https://abc13.com/nasa-news-virginia-norwood-mother-of-landsat-celebrity-deaths/13051081/Virginia Norwood, a woman who changed the way we see the world, died over the weekend at the age of 96.
Norwood, known as the "Mother of Landsat," according to NASA, was a founding figure in the field of satellite land imaging. She designed and championed a piece of technology that is foundational to how we get images of the earth from space.
The pioneering woman graduated from the Massachusetts Institute of Technology and worked on several innovative programs that changed the world, NASA added.
She developed the Multispectral Scanner, which was key to the development of NASA's longest-running program for getting satellite imagery from space.
The Landsat program is a joint program between NASA and the U.S. Geological Survey.
https://landsat.gsfc.nasa.gov/article/virginia-t-norwood-the-mother-of-landsat/Virginia Norwood, a pioneering aerospace engineer who had a pivotal role in finding safe Apollo landing sites, died at 96. A male colleague once quit rather than work under Ms. Norwood’s leadership. When he asked to return, she turned him down.
She embarked on a user-based design study that captured input from the who’s who of resource managers of the era: Ralph Shay from Purdue University; Arch Park from the Department of Agriculture; meteorologist and pollution expert Morris Tepper; and geologist Bill Fischer, hydrologist David Phoenix, and cartographer Alden Colvocoresses, all from the US Geological Survey (USGS).
She spent time in the field with agronomists as they measured light reflectance, counting photons with field spectrometers to assess plant health and uncover the spectral “signatures” of different crop types. She combed the data from laboratories like those at Purdue University and the Environmental Research Institute of Michigan that were flying multispectral imagers on planes.
“I had to talk to people in all kinds of disciplines that I had no idea about before, so I found it utterly fascinating,” she remembers.
She analyzed their input and put together specifications for what spectral bands a space-based instrument should include, what its revisit time should be, and what users needed in terms of geographic pixel location knowledge, spatial resolution, and spectral measurement accuracy.
“I tried to get an intersection of their needs and make the optimal specifications for the scanner itself which would satisfy the broadest range of them,” Norwood explains.
Virginia T Norwood was a highly respected scientist and a pioneer in the field of remote sensing. She is often referred to as the "Mother of Landsat" due to her significant contributions to the development of the Landsat program.
Virginia T Norwood was one of the key scientists involved in the development and launch of the first Landsat satellite in 1972. She also played a crucial role in the development of the Landsat data processing system, which revolutionized the way we collect and analyze Earth observation data.
Virginia T Norwood's work had a profound impact on the field of remote sensing. Her contributions to the Landsat program paved the way for the use of satellite imagery in various fields, such as agriculture, forestry, and environmental monitoring. Her work also helped to advance our understanding of Earth's natural systems and how they are changing over time.
Virginia T Norwood received numerous awards and recognitions for her groundbreaking work in remote sensing. Some of the most notable ones include the William T. Pecora Award, the National Medal of Technology and Innovation, and the NASA Exceptional Scientific Achievement Medal.
Virginia T Norwood's legacy continues to live on through her groundbreaking work and contributions to the field of remote sensing. Her work has inspired countless scientists and researchers to continue pushing the boundaries of Earth observation and using satellite imagery to better understand our planet. The Landsat program, which she played a crucial role in, is still active today and continues to provide valuable data for scientific research and environmental management.
