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!

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?

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.

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.
