Dave is joined by planetary geologist Clive Neal from the University of Notre Dame for a spirited conversation on the past, present and future exploration of The Moon. Clive is an expert on the geologic explorations of the Apollo program and a leading proponent for using the moon as an enabling resource for the long term exploration of the solar system. Clive also weighs in on the recent discovery of abundant water in the lunar crater Clavius.

Dave visits with fellow science communicator Amy Quinton. Amy and co-host Kat Kerlin are the creators of Unfold a science podcast featuring research from the University of California at Davis.

Dave is joined by climate and weather expert Daniel Swain from UCLA's School of the Environment and Sustainability. His weather blog, Weather West has been keeping west coast weather watchers and professional meteorologists engaged for nearly two decades.

Dave talks to the founder and CEO of Generation Genius, Jeff Vinokur. "Dr. Jeff" aka "The Dancing Scientist" has been wowing audiences for the past decade with his signature dance moves coupled with dramatic scientific demonstrations. Vinokur's start up, Generation Genius, produces educational video modules along with support materials for K-8 classrooms and distance learners.

The west's epic wildfire season shows no signs of letting up as one Red Flag Warning follows another and millions of acres burn. Dave talks to three experts from the University of California at Davis. Forest ecology experts Malcolm North and Andrew Latimer weigh in on the state of wildland ecosystems past, present and future as they respond to long-term mismanagement, drought, and a rapidly changing climate.

Dave takes a virtual field trip to one of his childhood haunts -- the Griffith Observatory perched above the Los Angeles Basin in Griffith Park. Our tour guide is the longtime Director, Dr. Edwin C. Krupp. Ed's passion for astronomy education and the venerable observatory, built in 1935 and extensively renovated in the early 2000s, comes through as he takes Dave on a trip through time and space at one of California's most iconic venues.

Unlike the fictional Indiana, there is a real-life Dr. Jones and her name is Lucy. Dave talks to seismologist and disaster preparedness expert Lucy Jones. For decades, Jones has been a major TV outlet fixture whenever a major earthquake strikes in the west, particularly Southern California. Jones was one of the drivers behind the Great California ShakeOut simulation which began in 2008. Designed to prepare the LA area for the inevitable Big One on the San Andreas Fault, the program has been seen

Dave learns about fighting fire with fire in this episode as he talks to CSU Chico Professor of Geography Don Hankins. Dr. Hankins teaches a course called "Pyrogeography" examining the role of fire on both landscapes and the communities that inhabit them. Hankins is a firm believer in the importance of using prescribed burning techniques to control fuel loads and enhance the native ecology of areas throughout California that evolved with fire as a natural element of their ecosystems.
