October 30TWiS 234: Living in Lunar Caves - Could We Live Inside the Moon?
In our ongoing quest to develop a moon base, could we possibly utilize the area beneath the surface of the moon in order to make the moon habitable? In this episode of This Week in Space, Tariq Malik and guest host Mike Wall of Space.com talk with Than Putzig of the Planetary Science Institute about a NASA-backed payload bound for the Marius Hills Pit, a roughly 50-meter-wide opening that may lead into a lunar lava tube to gather more data about these formations on the Moon and the possibility of these lunar caves becoming the Moon's first living habitats for humans. Putzig explains how geophysical instruments on a rover could detect hidden voids beneath the surface and measure the size of these lava tubes. We also ask Than how these lava tubes form, what a follow-up robotic explorer could reveal, and how this research fits alongside NASA's Artemis plans for a south polar moon base. Join us!

October 16TWiS 232: The Lunar Dump - Over 800 GB of Moon Data
In this week's episode we turned to Chelsea Gohd, former writer for NASA/JPL and now with Space.com, to talk about the recent large data dump from the Artemis II mission. What was included? Why is this new data important? What observations were made, and what discoveries might result from them? What kind of annotations and notes did the astronauts include that make these observations uniquely valuable? And finally, we talk about Artemis III - what is the mission profile and what are the stakes for SpaceX and Blue Origin?

October 02TWiS 230: Living on Lava Worlds - Atmospheres on Lava-Covered Exoplanets
Think you're having a hot summer? Try living on 55 Cancri-e, a super-Earth with daytime temperatures above 4000 degrees Fahrenheit. Most of these super-Earths orbit frighteningly close to their host stars and have long since had their atmospheres scraped away, leaving them baked, parched rocks. But some, like 55 Cancri, still have dense envelopes of air. How is that possible, when the planet is 20 times closer to its star than our own planet Mercury? Dr. Laura Schaefer explains how molten lava worlds defy the odds. Plus: Starship update, the first orbital data centers, and a new year on Mars.

September 25TWiS 229: Is It Starship's Time? - Test Flight 14 to Orbit
This week it's Rod and Tariq working through the most important space headlines. The big story: Starship could launch test flight 14 as early as Monday the 28th. We've seen lots of tests, but this is the first attempt at an orbital flight, the success of which is necessary for the lunar landing system and eventual retirement of the Falcon 9 and Crew Dragon. Also: Vast starts up a lunar division, Isaacman's relief over delays to China's lunar program, concerns over announced discontinuation of SpaceX's Falcon 9 and Crew Dragon, and yet more money for Boeing's troubled Starliner. This and more on this episode of TWiS!

September 18TWiS 228: What's a HOTOL? - Britain in Space
In the 1980s, as the US space shuttle was just starting operations, the UK embarked on an ambitious project called HOTOL—short for Horizontal Take Off and Landing, a radical, air-breathing spaceplane design. Political and funding shifts in the UK ultimately derailed the project, despite the promising technologies it pioneered. The idea was later restarted as Skylon, with key individuals and refined technologies at its core. This project, too, struggled, ultimately shuttering in 2024. Despite this, the promise of rapid, reusable spaceplanes that can launch and land at airports is still coveted by many countries, and efforts continue. Join Rob Coppinger, author of the definitive book on the topic and editor of the UK's "Spaceflight" magazine, as he tells this fascinating story.

Hold onto your phasers, but it's been 60 years since Star Trek's debut, and the franchise is still going strong. For 40 of those years, Mike Okuda, working with a gifted team that included his wife Denise, has been central to the look, feel, and substance of the Star Trek universe. From the LCARS computer graphical system to alien languages to the designs and color schemes, and even the digital effects remastering of the original series, Mike has been the Cardinal of Canon when it comes to all things Trek. He has also been involved with many more space-related shows, books, and NASA projects. Join us for this very special episode.

September 04TWiS 226: 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 at one business case for newspace.

August 28TWiS 225: 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.
