173: Last alert system with Dr. Denneau
Dr. Larry Denneau talks about the Asteroid Terrestrial-impact Last Alert System, or ATLAS. He talks about how asteroid detection is a data processing problem. Every night ATLAS handles about a quarter terabyte of data. He describes how they find a few asteroids among a billion other sources, and tells us about a unique discovery by the program.

172: The whole world to a microbe with Prof. Levy
Prof Joe Levy talks about his research in the dry valleys of Antarctica. These valleys are dry, irradiated, salty, and cold, which makes them similar to parts of Mars. He explains why planetary scientists get excited about naturally occurring perchlorate. He also describes the changes he's witnessed over several field seasons. This episode was recorded in February 2020, before social distancing measures were recommended.
