Eyes on Earth

Far beyond the atmosphere of Earth, at orbits ranging from 290 to over 35,400 km (180 to over 22,000 miles) above sea level, circle the satellites of the Earth Observing System (EOS), NASA’s primary satellite mission. This small group of human-made scientific observers is constantly scanning our planet–tracking weather, monitoring pollution, creating maps, and gathering information that helps scientists predict storms, monitor forest fires, and study the holes in the ozone layer.
Eyes on Earth is a highly interactive science exhibition produced and developed by the Oregon Museum of Science and Industry (OMSI) that focuses on the EOS and examines how satellite observations are made and what we can learn about the Earth using space and satellite technology
