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.

T+326: Artemis II Underway

There was a lot of news in NASA’s Ignition event last week, and I break down what actually matters: not whether Jared Isaacman’s timelines are realistic, but how this new roadmap strips away architectural dependencies and forces the real bottlenecks into the open. I talk through Gateway’s cancellation, the possible path away from SLS and ICPS, what this means for lunar landers and international partners, and why NASA’s new philosophy feels so different from the past.
