End of an Era: Landsat 7 Decommissioned After 25 Years of Earth Observation

After 25 years of capturing Earth's changing landscape, the Landsat 7 satellite received its final transmission from the U.S. Geological Survey and was officially decommissioned June 4, closing a remarkable chapter in space-based observation.

While Landsat 7’s long watch over Earth comes to an end, Landsat 8, launched in 2013, and Landsat 9, launched in 2020, continue to work together to create a complete snapshot of Earth every eight days. Their successor—Landsat Next—is currently planned to launch in the early 2030s and provide even greater coverage and detail.

Launched in 1999 as a joint mission of the USGS and NASA, Landsat 7 significantly enhanced Earth observations and provided a key part of the Landsat program’s five decade-plus record of imaging the planet’s surface. The satellite's imagery will remain archived at the USGS Earth Resources Observation and Science Center, continuing to support scientific discovery and decision-making for the future.

“The Landsat satellites have delivered over 50 years of extraordinary science data, economic value and national security benefits by informing decisions in every sector of the economy—from monitoring drought in the West to guiding disaster recovery,” said Sarah Ryker, USGS Acting Director. “For 25 of those years, Landsat 7’s data helped farmers, land managers, city planners, and scientists, as well as communities around the world better understand and manage land, water, and other natural resources.”

Landsat 7 achieved many milestones over its 25 years of operation and was the first Landsat to downlink data to the newly established USGS ground station in Sioux Falls, South Dakota. It was also the first Landsat satellite to be fully operated 24/7 by the USGS after being launched by NASA.
