This Week in Space (Audio) ·

2026/10/02

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

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

TWiS 226: Who Owns the Moon? - Capitalism and...

This Week in Space (Audio) ·

2026/09/04

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,

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

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.

We're headed for a space renaissance, and it will be focused on the Moon. The US, China, and international partners of both are vying to land people there and construct a permanent lunar base. Meanwhile, NASA is evolving to embrace commercial enterprise unlike any time in its past, and American lunar efforts are lagging. What are the stakes? Does it matter who returns humans there first? What does the future of lunar commerce look like? Dr. Scott Pace, the Director of the Space Policy Institute at

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.

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

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
