486: Particle Physics Update Astronomy Cast 486: Particle Physics Update by Fraser Cain & Dr. Pamela Gay
It’s time for a news update. This time from the field of particle physics. It turns out there have been all kinds of new and interesting particles discovered by the Large Hadron Collider and others. Let’s get an update from Pamela.
485: Docking, Refueling, and Transferring Astronomy Cast 485: Docking, Refueling, and Transferring by Fraser Cain & Dr. Pamela Gay
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.
484: Transfer Orbits and Gravitational Assists Astronomy Cast 484: Transfer Orbits and Gravitational Assists by Fraser Cain & Dr. Pamela Gay
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 March 16, 2018
It’s one thing to get from Earth to space, but sometimes you want to do the opposite. You want to get into orbit or touch down gently on the surface of a planet and explore it. How do spacecraft stop? And what does that even mean when everything is orbiting?
482: Alternative Ways to Space Astronomy Cast 482: Alternative Ways to Space by Fraser Cain & Dr. Pamela Gay
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.
481: Rockets pt. 3 – Going Faster, Higher, Farther after Fairing Separation Astronomy Cast 481: Rockets pt. 3 – Going Faster, Higher, Farther after Fairing Separation by Fraser Cain & Dr. Pamela Gay
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 manouvers. Let’s talk about what happens after the rocket is long gone, beyond our sight.

This was a special Q&A; episode Pamela recorded while Fraser was in Iceland.
480: Rockets pt. 2- Multi-stage Boosters Astronomy Cast 480: Rockets pt. 2- Multi-stage Boosters by Fraser Cain & Dr. Pamela Gay
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.
479: Rockets pt. 1- What Does “Single Stage To Orbit” Really Mean? Astronomy Cast 479: Rockets pt. 1- What Does “Single Stage To Orbit” Really Mean? by Fraser Cain & Dr. Pamela Gay
To celebrate the launch of the Falcon Heavy, we figured it was time for an all new series, this time on the rockets that carry us to space. Today we're going to talk about why single stage to orbit rockets are so difficult to carry out.
478: Apollo 8 with Paul Hildebrandt Astronomy Cast 478: Apollo 8 with Paul Hildebrandt by Fraser Cain & Dr. Pamela Gay
On Christmas Day, 1968 Frank Borman, James Lovell and William Anders became the first human being to see the far side of the Moon. Their mission, of course, was Apollo 8, the first time human beings had ever left Earth orbit and seen the far side of the Moon. Today …
