Quotes to Note


"[Landsat] became freely available in 2008 and I think that that completely changed how we are able to use this type of data for decision making."

"This global census can help identify other lakes in need of monitoring or remediation, Dr. Shugar said. 'We hope that it allows governments to see where the hot spots might be for glacial lakes growing in the future.'"

— Dan Shugar, glaciologist at the University of Calgary, speaking of his Landsat-based glacial lake inventory, New York Times, Oct 2, 2020

"Whether it’s since 1985 or 2000, we see this greening of the Arctic evident in the Landsat record."

— Logan Berner, a global change ecologist, Northern Arizona University, Flagstaff, Warming Temperatures are Driving Arctic Greening; NASA, Sep 23, 2020

"LANDFIRE is the only complete, nationally consistent collection of spatial resource datasets with an ecological foundation."

"The success of a mission, and the societal benefits it creates, relies on many factors, including design, manufacture, launch, and operation of the sensor. However, it also includes data acquisition, accessibility, availability, and continuity, all of which are embodied by the Landsat program."

"There is no other asset in the sky that can show us what Landsat does in terms of the effect of this eruption and also the effect of recovery following the eruption."

— Dr. Sean Healy, U.S. Forest Service, 40 Years After Mount St. Helens’ Eruption, 40 Years of Forest Recovery, May 18, 2020

"I can't imagine what it would be like to describe what this volcano did without having a time series of Landsat."

— Dr. Sean Healy, U.S. Forest Service, 40 Years After Mount St. Helens’ Eruption, 40 Years of Forest Recovery, May 18, 2020

"Land cover is fundamental for a plethora of applications. Approaches using #Landsat time series have been transformative."

— Dr. Joanne C. White, Research Scientist, Canadian Forest Service, via Twitter, May 6, 2020

“Thanks to satellites and to science, we now know much more about Earth than we did on the first Earth Day fifty years ago.”

— Dr. Michael Freilich, former director of NASA’s Earth Science division, #EarthDayAtHome with Earth Scientist Michael Freilich (video), Apr 30, 2020

“I don’t think there’s any question about how important and how valuable MSS is.”

— Dr. Warren Cohen, U.S. Forest Service, Landsat Science Team former member, Making Use of MSS: The Effort to Fold the Earliest Data into the Landsat Record, USGS EROS, Apr 28, 2020

"Because Landsat's been operating for so long—thermal imaging has been enabled since the 1980s—we can study how patterns in water use have changed over the landscape over long periods of time as the climate has changed and as land use patterns have changed. So Landsat has been really a critical sensor for our work."

— Dr. Martha Anderson, USDA Researchers and Landsat Science Team Member, Landsat Gives Epidemiologists Key Insights, Apr 22, 2020

“The archive is just going to continue to yield good information, good science, better management, reduced costs... The biggest contribution of Landsat will be that archive.”

— Dr. John Schott, professor at the Rochester Institute of Technology, Free, Open Landsat Data Unleashed the Power of Remote Sensing a Decade Ago, USGS EROS, Apr 17, 2020
