The large swaths of concrete and asphalt that cover much the urban environment’s surfaces are a major factor in the ongoing rise in temperatures that are making life more uncomfortable — and even unhealthy — in big cities. A team of ASU students, many of them Fulton Schools students, hope to gather valuable new information to help address the problem. They’re building and preparing a small satellite designed to help study the impacts of the urban heat island effect as it flies over several major cities, including Phoenix. A grant from NASA is supporting the CubeSat venture. Aerospace engineering student Sarah Rogers is the project manager.
