Marking a critical milestone in modern space observation, NASA and the U.S. Geological Survey (USGS) are officially celebrating the completion of Landsat 9’s five-year design life. Launched into orbit on September 27, 2021, the satellite continues to serve as an indispensable asset for monitoring global climate change, tracking natural resource consumption, and providing high-quality images of environmental shifts. This achievement reinforces the enduring legacy of the broader Landsat program, which has managed the longest continuous space-based record of Earth’s surface for over 54 years, helping scientists make highly informed conservation decisions worldwide.
