The U.S. Geological Survey (USGS) has made it possible for you to watch as swaths of data from the Landsat 5 and Landsat 7 satellites are collected and downloaded to the USGS Center for Earth Resources Observation and Science (EROS) in Sioux Falls, SD.
USGS EarthNow! displays data received from the Landsat 5 and Landsat 7 satellites as they pass over the United States. When a Landsat satellite passes within range of the ground station at the USGS EROS center, image data are downlinked and displayed in near-real time. When Landsat 5 and 7 are not in range, the most recent pass is displayed.
