Landsat 7, the latest satellite in a series of earth remote sensing satellites, was launched into orbit on April 15, 1999. Of great importance to science, Landsat 7 gathers remotely sensed images of the land surface (and surrounding coastal regions) across the entire globe; using these images, researchers monitor "important small-scale processes on a global scale, such as the inter- and intra-annual cycles of vegetation growth; deforestation; agricultural land use; erosion and other forms of land degradation; snow accumulation and melt and the associated fresh-water reservoir replenishment; and urbanization." The Landsat 7 site provides general information on the satellite, including how images are taken and examples of satellite images. Additionally, several sections describe data (including acquisition), products (with links to examples of recent satellite images), and other applications.
