“It is undeniable that having access to long-term satellite data has allowed ecologists and environmental managers to increase their understanding of the natural world, to make predictions about how this world might transform and to design efficient mitigation and adaptation strategies in the face of global environmental change.”

“Landsat’s work is epic in scale. In 43 years, it has amassed over a petabyte of data, with over 4 million scenes and counting.”

“The Landsat satellites have provided an unprecedented volume of high quality medium-resolution imagery spanning more than 30 years. Without this record it would be exceedingly difficult to place presently observed changes in ice discharge into a longer-term context.”

“I can’t imagine what it would be like to describe what this volcano did without having a time series of Landsat.”

“You need decades of data to say that a change in kelp is due to climate change rather than other cyclical factors, with Landsat, we have those data.”

“Many people have no idea how Earth imagery has improved their daily lives as it has become integrated into modern technologies. Like GPS and weather data, information from Landsat is woven into the fabric of our economy and society.”

“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.”

“The Landsat program has produced an unmatched record of observational coverage of Earth’s surface extending back to 1972, offering stunning satellite views of landscapes all over the world. This collaboration between NASA and the U.S. Geological Survey (USGS) has also yielded more than five decades of scientific discoveries as Earth’s climate has changed.”
