The Multi Spectral Scanner (MSS) instrument was carried aboard the Landsat 1 to 5 missions between 1972 and 2013. Global MSS acquisitions ended in 1999, even though Landsat 4 and 5 were still active.
MSS was built by SBRC (Santa Barbara Research Center) of Hughes Aircraft Company in Goleta, CA.
The objective of MSS was to provide repetitive daytime acquisition of high-resolution, multispectral data of the Earth's surface on a global basis and to demonstrate that remote sensing from space is a feasible and practical approach to efficient management of the Earth's resources.
The Multi Spectral Scanner (MSS) on the Landsat 1 to 5 missions was an opto-mechanical scanning instrument (whiskbroom technique, unidirectional operation) consisting of a double reflector-type telescope, scanning mirror, filters, detectors, and associated electronics. The MSS instrument had a spatial resolution of approximately 79 metres with four bands ranging from the visible blue to the Near Infra-Red (NIR).
|Swath Width||185 km|
|Cross-track Resolution||56 m|
|Along-track Resolution||79 m|
Band 4: Visible green (0.5 to 0.6 µm)
Band 5: Visible red (0.6 to 0.7 µm)
Band 6: Near-Infrared (0.7 to 0.8 µm)
Band 7: Near-Infrared (0.8 to 1.1 µm)
The thermal band 8, 10.4-12.6 µm, was also part of the Landsat 3 MSS, however, the channel failed shortly after launch
