"That is one cool thing about Landsat... people are always finding new applications."

"[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.'"

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

"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."

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

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

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

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

"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."
