“What should be done with the old bird?”


“The growth of open satellite-image archives such as Landsat is leading to more sophisticated data products.”


“Many of our customers’ work couldn’t be done without Landsat.”


“Landsat is providing better [surface] water data—not just at the state level or nationally, but globally”


“Earth Observation data acquired by the Landsat missions are of immense value to the global community and constitute the world’s longest continuous civilian Earth Observation program.”


“It’s a treasure trove.”


“The 30-year record of the Landsat sensors (i.e. TM, ETM+, and OLI) provides a unique data archive for studying the impacts of climate change on ecosystems worldwide, in our case, coastal marshes.”


“You may have heard me say this before, but I firmly believe there are few topics more fundamental to study than the workings of our planet. The earth sciences aim to unravel how the lithosphere, atmosphere, hydrosphere, and biosphere operate—and how they operate together. It is a science of synthesis. And it’s one that needs to move forward, both because of the great service the earth sciences perform for society and the understanding of world-shaping processes that they advance.”


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


“We have a globally consistent, locally relevant map product that can be used in a variety of applications: estimating emissions from deforestation, modeling biodiversity, assessing protected areas, and studying forest and human health. We plan to move our record forward and backward where Landsat has a sufficiently rich archive of data.”


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


“Moving out on Landsat 9 is a high priority for NASA and USGS as part of a sustainable land imaging program that will serve the nation into the future as the current Landsat program has done for decades.”


“Landsat has really become the gold standard of remote sensing from space. It’s provided an invaluable, indelible record of the recent history of our planet.”


“Landsat offers a globally consistent data set with a short enough revisit time to allow us to consider the percent of time that surface water is present on an annual and seasonal basis, while its 30 meter resolution also enables detection of smaller ponds and rivers, providing greater connectivity.”


“Without Landsat it would be essentially impossible to get good Ground Control Point locations from other sources.”


“In many cases the Landsat archive has provided the only consistent source of information to monitor changes in the surface of the Earth.”


“By analyzing 34 years of [Landsat] data, we estimated that about 56% of the rivers globally are affected by seasonal ice [and] that there is 2.5 percentage points decline of river ice globally during this time.”


“We hope to accelerate innovation in climate research, humanitarian relief, and disaster preparedness efforts around the world by making Landsat data readily available near our flexible computing resources.”


“Landsat 9 replaces the older Landsat 7 and represents a step up in terms of image quality and data volume. Having two state-of-the-art platforms in orbit means more frequent data with excellent image quality.”


“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.”


“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…


“Even though I have a book coming out about the Moon Landing, I’ll say it: Landsat is likely the greatest, most impactful, yet under-appreciated, accomplishment of the entire space age.”

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.
