 2017.
The SETI Institute is about much more than the Search for Extraterrestrial Intelligence. President and CEO Bill Diamond of the Institute explains.
Planetary Society Digital Editor Jason Davis returns with the story of the ten-day trek across the South he just completed with two Society colleagues.
Space historian and policy expert John Logsdon joins Mat Kaplan for a fascinating conversation about how the US could have lost the race to the moon.
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.
