Astronomy Cast Ep. 764: Cleared For Launch!

https://www.youtube.com/watch?v=4GhRypmWaCY


Streamed live September 17, 2025.


This week, we look at the process behind rockets getting licensed
to launch, and everyone around the pad getting notified to stay
away as T-0 approaches. (Can you say "errant boat"?) We have a
saying around here: “One does not simply book a return trip from
a rocket launch.” That’s because they are an intensely complex
chain of events that need to go right before it’s wise to let
that rocket leave the launchpad.
