Dave visits with birder and wildlife photographer Dudley Edmondson, author of Black and Brown Faces in America's Wild Faces and outdoor educator/activist Lynnea Atlas-Ingebretson about the challenges and rewards that come with equal access to America's public wildlands and green spaces.

When Dave heard of the passing of one of his personal heroes, Glynn Lunney, he got on the phone to retired NASA Flight Director Gerry Griffin and they put together this special tribute episode for our Apollo@50 series. Glynn Lunney was the fourth NASA Flight Director and was integral to the space program's pioneering Mercury, Gemini and Apollo Projects. He passed away due to a bout with cancer on May 19, 2021.

Dave visits with James Zimring, author of the new book What Science is and How it Really Works. In a wide-ranging conversation that covers everything from the methodology of science, news flash, there really isn't a "Scientific Method" like the version you saw in your high school biology textbook, to some of the most important social issues of our day like the anti-vaccination movement and climate change science denial.

If there is one most contentious issue in the history of California, it is probably water. From the Owens Valley water wars from the early 20th century that were chronicled in part by the film Chinatown, to the modern era of trying to strike a balance between wildlife, fisheries and agriculture as well as urban water use, water is crucial to all stake holders.

Dave talks to NASA's Jason Derleth, the executive in charge of the NASA Innovative Advanced Concepts Program about some future proposals that are being funded that may sound like science fiction but many are likely to revolutionize the future of space exploration. From magnetic levitation tracks on the Moon to miniature robotic submarines to explore the oceans of Europa -- it's science and technology literally at the cutting edge.

Dave talks to polar climate expert Jennifer Francis about the hows and whys of the north polar region's dramatic warming is affecting weather here at temperate latitudes.

Dave takes a deep dive into the science of black holes, which were the basis of the 2020 Nobel Prize in Physics which went to Roger Penrose, Reinhard Genzel and Andrea Ghez. Denver Museum of Nature and Science Curator of Space Science joins us to talk about the Nobel Prize and the basic physics behind our understanding of black holes, which are the ultimate warping of space-time.

Dave investigates two very different but interrelated topics: the deep freeze that sent the power grid in Texas into near collapse and how our cities are disproportionately hot in summer due to the urban heat island effect.
