A Titan Looms | Episode 2

09/08/17 • 28 min

The Tardigrade is on its way to Titan, the biggest moon of Saturn. We're about to break through its hazy orange atmosphere and land on its surface. Our ship won't be the first human-built device to land on Titan though. The Huygens probe made this place its home back in 2005, when it was dropped off here by the Cassini spacecraft. The Cassini-Huygens mission has taught us so much about this fascinating region of the outer solar system over the last 20 years. Now we want to take you to Titan so you can experience it for yourself. So suit up and strap in. It's nearly time to land on this fascinating landscape of hydrocarbon oceans, and icy mountains. And we'll be joined over our radio comms interface by Alexander Hayes, an assistant professor at Cornell Universty in the Astronomy department. He’s part of the Cassini Mission to Saturn research team, so Titan is basically his second home. We're in good hands! Things to Learn Perspective - how far away from the sun is Titan? What's the story behind the Cassini-Huygens mission? What did scientists expect to find on Titan? Were they right? What does it look and feel like on Titan? What kind of suit will you need to explore Titan? How does sound work on Titan? Why are regions and features on Titan named after places from Lord of the Rings, and Dune? Who decides on these names? Tasks Enjoying the journey so far? We'd love it if you could drop us a wee five-star rating and review on Apple Podcasts, or your podcast app of choice.

Our Small & Fragile Existence | Episode 1

Would you like to go on an audio tour around some of the most fascinating yet deadly places in the universe? Of course you would. Well, consider this inaugural episode of Hostile Worlds to be your invitation and boarding pass. I say boarding pass, because we'd like you to join us on board The Tardigrade. An all-purpose exploration vehicle that can float, fly, dive, or dig through any environment. It's (nearly) time to go and visit all the places you'd die to see, and places you'd die if you saw. In this episode, I'm busy trying to set the scene of the show. On top of that, I need make sure the ship gets built, and hire a small crew so I don't need to do all the talking myself. Things to Learn Perspective - we're going to make you feel really small. What on Earth is a Tardigrade and why is that the name of our ship? Why we're heading to Saturn's moon Titan for our first mission, and why it's such an exciting place. I'd also like you to appreciate the fact that this is a space podcast, and a podcast launch, and we've totally avoided any lazy and cliched puns the whole time.

Magic Islands, Cryovolcanoes, & Electric Snow | Episode 3

Welcome to Titan, the biggest moon of Saturn, and the only known cosmic body other than Earth, that we know for certain has actual lakes and seas on its surface. But that isn’t the only reason that makes this frozen moon such an interesting and fascinating place. On this episode, our crew leave the comfort and warmth of our ship, The Tardigrade, to explore the surface of Titan. Their mission is to report back on the curiosities and mysteries of this hazy extraterrestrial landscape. A landscape which is, on the one hand, very familiar, yet on the other hand, truly alien to us. Things to Learn What does a hydrocarbon ocean look like? What’s so weird about the dunes on Titan? What on Titan is “electric snow” and “electric sand”!? What’s the story behind the “magic islands” in Titan’s seas? And what might they be? What is a cryovolcano, and why might they exist on Titan? Could life feasibly exist way out here? Task Where would you like to see The Tardigrade visit and explore in a future mission, and why? Get in touch and tell us all about it!
