Episode 349: Restoring Darkness #49 - Light Pollution Cannot Be Measured…Yet

As you’ve heard on this podcast before, existing satellites are incapable of detecting the blue light of LED’s and thus produce incomplete imagery of light pollution. Ken explains to Michael how he and his colleagues are sending balloons almost 30 kilometers into the sky and beginning to map light pollution in a very unique way. Ken Walczak is the Senior Manager of Far Horizons at the Adler Planetarium in Chicago - a hands-on science, engineering and research program for students, volunteers and the public. He is a board member of the International Dark-Sky Association and an associate member of the IES.
