Landsat 8 carries two push-broom instruments: the Operational Land Imager (OLI), and the Thermal Infrared Sensor (TIRS).
The Landsat Program is a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey.
National Land Imaging (NLI) was an interagency effort (begun in 2006) to develop a long-term plan to achieve technical, financial, and managerial stability for operational land imaging.

For many locations outside the U.S., there may be scenes that were collected by the sensor but the data is not archived or distributed by the USGS.
