Landsat 9

Recent Imagery

The Landsat Program

This joint NASA/USGS program provides the longest continuous space-based record of Earth’s land in existence. Every day, Landsat satellites provide essential information to help land managers and policy makers make wise decisions about our resources and our environment. + Landsat Case Studies ebook

Landsat 9—Continuing the Legacy
This new four-part video series shares the history of Landsat, how Landsat 9 works, how Landsat…

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

— Dr. Warren Cohen, U.S. Forest Service, Landsat Science Team former member, Apr 28, 2020

"Until recently the National Geospatial-Intelligence Agency has relied on very high spatial resolution imagery to assess environmental conditions that may pose threats to national security. This project has demonstrated the beneficial use of Landsat to assess water quality at a regional scale, which enables a broader understanding of changing environmental conditions."

— Chase Mueller, NASA Ames, Dec 16, 2015

"We knew that ice had been retreating from this region recently but now, thanks to a wealth of freely available satellite data, we know this has been occurring pervasively along the coastline for almost half a century."

— Frazer Christie PhD student, School of GeoSciences, University of Edinburgh, Jun 2, 2016

"Nothing is harder to image than the past. It is imperative that all Landsat observations are archived and made available to users."

— Wulder et al., 2015, Aug 23, 2016

"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."

— Dr. Christine Albano, ecohydrologist at the Desert Research Institute, Dec 13, 2019

“You can acquire data until the cows come home. But if the data isn’t available, you can only go so far. If people can’t rely on data availability and continuity, they won’t build a system to use it. And then the whole puzzle falls apart.”

— Alyssa Whitcraft, program scientist at GEOGLAM, Oct 29, 2015

"The Landsat collection 1 datasets represent a milestone in remote sensing science, with comparatively stable radiometric calibration and atmospheric correction."

— Bruce Cook, NASA Landsat 9 deputy project scientist, Jul 1, 2019

"The <a href="; target="_blank">Deltares Aqua Monitor</a> is the first global-scale tool that shows at 30-m resolution where water is converted to land and vice versa. With assistance from Google Earth Engine, it analyzes satellite imagery from multiple Landsat missions, which observed Earth for more than three decades, on the fly."

— Donchyts et al., Sep 1, 2016

“Tropical deforestation plays a big role in global climate cycles... without the transparency of Landsat satellite data is difficult to put your finger on changing trends.”

— Douglas Morton, NASA Goddard Space Flight Center, Feb 25, 2015

"The future looks really exciting..."

— Curtis Woodcock, on Landsat science and applications, Jul 9, 2015
