“Observing the Earth’s land surface from space at 17,000 miles per hour” with Dr. Pete Doucette begins at 11 a.m. at the Historic Homestake Opera House.

You may think you know our planet well, but have you ever wondered how Earth’s land surface changes over time? Dr. Pete Doucette is the acting director for the Earth Resources and Observation Science (EROS) Center in Sioux Falls, South Dakota.

On Neutrino Day, Doucette will demonstrate how Landsat satellites have been imaging the Earth’s land surface from space at speeds of 17,000 miles per hour, and over many years. You’ll hear how scientists use satellite measurements of visible and invisible light, together with machine learning methods, to help track and understand the amazing changes occurring to the land surface across our home planet. 

“The Earth is our home. Neutrino Day is a great opportunity to come and learn about how science is used to understand and protect our home today and for future generations,” said Doucette.
