OLIOperationalMeasures surface radiance, land cover state, and change (e.g., vegetation type). Used as multi-purpose imagery for land applications.n/a
OLI-2OperationalMeasures surface radiance, land cover state, and change (e.g., vegetation type). Used as multi-purpose imagery for land applications.n/a
TIRSOperationalMeasures longwave thermal infrared surface emittance, land cover state, and change. Used as multipurpose imagery for land applications.n/a
TIRS-2OperationalMeasures longwave thermal infrared surface emittance, land cover state, and change. Used as multipurpose imagery for land applications. TIRS-2 will adhere to the Landsat 8 TIRS instrument performance specifications but will be built to NASA Class-B instrument standards (including a 5-year design life).n/a

PLATiNO TIRNo longer consideredDeveloped by Leonardo and SITAEL, PLATiNO-2 TIR will acquire images that will be used to provide valuable services for territories control and protection such as monitoring waters, glaciers, pollutants, state of crops and vegetation, energy consumption in urban areas. PLATiNO-2 is also equipped with the magnetically shielded HT 100, an improved version of SITAEL electric thruster, making PLATiNO-2 one of the first missions in the world to observe the Earth in the Thermal Infrared from a very lown/a
