105: Tectonic fabric with Dr. Donnellan

Dr. Andrea Donnellan stops by the show to talk about GeoGateway, a website that combines different datasets to help geologists. She explains how rocks move like silly putty, and recounts the time a lone cloud masqueraded as tectonic motion. Bonus music at the end is “Glorious Dawn” by Colorpulse.

98: A place on Earth as dry as Mars with Dr. Azua-Bustos

Dr. Armando Azua-Bustos talks about how he discovered the driest place on Earth— a region in the Atacama Desert not far from where he grew up. He explains how he collects and studies microbial life that live in these extremely dry regions. Learn more about his research here, or visit the webpage of the Centro De Astrobiología.

94: Seven hundred new craters on Mars with Dr. Daubar

Dr. Ingrid Daubar stops by to talk about HiRISE, a camera on a Mars-orbiting spacecraft that takes amazing images of the Martian surface. She explains how she uses these images to search for fresh craters, and how you (yes you!) suggest areas of the planet for this camera to image. (Correction to episode: Mars’ atmosphere is 0.6% that ofEarth, not 6%). HiWish public suggestion page!

91: Tectonic hazard on Phobos with Dr. Curren

Dr. Ivy Curren talks about Mars’ moon Phobos, and how grooves on its surface indicate that the interior may be fractured. This small, mysterious moon is covered in faults, making it a dicey place for future missions to land. Enhanced-color image of Phobos, taken by the Mars Reconnaissance Orbiter.

Bonus episode: I wrote a book!

As part of the 2016 TED Fellows class, I got to meet cool people and I got to talk about asteroids. My TED talk is now online (watch it here!) and the companion book, “Asteroid Hunters”, by me, is now available in the US, UK, Canada, Australia, and India. There’s also e-book and audiobook versions. This bonus episode contains an excerpt from “Asteroid Hunters”. “Asteroid Hunters"  is available at Amazon, Barnes & Noble, IndieBound, and as an iBook. An audiobook version will also be available.

87: Visions of interstellar travel with Dr. Hurt

Dr. Robert Hurt returns to the show to talk about artistic depictions of interstellar travel. We discuss the images of the seven-planet TRAPPIST-1 system he and Tim Pyle created— images that graced the cover of Nature and the front page of the New York Times. We also talk about Star Trek: The Next Generation, and what that TV show got right (and wrong) about the visuals of cruising through outer space.
