“Landsat 7 sustained decades of continuity by evolving satellite observations and data products to meet changing priorities and national needs. Its unqualified value to the Nation in science and operational applications helped ensure the future of the long-running Landsat program…”
“If you had one dime to call from a phone booth and you needed imagery, Landsat’s the imagery source to call. Landsat provides the longest-running, well-calibrated and trusted source of information.”
“Consistent, trustworthy, and accessible satellite data make monitoring the rapid changes of Earth’s surface possible.”
“The satellite data from Landsat are one of the most important inputs to the ET models, which use the satellite data to measure patterns in land surface temperature and vegetation extent and condition at the scale of individual fields.”
“It’s hard to overstate the impact of the Landsat program: Landsat data allows scientists to understand land use and land cover change, including processes such as urbanization, deforestation, crop monitoring, monitoring and management of natural disasters (such as floods and wildfires), and more.”
“Landsat’s 30-meter spatial resolution strikes a balance—it’s detailed enough to provide actionable insights for local and regional decision-making, yet broad enough to enable global-scale analyses.”
“Landsat has been a catalyst for innovation in administering water rights. Now we can be much more precise in measuring and monitoring and then administering rights.”
“[W]e estimated the total direct Landsat value to registered Landsat users was $25.63 billion in 2023. However, the economic benefits to direct users are just one part of the total benefit generated by Landsat imagery.”
“Landsat 7 data have been pivotal in documenting environmental changes such as natural disasters, deforestation, and urban growth over its 25 years. Notably capturing significant events like Hurricane Katrina in 2005, the Haiti earthquake in 2010, the Australian bushfires in 2019 – 2020, the dramatic growth of cities worldwide and more through its long-standing mission.”
“Landsat Next… will provide significantly improved data on global environment change, natural resource utilization, and dynamic landscapes; all information needed to inform future policy decisions and to drive groundbreaking advances for multiple scientific disciplines.”
“As cool as the ‘Your Name in Landsat’ tool is, it highlights a very important mission and contribution to society.”
“The Landsat Next 2030 initiative between USGS and Geoscience Australia is nothing short of transformational…This initiative represents a pivotal step towards a more unified future in Earth observation, enabling us to unlock tremendous potential in landscape analytics for societal benefit.”
“There’s a lot of information sitting in those spectral bands that is waiting to be uncovered.”
“[T]o look at long-term changes, you’re going to need Landsat because Landsat is the only thing that’s going back four decades.”
“We’ll then often use imagery when available from Landsat or Sentinel-2, whose higher spatial resolution gives us a better chance of seeing smoke. If we see smoke on the imagery at the same location, then it’s a pretty sure bet it’s an active fire.”
“Every pixel in a Landsat product is a scientific measurement and every pixel has been very carefully calibrated.”
“Landsat Next to me is an incredible mission… I really think of it as a game changer. The measurements provided to the community not only provide continuity with our current 52-year plus archive, but also drive new and emerging applications and science research. It’s very important to the American people and of course to science.”
“First of all, the Landsat project is a joint agency [project] between NASA and the USGS. Really, think of us as one project team. We work very, very closely together.”
“…Landsat products can be used—and are necessary—for quantifying and summarizing water use volumes at spatial scales that are relevant for water resource studies in water-limited regions.”
“The spectrum of observations will be more finely divided with the next Landsat satellites; that will allow for even greater and more precise differentiation of the types of land cover on the surface of Earth.”
“Landsat optically observes Earth’s surface through measurement of reflectivity and temperature in polar ice and oceans, as well as across the Earth, and these are two key geophysical parameters for measuring and modeling surface energy balance.”
“This is really an exciting time for Landsat polar science, a new era so to speak. With Landsat Next on the horizon, the LEAP special request program and its observations of Earth’s polar regions—and the global cryospheric state more broadly—can only be expected to grow in impact and relevance.”
“We’re taking darkness out of the equation. Extending the ability to observe ice and polar ocean changes increases the probability of capturing major glacier calving events, wind-driven surface melting or warming, and coastal ocean ice shelf breakup that can be expected to occur more frequently in the future if the pace of warming does not slow.”
“[H]ope for the future comes from looking at the past. For more than five decades, Landsat satellites, developed by NASA and operated by the United States Geological Survey, have captured a wide range of information about the world’s land and water resources. They provide us access to a rich archive of imagery that shows how we can better manage and capitalize our land, driving sustainable increases in productivity and profitability.”
“While many previous studies have reported ongoing ice shelf thinning around Antarctica since the 1990s, we didn’t previously know that a lot of it started around then.”
“The Landsat program has produced an unmatched record of observational coverage of Earth’s surface extending back to 1972, offering stunning satellite views of landscapes all over the world. This collaboration between NASA and the U.S. Geological Survey (USGS) has also yielded more than five decades of scientific discoveries as Earth’s climate has changed.”
“OpenET is working to make the unseen process of evapotranspiration as easy to track as checking the amount of rainfall in the daily weather forecast.”
“Landsat data has proved invaluable for much of the work we do to try and comprehend how Earth’s cryosphere is responding to a warming planet and to infer what those results mean for our collective future.”
“There is no more powerful tool for tracking land change through time than the Landsat series of satellites.”
“As the impacts of the climate crisis intensify in the United States and across the globe, Landsat satellites are crucial to providing data and imagery to help make science-based decisions on key issues including water use, wildfire impacts, coral reef degradation, glacier and ice-shelf retreat, and tropical deforestation.”
“The USGS Landsat Surface Reflectance products have revolutionized human-scale biophysical studies that require consistent and atmospherically corrected products.”
“Science and technologies, especially satellite imagery, are absolutely essential because people’s livelihoods, natural resources, and biodiversity are connected to each other. Satellite imagery are our eyes in the sky, providing those insights and up-to-date information.”
“The stories that you can tell around the [Landsat] images, along with the images, make something very, very powerful. And you need both to make the kind of impact that we need to make today to help people understand the devastation we’ve caused. But [also] to give them hope that we can turn things around. And that’s what these satellite images show so clearly.”
“The synergistic use of Landsat, GPM [Global Precipitation Measurement], and GFS [Global Forecast System] can help the world become more water-efficient and energy-efficient in growing food, while also becoming more affordable and convenient for farmers.”
“We live on this planet Earth. We all know that we want to leave this planet for our children. We know the importance of sustainability and I think that’s what Landsat’s all about. It’s about helping us manage the planet that we live on for the long-term. And that’s why it’s there and that’s why it continues to be here. And I expect it to be there for the next generation as well.”
“Our mission right now is really a quantum step forward from previous Landsats… I can’t wait to see what comes out of all of these emerging applications and how well it supports the user.”
“Landsat has been historically the gold standard reference for calibration of many different missions across the whole globe. The radiometric quality for Landsat Next will be at least as good as any previous Landsat. So, we will maintain that standard for calibration and referencing for all missions.”
“I have really appreciated being able to use Landsat data as a ‘time machine’ to understand our changing environment.”
“We have so many options with Landsat Next, to add additional information and context to support our wetland managers as well as continuing the historical record of change and variability of our wetlands.”
“It is one of the greatest wetlands management tools that has become available in many years. The wetlands mapping plus WIT outputs are used on a daily basis by a very broad range of stakeholders, from government officers to planners and to those involved in on-ground rehabilitation and management—frankly it’s hard to know how we managed without it.”
“The Landsat data record is absolutely invaluable—wetland managers can start to understand if changes they are seeing take place over months, years or decades.”
“Landsat is the only operational satellite that combines thermal and optical data at the spatial resolution needed to assess water use and water rights, which is often at the level of individual agricultural fields.”
“Landsat is the gold standard calibration reference because the Landsat Program has committed to world-class radiometric and geometric calibration standards.”
“We are very excited to employ integrated Landsat and Sentinel-2 data. The combined observations provide an unprecedented capability and, we expect, an unprecedented record of global land change.”
“Timelapse in Google Earth is possible because of the commitment to open and accessible data through NASA and the United States Geological Survey’s Landsat program (the world’s first and longest-running civilian Earth observation program) and the European Union’s Copernicus program with its Sentinel satellites.”
“We got everything we asked for.”
“[The Landsat MSS sensor] transformed expectations of how we can know the Earth.”
“Landsat’s superpower is time travel… With phenology, vegetation phenology, and drought impacts, the time dimension is extremely important and more frequent data allows for higher accuracy and better characterization of agricultural phenomena.”
“Landsat and agriculture go hand in hand because agriculture is a seasonal phenomenon, and you really need to monitor it closely over time.”
“The Landsat program relative to agriculture monitoring has been profound. The whole idea that Landsat could look at the condition of crops, the acreage of crops, seeing how they evolve, diseases… it just has been tremendously impactful for agriculture.”
“Landsat, with its five-decade record of robust collection, calibration and archiving, and its longstanding service as a global reference to cross-calibrate other missions, improves not only the quality of those systems but the overall quality of the global ‘system of systems’.”
“Understanding how this planet works and helping people make better, informed decisions is really what we’re about in Earth Science.”
“The ability to see what was happening through time through Landsat imagery helped us tremendously… from sea-level, we hadn’t seen the signs of retreat that the Landsat imagery showed us—the diminishing of the glaciers, of the size and mass of the glaciers. It rocked our world. It truly changed the narrative of interpretation in Glacier Bay. The story that we shared with visitors about glaciers in Glacier Bay was transformed by that information.”
The Satellite Stewards of Glacier Bay
“Landsat can see the surface—human settlements, forests, coastal systems. It helps us understand crucial areas of biodiversity on land, crop yields, how to manage our resources, how to protect them.”
“For more than fifty years now, Landsat satellites have helped us learn more about how Earth systems work, how human activities affect those systems, and how we can make better decisions for the future. Landsat 9, the latest joint effort by NASA and USGS, proudly carries on that remarkable record.”
“A half-century archive of Landsat’s Earth observations is a magnificent achievement in the history of science. This fifty-year record gives scientists a consistent baseline that can be used to track climate change and enables them to see changes to the land that might not otherwise be noticed.”
“Our ability to analyze decades of history through the Landsat data record provided a strong backbone to this work.”
“As one of the longest data archives suitable for this purpose, Landsat data allows us to analyze coastal wetland change over time-periods that enable us to monitor long-term directional change in the extent of the world’s coastal ecosystems and distinguish them from natural fluctuations. Our work on tidal flats and global coastal wetland change would not be possible without free access to a long-term, spatially comprehensive dataset such as Landsat.”
“Landsat data are essential for monitoring long-term changes of Earth’s ecosystems.”
“There’s still so much more information to retrieve from Landsat’s 50-year, multispectral data record.”
“If it weren’t for Landsat, we wouldn’t be where we are in terms of understanding our Earth.”
“We wouldn’t be where we are today without Landsat paving the way.”
“Many people have no idea how Earth imagery has improved their daily lives as it has become integrated into modern technologies. Like GPS and weather data, information from Landsat is woven into the fabric of our economy and society.”
“As we continue the work to understanding our planet in the face of climate change, Landsat’s unique data and record of our changing Earth has proven invaluable,”
“Over the past 50 years, eight Landsat satellites have circled the planet, which have helped to save and improve lives and support our economy. NASA will continue to work with USGS to improve access to Landsat’s unprecedented 50-year record and build on the program’s legacy.”
