Multispectral Scanner
Earth observing sensor
The Multispectral Scanner (MSS) is one of the Earth's observing sensors introduced in the Landsat program. A Multispectral Scanner was placed aboard each of the first five Landsat satellites.
The scanner was designed at Hughes Aerospace by Virginia Norwood. Her design called for a six band scanner, but the first one launched had only four bands. For her work on the design Norwood is called "The Mother of Landsat."
