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


“Landsat is the oldest continually operated program of its kind: Its satellites have been capturing images of the Earth since the Nixon administration.”


“Work has begun on the next mission, Landsat 9, with launch scheduled for late 2020. Plans for the next generation of Landsat are also underway, with a series of studies leading to a decision on the Landsat 10 and beyond architecture in 2018.”


“There is a sensor in the Landsat satellite which measures the intensity of the reflected radiation back into space. What if we could use satellite imagery from the Landsat program to find fossils?”


“We are looking forward to new exciting data to complement Landsat observations and to collaborative research—especially because ESA followed USGS in its open data policy.”


“Satellite technologies have led to one of the most productive periods in the history of cartography, comparable only to the golden age of mapmaking in the sixteenth and seventeenth centuries.”


“Usage rocketed in 2008, when Landsat made its images free. More than a million images were downloaded in the first year, compared with a previous annual high of 25,000 images sold. More than 20 million images have been downloaded since the archive opened and the rate continues to increase.”


“At Google, we use Landsat data on a daily basis.”


“Landsat provides an unparalleled record of how terrestrial Earth has changed since the early 1970s, closely coinciding with the beginning of rapid environmental change. It provides important historical context for the current state of land cover and land use and provides a reference for identifying abnormal types and rates of change.”


“What makes this [Landsat 8] mission team special is the fervor they brought to task. They were challenged to retain the historic data continuity, yet take advantage of new technology while balancing cost and complexity. Few, if any, missions face such a challenge with such consequences on the line. After more than a decade of dedication, this Team launched a new sensor that was more sensitive and robust than previous sensors, and provided not only data continuity but even more and better d…


“There are more than 800 billion Landsat-derived pixels of land in our imagery. If we printed out just our Landsat-based world map at poster resolution, it would cover two acres.”


“We cannot replace Landsat with Copernicus. In fact the programs complement each other. The world has been benefitting from Landsat data for the past 40 years now. It is really a unique and extremely valuable data source that has provided knowledge and understanding of the planet.”


“With these new [Landsat] data, we can begin to unravel the mechanisms by which the ice flow is speeding up or slowing down in response to changing environmental conditions.”


“NASA’s comprehensive study of Earth has provided much of the underlying understanding of current trends in the planet’s climate – including definitive measurements of rising sea levels, glacier retreat, ice sheet changes and the decline in the volume of the Arctic sea ice cap. Our satellites have provided global, long-term views of plant life on land and in the ocean. And our supercomputing power is allowing us to better understand how all the parts of the Earth system work together and he…


“The long, consistent view of Earth from space provided by Landsat sparks advances in science, enables more efficient natural resources management, and promotes profitable applications of the data in commerce and industry. In step with the National Research Council and other objective reviews, the non-federal Landsat Advisory Group has found that the broad benefits of Landsat far outweigh the cost.”


“If you don’t do the calibration right, you can’t do anything else.”


“Landsat is an invaluable tool for people working in our field of community wildfire safety.”


“The [Landsat-informed] World Settlement Footprint is a great example on how we can mobilize the data revolution for the benefits of all countries and cities, leaving no one behind, which is one of the leitmotifs of the 2030 agenda on sustainable development.”


“Landsat satellite data are the most important source we have about how much deforestation happens each year across the Amazon.”


“We believe this type of continuous mapping of forest metrics at expansive scales would not have been possible without the excellent radiometric characteristics of Landsat 8, particularly the high level of quantization and the outstanding signal-to-noise ratio, which enables fine distinctions that were not previously possible.”


“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.'”


“With the full Landsat record available, we can finally look at really big problems, like the global carbon cycle.”

The NASA/USGS Landsat Program provides the longest continuous space-based record of Earth’s land in existence. Landsat data give us information essential for making informed decisions about Earth’s resources and environment.
