Landsat 8, launched by NASA in 2013, continues a legacy of Earth observation since 1972. Managed by the US Geological Survey, it has exceeded its mission by providing valuable global data. The satellite's advanced design allows for more sensitive measurements, detecting more wavelengths and collecting unprecedented data. This enables scientists to monitor forests, assess water quality, and track glacier movements. Landsat 8's data is crucial for measuring agricultural productivity and understanding changes in the cryosphere. Despite a design life of five years, it remains operational, with future satellites in development to expand the Landsat archive, available for public use at no cost.
