Spacecraft

spacecraft The Landsat 8 spacecraft was built by Orbital Sciences Corporation. The spacecraft contract was awarded in April 2008. The spacecraft accommodates two government-furnished instruments forming the Landsat 8 Observatory, OLI and TIRS. The spacecraft has a design life of 5 years, but carries sufficient fuel for 10 years of operations.

Operational Land Imager

operation land imagerThe Operational Land Imager (OLI) was built by the Ball Aerospace and Technologies Corporation. The Ball contract was awarded in July 2007. OLI improves on past Landsat sensors using a technical approach demonstrated by a sensor flown on NASA’s experimental EO-1 satellite. OLI is a push-broom sensor with a four-mirror telescope and 12-bit quantization. OLI collects data for visible, near infrared, and short wave infrared spectral bands as well as a panchromatic band. It has a five-year design life.

Thermal Infrared Sensor

thermal infrared sensorThe 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. ++ Important TIRS calibration notice from USGS, April 25, 2017: “Stray light from far out-of-field has affected the Landsat 8 Thermal Infrared Sensor (TIRS) absolute calibration since launch. An algorithm to correct for this issue was developed and implemented into the processing system in February 2017.”
