“Landsat 5 is kind of like the (Energizer) bunny — it just keeps running and running.”

“Landsat optically observes Earth’s surface through measurement of reflectivity and temperature in polar ice and oceans, as well as across the Earth, and these are two key geophysical parameters for measuring and modeling surface energy balance.”

“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…

“We have recognized for the first time that we’re not just going to do one more, then stop, but that Landsat is actually a long-term monitoring activity, like the weather satellites, that should go on in perpetuity.”

“Landsat has given us a critical perspective on our planet over the long term and will continue to help us understand the big picture of Earth and its changes from space. With this view we are better prepared to take action on the ground and be better stewards of our home.”

“The Landsat thermal sensor can provide critical information on Nevada’s water resources because it provides the only efficient and accurate way to map how much and where water is being consumed.”

“Timelapse in Google Earth simply wouldn’t have been possible without NASA and the United States Geological Survey’s Landsat program, the world’s first (and longest-running) civilian Earth observation program, and the European Union’s Copernicus program with its Sentinel satellites.”

“Whether it’s since 1985 or 2000, we see this greening of the Arctic evident in the Landsat record.”
