Quotes to Note

 

"“When the first images appeared, people would talk about the folds in the Appalachian Mountains. There had been textbooks written that described the processes that lead to those formations. For the first time it was possible to observe from great height what people had been talking about for hundreds of years.”

— Dr. Jim Irons, Landsat 8 Project Scientist, "Watching Earth Change," American Scientist, Mar 1, 2014

"The economic and scientific benefits to the United States of Landsat imagery far exceed the investment in the system."

"The value of Landsat data is internationally recognized as indispensable to science, natural resource management, commerce, security, foreign policy, agriculture, and education."

— National Geospatial Advisory Committee, Landsat Advisory Group, Statement on Landsat Data Use and Charges, Sep 18, 2012

"Landsat has given us a critical perspective on our planet over the long term and will continue to help us understand the big picture of Earth and its changes from space. With this view we are better prepared to take action on the ground and be better stewards of our home."

"While Landsat instruments are fundamentally just electro-optical transducers that ingest photons and eject a digital bit stream, this transduction relies upon the state of the art in numerous technologies including optics, precision electromechanics, detectors, advanced materials, cryogenics, and signal processing."

— Aram Mika, "Three Decades of Landsat Instruments," PE&RS, Jul 31, 1997

“By seeing in electromagnetic increments beyond the normal range of human vision, Landsat revealed whole new worlds hidden within the folds of a familiar world we thought we knew so well.”
