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


“In order to produce a rock outcrop map for the entire Antarctic continent, we required a freely available georeferenced multispectral dataset. The dataset needed to cover the high latitudes; be recently acquired; be of a high enough resolution to identify individual outcrops and geomorphological features; and have suitable coverage of the continent. On this basis, the Landsat 8 multispectral satellite data was chosen for analysis as no other platform met these requirements. It would not ha…


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


“I’d go to meetings and people were just jumping up and down because they had discovered another use for the data.”


“When I arrived in Gombe 50-plus years ago, looking up at the stars, it never occurred to me that one day, we’d be relying on remote sensing—satellites circling the globe high above—to help unite communities of people and save Gombe’s chimpanzees. NASA—through its resources and data and funding—is helping us to apply the kinds of innovative solutions needed to address the complex problems people and chimpanzees face today.”


“We’re happy to see that the Agribotix imaging system performs so well when compared to Landsat 8, one of the highest quality land imaging satellite systems…”


“Landsat has been extremely beneficial as it allowed us to frequently evaluate the movement of the shoreline based on data gleaned from one consistent source over the duration of the study period. Further, the continued use of Landsat will allow for ongoing monitoring of the coastline in this region to ensure that potential infrastructural improvements are sustainable based on projections of near-term climate change.”


“The Landsat satellite program has provided images of the Earth’s surface for more than 40 years, and so it is ideal for documenting long-term changes in ecosystems such as giant kelp forests.”


“Landsat is really important because it gives us that time component. We can go back in time and see what an area let’s say a coastal zone or a mangrove forest has been like over time.”


“It’s a fundamental resource for the Australian community. It’s used at local government level, state government level, and national levels. It’s our most important Earth-observing satellite with out a question in my mind.”


“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.”


“The Landsat program doesn’t produce images like the ones of astronauts playing golf on the moon nor geologists scaling an erupting volcano, but it has created one of the most important scientific repositories of data ever made.”


“We are learning more about cool things to do with Landsat at a faster rate than anytime in the past.”


“A 35-year dataset in marine biology is really hard to find… But we need long-term data to understand climate change and how it impacts populations. This was an exponential increase in the amount of information available about kelp forests in Oregon.”


“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…


“Without Landsat’s long record, studies like ours would be impossible to undertake, because we don’t have a time machine to go back to the 1970s and 1980s and see how Turkey’s glaciers were doing then. Using Landsat and commercial satellite data together, we can map glaciers with high accuracy. It’s a powerful combination for studying the Earth from space.”


“Using Landsat images, an epidemiologist can build dynamic prediction models that take into account sudden environmental changes which may increase the risk of disease spread.”


“Landsat enabled us to collect a multi-decadal record of the [river] reaches at almost annual resolution. By extending our record into the past we were able to examine how the reaches changed through time providing us with a truly invaluable dataset.”


“The USGS’s Landsat mission has an incredible 40-year record of the planet’s changing landscape, with virtually every spot imaged every eight days. It’s an incredible scientific asset.”


“To make accurate machine learning models of major crops, we needed decades of satellite imagery from the entire globe. Thanks to Google Earth Engine hosting the entire Landsat archive publicly on Google Cloud, we can focus on algorithms instead of worrying about collecting petabytes of data. Earth observation will continue to improve with every new satellite launch and so will our ability to forecast global food supply.”


“Landsat is the longest civil satellite data collection we have. The USGS opening the archive has created opportunities for instructors like us to integrate students.”


“We did a study… where we were looking at the main drivers of change in mangrove forests on a global scale. And we would not have been able to do that if it wasn’t for Landsat data and the standardized, well-calibrated data sets that come out of Landsat.”


“The Landsat archive enables us to develop products that tackle problems and address issues at a continental scale. For a country the size of Australia, this would simply not be possible without free and open access to the full time-series that the Landsat archive provides.”

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.
