A very special, extended conversation with Johns Hopkins University planetary scientist Sarah Hörst is capped by a tour of her fascinating lab. That’s where Sarah and her team simulate decidedly un-Earthlike atmospheres and more. Emily Lakdawalla has returned from this year’s Lunar and Planetary Science Conference with news from around the solar system. Caffeine! It’s on Saturn’s moon Titan AND in the espresso made on the International Space Station! More about the latter in What’s Up.

Dunes, Walnut Shells, Alien Impostors and Other Worlds: A Visit with Sarah Hörst

Headlines: Inheritance of mitochondrial DNA.  Coffee and Parkinson’s disease. Sending your name and a message to the New Horizons spacecraft.  Winds on Mars.  Water on Asteroids. Feature: Titan (starts at 8:55) The solar system has so many different worlds that come in all shapes and sizes and histories, from boiling hot Mercury and Venus to icy Pluto and the Kuiper belt.  Such extreme alien worlds are exciting, but perhaps the places that catch our imaginations the most are the ones that are more familar – perhaps with the hope of humans one day visiting there and even living there.  So we think of places that have atmospheres and have – or once had – liquid water. But then there are those places that live in what you might call “the uncanny valley” between familiar and alien, and perhaps Saturn’s moon Titan fits into that category, with an atmosphere (but not one that you would want to breathe) and lakes (but not ones you would want to swim in). Our guest today is Titan researcher  Dr. Sarah Hörst, an Assistant Professor in the Department of Earth and Planetary Sciences at Johns Hopkins University, where she also is a member of the Hopkins Extreme Materials Institute. She is a Co-Investigator in the proposed Dragonfly mission to Titan.  You can also follow her on Twitter as @PlanetDr. Hosts: Joel Parker, Chip Grandits, Gretchen Wettstein Producer and Engineer: Joel Parker Executive Producer: Susan Moran Contributor: Beth Bennett Listen to the show here:

Titan Talk with Sarah Hörst

On the 29th episode of Exocast:  Hannah is joined by Professor Sarah Hörst from Johns Hopkins University to talk about her lab and working on haze production for solar system planets and beyond. Hugh discusses the concept of Exomoons following the recent potential discovery. Andrew takes a look at the exoplanet news for the past month, and introduces the new format for the Exocup2018! And Sarah adds the not extra-solar, not planet, Titan to the exocast adopted exoplanet family. Also, did we mention the EXOCUP is back!
