Ep 485: Docking, Refueling, and Transferring

3/30/2018
More
It’s one thing to get to space. But once you’ve made it there, what do you want to do? You’ll probably want to dock with another space ship, deliver cargo, refuel. Today we’ll talk about how all that happens.

Ep 484: Transfer Orbits and Gravitational Assists

3/23/2018
More
If you want to get around in the Solar System, you’ll want to take advantage of natural gravitational speed boosts and transfer orbits. Whether you’re heading to the outer Solar System or you want to visit the Sun itself, the planets themselves can help you in your journey.

Ep 483: Stopping in Space

3/16/2018

Ep 482: Alternative Ways to Space

3/9/2018
More
Getting to space is all about rockets, but people are trying to figure out other methods that could carry payloads to orbit and beyond. Railguns, airplanes, tethers and more. Today we’ll talk about alternative methods of spaceflight.

Ep 481: Rockets pt. 3 - Going Faster, Higher, Farther after Fairing Separation

3/2/2018
More
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.
