Ep. 307: The Pacific Ring of Fire

The Pacific Ring of Fire wraps around the Pacific Ocean, including countries like Japan, Canada, New Zealand and Chile. And the inhabitants within those countries are prone to… oh… killer earthquakes, volcanoes and tsunamis. Let’s chat about the history of this region and the kinds of risks they face.

Ep. 305: The Spacecraft That Wouldn’t Die

Last week we explored the various ways spacecraft can die. But this week, we explore the spacecraft (and the scientists) who never give up, snatching victory from the jaws of defeat. We’ll look at clever solutions to potential spacecraft catastrophes. Download the show [MP3] | Jump to Shownotes | Jump to Transcript (more…)

Ep. 304: Death of a Spacecraft

In the end, everything dies, even plucky space robots. Today we examine the last days of a series of missions. How do spacecraft tend to die, and what did in such heroes as Kepler, Spirit, and Galileo (the missions… not the people). Download the show [MP3] | Jump to Shownotes | Jump to Transcript (more…)

Ep. 257: Viking Orbiters

Spirit, Opportunity and Curiosity get all the news now, but it was NASA’s Viking Missions that gave us our first close up view of the surface of Mars. These twin missions, both made of orbiter and lander set the stage for the exploration of Mars, demonstrating that we could actually reach the surface of Mars, […]

Ep. 221: Geomorphology

When we look around our planet, we see a huge variety in landforms: mountains, valleys, plateaus, and more. Continents rise and fall over the eons, providing geologists with a history of the planet’s evolution. The study of these changes is known as geomorphology, and the lessons we learn here on Earth apply to the other […]

Plate Tectonics

Ep. 142: Plate Tectonics

The surface of the Earth feels solid under your feet, but you’re actually standing on a plate of the Earth’s crust. And that plate is slowly shifting across the surface of the Earth. Over geologic timescales, plate tectonics has totally resurfaced our planet, bringing continents together, and tearing them apart. We know we have plate […]

Ep. 141: Volcanoes, Hot and Cold

You’re familiar with volcanoes, eruptive vents where hot magma escapes the Earth’s interior – sometimes with disastrous effects. But did you know that volcanoes have shaped many of the planets and moons in the Solar System, not just our own Earth? And just in the last few years astronomers have discovered there are cold volcanoes […]
