Main Engine Cut Off

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.

Episode T+318: General Chance Saltzman, Chief of Space Operations, United States Space Force

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 aquisitions, 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.

Episode 214 - Blasting Through the Pork Chop

Off-Nominal

Jake and Anthony do a good ol’ news roundup—Jared Isaacman may be back as NASA Administrator, Stoke Space raises a ton of money, New Glenn gets ready for its next launch, and we have thoughts about the communication of phasing orbits.

Episode T+310: NASA’s “Prove It” Era

Main Engine Cut Off

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.
