He has also been involved with many more space-related shows, books...
Who Owns the Moon? - Capitalism and Property Rights in Space
Capitalism—and a strong profit motivation—has driven enterprise for centuries. Two notable examples are the East India Company and the US transcontinental railroad, and the various tycoons who built it. In neither case, by today's standards, were the operations fair or ethical on a number of fronts. Can we do better in space? Dr. Rainer Zitelmann joins us to discuss capitalism and the importance of extraterrestrial land ownership as an enabler of human expansion off-Earth. He's got a lot to say, and not all of it is what you might expect. Join us for this fascinating and informative look...
Get a Grip! - New Technologies for Orbital Salvage
The mitigation of orbital debris is an increasingly serious problem that has not gotten enough attention, but this is changing. Commercial companies are addressing orbital debris, and one of them, KMI Space, has flown its experiments aboard the International Space Station, performing over 170 individual rendezvous-and-grab operations. The results are very promising, and the company is moving ahead with ever more ambitious designs. Adam Kall of KMI joins us to discuss their work on the ISS, the goals of the company, and how nature—via the humble octopus and gecko lizards—may have provided the answers for this vexing problem.
...The Science of Artemis - What We'll Do on the Moon
It has been said that the Moon is a harsh mistress, and nowhere is this more apparent than at the lunar south pole. That is, however, where the Artemis program is headed, and we need to figure out how to best explore the region. Dr. David Kring of the Universities Space Research Association's Lunar and Planetary Institute joins us to explore the where, whys, and hows of the Artemis Program's lunar exploration plans, and the answers--and risks--that await us.

How to Invade Earth in 22 Easy Steps - With Rich Edwards
We've all seen the movies... the aliens come to Earth, the aliens overcome the inferior humans, and the aliens fall prey to something dumb they overlooked, like microbes, Windows 95, or most absurdly, water. From the 1950s through yesterday, some of the best movies we've seen were about the invasion of our planet. They can be clever, scary, or even downright dumb, but they are all fun. Veteran space writer Rich Edwards joins us to give advice on how to repel the invaders!

Starship Can Float? - Roman Space Telescope Ready to Launch!
Rod Pyle is out this week, so Rick Jenet of the National Space Society joins Tariq Malik this week to talk about SpaceX's Starship Flight 13, which deployed new Starlink V3 satellites and stunned viewers when the ship survived reentry intact enough to float in the ocean for days afterward. They also discuss NASA's Roman Space Telescope, now just a month from launch, and an in-progress emergency effort to save the ailing Swift Space Observatory using a servicing spacecraft that is itself now experiencing technical trouble. Finally, they look into Boeing's continued Starliner delays and India's first successful private orbital...
First on Mars - The 50th Anniversary of Viking 1
This week, we cover how Starship Flight 13 finally prepares to launch amid a legal battle over SpaceX's proposed land swap at Starbase, plus a Chinese Long March 3B rocket gets struck by lightning during liftoff, yet still delivers its satellite safely. Then, guests Dr. Pascal Lee and astrobiologist Dr. Penny Boston join the show to mark the 50th anniversary of Viking 1's landing on Mars and revisit the mission's groundbreaking life-detection experiments and the decades-long controversy over what they actually found. The conversation traces Mars exploration from the earliest Mariner flybys through Viking's ambiguous, still-debated results—later explained by pe...
SpaceX Goes to War! - And Other Space Headlines
This week we're jumping into the space headlines for the past few weeks. It's been busy, and some exciting things are happening! A couple of companies are moving into the space solar power arena--something we've long advocated--and that's welcome progress. Starship is set to fly Starship test number 13, and a lot is riding on this--the system is overdue for some proof of concept to keep up with NASA's HLS contract. An exoplanet spotted a decade ago has shown signs of a potentially habitable atmosphere; there are landslides--big ones--on Pluto, and evidence of "space candy" sugars in an interstellar cloud...
Which Way to the Moonbase? - With Dr. Pascal Lee
We've been hearing a lot about NASA's new moonbase plans, and they are ambitious. Starting with Artemis V (so far), the US plans to begin preparations for a permanent base situated in the south polar regions of the moon. Details are somewhat fluid, but one thing stands out: the poles are likely to be the most challenging places to set up shop in an already hostile environment. Planetary scientist Dr. Pascal Lee joins us to discuss moonbase siting options and why the poles may not be the best choice at first.

Kabooms, Starship, and a Moon Base - What New Glenn's Explosion Means for NASA's Moon Base
What a wild week in space news! We were all set to discuss Starship Test Flight 12 and NASA's recent press conference updating their lunar base plans, when on Thursday night, Blue Origin lost a New Glenn rocket on the pad during a static test. The explosion appears to have severely damaged the launch structure, LC36, along with the loss of the rocket. Fortunately, there were no casualties. But this does throw NASA's schedule for returning American astronauts to the moon into question, given that the agency had recently signaled their choice of Blue Origin's Blue Moon lander for Artemis 4...
Oysters in Space - With Jacob Scoccimerra of Monolith Space
When one ponders the diet of Mars-bound astonauts, oysters don't often come to mind... but they should. As it turns out, the plucky bivalves have much to offer space voyagers, including water filtration and a ready source of protein. Jacob Scoccimerra, formerly of Nanoracks and now with Monolith Space, initiated a research project with students from the Harrisburg University of Science and Technology, to design, build, and operate a closed-circuit, automated support environment for oysters in a simulated space analog. It's a fascinating discussion that may leave you hungry.

ESCAPADES at Mars - Dr. Robert Lillis of the Mars ESCAPADE Mission
Poor Mars. After a warm, wet childhood, the planet dried out and became cold and arid. And why? Mostly because it lost most of its atmosphere, scraped away by solar radiation. NASA's Maven mission studied the phenomenon of atmospheric loss for years, but has now gone silent. Enter Mars ESCAPADE—the Escape and Plasma Acceleration and Dynamics Explorers—twin orbiters that will study the loss of Martian atmosphere more closely than ever before. The mission has been executed at a budget price. was largely built by industry upstart Rocket Lab, and launched on a New Glenn rocket. It will arri...
Astronauts for America - The Best of the Best Speak Out
Many of us grew up idolizing astronauts as the best of the best that America—and other nations—have to offer. After leaving NASA, many of them go on to relatively routine careers in business or academia, but some stay "on mission" and continue striving to improve the human condition. The 100-plus astronauts behind Astronauts for America, led by Garrett Reisman and Steve Lindsey—a Democrat and Republican—have decided to speak out about their concerns for our democracy. As the nonprofit's website says, "Astronauts For America is a nonpartisan organization of former NASA astronauts who have sworn to defend t...
Lander, Lander, Who's Got a Lander - Will SpaceX or Blue Origin Touch Down First?
Lander, lander... who's got a lander? With NASA planning orbital tests of the Artemis landers in 2027 and a crewed landing in 2028, the pressure is on for SpaceX and Blue Origin to make good on their Human Landing System contracts. Who's actually going to put American astronauts back on the Moon first? This week's episode digs into the high-stakes race between the companies, surfacing new details and doubts about whether either lander will be ready in time. Both have to fly into Earth orbit, refuel multiple times, and perform robotic test landings on the moon (in addition to the Artemis...
What, This Again? - Attempted Cuts to the NASA Budget
As you have doubtless heard, the White House has once again proposed drastic budget cuts of about 24% for NASA's 2027 budget. It's deja vu all over again for us, as we followed an almost identical story last year. And as with last year, Congress has signaled the new budget to be DOA. This time, however, we had a NASA administrator in the seat when this budget arrived and he said he could work with it—despite a near halving of the NASA science budget and proposed cancellation of well over 50 science missions, many already successful and returning great science after th...
I Want to Believe - When We Meet the Aliens
What happens next when science can confidently announce the discovery of an alien life form? Whether it's a fully functioning civilization or a lowly Martian microbe, the implications are vast. Dr. Brianne Suldovsky of Portland State University has studied this mostly ignored question and come up with some interesting conclusions--and, like the best science, more questions. How this can best be communicated in an age of mistrust in large institutions and science is a vexing one, and the conversation looked at it from a variety of angles. And--it was fun. Join us!

Artemis Imminent - Artemis II Back on the Pad!
We've waited, and we've waited, and it looks like Artemis 2 might be ready to go in early April! It's moved back to the launch pad, LC-39B, and will begin preparations for a launch as early as April 1. There will be no wet-dress rehearsal this time — associate administrator Lori Glaze said in a recent press conference that once they fuel successfully, she just wants to go to launch. The crew of Artemis 2 will soon arrive at KSC for pre-launch quarantine, as will Tariq, who will be covering the launch. We invited Mike Wall, the spaceflight and tech editor at Sp...
Born to Explore - With Jay Gallentine
When most people think about deep space exploration, management acumen is generally not the first thing they settle on—but without it, no robotic mission would ever succeed.
