Landsat 8 | Landsat Science
The Landsat 8 satellite payload consists of two science instruments—the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 meters (visible, NIR, SWIR); 100 meters (thermal); and 15 meters (panchromatic).
Landsat 8 Bands | Landsat Science - NASA
Landsat 8 measures different ranges of frequencies along the electromagnetic spectrum – a color, although not necessarily a color visible to the human eye. Each range is called a band, and Landsat 8 has 11 bands.

Sep 27, 2021 · The Landsat program consists of a series of Earth-observing satellite missions jointly managed by NASA and the U.S. Geological Survey (USGS). To date, there have been nine missions, eight of which have been operational.
Landsat 8 Mission Details | Landsat Science - NASA
Landsat 8 (formerly the Landsat Data Continuity Mission, LDCM), a collaboration between NASA and the U.S. Geological Survey, provides moderate-resolution (15 m–100 m, depending on spectral frequency) measurements of the Earth’s terrestrial and polar regions in the visible, near-infrared, short wave infrared, and thermal infrared.
Landsat 9 | Landsat Science - NASA
Landsat 9, launched September 27, 2021, joins Landsat 8 in orbit; the satellite orbits are 8 days out of phase. Landsat 9 replaces Landsat 7 (launched in 1999), taking its place in orbit (8 days out of phase with Landsat 8).

Dec 16, 2016 · “We use Landsat 8 to document glacier velocity patterns on a mountain-range-wide scale. Mapping glacier velocity is facilitated by Landsat’s high radiometric resolution and precise geolocation.”
Operational Land Imager | Landsat Science - NASA
The entire Earth will fall within view once every 16 days due to Landsat 8’s near-polar orbit. OLI’s design is an advancement in Landsat sensor technology and uses an approach demonstrated by the Advanced Land Imager sensor flown on NASA’s experimental EO-1 satellite.

Jan 21, 2013 · The Landsat 8 satellite payload consists of two science instruments—the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). These two sensors provide seasonal coverage of the global landmass at a spatial resolution of 30 meters (visible, NIR, SWIR); 100 meters (thermal); and 15 meters (panchromatic).
Data | Landsat Science - NASA
Landsat data, Harmonized Landsat Sentinel-2 (HLS) data, and Landsat-derived data and science products are publicly accessible and free of charge. These datasets can be viewed and downloaded from a variety of map viewers, data portals, and advanced cloud-computer platforms.
Thermal Infrared Sensor | Landsat Science - NASA
Landsat 8 Handbook The Thermal Infrared Sensor (TIRS) measures land surface temperature in two thermal bands with a new technology that applies quantum physics to detect heat.
