Main Engine Cut Off

NASA and Boeing laid out Starliner’s return-to-flight plan as SpaceX prepares to leave Dragon behind. I talk through the weak demand signal for crewed flight in LEO, how NASA’s commitment to the ISS and commercial stations boxed themselves into this decision, and what to do between here and the Moon.

SpaceX officially announced Starbase Louisiana, and I break down why the site fits Starship’s launch, landing, and orbital architecture so perfectly. I also look at the transition from Falcon to Starship, and the new launch vehicles on the verge of debut.

Founder and CEO of Auriga Space, Winnie Lai, joins me to talk about their electromagnetic launch infrastructure and the path she sees for Auriga across space and defense markets. And yes, we talk about whether this kind of alternative launch architecture is a good fit for Earth, or a better fit for pretty much every other rock in the solar system.

I often talk about SpaceX being an extreme outlier in the industry and how many organizations have tried to replicate their approach, but very few (if any) have been successful. Matt Gjertsen of Built  joins me to share a take on what exactly it is internally that drives their results, how to apply it in other organizations, and to share some perspective on his time at SpaceX leading Training and Development, and from elsewhere in the industry.
