“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.”

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

“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.”

“Work has begun on the next mission, Landsat 9, with launch scheduled for late 2020. Plans for the next generation of Landsat are also underway, with a series of studies leading to a decision on the Landsat 10 and beyond architecture in 2018.”

“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.”

“Landsat is an invaluable resource for developing these high resolution maps. Without the Landsat imagery we would not have the spectral information needed to decompose urban landscapes into Local Climate Zone types. Hence the data is at the heart of the project and it is the most critical piece—without Landsat there is no project.”

“The water resources communities all through the United States, especially in the irrigated areas, are very appreciative that NASA put the thermal imager on Landsat 8 and that future Landsats are guaranteed to include a thermal imager.”

“[Landsat] has transformed our understanding of Earth and allows us to better monitor and respond to changes on our planet.”
