Ep 481: Rockets pt. 3 – Going Faster, Higher, Farther after Fairing Separation
We’ve seen rockets blast off from here on Earth. But that’s only half the story. Rockets have additional stages to push them into trajectories, like transfer orbits and various orbital maneuvers. Let’s talk about what happens after the rocket is long gone, beyond our sight.
Ep 480: Rockets pt. 2- Multi-stage Boosters
The vast majority of rockets are multi-staged affairs. Why is this? What makes this kind of rocket so successful? Today we look at the ins and outs of multi-stage rockets.

Ep. 476: The Overview Effect
After they’ve been to space, many astronauts report that seeing the world from above has given them a totally new perspective on humanity and the state of our planet. It’s called the Overview Effect. Today we’ll talk about this, and what this perspective can teach us all.
