This is the second part of our tribute to Apollo astronaut Alan Bean. Alan was the fourth man to walk on the Moon during the Apollo 12 mission in November of 1969 four month's after Neil Armstrong's "One small step for man..." Bean was a talented and prolific painter who was also extraordinarily kind and generous as one of NASA's legendary Apollo era astronauts. We are joined by his good friend and colleague Rusty Schweickart who was one of the first astronauts to fly the lunar module on the Apollo 9 test flight along with commander Jim McDivitt. in the spring of 1969. Then Dave talks to his friend Andrew Chaikin, author of A Man on The Moon which was the basis for the Tom Hank's produced mini series on HBO, From The Earth to The Moon. Chaikin met Bean when he was a 12 year old visiting the Kennedy Space Center in Florida and later in life interviewed the astronaut extensively for his book, eventually becoming longtime friends with the astronaut. Audio highlights from the surface of the Moon and the number one pop hit from 1969 also appear on the conclusion of this special two part tribute to an American icon and hero.

In this first installment of a two part look at the life and career of Apollo 12 astronaut Alan Bean we hear from two very special astronaut friends. Alan Bean devoted his life to creating masterful oil paintings depicting many aspects of the Apollo Moon landings. Bean passed away at age 86 on May 26, 2018. We talk to his longtime friend, fellow Apollo astronaut Walt Cunningham who flew the very first test of the Apollo Command and Service module in Earth orbit -- Apollo 7. Then we talk to a current member of the NASA astronaut corps, Karen Nyberg, who was befriended by Bean and shared his love of art. Join us as we celebrate the fourth man to set foot on the Moon, Alan Bean.

The Sacramento River flows from its headwaters above Shasta Dam to the Pacific Ocean through the Delta and out the Golden Gate. It is one of the most diverse and productive fisheries in the world. In this episode we examine the anadromous fishery in particular. Anadromous fish are those that spawn in fresh water but spend most of their lives in the ocean like the imperiled Chinook salmon. But we also check out other species of game fish that live in the river like green sturgeon, striped bass and rainbow trout.

  

For the 100th episode of Blue Dot we go volcanic! Dave interviews Erik Klemetti, Professor of Geosciences at Denison University in Ohio. Klemetti is an expert volcanologist who writes about volcanoes for the Discover Magazine blog Rocky Planet. We'll talk about the ongoing and unfolding saga of the Kilauea Volcano's eruptions on the big island of Hawaii. In the second half of the show, we visit with three California State University Chico students who are doing volcanology research as undergraduate students under the guidance of Professor of Geosciences at CSU Chico, Rachel Teasdale. Two of the students, Amy Robson and Angie Rodriguez, are researching the hydrothermal system at Lassen Volcanic National Park and Evan Davis is modeling a lava flow emplacement on Mars. Dave also talks to their mentor about the value of having undergraduate students do high level scientific research projects.

Dave talks to Alan Stern and David Grinspoon, coauthors of Chasing Pluto: Inside The Epic First Mission to Pluto. When Voyager 2 flew by Neptune in 1989, it closed out the golden age of solar system exploration. But it left one unexplored body: Pluto. Stern was part of a group of scientists known as "The Pluto Underground." For years the proposed, lobbied and planned for a robotic mission to what was then, "the ninth planet." The mission that would be eventually called New Horizons went through decades of starts and stops. The story of how this mission ultimately succeeded in July 2015 is a triumphant tale of perseverence.

In this episode Dave visits with Adam Weymouth, author of the new book Kings of The Yukon. In it, he describes taking an epic trip down the length of the Yukon River in a canoe. His purpose is to learn about the longest Chinook or "King" salmon run in the world. As Adam leaves the spawning grounds at the headwaters, the salmon are entering the mouth of the river from the Bering Sea 2000 miles away. Somewhere along the way, the powerful swimmers and the human paddler will meet. As he journeys through Canada and Alaska, Weymouth learns more about both the imperiled salmon and the people who depend upon the salmon for their livelihoods and sustenance. The arcane world of fishing regulations from both the Unites States in Canada often conflicts with the ancient practices of the native people as well as the commercial fisherman profiled in the story. Add in the impacts of environmental degradation and what ensues is a gripping story about one of the last great salmon runs on the planet.

In this episode we talk defense. Planetary defense. From one of the worst of all possible natural diasters, an asteroid impact. Dave talks to Lindley Johnson, NASA's "Planetary Defense Officer" from HQ in Washington, Paul Chodas (an expert on calculating asteroid orbits) and Physicist Megan Bruck Syal from the Lawrence Livermore Laboratory in Pasadena. Johnson and Syal are involved in HAMMER ( Hypervelocity Asteroid Mitigation Mission for Emergency Response), a mission designed to actually deflect an asteroid on a collision course with Earth. One thing that all of our guests mentioned: "This isn't like the movie Armageddon" and while we get that, we also felt the need for a little Aerosmith in the show, and you don't want to miss a thing...so listen and enjoy while contemplating the worst of all possible natural calamities.

In this episode of Blue Dot, Dave talks to Jennifer Strauss from the UC Berkeley Seismology Lab and Ken Hudnut from the United States Geological Survey. Both are deeply involved in the April 18, 2018 roll out of the "Haywired Scenario" a scientifically accurate modeling of a Magnitude 6.8 earthquake on the Hayward Fault. Our conversation revolves around the new technology called Shake Alert. Using seismic monitoring all over the state (especially in quake prone areas such as the Bay area and Southern California), scientists have developed a system to use the early arrival seismic waves, p-waves, to alert us to the imminent shaking that will follow in a matter of seconds. The early warning system can be used on computers and smart phones to let us know how long we have to brace for the hard shaking of a major earthquake. The system will also be used by transportation systems like BART and utility systems like PG&E to best safeguard our infrastructure when the next "Big One" inevitably hits somewhere in California.

Big Wave Dave talks surfing! Featuring a conversation between San Francisco Chronicle sportswriter Bruce Jenkins and retired NASA Oceanographer Bill Patzert, we dive deep under the swells of the world of big waves with an emphasis on Mavericks -- the biggest surf wave on the west coast located in Half Moon Bay. The conversation wraps up reminiscing about Bruce Brown's The Endless Summer and a campaign for surfer license plates as a tribute to the classic film. Mark Sponsler rides big waves like Mavericks and has a website called Stormsurf that forecasts wave conditions for surfers -- he shares his insights on waves -- what makes the perfect surfing wave? We also talk to Surfer Magazine staff photographer Frank Quirarte who takes his camera into the big break at Mavericks on a personal water craft and rescues surfers trapped in the cauldron of whitewater. Finally, a bonus segment listening to surf guitar and surf music with music historian and guitar collector John Biscuti.

On this episode Dave is joined by co-host Kate Fullam as they interview Florence Williams, author of The Nature Fix: How Nature makes us Happier, Healthier and more Creative. The second half of the show features an in depth look at Naturebridge at Yosemite, a program that connects young people to nature on its grandest stage. Dave talks to Kristina Rylands, former Naturebridge participant who is now the head of the program. Nolan Ford visits with Ana Bachman from the McConnell Foundation, which funds high school students from Northern California to attend Naturebridge. Finally, Dave visits with a former student, Nicole Curiel, who attended the Yosemite program in 2016.
