Landsat: 40 Years of Observations Reveal a Changing Planet and Society


This photograph of the southwestern United States, taken in November 1966 during the Gemini XII mission, was among those that inspired the Landsat program. Click on image to enlarge.

Since 1972, Landsat has collected more than 3 million images that describe two generations of human imprints on Earth and the planet’s effects on humanity.

The Landsat archives tell an unparalleled story of the planet’s land surfaces, and they are a practical, thought-provoking reservoir of things we need to watch for and to be warned of. The imagery tells a story rich in information that can help us better find ways to peacefully and prosperously accommodate 7 billion people on one small planet.
