    T+325: Ignition

    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.

    T+323: The Artemis Roadmap Shakeup
