About Landsat-8

Landsat-8 was launched on 11 February 2013 from Vandenberg Air Force Base, California on an Atlas-V rocket. The satellite is part of the long-running Landsat programme led by USGS and NASA and carries the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS).

Landsat-8 is part of ESA's Third Party Missions Programme, in which ESA has an agreement to distribute data products from the mission.

Landsat-8 Objectives

Landsat-8 consists of three key mission and science objectives:

collect and archive medium resolution multispectral image data affording seasonal coverage of the global land mass
ensure that Landsat-8 data are sufficiently consistent with data from the earlier Landsat missions in terms of acquisition geometry, calibration, coverage characteristics, spectral characteristics, output product quality, and data availability
ensure products are available to download within three hours

Landsat-8 Instruments

The Operational Land Imager (OLI) provides two new spectral bands in respect to the Landsat-7 ETM+ instrument, one tailored especially for detecting cirrus clouds (band 9, new Near Infra-Red (NIR) band) and the other for coastal zone observations (band 1, new deep blue visible channel). It measures in the visible, NIR, and Shortwave Infra-Red (SWIR) portions of the electromagnetic spectrum and offers 15 metre panchromatic, and 30 metre multi-spectral spatial resolution.

The Thermal Infrared Sensor (TIRS) was added to the Landsat-8 payload to continue thermal imaging and to support emerging applications such as evapotranspiration rate measurements for water management. TIRS was built by NASA Goddard Space Flight Center, and it has a three-year design life. The 100 m TIRS data is registered to the OLI data to create radiometrically, geometrically, and terrain-corrected 12-bit Landsat-8 data products.
