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.
We've added a new way to donate to 365 Days of Astronomy to support editing, hosting, and production costs.
