At this point, can anyone compete with SpaceX? Love him or hate him, Elon Musk and his cadre of very talented employees and partners have built the most remarkable launch service in history, increasing the US launch rate from a handful to over 100 per year in less than a decade. Eric Berger--Senior Space Editor at Ars Technica and author of "Liftoff" and "Reentry," two books about Musk and SpaceX--joins us. We discuss the rise of SpaceX, Musk's future in US politics and the market, and what...

On this episode, we take a look at how the space workforce of the future will be educated and, perhaps more importantly, engaged with Dr. Rick Jenet of Expanding Frontiers. Located in Brownsville, Texas, just a stone's throw away from SpaceX's Starbase, expanding Frontiers works with underprivileged communities to bring them into 21st-century space-related trades and to encourage individual entrepreneurship. Dr. Jenet has a fascinating history as well, attending MIT as an undergraduate and...

Many of us have visited the various displays of space shuttles around the US, and it's always a spectacular sight. The shuttle orbiter was huge, and seeing in any configuration is inspirational. Notably, the California Science Center is completing a display of the Endeavor in a launch configuration, which is unique among shuttle installations. But the very first shuttle mockup ever constructed will soon go on public display in its birthplace in Southern California, the city of Downey. This is...

This week, we're taking a broad look at the progress of America's Artemis lunar landing program, space science in general, and the challenges to Western space plans posed by a fast-rising Chinese space program. Joining us is the uniquely qualified Dr. Greg Autry--the Associate Provost for Space Commercialization and Strategy at the University of Central Florida, visiting Professor at Imperial College London, former NASA transition team member, and author of "Red Moon Rising." We'll also...

This week, we're diving deep into some really clever and cutting-edge tech for Martian habitats... made from fungus! Dr. Lynn Rothschild of the NASA Ames Research Center has been working for years on how mushroom mycelia might be utilized as a habitat-building resource. It's quite fascinating--the organic material can be used to make bricks, to create shaped structures, and even to create an "astropharmacy" to supply certain compounds needed by the crew of a Mars excursion! And it is...

It's a question that rivals the meaning of life itself: which is better, Star Trek or Star Wars? Of course, they are very different, and that's really the core of it--one is a sweeping fantasy adventure incorporating the "Hero's Journey," while the other is a science fantasy wrapped around a morality play. In the end, we love them both. But there is a bit of cultural (and perhaps generation) divide here, and someone has to put Tariq in his place. Join us for this civilization-shattering...

NASA's planetary exploration program is in trouble. The Mars Sample Return program is verging on cancellation, and the VIPER mission to the moon already has been. Both are critical precursors to human exploration of these places, as Dr. Jim Bell of Arizona State University will tell us. We need to know more about the surface of Mars--with direct, in-the-lab studies of Mars rocks--and we certainly need to understand where the volatiles--another name for water and other resources of value--are...

Devon Island, a polar desert in the High Arctic, is one of the most convincing Mars analogs on Earth. That's why Pascal Lee built his NASA-affiliated research base there. On this episode he returns to discuss his summer field work, Martian volcanoes, and to discuss possible alternatives to NASA's plans for the Artemis lunar base.There's a lot to know, and he brings deep passion—and some controversy—to the conversation! Headlines: Polaris Dawn mission success: The crew completed the...

Starliner is back and, by all accounts, could have returned with its crew had it been necessary. However, with NASA's "safety forward" approach prevailing, the spacecraft landed uncrewed on September 6, three months after it docked with the International Space Station. Now, the work begins to try to solve the problems- largely software changes, dealing with balky thrusters, and helium leaks- so that the Starliner Crew 1 can fly next year. But how did we get here? What's NASA's take on the...

We all know the ISS is living its last days and will be deorbited sometime around 2030... but what's coming up next? For episode 127, Max Haot of VAST joins us to discuss his company's first space station, called Haven-1, set to launch in 2025. For a company just just a few years old, VAST has made impressive progress toward what is likely to be the first private crewed space station in history. Subsequent plans include a larger orbital habitat with artificial gravity and much more. It's an...

As if election season wasn't scary enough, now we have rogue planets to worry about! Out in the vast darkness between star systems, these worlds wander through the interstellar void, sometimes in pairs, and when they encounter a solar system, havoc can result. Add to the fact that they are hard to see, and you have a recipe for worry. Fortunately, we have astrophysicists like Dr. Rosalba Perna on the job, learning more about these strange, errant planets daily! Add to that the ever-increasing...

It's the end of summer, and that means it's time to go back to school—in our case, space school! There's a lot going on, a lot coming up, and a whole lot to know about the next 9 months in space. What can we expect from SpaceX? How are the outer solar system missions proceeding? What about the new rocket engines for the Artemis program? What are we doing about orbital debris? Are we really in a new space race with China? And much more, including that most vexing of questions: what's up with...

Czarina Salido, a physics graduate of mixed Mexican and Native American heritage, founded Taking Up Space in 2014. This nonprofit aims to address the underrepresentation of women, particularly Native American girls, in STEM fields. Based near Tucson, the organization provides mentoring, instruction, and Space Camp scholarships to disadvantaged girls on a nearby reservation. Salido's initiative has gained recognition in the STEM community and inspired similar efforts nationwide. Join us as we...

Each year, there are a handful of impressive meteor showers, and one of the largest and best this year will be the Perseids. The quarter moon will set just before midnight, when the shower activity peaks, and if you're in a dark spot expect to see maybe 50-60 shooting stars per hour. Steve Fentress, veteran astronomer and planetarium director, joins us to provide viewing tips, a meteor shower, and star lore over the ages, and more. Headlines: Starliner - Boeing's Starliner spacecraft...

It's been said that Mars ain't the kind of place to raise your kids, and that's certainly the assertion of the popular 2023 book, "A City on Mars" by Kelly and Zack Weinersmith. In fact, they question the future of settling humans off Earth in its entirety. Certainly, it will be challenging, but is it impossible? Are there reasons we should not go? We gathered together two of our favorite experts on the topic, Dale Skran, the COO and SVP of the National Space Society, and Mr. YouTube himself,...

A nova is a star that periodically sheds mass in a huge flare-up of light and energy. This week, astrophysicist Dr. Carlos Badenes from the University of Pittsburgh joins us to discuss a star that should be going nova in the next few weeks--and will be visible in the night sky for about 6-7 days! T Corona Borealis (TCrB) is a binary system comprising two stars in the constellation Corona Borealis that bursts into magnitude 2 (as seen from Earth) about every 80 years--and should do so again by...

In this episode of This Week in Space, Rod Pyle and Tariq Malik dive into the 55th anniversary of the Apollo 11 moon landing, discussing the mission's highlights, challenges, and historical significance. They also cover recent space news, including Elon Musk's plans to move SpaceX's headquarters to Texas, the Falcon 9 upper stage failure, and the cancellation of NASA's VIPER rover mission. Looking ahead, the hosts speculate on the future of the Artemis program and the political landscape's...

If you saw the movie "Gravity," you have a sense of the dangers of orbital debris—and the risk is very real. More than 25,000 objects over four inches in diameter are tracked by the US Space Force, and millions of others are smaller or untracked—everything from derelict satellites to dead rocket stages to bits of shrapnel and even just chunks of frozen rocket fuel is there. And even something the size and mass of a paint chip, traveling at orbital speeds, can take out a window of a...

For many of us, dark matter and dark energy are two of the least understood areas of cosmology and astrophysics. This week, we invited Alina Kiessling and Jason Rhodes, both Research Scientists at NASA's Jet Propulsion Laboratory, to explain these concepts and their broader implications for cosmology, exoplanet research, and more. Both of them are working on major space telescope projects to research "dark physics," as they will explain. Guest co-host Isaac Arthur asks compelling,...

For decades we've seen images of huge glass domes on the moon and Mars, but the reality of building settlements off-Earth is likely to look much different. This week we're joined by Evan Jensen of ICON Build, a company that, in just a few years, has created housing across Texas via 3D printing. Now, in association with NASA, they are also investing heavily in researching how to 3D print habitats on the moon and one day Mars. It isn't easy working in a vacuum--water freezes and evaporates...

In the world of space podcasts, the Space and Things podcast is a keeper (along with ours, of course). The brainchild of Emily Carney, founder of the Space Hipsters on Facebook, and singer/songwriter Dave Giles, Space and Things brings us some premiere guests in the space sector. Subjects are always compelling, and as we well know, that takes work. We'll dive into the intricacies of creating--and maintaining--a quality space podcast and the success of Emily's Facebook group, the Space...

We see the sun every day as it rises and sets... it's one of the few constants in life. But it's a very dynamic body, throwing minor temper tantrums regularly. As it happens, we're at the peak of its 11-year cycle of activity and there's a lot going on! Dr. Alex Young, the Associate Director for Science in the Heliophysics Science Division at NASA's Goddard Space Flight Center, joins us to talk about the sun, solar activity cycles, the recent solar storms that have given us auroras and some...

Well, we waited, we waffled, and we joked... but Boeing's Starliner finally made good! Seven or so years after their projected crewed flight date, the second provider of crew delivery to the International Space Station finally succeeded in sending two astronauts, Butch Wilmore and Sunita Williams, to the ISS. Despite a few problems with (sigh) valves, helium tanks, and thrusters, the mission appears to be going swimmingly. Then, just a day later, SpaceX launched a Starship on a fourth test...
