A holiday special! Enjoy this week’s episode of Headlines free. It’s an absolute monster episode—way longer than usual Headlines episodes, I promise—but it’s a great example of what you get when you support the show over at mainenginecutoff.com/support.

Yesterday, I had the chance to visit the Pentagon and sit down with General Chance Saltzman, Chief of Space Operations—the head of the United States Space Force. We talk about the service 6 years into its existence, the state of acquisitions, the threats and space environment today, and what the future may hold for the Space Force when it comes to human spaceflight.

Stephen Clark of Ars Technica joins me to talk about a ton of stories in the news—Jared Isaacman was back in front of Congress, a few Starliner flights have been cut from the ISS manifest, Starship received environmental approval to proceed at SLC-37, Zhuque-3 almost stuck its first landing attempt, the Soyuz launch pad fell apart at Baikonur, and the Space Force has a new mission naming scheme.

Blue Origin is fresh off an incredible few weeks—a successful second launch and first landing of New Glenn, followed by an exciting unveil of upgrades to the vehicle, including an enormous new version, New Glenn 9x4.

Simone D’Amico of Stanford and EraDrive, DJ Bush of NVIDIA, and Al Tadros of Redwire join me to talk about autonomy in space, to get into the specific details of what they’re working on and how it comes together, and what it may do for the industry in the next few years.

Thinking through the chaos that has ensued over the NASA Administrator role, the Artemis 3 lander acceleration movement, the SpaceX Starship HLS update, and a bit on how we actually got here.

Caleb Henry, Director of Research at Quilty Space, joins me (in studio!) to talk about Starlink V3, Starlink satellite relay, Kuiper’s rollout, the Airbus-Thales-Leonardo merger, and the future of Iridium.

Miles O’Brien, science correspondent for PBS News and CNN space analyst, joins me to talk about Starship Flight 11, the current space policy landscape including the ongoing government shutdown, the possible return of Jared Isaacman, and what to do about all the competing budget priorities at NASA.

Phil McAlister, former Director of NASA’s Commercial Space Division, joins me to talk about the Commercial LEO Destinations program, the budgetary issues facing NASA and its human spaceflight programs, and to share his perspective on the last (and next) few years in these areas.

NASA selected Blue Origin to (maybe) deliver the once-cancelled VIPER rover, modified Sierra Space’s ISS resupply contract which likely puts the nail in the coffin of Dream Chaser, and released the draft of its new commercial space station strategy. All different stories with one message: prove it. But maybe not in a good way.

Caleb Henry, Director of Research at Quilty Space, joins me to talk about EchoStar’s spectrum sales and constellation cancellation, SpaceX’s spectrum purchase, and the financials of Starlink.

Casey Handmer, Founder of Terraform Industries, joins me to talk about the state of NASA in 2025, talent acquisition and retention, productivity, and so much more.

Tom Marotta of The Spaceport Company joins me to talk about the executive order this week focused on commercial space regulatory reform, what problems it seeks to solve, his experience on both sides of those issues, and how we should understand the positioning of the order.

Michael Moreno, VP of Strategy at Lunar Outpost, joins me to talk about what they’ve been up to at the company, the NASA Lunar Terrain Vehicle Services contract, the idea of services as a business on the Moon, and more.

A special simulcast of this week’s Off-Nominal—the other show I do, if you somehow haven’t heard of it!—because it’s exactly the topic list with exactly the guest I had up next on my list. I’m joined by Adrian Beil of NASASpaceflight to talk about the recent mayhem at Starbase, and to kick around European space policy topics in the run up to the ESA Ministerial later this year.

Lori Garver, former NASA Deputy Administrator, joins me to talk about the chaos of the last week: the withdraw of Jared Isaacman’s nomination for NASA Administrator, Starship Flight 9, and of course, the wild public breakup of Elon Musk and President Trump.

Mark Albrecht joins me to talk about his time on the Trump 2024 Transition Team, the thinking behind some of the policy decisions we’re starting to see in the space and national security spheres, and more.

We take a tour of Marotta Controls in Montville, New Jersey, to see how they work, how they develop, produce, and test products at rate, and we learn about the most feared topic in space—valves!

Caleb Henry, Director of Research at Quilty Space, joins me to talk megaconstellations, the hypersonics industry, and more.

Jared Isaacman was in Congress for a confirmation hearing for his nomination as NASA Administrator, which was followed up by reports of huge proposed budget cuts at NASA and NOAA. And as expected, SpaceX, ULA, and Blue Origin all received awards for NSSL Phase 3 Lane 2.
