Landsat 4 and EOSAT Landsat 4 launched on July 16, 1982, and was functional until 1993. In addition to the multispectral scanner (MSS), it carried a more advanced imaging sensor called the ...

Norwood is best known for developing the Multispectral Scanner System that flew on the first Landsat satellite, making her the "Mother of Landsat," according to NASA. Landsat 1, launched in July ...

Here's an example using Texas. Landsat is a decades-long satellite program run by NASA and the U.S. Geological Survey. It captures high-resolution images of Earth’s surface, helping scientists ...

But Landsat’s multispectral scanner doesn’t take photographs. It gathers information. The sensors detect electromagnetic energy across a wide range of wavelengths, from short-wavelength ...

The technique, which uses imagery captured by the Landsat program, works specifically to determine ocean depth, or bathymetry, in shallow, nearshore environments. Landsat, the longest-running ...

Ms. Norwood, a physicist, was the person primarily responsible for designing and championing the scanner that made the program possible. NASA has called her “the mother of Landsat.” ...
