Quotes to Note

“We have brought it from the brink of death and back to life so many times over the last seven years. It’s just amazing what our flight operations team and our engineers are able to do with that spacecraft. It’s the oldest spacecraft of its type still functioning. We’ve certainly gotten our money’s worth out of it.”

“While Landsat instruments are fundamentally just electro-optical transducers that ingest photons and eject a digital bit stream, this transduction relies upon the state of the art in numerous technologies including optics, precision electromechanics, detectors, advanced materials, cryogenics, and signal processing.”

"Three Decades of Landsat Instruments," PE&RS

“By seeing in electromagnetic increments beyond the normal range of human vision, Landsat revealed whole new worlds hidden within the folds of a familiar world we thought we knew so well.”

Shifting Shores of the Australian Continent Mapped with Landsat

“The analysis enabled by Landsat heat data provides a foundation for planning and problem solving. Without the data, we’re just guessing about what interventions work best to mitigate hot spots… unraveling the complexity of urban heat will ultimately help us build better cities and improve residents’ quality of life.”

“We need to drive towards building sustainable cities and human settlements, and this depends on how well we measure these areas and how well we can predict the growth in all these cities in the future. I believe Earth observation and geospatial technologies give us the tools needed in order for us to grow in this direction.”

“The [Landsat-informed] World Settlement Footprint is a great example on how we can mobilize the data revolution for the benefits of all countries and cities, leaving no one behind, which is one of the leitmotifs of the 2030 agenda on sustainable development.”

“The availability of continuous data streams of high quality and free of charge satellite observations such as the Sentinels of the European Copernicus program and the Landsat missions, in combination with the emergence of automated methods for large data processing and data analytics, and the democratization of computing costs, offer unprecedented opportunities to efficiently monitor the changes and trends in urban development globally.”

Having a carefully calibrated multi-satellite record allows us to ensure that we are recording changes to the Earth, and not simply changes in the instrument response. The more detailed observations from Landsat 8 and Landsat 9 allow these subtle changes to be teased out of the long-term record unambiguously.
