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. USS Deimos (AK-78) Damaged by torpedo, 23 June 1943, then abandoned and scuttled south of Makira island.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).

USS Aludra (AK-72) Lost in action from Japanese torpedo on 23 June 1943 south of Makira island.

The ships were propelled by a reciprocating steam engine using a single screw with a power of 2,500 hp (1,864 kW) shaft. Its 65 hulls were among the largest US Navy cargo ship classes. The class was named for the lead ship of its type, USS Crater (AK-70), with most ships in the class being named for astronomical bodies. The designation 'EC2-S-C1': 'EC' for Emergency Cargo, '2' for a ship between 400 and 450 ft (120 and 140 m) long ( Load Waterline Length), 'S' for steam engines, and 'C1' for design C1. The Crater-class cargo ship were converted EC2-S-C1 type, Liberty cargo ships, constructed by the United States Maritime Commission (USMC) for use by the US Navy during World War II.
