113: Belt and suspenders spacecraft with Julie Webster

Cassini’s spacecraft operations team manager, Julie Webster, stops by the show to reflect on Cassini. We chat about the time Cassini dove through Titan’s atmosphere, how Julie monitored thousands of channels of telemetry at once, and how she’s happy that she doesn’t have to spend her time thinking through worst-case scenarios (or “awfulizing”) now that the spacecraft is no more.

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!
