A Half-Century of Landsat: 50 Years, 50 Stories
In the 50 years since the launch of Landsat 1, scientists, resource managers, mapmakers, communicators and others have relied on images from the satellite series.
To mark the anniversary of this record-breaking mission in 2022, we’re asking 50 Landsat users to tell us a bit about an image that is significant to them or their work.
