Episode T+158: Doug Loverro Resigns, and a Bit About the Artemis Accords

Main Engine Cut Off

The head of human spaceflight at NASA resigned last week, just before the most important crewed launch the agency has seen in a decade.

I give some thoughts on the implications of the departure, and also cover a recent development in international space politics—the Artemis Accords.
