https://www.youtube.com/watch?v=87imhw2ljNU Hosted by: Fraser Cain (@frasercain) and Dr. Pamela L. Gay (@CosmoQuest) Streamed on October 3, 2026.

We fall into the tyranny of the rocket equation and discover what it takes to escape Earth's gravity and head off into deep space.   We removed all ads from the show.
