Learn how EROS began, what we do, and why it matters to you.  View a model of the Landsat 8 satellite and learn about how Earth-observing satellites work. This satellite imagery from around the world is used to monitor change over time, and you’ll see numerous examples of slow and subtle changes as well as rapid and devastating ones.  We invite you to find out why this data center surrounded by a cornfield is a great place to learn about the changing Earth.
