Earth is changing, and these changes can be seen from space. A series of satellites built by #NASA and operated by the U.S. Geological Survey (USGS) have been monitoring and tracking changes across our planet for almost 50 years. Adding to this legacy circling the globe every 99 minutes and collecting images of the #Earth landscapes and coastal regions, #Landsat9 will continue to answer the many questions we have about Earth’s climate change, population growth and even your very own food supply.
