“Landsat sees the earth in a unique way. It takes images of every location in the world to reveal earth’s secrets, from volcanic activity to urban sprawl.”


“When fighting broke out, the [New York Times] graphics team pulled up images from [the] Landsat 8 satellite to look for changes on the ground.”


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


“Landsat has undoubtedly transformed our ability to understand urbanization processes and how cities expand and evolve… the multi-spectrality of Landsat, its relatively high spatial resolution, its revisit period, and especially the long observational record that made millions of scenes publicly available, make Landsat a key asset for the research community.”


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


“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.”


“@USGSLandsat @NASA_Landsat wrote the book on open data, how to do it right, how it creates businesses and benefits economy, and — of course — gifts the world with a 4+ decade *scientific* record of our planet’s changing dynamics.”


“We had to push the spatial resolution because we’re interested in humans.”


“Assessing land cover change, especially the dynamics of smaller water bodies, requires spatial resolution and temporal frequency that are currently only available from the Landsat program. The continuation of the Landsat program will increase the data quantity available for analysis.”


“A new era of open-access satellite data has arrived. In 2008, The U.S. Geological Survey released for free to the public its Landsat archive, which dates back to the 1970s and is the world’s largest collection of Earth imagery.”


“Without Landsat, ‘we would be flying blind. We need those eyes in the sky to complement our ground efforts.'”


“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.”


“There is no satellite record that has the temporal reach of Landsat. While new satellite- and aircraft-based sensors are coming online with sub-meter resolution offering more and more spectral bands, none of them allow the types of temporal investigation that the combined generations of Landsat offer.”


“We had to push the spatial resolution because we’re interested in humans.”


“Once you start playing around with Landsat, it kind of becomes your hammer.”


“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.”


“By analyzing velocity estimates extracted from 30 years of Landsat data, this study highlights the complex, and sometimes counterintuitive, interplay between surface meltwater and ice motion.”


“Assessing land cover change, especially the dynamics of smaller water bodies, requires spatial resolution and temporal frequency that are currently only available from the Landsat program. The continuation of the Landsat program will increase the data quantity available for analysis.”


“Sterling service of over four decades of Earth Observations. No ifs, no buts, just a long-term mission to aid science & society.”


“By combining the 34-year record provided by Landsat [30 m] with climate data, we can now quantify relations between water availability and vegetation dynamics in ways that were not previously possible.”


“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.”


“We would not have been able to complete this research without Landsat’s free and open data policy.”


“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.”

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.
