Landsat 8 (previously named the Landsat Data Continuity Mission) is a joint NASA/U.S. Geological Survey (USGS) mission and is the eighth satellite in the Landsat series. The observatory consists of the spacecraft bus and its play load of two Earth-observing sensors, the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). OLI and TIRS collect data jointly to provide coincident images of the global and surface including coastal regions, polar ice, islands, and the continental areas. In addition, Landsat 8 follows the same sequence of fixed ground tracks as the Landsat 4, Landsat 5, and Landsat 7 satellites. This allows all the science data from Landsat 8 to be referenced to the same coordinate system, continuing the decades-long data record. The Landsat Program provides repetitive acquisition of high resolution multispectral data of the Earth's surface on a global basis. The data from the Landsat spacecraft constitute the longest record of the Earth's continental surfaces as seen from space. It is a record unmatched in quality, detail, coverage, and value. NASA and the USGS jointly manage the Landsat Program.
