NASA scientists take to the skies to measure pollution in S. Korea
David Miller and Alexandra Brosius of Penn State University discuss readings shown on a computer screen during a May 30, 2016, flight that was part of a six-week joint Korea-U.S. air quality field study in South Korea. The plane has been transformed into a flying laboratory so some three dozen scientists can measure the heavy pollution over the peninsula. Kim Gamel/Stars and Stripes
