Dan Cziczo, professor and head of the Department of Earth, Atmospheric, and Planetary Sciences in Purdue’s College of Science, was part of the research team that discovered significant amounts of metals in aerosols in the atmosphere, likely from increasingly frequent launches and returns of spacecraft and satellites. Data was collected more than 11 miles above the planet’s surface using sampling tools hitched to the nose cone of research planes.
