The instruments on Landsat 9 are improved copies of those on Landsat 8.3. Approximate scene size is 170 km north-south by 183 km east-west (106 mi by 114 mi). Thermal bands 10 and 11 are useful in providing more accurate surface temperatures and are collected at 100 meters. The resolution for Band 8 (panchromatic) is 15 meters. New band 9 is useful for cirrus cloud detection. New band 1 (ultra-blue) is useful for coastal and aerosol studies. Landsat 8 Operational Land Imager (OLI) and Thermal Infrared Sensor (TIRS) images consist of nine spectral bands with a spatial resolution of 30 meters for Bands 1 to 7 and 9. Landsat 7 Enhanced Thematic Mapper Plus (ETM+) Landsat Specific band designations differ from Landsat 1-3 to Landsat 4-5. Approximate scene size is 170 km north-south by 185 km east-west (106 mi by 115 mi).

Landsat 1-5 Multispectral Scanner (MSS) images consist of four spectral bands with 60 meter spatial resolution. The instruments on Landsat 9 were designed as improved copies of the Landsat 8 sensors.

While the earlier satellites carried just one sensor, Landsat 8 acquires data in 11 bands from two separate sensors: the Operational Land Imager (OLI) and the Thermal Infrared Sensor (TIRS). A panchromatic band was added to Landsat 7’s Enhanced Thematic Mapper Plus (ETM+) sensor. The Multispectral Scanner (MSS) carried on Landsat 1,2,3,4 and 5 collected data in four ranges (bands) the Thematic Mapper (TM) sensor on Landsat 4 and Landsat 5 included those found on earlier satellites and also introduced a thermal and a shortwave infrared band. The sensors aboard each of the Landsat satellites were designed to acquire data in different ranges of frequencies along the electromagnetic spectrum ( View Bandpass Wavelengths for all Landsat Sensors).
