Nearly 10,000 scenes were acquired by the Operational Land Imager (OLI) and/or Thermal Infrared Sensor (TIRS) sensors after launch (February 11, 2013) through April 10, 2013, when the satellite achieved operational orbit (WRS-2). NASA-USGS Landsat 8 Satellite Celebrates First Year of Success February 11, 2014 [image-51]One year ago, on Feb. 11, 2013, NASA launched the Landsat 8 Earth-observing satellite from Vandenberg Air Force Base in California. Since late 2008, when Landsat earth observation images were made available to all users free of charge, nearly 30 million Landsat scenes have been downloaded through the U.S. Geological Survey portal – and the rate of downloads is still increasing. The project is the result of collaboration between NASA and the U.S. Geological Survey (USGS) within the Department of the Interior. Landsat 8 collects it's 1 millionth scene. While all of the bands from previous Landsat missions are still incorporated, there are a couple of new ones, such as the coastal blue band water penetration/aerosol detection and the cirrus cloud band for cloud masking and other applications. The MTL file also contains the thermal constants needed to convert TIRS data to the at-satellite brightness temperature.
