Dave Schlom

Host, Blue Dot

Dave Schlom has taught the physical sciences at Corning Union High School since 1991. A lifelong amateur astronomer and astronomy educator, he has a passion for both the earth and the space sciences, which are the principal areas of focus for guests on Blue Dot. He started doing radio interviews on space and astronomy topics for local stations like KFM and KPAY in the 1980s and into the 90s, where he was a popular go-to guest for local radio personalities. He is also an expert on the history and geology of Lassen Volcanic National Park, where he has served as a volunteer for decades. Dave enjoys a quiet life at home with his partner in life, Cheryl, and their two dogs, Elvis and Pearl, at their Red Bluff residence.


Jessica Neu studies Earth's atmosphere for NASA's Jet Propulsion Laboratory. She tells Dave Schlom about the impact of ozone in the lower parts of the atmosphere, and about what major polluting countries like China and the U.S. are doing to combat — and add to — the problem. 

The dwarf planet Ceres is the largest object in the Asteroid Belt. NASA's Dawn spacecraft is using its special ion engine to stay in orbit around Ceres. Dave Schlom talks with mission director and chief engineer Mark Rayman about the craft and what wonderful new science it will send back next.

KRCR Meteorologist Rob Elvington talks about how hot it's been this year and goes into the likelihood of El Niño bringing the North State some wet weather this upcoming rainy season. 

The Blue Dot Report: Pluto Special

On July 14, the space probe New Horizons went on its closest approach of Pluto. It's already sent back iconic images of the distant world, but that's just the tip of the iceberg as far as the deluge of data still to come. Host Dave Schlom talks with New Horizons team lead Alan Stern and co-investigator Joel Parker about the mission. He also checks in with a Pluto Pal, who has the same launch date as New Horizons — 1/19/06. 

Derek Muller is the creator of the popular science YouTube channel Veritasium. He's also host of a new documentary called "Uranium: Twisting the Dragon's Tale," due out in the U.S. July 28th on PBS.

The New Horizons spacecraft is finally closing in on Pluto, and we're going to be able to feast our eyes on high-resolution photos of the dwarf planet and its largest moon Charon. Joel Parker is with the project, and talk with Dave Schlom about these exciting new images.

United State Geological Survey scientist Mike Clynn talks with Dave Schlom about what exactly happened when Lassen Peak erupted 100 years ago. 

Astrophysicists use the intrinsic brightness of certain kinds of stars to determine the age of the universe. Dave Schlom talks with Don Neil, a scientific analyst with Galaxy Evolution Explorer, about the rich data that project has yielded — especially regarding these benchmark stars.

Methane: Global Warmer

Apr 16, 2015

Riley Duren, an engineer at NASA's Jet Propulsion Lab, works for the Megacities Carbon Project. The project looks at the large metropolitan areas of the world, and how their emissions contribute to global climate change. In this episode, Duren talks with host Dave Schlom about how methane fits into the greenhouse gas picture.  

Why is Antarctica's Totten Glacier is melting? What does it mean for earth science and what does it mean for our changing climate? Dave Schlom talks with Dustin Schroeder from NASA's Jet Propulsion Laboratory.
