Tyler Nordgren is a professor of physics and astronomy at the University of Redlands, but he's also an artist. He's perhaps best known for his work on a series of WPA poster-influenced public service science pieces. He was also part of the team who designed the MarsDials, which were used on Mars to calibrate the cameras mounted on the Spirit and Opportunity Mars rovers.

Dr. Nordgren is a staunch advocate of the dark night sky, and he explains why we should consider it an endangered resource. He also, like our host Dave Schlom, loves the National Parks.

Dave Schlom

Dave Schlom is the longtime host and creator of Blue Dot. From surfing to Voyager in interstellar space, rock guitar to orcas in our imperiled oceans, the topics on Blue Dot are as varied as the host’s interests and connections -- which are pretty limitless! An internationally respected space history journalist, Dave is also deeply fascinated by all aspects of the grand workings of nature’s awesome machinery on scales ranging from galactic to subatomic. And topics take in all aspects of the arts and sciences.
